Encapsulates platform-specific configuration such as access credentials or AWS endpoints. Config is provided as an argument to the Model and is used to instantiate concrete implementations of lower-level components based on its properties so that users work with a configuration-based API when it comes to fine-tuning the workloads.

Arguments:

  • docker_config_provider: the configuration provider for Docker registry.
  • storage_config_provider: the configuration provider for blob storage access. Currently, only S3 and MinIO are supported.
  • docker_registry_url: private custom Docker registry URL to use with provided TLS certificates.
  • docker_registry_certificate_provider: the configuration provider for Docker registry certificate.
  • base_dir: base directory to use for referencing relative file paths of model files. Defaults to current working directory.
  • base_model_storage_uri: name of a bucket in the remote storage (MinIO or S3) to store the model. Defaults to ‘s3://kaptain/models’

A representation of a machine learning model.

When the model is created for the first time, its internal revision is set to a random UUID and its internal state is “untrained”. Once the model is trained or tuned, its state will be updated accordingly, hyperparameter values set, its revision refreshed, and it can be saved or deployed. Each action (train, tune, deploy) alters the revision and is stored in the model tracking database.

Arguments:

Details on the format can be found here: https://pip.pypa.io/en/stable/cli/pip_install/requirements-file-format.

  • id: Unique identifier of model, e.g. “dev/mnist”. It is recommended to include the stage of the model (e.g. dev/prod) in the name to make it easier to filter models under active development and in production.
  • name: Short name of the model, e.g. “MNIST”. This name is visible in the model tracking database.
  • description: Description of the model, e.g. “Digit recognition for MNIST data set”. This description is visible in the model tracking database.
  • version: Model version, e.g. “4.5”
  • main_file: Main (Python) file that contains the executable model code, e.g. “trainer.py”.
  • image_name: Name of the repository to push the resulting image, e.g. ‘kaptain/mnist’ Can also contain image tag, e.g. “kaptain/mnist:0.0.1-tensorflow-2.2.0”.
  • extra_files: Auxiliary files, e.g. [“utils.py”, “data_loader.py”].
  • requirements: Path to the file with additional python packages to install into the image in pip compatible format (e.g. “requirements.txt”).
  • framework: Machine learning library or framework used for the model, e.g. “tensorflow”.
  • framework_version: Machine learning library or framework version used by model, e.g. “2.3.2”
  • base_image: Base container image, e.g. “tensorflow-2.3.2”

deploy_canary

 | deploy_canary(canary_traffic_percentage: int, model_uri: Optional[str] = None, **kwargs: str, ,) -> None

Deploys a model in a canary with a pre-determined percentage of traffic. A canary deployment allows a model to be run in parallel with a baseline or previous model revision. This allows traffic to be split, so the latest revision can be checked for possible issues with model (e.g. compared to the baseline) or system (e.g. latency) performance. To deploy a model to the canary, a previously deployed model revision must exist.

To deploy canary with 30 percent traffic:

model.deploy_canary(canary_traffic_percentage=30)

To change the canary traffic percentage to 50 (half the traffic):

model.deploy_canary(canary_traffic_percentage=50)

To deploy canary with 30 percent traffic and specified saved model location:

model.deploy_canary(canary_traffic_percentage=30, model_uri=uri)

To change the canary traffic percentage to 50 (half the traffic) for a model deployed from a specified saved location:

model.deploy_canary(canary_traffic_percentage=50, model_uri=uri)

Arguments:

  • canary_traffic_percentage: the percentage of traffic to route to the canary model.
  • model_uri: URI of the saved model to be loaded. If None, the default location managed by Kaptain is chosen based on the most recent state of the model.

Docker Registry Certificate Provider is a container for private Docker registries running with custom/self-signed TLS certificates which are required for pushing Docker images containing model training code.

Docker Registry Certificate Provider by default loads the configuration from $HOME/.tls/certificate.crt. It is also possible to specify a custom registry certificate.crt location using DockerRegistryCertificateProvider.from_file(path=/path/to/certificate.crt).

Docker Registry certificate.crt file can be created ad-hoc while using a notebook or mounted to the notebook from a Secret. To support mounting of a shared Docker certificate.crt as a volume, the system administrator must create the PodDefault resource with a certificate file to make it available for the user.

Arguments:

  • certificate_body: The configuration string in json format
  • certificate_path: Path to the certificate file (optional)

kaptain.platform.config.docker

DockerConfigurationProvider Objects

class DockerConfigurationProvider(FileBasedConfigurationProvider)

__init__

 | __init__(config_json: str)

Docker Configuration Provider is a container for user Docker configuration which are required for pulling and pushing images used in training and tuning jobs.

Docker Configuration Provider supports standard Docker config.json file of the following format:

    {
        "auths": {
                "https://index.docker.io/v1/": {
                        "auth": "<username and password in base64>"
                }
        }
    }

The auth field is a base64-encoded string of the form “:” where and are the actual username and password used to login to Docker registry. To generate value for auth field, use the following command: echo -n "<username>:<password>" | base64.

Docker Configuration Provider by default loads the configuration from $HOME/.docker/config.json. It is also possible to specify a custom config.json location using DockerConfigurationProvider.from_file(path=/path/to/config.json).

Docker config.json file can be created ad-hoc while using a notebook or mounted to the notebook from a Secret. To support mounting of a shared Docker config.json as a volume, the system administrator must create the PodDefault resource with a pre-populated file to make it available for the user.

Arguments:

  • config_json: The configuration string in json format

  • region_name: The name of AWS region.
  • s3_endpoint: The complete URL of S3 endpoint. This parameter is required when working with non-standard, S3-compatible storage solutions such as MinIO. It should be set to a resolvable address of the running server.
  • s3_signature_version: The signature version when signing requests
  • s3_force_path_style: When enabled, the clients will use path style instead of URL style for accessing buckets

get_secret_body

 | get_secret_body() -> Dict[str, str]
