description: "Learn how to generate dynamic secret leases in Infisical and sync them to your Kubernetes cluster."
|
||||
---
|
||||
## Overview
|
||||
|
||||
The **InfisicalDynamicSecret** CRD allows you to easily create and manage dynamic secret leases in Infisical and automatically sync them to your Kubernetes cluster as native **Kubernetes Secret** resources.
|
||||
This means any Pod, Deployment, or other Kubernetes resource can make use of dynamic secrets from Infisical just like any other K8s secret.
|
||||
|
||||
This CRD offers the following features:
|
||||
- **Generate a dynamic secret lease** in Infisical and track its lifecycle.
|
||||
- **Write** the dynamic secret from Infisical to your cluster as native Kubernetes secret.
|
||||
- **Automatically rotate** the dyanmic secret value before it expires to make sure your cluster always has valid credentials.
|
||||
- **Optionally trigger redeployments** of any workloads that consume the secret if you enable auto-reload.
|
||||
|
||||
### Prerequisites
|
||||
- The operator is installed on to your Kubernetes cluster
|
||||
- You have already configured a dynamic secret in Infisical
|
||||
|
||||
## Configure Dynamic Secret CRD
|
||||
|
||||
The example below shows a sample **InfisicalDynamicSecret** CRD that creates a dynamic secret lease in Infisical, and syncs the lease to your Kubernetes cluster.
|
||||
|
||||
```yaml dynamic-secret-crd.yaml
|
||||
apiVersion: secrets.infisical.com/v1alpha1
|
||||
kind: InfisicalDynamicSecret
|
||||
metadata:
|
||||
name: infisicaldynamicsecret
|
||||
spec:
|
||||
hostAPI: https://app.infisical.com/api # Optional, defaults to https://app.infisical.com/api
|
||||
|
||||
dynamicSecret:
|
||||
secretName: <dynamic-secret-name>
|
||||
projectId: <project-id>
|
||||
secretsPath: <path/to/dynamic-secret> # Root directory is /
|
||||
environmentSlug: <env-slug>
|
||||
|
||||
# Lease revocation policy defines what should happen to leases created by the operator if the CRD is deleted.
|
||||
# If set to "Revoke", leases will be revoked when the InfisicalDynamicSecret CRD is deleted.
|
||||
leaseRevocationPolicy: Revoke
|
||||
|
||||
# Lease TTL defines how long the lease should last for the dynamic secret.
|
||||
# This value must be less than 1 day, and if a max TTL is defined on the dynamic secret, it must be below the max TTL.
|
||||
leaseTTL: 1m
|
||||
|
||||
# A reference to the secret that the dynamic secret lease should be stored in.
|
||||
# If the secret doesn't exist, it will automatically be created.
|
||||
managedSecretReference:
|
||||
secretName: <secret-name>
|
||||
secretNamespace: default # Must be the same namespace as the InfisicalDynamicSecret CRD.
|
||||
creationPolicy: Orphan
|
||||
|
||||
# Only have one authentication method defined or you are likely to run into authentication issues.
|
||||
# Remove all except one authentication method.
|
||||
authentication:
|
||||
awsIamAuth:
|
||||

|
||||
azureAuth:
|
||||

|
||||
universalAuth:
|
||||
credentialsRef:
|
||||
secretName: <secret-name> # universal-auth-credentials
|
||||
secretNamespace: <secret-namespace> # default
|
||||
```
|
||||
|
||||
Apply the InfisicalDynamicSecret CRD to your cluster.
|
||||
```bash
|
||||
kubectl apply -f dynamic-secret-crd.yaml
|
||||
```
|
||||
|
||||
After applying the InfisicalDynamicSecret CRD, you should notice that the dynamic secret lease has been created in Infisical and synced to your Kubernetes cluster. You can verify that the lease has been created by doing:
|
||||
```bash
|
||||
kubectl get secret <managed-secret-name> -o yaml
|
||||
```
|
||||
|
||||
After getting the secret, you should should see that the secret has data that contains the lease credentials.
