# Command line arguments

The following command line arguments are supported by the Vault CSI provider.
If installing via the helm chart, they can be set using e.g.
`--set "csi.extraArgs={-debug=true}"`.

- `-debug` `(bool: false)` - Set to true to enable debug level logging.

- `-endpoint` `(string: "/tmp/vault.sock")` - Path to unix socket on which the
  provider will listen for gRPC calls from the driver.

- `-health-addr` `(string: ":8080")` - (v0.3.0+) The address of the HTTP listener
  for reporting health.

- `-health_addr` `(string: "")` - Deprecated, please use -health-addr. Slated
  for removal in 0.5.0.

- `-vault-addr` `(string: "https://127.0.0.1:8200")` - (v0.3.0+) Default address
  for connecting to Vault. Can be overridden per Secret Provider Class object.

- `-vault-mount` `(string: "kubernetes")` - (v0.3.0+) Default Vault mount path
  for Kubernetes authentication. Can be overridden per Secret Provider Class
  object.

- `-version` `(bool: false)` - prints the version information

- `-write-secrets` `(bool: true)` - (v0.3.0+) Write secrets directly to
  filesystem (true), or send secrets to CSI driver in gRPC response (false).
  Setting to false requires Secrets Store CSI Driver v0.0.21+. This flag will
  default to false from v0.4.0, and setting it to false will be required when
  using Secrets Store CSI Driver v0.0.24+.


# Secret Provider Class Configurations

The following parameters are supported by the Vault provider:

- `roleName` `(string: "")` - Name of the role to be used during login with Vault.

- `vaultAddress` `(string: "")` - The address of the Vault server.

- `vaultNamespace` `(string: "")` - The Vault [namespace](/docs/enterprise/namespaces) to use.

- `vaultSkipTLSVerify` `(string: "false")` - When set to true, skips verification of the Vault server
  certificate. Setting this to true is not recommended for production.

- `vaultCACertPath` `(string: "")` - The path on disk where the Vault CA certificate can be found
  when verifying the Vault server certificate.

- `vaultCADirectory` `(string: "")` - The directory on disk where the Vault CA certificate can be found
  when verifying the Vault server certificate.

- `vaultTLSClientCertPath` `(string: "")` - The path on disk where the client certificate can be found
  for mTLS communications with Vault.

- `vaultTLSClientKeyPath` `(string: "")` - The path on disk where the client key can be found
  for mTLS communications with Vault.

- `vaultTLSServerName` `(string: "")` - The name to use as the SNI host when connecting via TLS.

- `vaultKubernetesMountPath` `(string: "kubernetes")` - The name of the auth mount used for login.
  At this time only the Kubernetes auth method is supported.

- `objects` `(array)` - An array of secrets to retrieve from Vault.

  - `objectName` `(string: "")` - The alias of the object which can be referenced within the secret provider class and
  the name of the secret file.

  - `method` `(string: "GET")` - The type of HTTP request. Supported values include "GET" and "PUT".

  - `secretPath` `(string: "")` - The path in Vault where the secret is located.
    For secrets that are retrieved via HTTP GET method, the `secretPath` can include optional URI parameters,
    for example, the [version of the KV2 secret](https://www.vaultproject.io/api-docs/secret/kv/kv-v2#read-secret-version):

    ```yaml
    objects: |
      - objectName: "app-secret"
        secretPath: "secret/data/test?version=1"
        secretKey: "password"
    ```

  - `secretKey` `(string: "")` - The key in the Vault secret to extract. If omitted, the whole response from Vault will be written as JSON.

  - `secretArgs` `(map: {})` - Additional arguments to be sent to Vault for a specific secret. Arguments can vary
    for different secret engines. For example:

    ```yaml
    secretArgs:
      common_name: 'test.example.com'
      ttl: '24h'
    ```

    ~> `secretArgs` are sent as part of the HTTP request body. Therefore, they are only effective for HTTP PUT/POST requests, for instance,
        the [request used to generate a new certificate](https://www.vaultproject.io/api-docs/secret/pki#generate-certificate).
        To supply additional parameters for secrets retrieved via HTTP GET, include optional URI paramters in [`secretPath`](#secretpath).
