Extensions#

This section provides documentation for built-in extensions for Keep It Secret.

AWS Secrets Manager Wrapper#

Installation

Since AWS extension has external dependencies it needs to be explicitly named to be installed:

$ pip install keep_it_secret[aws]

API

class keep_it_secret.ext.aws.AWSSecrets(parent: Secrets | None = None)#

Concrete keep_it_secret.Secrets subclass that maps environment variables to AWS credentials.

property access_key_id: Any#

Maps AWS_ACCESS_KEY_ID environment variable. Optional, defaults to None.

Type:

str | None

property secret_access_key: Any#

Maps AWS_SECRET_ACCESS_KEY environment variable. Optional, defaults to None.

Type:

str | None

property session_token: Any#

Maps AWS_SESSION_TOKEN environment variable. Optional, defaults to None.

Type:

str | None

property region_name: Any#

Maps AWS_DEFAULT_REGION environment variable. Optional, defaults to None.

Type:

str | None

as_boto3_client_kwargs() → dict[str, Any]#

Return representation of the mapped variables for use in boto3.client() call.

class keep_it_secret.ext.aws.AWSSecretsManagerField(secret_id: str, default: ~typing.Any | None = None, decoder: ~typing.Callable = <function loads>, **field_options)#

Concrete keep_it_secret.Field subclass that uses AWS Secrets Manager to resolve the value.

Parameters:

  • secret_id – ID of the secret to fetch.

  • default – Default value. Defaults to None.

  • decoder – A callable to decode the fetched value. Defaults to json.loads().

classmethod new(secret_id: str, default: ~typing.Any | None = None, decoder: ~typing.Callable = <function loads>, **field_options) → AWSSecretsManagerField#

The field factory. Constructs the field in a manner which is compatible with type annotations.

Positional arguments, keyword arguments and field_options are passed to the constructor.

get_value(secrets: Secrets) → Any#

Retrieve, decode and return the secret specified by secret_id.

Depends on AWSSecrets to be declared in aws field on secrets or one of its parents.

Raises:

Hashicorp Vault Wrapper#

Installation

Since Vault extension has external dependencies it needs to be explicitly named to be installed:

$ pip install keep_it_secret[vault]

API

class keep_it_secret.ext.vault.VaultSecrets(parent: Secrets | None = None)#

Concrete keep_it_secret.Secrets subclass that maps environment variables to Vault credentials.

property url: Any#

Maps VAULT_URL environment variable.

Type:

str

property token: Any#

Maps VAULT_TOKEN environment variable.

Type:

str

property client_cert_path: Any#

Maps VAULT_CLIENT_CERT_PATH environment variable.

Type:

str | None

property client_key_path: Any#

Maps VAULT_CLIENT_KEY_PATH environment variable.

Type:

str | None

property server_cert_path: Any#

Maps VAULT_SERVER_CERT_PATH environment variable.

Type:

str | None

as_hvac_client_kwargs() → dict[str, Any]#

Return representation of the mapped variables for use in hvac.Client constructor.

get_client() → Client#

Return the hvac.Client instance configured using the credentials.

class keep_it_secret.ext.vault.VaultKV2Field(mount_point: str, path: str, version: str | None = None, default: Any | None = None, **field_options)#

Concrete keep_it_secret.Field subclass that uses Hashicorp Vault KV V2 secrets engine to resolve the value.

If as_type isn’t provided, the fetched value will be returned as-is ( i.e. as a dict). Otherwise, as_type should be a type which accepts kwargs representing the value’s keys in its constructor.

Parameters:

  • mount_point – Mount path for the secret engine.

  • path – Path to the secret to fetch.

  • version – Version identifier. Defaults to None (aka the newest version).

  • default – Default value. Defaults to None.

classmethod new(mount_point: str, path: str, version: str | None = None, default: Any | None = None, **field_options)#

The field factory. Constructs the field in a manner which is compatible with type annotations.

Positional arguments, keyword arguments and field_options are passed to the constructor.

cast(data: Any) → Any#

Cast data to the type specified in as_type argument of the constructor.

get_value(secrets: Secrets) → Any#

Retrieve, decode and return the secret stored in a KV V2 secrets engine mounted at mount_path under the path path.

Depends on VaultSecrets to be declared in vault field on secrets or one of its parents.

Raises:

Basic secrets loader#

keep_it_secret.ext.loader.load_secrets(package: str, env: str, app: str) → Any#

A basic secrets loader. Will attempt to import the secrets module and return the __secrets__ attribute.

Parameters:

  • package – The package which contains the module.

  • env – Environment identifier (e.g. development).

  • app – Application identifier (e.g. weather_service).