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
data:
|
||||
DB_PASSWORD: VHhETjZ4c2xsTXpOSWdPYW5LLlRyNEc2alVKYml6WiQjQS0tNTdodyREM3ZLZWtYSi4hTkdyS0F+TVFsLU9CSA==

||||
DB_USERNAME: cHg4Z0dJTUVBcHdtTW1aYnV3ZWRsekJRRll6cW4wFEE=
|
||||
kind: Secret
|
||||
# .....
|
||||
```
|
||||
|
||||
### InfisicalDynamicSecret CRD properties
|
||||
|
||||
<Accordion title="hostAPI">
|
||||
If you are fetching secrets from a self-hosted instance of Infisical set the value of `hostAPI` to
|
||||
` https://your-self-hosted-instace.com/api`
|
||||
|
||||
When `hostAPI` is not defined the operator fetches secrets from Infisical Cloud.
|
||||
|
||||
<Accordion title="Advanced use case">
|
||||
If you have installed your Infisical instance within the same cluster as the Infisical operator, you can optionally access the Infisical backend's service directly without having to route through the public internet.
|
||||
To achieve this, use the following address for the hostAPI field:
|
||||
|
||||
``` bash
|
||||
http://<backend-svc-name>.<namespace>.svc.cluster.local:4000/api
|
||||
```
|
||||
|
||||
Make sure to replace `<backend-svc-name>` and `<namespace>` with the appropriate values for your backend service and namespace.
|
||||
|
||||
</Accordion>
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="leaseTTL">
|
||||
The `leaseTTL` is a string-formatted duration that defines the time the lease should last for the dynamic secret.
|
||||
|
||||
The format of the field is `[duration][unit]` where `duration` is a number and `unit` is a string representing the unit of time.
|
||||
|
||||
The following units are supported:
|
||||
- `s` for seconds (must be at least 5 seconds)
|
||||
- `m` for minutes
|
||||
- `h` for hours
|
||||
- `d` for days
|
||||
|
||||
<Note>
|
||||
The lease duration at most be 1 day (24 hours). And the TTL must be less than the max TTL defined on the dynamic secret.
|
||||
</Note>
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="managedSecretReference">
|
||||
The `managedSecretReference` field is used to define the Kubernetes secret where the dynamic secret lease should be stored. The required fields are `secretName` and `secretNamespace`.
|
||||
|
||||
```yaml
|
||||
spec:
|
||||
managedSecretReference:
|
||||
secretName: <secret-name>
|
||||
secretNamespace: default
|
||||
```
|
||||
|
||||
<Accordion title="managedSecretReference.secretName">
|
||||
The name of the Kubernetes secret where the dynamic secret lease should be stored.
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="managedSecretReference.secretNamespace">
|
||||
The namespace of the Kubernetes secret where the dynamic secret lease should be stored.
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="managedSecretReference.creationPolicy">
|
||||
Creation polices allow you to control whether or not owner references should be added to the managed Kubernetes secret that is generated by the Infisical operator.
|
||||
This is useful for tools such as ArgoCD, where every resource requires an owner reference; otherwise, it will be pruned automatically.
|
||||
|
||||
#### Available options
|
||||
- `Orphan` (default)
|
||||
- `Owner`
|
||||
|
||||
<Tip>
|
||||
When creation policy is set to `Owner`, the `InfisicalSecret` CRD must be in
|
||||
the same namespace as where the managed kubernetes secret.
|
||||
</Tip>
|
||||
|
||||
This field is optional.
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="managedSecretReference.secretType">
|
||||
Override the default Opaque type for managed secrets with this field. Useful for creating kubernetes.io/dockerconfigjson secrets.
|
||||
|
||||
This field is optional.
|
||||
</Accordion>
|
||||
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="leaseRevocationPolicy">
|
||||
|
||||
The field is optional and will default to `None` if not defined.
|
||||
|
||||
The lease revocation policy defines what the operator should do with the leases created by the operator, when the InfisicalDynamicSecret CRD is deleted.
|
||||
|
||||
Valid values are `None` and `Revoke`.
|
||||
|
||||
Behavior of each policy:
|
||||
- `None`: The operator will not override existing secrets in Infisical. If a secret with the same key already exists, the operator will skip pushing that secret, and the secret will not be managed by the operator.
|
||||
- `Revoke`: The operator will revoke the leases created by the operator when the InfisicalDynamicSecret CRD is deleted.
|
||||
|
||||
```yaml
|
||||
spec:
|
||||
leaseRevocationPolicy: Revoke
|
||||
```
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="dynamicSecret">

### Applying the InfisicalDynamicSecret CRD to your cluster
|
||||
|
||||
Once you have configured the `InfisicalDynamicSecret` CRD with the required fields, you can apply it to your cluster. After applying, you should notice that a lease has been created in Infisical and synced to your Kubernetes cluster.
