secrets_stores special

Centralized secrets management.

aws_secrets_store

AWS Secrets Store implementation.

AWSSecretsStore (ServiceConnectorSecretsStore)

Secrets store implementation that uses the AWS Secrets Manager API.

This secrets store implementation uses the AWS Secrets Manager API to store secrets. It allows a single AWS Secrets Manager region "instance" to be shared with other ZenML deployments as well as other third party users and applications.

Here are some implementation highlights:

  • the name/ID of an AWS secret is derived from the ZenML secret UUID and a zenml prefix in the form zenml/{zenml_secret_uuid}. This clearly identifies a secret as being managed by ZenML in the AWS console.

  • the Secrets Store also uses AWS secret tags to store additional metadata associated with a ZenML secret. The zenml tag in particular is used to identify and group all secrets that belong to the same ZenML deployment.

  • all secret key-values configured in a ZenML secret are stored as a single JSON string value in the AWS secret value.

azure_secrets_store

Azure Secrets Store implementation.

AzureSecretsStore (ServiceConnectorSecretsStore)

Secrets store implementation that uses the Azure Key Vault API.

This secrets store implementation uses the Azure Key Vault API to store secrets. It allows a single Azure Key Vault to be shared with other ZenML deployments as well as other third party users and applications.

Here are some implementation highlights:

  • the name/ID of an Azure secret is derived from the ZenML secret UUID and a zenml prefix in the form zenml-{zenml_secret_uuid}. This clearly identifies a secret as being managed by ZenML in the Azure console.

  • the Secrets Store also uses Azure Key Vault secret tags to store metadata associated with a ZenML secret. The zenml tag in particular is used to identify and group all secrets that belong to the same ZenML deployment.

  • all secret key-values configured in a ZenML secret are stored as a single JSON string value in the Azure Key Vault secret value.

hashicorp_secrets_store

HashiCorp Vault Secrets Store implementation.

HashiCorpVaultSecretsStore (BaseSecretsStore)

Secrets store implementation that uses the HashiCorp Vault API.

This secrets store implementation uses the HashiCorp Vault API to store secrets. It allows a single HashiCorp Vault server to be shared with other ZenML deployments as well as other third party users and applications.

Here are some implementation highlights:

  • the name/ID of an HashiCorp Vault secret is derived from the ZenML secret UUID and a zenml prefix in the form zenml/{zenml_secret_uuid}. This clearly identifies a secret as being managed by ZenML in the HashiCorp Vault server.

  • given that HashiCorp Vault secrets do not support attaching arbitrary metadata in the form of label or tags, we store the entire ZenML secret metadata alongside the secret values in the HashiCorp Vault secret value.

Attributes:

Name Type Description
config

The configuration of the HashiCorp Vault secrets store.

TYPE

The type of the store.

CONFIG_TYPE

The type of the store configuration.

backup_secrets_store Optional[zenml.config.secrets_store_config.SecretsStoreConfiguration]

The configuration of a backup secrets store to use in addition to the primary one as an intermediate step during the migration to a new secrets store.

driver Optional[zenml.zen_stores.sql_zen_store.SQLDatabaseDriver]

The SQL database driver.

database Optional[str]

database name. If not already present on the server, it will be created automatically on first access.

username Optional[str]

The database username.

password Optional[str]

The database password.

ssl_ca Optional[str]

certificate authority certificate. Required for SSL enabled authentication if the CA certificate is not part of the certificates shipped by the operating system.

ssl_cert Optional[str]

client certificate. Required for SSL enabled authentication if client certificates are used.

ssl_key Optional[str]

client certificate private key. Required for SSL enabled if client certificates are used.

ssl_verify_server_cert bool

set to verify the identity of the server against the provided server certificate.

pool_size int

The maximum number of connections to keep in the SQLAlchemy pool.

max_overflow int

The maximum number of connections to allow in the SQLAlchemy pool in addition to the pool_size.

pool_pre_ping bool

Enable emitting a test statement on the SQL connection at the start of each connection pool checkout, to test that the database connection is still viable.

  • the configuration and secrets fields together represent a full valid configuration update, not just a partial update. If either is set (i.e. not None) in the update, their values are merged together and will replace the existing configuration and secrets values.
  • the resource_id field value is also a full replacement value: if set to None, the resource ID is removed from the service connector.
  • the expiration_seconds field value is also a full replacement value: if set to None, the expiration is removed from the service connector.
  • the secret_id field value in the update is ignored, given that secrets are managed internally by the ZenML store.

zen_store_interface

ZenML Store interface.

ZenStoreInterface (ABC)

ZenML store interface.

All ZenML stores must implement the methods in this interface.

The methods in this interface are organized in the following way:

  • they are grouped into categories based on the type of resource that they operate on (e.g. stacks, stack components, etc.)

  • each category has a set of CRUD methods (create, read, update, delete) that operate on the resources in that category. The order of the methods in each category should be:

  • create methods - store a new resource. These methods should fill in generated fields (e.g. UUIDs, creation timestamps) in the resource and return the updated resource.

  • get methods - retrieve a single existing resource identified by a unique key or identifier from the store. These methods should always return a resource and raise an exception if the resource does not exist.
  • list methods - retrieve a list of resources from the store. These methods should accept a set of filter parameters that can be used to filter the list of resources retrieved from the store.
  • update methods - update an existing resource in the store. These methods should expect the updated resource to be correctly identified by its unique key or identifier and raise an exception if the resource does not exist.
  • delete methods - delete an existing resource from the store. These methods should expect the resource to be correctly identified by its unique key or identifier. If the resource does not exist, an exception should be raised.

Best practices for implementing and keeping this interface clean and easy to maintain and extend:

  • keep methods organized by resource type and ordered by CRUD operation
  • for resources with multiple keys, don't implement multiple get or list methods here if the same functionality can be achieved by a single get or list method. Instead, implement them in the BaseZenStore class and have them call the generic get or list method in this interface.
  • keep the logic required to convert between ZenML domain Model classes and internal store representations outside the ZenML domain Model classes
  • methods for resources that have two or more unique keys (e.g. a Workspace is uniquely identified by its name as well as its UUID) should reflect that in the method variants and/or method arguments:
    • methods that take in a resource identifier as argument should accept all variants of the identifier (e.g. workspace_name_or_uuid for methods that get/list/update/delete Workspaces)
    • if a compound key is involved, separate get methods should be implemented (e.g. get_pipeline to get a pipeline by ID and get_pipeline_in_workspace to get a pipeline by its name and the ID of the workspace it belongs to)
  • methods for resources that are scoped as children of other resources (e.g. a Stack is always owned by a Workspace) should reflect the key(s) of the parent resource in the provided methods and method arguments:
    • create methods should take the parent resource UUID(s) as an argument (e.g. create_stack takes in the workspace ID)
    • get methods should be provided to retrieve a resource by the compound key that includes the parent resource key(s)
    • list methods should feature optional filter arguments that reflect the parent resource key(s)

Updates an existing service connector.

The update model contains the fields to be updated. If a field value is set to None in the model, the field is not updated, but there are special rules concerning some fields:

  • the configuration and secrets fields together represent a full valid configuration update, not just a partial update. If either is set (i.e. not None) in the update, their values are merged together and will replace the existing configuration and secrets values.
  • the resource_id field value is also a full replacement value: if set to None, the resource ID is removed from the service connector.
  • the expiration_seconds field value is also a full replacement value: if set to None, the expiration is removed from the service connector.
  • the secret_id field value in the update is ignored, given that secrets are managed internally by the ZenML store.
