To set up the authentication method for token renewal and to define secret templates, the Infisical agent requires a YAML configuration file containing properties defined below.
While specifying an authentication method is mandatory to start the agent, configuring sinks and secret templates are optional.
| Field | Description |
| ---------------------------- | ----------- |
| `infisical.address` | The URL of the Infisical service. Default: `"https://app.infisical.com"`. |
| `auth.type` | The type of authentication method used. Only `"universal-auth"` type is currently available |
| `auth.config.client-id` | The file path where the universal-auth client id is stored. |
| `auth.config.client-secret` | The file path where the universal-auth client secret is stored. |
| `auth.config.remove_client_secret_on_read` | This will instruct the agent to remove the client secret from disk. |
| `sinks[].type` | The type of sink in a list of sinks. Each item specifies a sink type. Currently, only `"file"` type is available. |
| `sinks[].config.path` | The file path where the access token should be stored for each sink in the list. |
| `templates[].source-path` | The path to the template file that should be used to render secrets. |
| `templates[].destination-path` | The path where the rendered secrets from the source template will be saved to. |
| `templates[].config.polling-interval` | How frequently to check for secret changes. Default: `5 minutes` (optional) |
| `templates[].config.execute.command` | The command to execute when secret change is detected (optional) |
| `templates[].config.execute.timeout` | How long in seconds to wait for command to execute before timing out (optional) |

## Quick start Infisical Agent
To install the Infisical agent, you must first install the [Infisical CLI](../cli/overview) in the desired environment where you'd like the agent to run. This is because the Infisical agent is a sub-command of the Infisical CLI.