|
||||
|
||||
```bash
|
||||
kubectl apply -f dynamic-secret-crd.yaml
|
||||
```
|
||||
|
||||
## Auto redeployment
|
||||
|
||||
Deployments referring to Kubernetes secrets containing Infisical dynamic secrets don't automatically reload when the dynamic secret lease expires. This means your deployment may use expired dynamic secrets unless manually redeployed.
|
||||
To address this, we've added functionality to automatically redeploy your deployment when the associated Kubernetes secret containing your Infisical dynamic secret updates.
|
||||
|
||||
#### Enabling auto redeploy
|
||||
|
||||
To enable auto redeployment you simply have to add the following annotation to the deployment that consumes a managed secret
|
||||
|
||||
```yaml
|
||||
secrets.infisical.com/auto-reload: "true"
|
||||
```
|
||||
|
||||
<Accordion title="Deployment example with auto redeploy enabled">
|
||||
```yaml
|
||||
apiVersion: apps/v1
|
||||
kind: Deployment
|
||||
metadata:
|
||||
name: nginx-deployment
|
||||
labels:
|
||||
app: nginx
|
||||
annotations:
|
||||
secrets.infisical.com/auto-reload: "true" # <- redeployment annotation

|
||||
envFrom:
|
||||
- secretRef:
|
||||
name: managed-secret # The name of your managed secret, the same that you're using in your InfisicalDynamicSecret CRD (spec.managedSecretReference.secretName)
|
||||
ports:
|
||||
- containerPort: 80
|
||||
```
|
||||
</Accordion>
|
||||
<Info>
|
||||
#### How it works
|
||||
When the lease changes, the operator will check to see which deployments are using the operator-managed Kubernetes secret that received the update.
|
||||
Then, for each deployment that has this annotation present, a rolling update will be triggered. A redeployment won't happen if the lease is renewed, only if it's recreated.

## Push Secrets to Infisical
|
||||
|
||||
|
||||
### Example usage
|
||||
|
||||
Below is a sample InfisicalPushSecret CRD that pushes secrets defined in a Kubernetes secret to Infisical.
|
||||
|
||||
After filling out the fields in the InfisicalPushSecret CRD, you can apply it directly to your cluster.
|
||||
|
||||
Before applying the InfisicalPushSecret CRD, you need to create a Kubernetes secret containing the secrets you want to push to Infisical. An example can be seen below the InfisicalPushSecret CRD.
|
||||
|
||||
```yaml infisical-push-secret.yaml
|
||||
apiVersion: secrets.infisical.com/v1alpha1
|
||||
kind: InfisicalPushSecret
|
||||
metadata:
|
||||
name: infisical-push-secret-demo
|
||||
spec:
|
||||
resyncInterval: 1m
|
||||
hostAPI: https://app.infisical.com/api
|
||||
|
||||
# Optional, defaults to no replacement.
|
||||
updatePolicy: Replace # If set to replace, existing secrets inside Infisical will be replaced by the value of the PushSecret on sync.
|
||||
|
||||
# Optional, defaults to no deletion.
|
||||
deletionPolicy: Delete # If set to delete, the secret(s) inside Infisical managed by the operator, will be deleted if the InfisicalPushSecret CRD is deleted.

|
||||
### InfisicalPushSecret CRD properties
|
||||
|
||||
<Accordion title="hostAPI">
|
||||
If you are fetching secrets from a self-hosted instance of Infisical set the value of `hostAPI` to
|
||||
` https://your-self-hosted-instace.com/api`
|
||||
|
||||
When `hostAPI` is not defined the operator fetches secrets from Infisical Cloud.
|
||||
|
||||
<Accordion title="Advanced use case">
|
||||
If you have installed your Infisical instance within the same cluster as the Infisical operator, you can optionally access the Infisical backend's service directly without having to route through the public internet.
|
||||
To achieve this, use the following address for the hostAPI field:
|
||||
|
||||
``` bash
|
||||
http://<backend-svc-name>.<namespace>.svc.cluster.local:4000/api
|
||||
```
|
||||
|
||||
Make sure to replace `<backend-svc-name>` and `<namespace>` with the appropriate values for your backend service and namespace.
|
||||
|
||||
</Accordion>
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="resyncInterval">
|
||||
|
||||
The `resyncInterval` is a string-formatted duration that defines the time between each resync.
|
||||
|
||||
The format of the field is `[duration][unit]` where `duration` is a number and `unit` is a string representing the unit of time.
|
||||
|
||||
The following units are supported:
|
||||
- `s` for seconds (must be at least 5 seconds)
|
||||
- `m` for minutes
|
||||
- `h` for hours
|
||||
- `d` for days
|
||||
- `w` for weeks
|
||||
|
||||
The default value is `1m` (1 minute).
|
||||
|
||||
Valid intervals examples:
|
||||
```yaml
|
||||
resyncInterval: 5s # 10 seconds
|
||||
resyncInterval: 10s # 10 seconds
|
||||
resyncInterval: 5m # 5 minutes
|
||||
resyncInterval: 1h # 1 hour
|
||||
resyncInterval: 1d # 1 day
|
||||
```
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="updatePolicy">
|
||||
|
||||
The field is optional and will default to `None` if not defined.
|
||||
|
||||
The update policy defines how the operator should handle conflicting secrets when pushing secrets to Infisical.
|
||||
|
||||
Valid values are `None` and `Replace`.
|
||||
|
||||
Behavior of each policy:
|
||||
- `None`: The operator will not override existing secrets in Infisical. If a secret with the same key already exists, the operator will skip pushing that secret, and the secret will not be managed by the operator.
|
||||
- `Replace`: The operator will replace existing secrets in Infisical with the new secrets. If a secret with the same key already exists, the operator will update the secret with the new value.
|
||||
|
||||
```yaml
|
||||
spec:
|
||||
updatePolicy: Replace
|
||||
```
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="deletionPolicy">
|
||||
|
||||
This field is optional and will default to `None` if not defined.
|
||||
|
||||
The deletion policy defines what the operator should do in case the InfisicalPushSecret CRD is deleted.
|
||||
|
||||
Valid values are `None` and `Delete`.
|
||||
|
||||
Behavior of each policy:
|
||||
- `None`: The operator will not delete the secrets in Infisical when the InfisicalPushSecret CRD is deleted.
|
||||
- `Delete`: The operator will delete the secrets in Infisical that are managed by the operator when the InfisicalPushSecret CRD is deleted.
|
||||
|
||||
```yaml
|
||||
spec:
|
||||
deletionPolicy: Delete
|
||||
```

The Infisical Secrets Operator is a Kubernetes controller that retrieves secrets from Infisical and stores them in a designated cluster.
|
||||
It uses an `InfisicalSecret` resource to specify authentication and storage methods.
|
||||
The operator continuously updates secrets and can also reload dependent deployments automatically.
|
||||
|
||||

|
||||
If you are already using the External Secrets operator, you can view the
|

## Install Operator
|
||||
|
||||
The operator can be install via [Helm](https://helm.sh) or [kubectl](https://github.com/kubernetes/kubectl)
|
||||
|
||||
<Tabs>
|
||||
<Tab title="Helm (recommended)">
|
||||
**Install the latest Infisical Helm repository**
|
||||
```bash
|
||||
helm repo add infisical-helm-charts 'https://dl.cloudsmith.io/public/infisical/helm-charts/helm/charts/'
|
||||
|
||||
helm repo update
|
||||
```
|
||||
|
||||
**Install the Helm chart**
|
||||
|
||||
To select a specific version, view the application versions [here](https://hub.docker.com/r/infisical/kubernetes-operator/tags) and chart versions [here](https://cloudsmith.io/~infisical/repos/helm-charts/packages/detail/helm/secrets-operator/#versions)
|
||||
|
||||
```bash
|
||||
helm install --generate-name infisical-helm-charts/secrets-operator
|
||||
```
|
||||
|
||||
```bash

||||
# Example installing app version v0.2.0 and chart version 0.1.4
|
||||
helm install --generate-name infisical-helm-charts/secrets-operator --version=0.1.4 --set controllerManager.manager.image.tag=v0.2.0
|
||||
```
|
||||
|
||||
**Namespace-scoped Installation**
|
||||
|
||||
The operator can be configured to watch and manage secrets in a specific namespace instead of having cluster-wide access. This is useful for:
|
||||
|
||||
- **Enhanced Security**: Limit the operator's permissions to only specific namespaces instead of cluster-wide access
|
||||
- **Multi-tenant Clusters**: Run separate operator instances for different teams or applications
|
||||
- **Resource Isolation**: Ensure operators in different namespaces don't interfere with each other
|
||||
- **Development & Testing**: Run development and production operators side by side in isolated namespaces
|
||||
|
||||
**Note**: For multiple namespace-scoped installations, only the first installation should install CRDs. Subsequent installations should set `installCRDs: false` to avoid conflicts.
|
||||
|
||||
```bash
|
||||
# First namespace installation (with CRDs)
|
||||
helm install operator-namespace1 infisical-helm-charts/secrets-operator \
|
||||
--namespace first-namespace \
|
||||
--set scopedNamespace=first-namespace \
|
||||
--set scopedRBAC=true
|
||||
|
||||
# Subsequent namespace installations
|
||||
helm install operator-namespace2 infisical-helm-charts/secrets-operator \
|
||||
--namespace another-namespace \
|
||||
--set scopedNamespace=another-namespace \
|
||||
--set scopedRBAC=true \
|
||||
--set installCRDs=false
|
||||
```
|
||||
|
||||
When scoped to a namespace, the operator will:
|
||||
|
||||
- Only watch InfisicalSecrets in the specified namespace
|
||||
- Only create/update Kubernetes secrets in that namespace
|
||||
- Only access deployments in that namespace
|
||||
|
||||
The default configuration gives cluster-wide access:
|
||||
|
||||
```yaml
|
||||
installCRDs: true # Install CRDs (set to false for additional namespace installations)
|
||||
scopedNamespace: "" # Empty for cluster-wide access
|
||||
scopedRBAC: false # Cluster-wide permissions
|
||||
```
|
||||
|
||||
If you want to install operators in multiple namespaces simultaneously:
|
||||
- Make sure to set `installCRDs: false` for all but one of the installations to avoid conflicts, as CRDs are cluster-wide resources.
|
||||
- Use unique release names for each installation (e.g., operator-namespace1, operator-namespace2).
|
||||
|
||||
</Tab>
|
||||
<Tab title="Kubectl">
|
||||
For production deployments, it is highly recommended to set the version of the Kubernetes operator manually instead of pointing to the latest version.
|
||||
Doing so will help you avoid accidental updates to the newest release which may introduce unintended breaking changes. View all application versions [here](https://hub.docker.com/r/infisical/kubernetes-operator/tags).
|
||||
|
||||
The command below will install the most recent version of the Kubernetes operator.
|
||||
However, to set the version manually, download the manifest and set the image tag version of `infisical/kubernetes-operator` according to your desired version.
|
||||
|
||||
Once you apply the manifest, the operator will be installed in `infisical-operator-system` namespace.
|
||||
|
||||
```
|
||||
kubectl apply -f https://raw.githubusercontent.com/Infisical/infisical/main/k8-operator/kubectl-install/install-secrets-operator.yaml

## Sync Infisical Secrets to your cluster

### Propagating labels & annotations
|
||||
|
||||
The operator will transfer all labels & annotations present on the `InfisicalSecret` CRD to the managed Kubernetes secret to be created.
|
||||
Thus, if a specific label is required on the resulting secret, it can be applied as demonstrated in the following example:

To connect to Infisical instances behind a private/self-signed certificate, you can configure the TLS settings in the `InfisicalSecret` CRD

## Push Secrets to Infisical
|

## Propagating labels & annotations
|
||||
|
||||
The operator will transfer all labels & annotations present on the `InfisicalSecret` CRD to the managed Kubernetes secret to be created.
|
||||
Thus, if a specific label is required on the resulting secret, it can be applied as demonstrated in the following example:
|
||||
|
||||
### Example usage
|
||||
|
||||
Below is a sample InfisicalPushSecret CRD that pushes secrets defined in a Kubernetes secret to Infisical.
|
||||
|
||||
After filling out the fields in the InfisicalPushSecret CRD, you can apply it directly to your cluster.
|
||||
|
||||
Before applying the InfisicalPushSecret CRD, you need to create a Kubernetes secret containing the secrets you want to push to Infisical. An example can be seen below the InfisicalPushSecret CRD.
|
||||
|
||||
```bash
|
||||
kubectl apply -f source-secret.yaml
|
||||
```
|
||||
|
||||
After applying the soruce-secret.yaml file, you are ready to apply the InfisicalPushSecret CRD.
|
||||
|
||||
```bash
|
||||
kubectl apply -f infisical-push-secret.yaml
|
||||
```
|
||||
|
||||
After applying the InfisicalPushSecret CRD, you should notice that the secrets you have defined in your source-secret.yaml file have been pushed to your specified destination in Infisical.

### InfisicalPushSecret CRD properties
|
||||
|
||||
<Accordion title="hostAPI">
|
||||
If you are fetching secrets from a self-hosted instance of Infisical set the value of `hostAPI` to
|
||||
` https://your-self-hosted-instace.com/api`
|
||||
|
||||
When `hostAPI` is not defined the operator fetches secrets from Infisical Cloud.
|
||||
|
||||
<Accordion title="Advanced use case">
|
||||
If you have installed your Infisical instance within the same cluster as the Infisical operator, you can optionally access the Infisical backend's service directly without having to route through the public internet.
|
||||
To achieve this, use the following address for the hostAPI field:
|
||||
|
||||
``` bash
|
||||
http://<backend-svc-name>.<namespace>.svc.cluster.local:4000/api
|
||||
```
|
||||
|
||||
Make sure to replace `<backend-svc-name>` and `<namespace>` with the appropriate values for your backend service and namespace.
|
||||
|
||||
</Accordion>
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="resyncInterval">
|
||||
|
||||
The `resyncInterval` is a string-formatted duration that defines the time between each resync.
|
||||
|
||||
The format of the field is `[duration][unit]` where `duration` is a number and `unit` is a string representing the unit of time.
|
||||
|
||||
The following units are supported:
|
||||
- `s` for seconds (must be at least 5 seconds)
|
||||
- `m` for minutes
|
||||
- `h` for hours
|
||||
- `d` for days
|
||||
- `w` for weeks
|
||||
|
||||
The default value is `1m` (1 minute).
|
||||
|
||||
Valid intervals examples:
|
||||
```yaml
|
||||
resyncInterval: 5s # 10 seconds
|
||||
resyncInterval: 10s # 10 seconds
|
||||
resyncInterval: 5m # 5 minutes
|
||||
resyncInterval: 1h # 1 hour
|
||||
resyncInterval: 1d # 1 day
|
||||
```
|
||||
</Accordion>
|
||||
|
||||
<Accordion title="updatePolicy">
|
||||
|
||||
The field is optional and will default to `None` if not defined.
|
||||
|
||||
The update policy defines how the operator should handle conflicting secrets when pushing secrets to Infisical.
|
||||
|
||||
Valid values are `None` and `Replace`.
|
||||
|
||||
Behavior of each policy:
|
||||
- `None`: The operator will not override existing secrets in Infisical. If a secret with the same key already exists, the operator will skip pushing that secret, and the secret will not be managed by the operator.
|
||||
- `Replace`: The operator will replace existing secrets in Infisical with the new secrets. If a secret with the same key already exists, the operator will update the secret with the new value.
|
||||
|
||||
```yaml
|
||||
spec:
|
||||
updatePolicy: Replace
|
||||
```

</Accordion>
|
||||
|
||||
<Accordion title="deletionPolicy">
|
||||
|
||||
This field is optional and will default to `None` if not defined.
|
||||
|
||||
The deletion policy defines what the operator should do in case the InfisicalPushSecret CRD is deleted.
|
||||
|
||||
Valid values are `None` and `Delete`.
|
||||
|
||||
Behavior of each policy:
|
||||
- `None`: The operator will not delete the secrets in Infisical when the InfisicalPushSecret CRD is deleted.
|
||||
- `Delete`: The operator will delete the secrets in Infisical that are managed by the operator when the InfisicalPushSecret CRD is deleted.

Once you have configured the `InfisicalPushSecret` CRD with the required fields, you can apply it to your cluster.
|
||||
After applying, you should notice that the secrets have been pushed to Infisical.
|
||||
|
||||
```bash
|
||||
kubectl apply -f source-push-secret.yaml # The secret that you're referencing in the InfisicalPushSecret CRD push.secret field

### Connecting to instances with private/self-signed certificate
|
||||
|
||||
To connect to Infisical instances behind a private/self-signed certificate, you can configure the TLS settings in the `InfisicalPushSecret` CRD
|
||||
to point to a CA certificate stored in a Kubernetes secret resource.

## Global configuration
|
||||
|
||||
To configure global settings that will apply to all instances of `InfisicalSecret`, you can define these configurations in a Kubernetes ConfigMap.
|
||||
For example, you can configure all `InfisicalSecret` instances to fetch secrets from a single backend API without specifying the `hostAPI` parameter for each instance.
|
||||
|
||||
### Available global properties
|
||||
|
||||
| Property | Description | Default value |
|
||||
| -------- | --------------------------------------------------------------------------------- | ----------------------------- |
|
||||
| hostAPI | If `hostAPI` in `InfisicalSecret` instance is left empty, this value will be used | https://app.infisical.com/api |
|
||||
|
||||
### Applying global configurations
|
||||
|
||||
All global configurations must reside in a Kubernetes ConfigMap named `infisical-config` in the namespace `infisical-operator-system`.
|
||||
To apply global configuration to the operator, copy the following yaml into `infisical-config.yaml` file.
|
||||
|
||||
```yaml infisical-config.yaml
|
||||

|
||||
data:
|

hostAPI: https://example.com/api # <-- global hostAPI
|
||||
```
|
||||
|
||||
Then apply this change via kubectl by running the following

## Troubleshoot operator
|
||||
|
||||
If the operator is unable to fetch secrets from the API, it will not affect the managed Kubernetes secret.
|
||||
It will continue attempting to reconnect to the API indefinitely.
|
||||
The InfisicalSecret resource uses the `status.conditions` field to report its current state and any errors encountered.
|
||||
This would result in the following managed secret to be created:
|
||||
|
||||
```yaml
|
||||
$ kubectl get infisicalSecrets
|
||||
NAME AGE
|
||||
infisicalsecret-sample 12s
|
||||
|
||||
$ kubectl describe infisicalSecret infisicalsecret-sample

|
||||
---
|
||||
|
||||
The Infisical Operator is a collection of Kubernetes controllers that streamline how secrets are managed between Infisical and your Kubernetes cluster.
|
||||
It provides multiple Custom Resource Definitions (CRDs) which enable you to:
|
||||
|
||||
- **Sync** secrets from Infisical into Kubernetes (`InfisicalSecret`).
|
||||
- **Push** new secrets from Kubernetes to Infisical (`InfisicalPushSecret`).
|
||||
- **Manage** dynamic secrets and automatically create time-bound leases (`InfisicalDynamicSecret`).
|
||||
|
||||
When these CRDs are configured, the Infisical Operator will continuously monitors for changes and performs necessary updates to keep your Kubernetes secrets up to date.
|
||||
It can also automatically reload dependent Deployments resources whenever relevant secrets are updated.
|
||||
|
||||
<Note>
|
||||
If you are already using the External Secrets operator, you can view the
|
||||
integration documentation for it
|
||||
[here](https://external-secrets.io/latest/provider/infisical/).
|
||||
</Note>
|
||||
|
||||
## Install
|
||||
|
||||
The operator can be install via [Helm](https://helm.sh). Helm is a package manager for Kubernetes that allows you to define, install, and upgrade Kubernetes applications.
|
||||
|
||||
**Install the latest Helm repository**
|
||||
```bash
|
||||
helm repo add infisical-helm-charts 'https://dl.cloudsmith.io/public/infisical/helm-charts/helm/charts/'
|
||||
```
|
||||
|
||||
```bash
|
||||
helm repo update
|
||||
```
|
||||
|
||||
The operator can be installed either cluster-wide or restricted to a specific namespace.
|
||||
If you require stronger isolation and stricter access controls, a namespace-scoped installation may make more sense.
|
||||
|
||||
<Tabs>
|
||||
<Tab title="Cluster Wide Installation">
|
||||
```bash
|
||||
helm install --generate-name infisical-helm-charts/secrets-operator
|
||||
```
|
||||
</Tab>
|
||||
<Tab title="Namespace Scoped Installation">
|
||||
The operator can be configured to watch and manage secrets in a specific namespace instead of having cluster-wide access. This is useful for:
|
||||
|
||||
- **Enhanced Security**: Limit the operator's permissions to only specific namespaces instead of cluster-wide access
|
||||
- **Multi-tenant Clusters**: Run separate operator instances for different teams or applications
|
||||
- **Resource Isolation**: Ensure operators in different namespaces don't interfere with each other
|
||||
- **Development & Testing**: Run development and production operators side by side in isolated namespaces
|
||||
|
||||
**Note**: For multiple namespace-scoped installations, only the first installation should install CRDs. Subsequent installations should set `installCRDs: false` to avoid conflicts.
|
||||
|
||||
```bash
|
||||
# First namespace installation (with CRDs)
|
||||
helm install operator-namespace1 infisical-helm-charts/secrets-operator \
|
||||
--namespace first-namespace \
|
||||
--set scopedNamespace=first-namespace \
|
||||
--set scopedRBAC=true
|
||||
|
||||
# Subsequent namespace installations
|
||||
helm install operator-namespace2 infisical-helm-charts/secrets-operator \
|
||||
--namespace another-namespace \
|
||||
--set scopedNamespace=another-namespace \
|
||||
--set scopedRBAC=true \
|
||||
--set installCRDs=false
|
||||
```
|
||||
|
||||
When scoped to a namespace, the operator will:
|
||||
|
||||
- Only watch InfisicalSecrets in the specified namespace
|
||||
- Only create/update Kubernetes secrets in that namespace
|
||||
- Only access deployments in that namespace
|
||||
|
||||
The default configuration gives cluster-wide access:
|
||||
|
||||
```yaml
|
||||
installCRDs: true # Install CRDs (set to false for additional namespace installations)
|
||||
scopedNamespace: "" # Empty for cluster-wide access
|
||||
scopedRBAC: false # Cluster-wide permissions
|
||||
```
|
||||
|
||||
If you want to install operators in multiple namespaces simultaneously:
|
||||
- Make sure to set `installCRDs: false` for all but one of the installations to avoid conflicts, as CRDs are cluster-wide resources.
|
||||
- Use unique release names for each installation (e.g., operator-namespace1, operator-namespace2).
|
||||
|
||||
</Tab>
|
||||
</Tabs>
|
||||
|
||||
## Custom Resource Definitions
|
||||
|
||||
Currently the operator supports the following CRD's. We are constantly expanding the functionality of the operator, and this list will be updated as new CRD's are added.
|
||||
|
||||
1. [InfisicalSecret](/integrations/platforms/kubernetes/infisical-secret-crd): Sync secrets from Infisical to a Kubernetes secret.
|
||||
2. [InfisicalPushSecret](/integrations/platforms/kubernetes/infisical-push-secret-crd): Push secrets from a Kubernetes secret to Infisical.
|
||||
3. [InfisicalDynamicSecret](/integrations/platforms/kubernetes/infisical-dynamic-secret-crd): Sync dynamic secrets and create leases automatically in Kubernetes.
|
||||
|
||||
## General Configuration
|
||||
### Private/self-signed certificate
|
||||
To connect to Infisical instances behind a private/self-signed certificate, you can configure the TLS settings in the CRD
|
||||
to point to a CA certificate stored in a Kubernetes secret resource.
|
||||
|
||||
```yaml
|
||||
---
|
||||
spec:
|
||||
hostAPI: https://app.infisical.com/api
|
||||
tls:
|
||||
caRef:
|
||||
secretName: custom-ca-certificate
|
||||
secretNamespace: default
|
||||
key: ca.crt
|
||||
---
|
||||
```
|
||||
|
||||
|
||||
## Global configuration
|
||||
|
||||
To configure global settings that will apply to all instances of `InfisicalSecret`, you can define these configurations in a Kubernetes ConfigMap.
|
||||
For example, you can configure all `InfisicalSecret` instances to fetch secrets from a single backend API without specifying the `hostAPI` parameter for each instance.
|
||||
|
||||
### Available global properties
|
||||
|
||||
| Property | Description | Default value |
|
||||
| -------- | --------------------------------------------------------------------------------- | ----------------------------- |
|
||||
| hostAPI | If `hostAPI` in `InfisicalSecret` instance is left empty, this value will be used | https://app.infisical.com/api |
|
||||
|
||||
### Applying global configurations
|
||||
|
||||
All global configurations must reside in a Kubernetes ConfigMap named `infisical-config` in the namespace `infisical-operator-system`.
|
||||
To apply global configuration to the operator, copy the following yaml into `infisical-config.yaml` file.
|
||||
|
||||
```yaml infisical-config.yaml
|
||||
apiVersion: v1
|
||||
kind: Namespace
|
||||
metadata:
|
||||
name: infisical-operator-system
|
||||

|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: infisical-config
|
||||
namespace: infisical-operator-system
|
||||
data:
|
||||
hostAPI: https://example.com/api # <-- global hostAPI
|
||||
```
|
||||
|
||||
Then apply this change via kubectl by running the following
|
||||
|
||||
```bash
|
||||
kubectl apply -f infisical-config.yaml
|
||||
```
|
||||
|
||||
## Troubleshoot operator
|
||||
|
||||
If the operator is unable to fetch secrets from the API, it will not affect the managed Kubernetes secret.
|
||||

|
||||
The InfisicalSecret resource uses the `status.conditions` field to report its current state and any errors encountered.
