mlrun.db

class mlrun.db.httpdb.HTTPRunDB(base_url, user='', password='', token='')[source]

Bases: mlrun.db.base.RunDBInterface

Interface for accessing and manipulating the mlrun persistent store, maintaining the full state and catalog of objects that MLRun uses. The HTTPRunDB class serves as a client-side proxy to the MLRun API service which maintains the actual data-store, accesses the server through REST APIs.

The class provides functions for accessing and modifying the various objects that are used by MLRun in its operation. The functions provided follow some standard guidelines, which are:

  • Every object in MLRun exists in the context of a project (except projects themselves). When referencing an object through any API, a project name must be provided. The default for most APIs is for an empty project name, which will be replaced by the name of the default project (usually default). Therefore, if performing an API to list functions, for example, and not providing a project name - the result will not be functions from all projects but rather from the default project.

  • Many objects can be assigned labels, and listed/queried by label. The label parameter for query APIs allows for listing objects that:

    • Have a specific label, by asking for label="<label_name>". In this case the actual value of the label doesn’t matter and every object with that label will be returned

    • Have a label with a specific value. This is done by specifying label="<label_name>=<label_value>". In this case only objects whose label matches the value will be returned

  • Most objects have a create method as well as a store method. Create can only be called when such an does not exist yet, while store allows for either creating a new object or overwriting an existing object.

  • Some objects have a versioned option, in which case overwriting the same object with a different version of it does not delete the previous version, but rather creates a new version of the object and keeps both versions. Versioned objects usually have a uid property which is based on their content and allows to reference a specific version of an object (other than tagging objects, which also allows for easy referencing).

  • Many objects have both a store function and a patch function. These are used in the same way as the corresponding REST verbs - a store is passed a full object and will basically perform a PUT operation, replacing the full object (if it exists) while patch receives just a dictionary containing the differences to be applied to the object, and will merge those changes to the existing object. The patch operation also has a strategy assigned to it which determines how the merge logic should behave. The strategy can be either replace or additive. For further details on those strategies, refer to https://pypi.org/project/mergedeep/

abort_run(uid, project='', iter=0)[source]

Abort a running run - will remove the run’s runtime resources and mark its state as aborted

api_call(method, path, error=None, params=None, body=None, json=None, headers=None, timeout=45)[source]

Perform a direct REST API call on the mlrun API server.

Caution

For advanced usage - prefer using the various APIs exposed through this class, rather than directly invoking REST calls.

Parameters
  • method – REST method (POST, GET, PUT…)

  • path – Path to endpoint executed, for example "projects"

  • error – Error to return if API invocation fails

  • body – Payload to be passed in the call. If using JSON objects, prefer using the json param

  • json – JSON payload to be passed in the call

  • headers – REST headers, passed as a dictionary: {"<header-name>": "<header-value>"}

  • timeout – API call timeout

Returns

Python HTTP response object

connect(secrets=None)[source]

Connect to the MLRun API server. Must be called prior to executing any other method. The code utilizes the URL for the API server from the configuration - mlconf.dbpath.

For example:

mlconf.dbpath = mlconf.dbpath or 'http://mlrun-api:8080'
db = get_run_db().connect()
create_feature_set(feature_set: Union[dict, mlrun.api.schemas.feature_store.FeatureSet], project='', versioned=True)dict[source]

Create a new FeatureSet and save in the mlrun DB. The feature-set must not previously exist in the DB.

Parameters
  • feature_set – The new FeatureSet to create.

  • project – Name of project this feature-set belongs to.

  • versioned – Whether to maintain versions for this feature-set. All versions of a versioned object will be kept in the DB and can be retrieved until explicitly deleted.

Returns

The FeatureSet object (as dict).

create_feature_vector(feature_vector: Union[dict, mlrun.api.schemas.feature_store.FeatureVector], project='', versioned=True)dict[source]

Create a new FeatureVector and save in the mlrun DB.

Parameters
  • feature_vector – The new FeatureVector to create.

  • project – Name of project this feature-vector belongs to.

  • versioned – Whether to maintain versions for this feature-vector. All versions of a versioned object will be kept in the DB and can be retrieved until explicitly deleted.

Returns

The FeatureVector object (as dict).

create_marketplace_source(source: Union[dict, mlrun.api.schemas.marketplace.IndexedMarketplaceSource])[source]

Add a new marketplace source.

MLRun maintains an ordered list of marketplace sources (“sources”). Each source has its details registered and its order within the list. When creating a new source, the special order -1 can be used to mark this source as last in the list. However, once the source is in the MLRun list, its order will always be >0.

The global marketplace source always exists in the list, and is always the last source (order = -1). It cannot be modified nor can it be moved to another order in the list.

The source object may contain credentials which are needed to access the datastore where the source is stored. These credentials are not kept in the MLRun DB, but are stored inside a kubernetes secret object maintained by MLRun. They are not returned through any API from MLRun.

Example:

import mlrun.api.schemas

# Add a private source as the last one (will be #1 in the list)
private_source = mlrun.api.schemas.IndexedMarketplaceSource(
    order=-1,
    source=mlrun.api.schemas.MarketplaceSource(
        metadata=mlrun.api.schemas.MarketplaceObjectMetadata(name="priv", description="a private source"),
        spec=mlrun.api.schemas.MarketplaceSourceSpec(path="/local/path/to/source", channel="development")
    )
)
db.create_marketplace_source(private_source)

# Add another source as 1st in the list - will push previous one to be #2
another_source = mlrun.api.schemas.IndexedMarketplaceSource(
    order=1,
    source=mlrun.api.schemas.MarketplaceSource(
        metadata=mlrun.api.schemas.MarketplaceObjectMetadata(name="priv-2", description="another source"),
        spec=mlrun.api.schemas.MarketplaceSourceSpec(
            path="/local/path/to/source/2",
            channel="development",
            credentials={...}
        )
    )
)
db.create_marketplace_source(another_source)

Returns

The source object as inserted into the database, with credentials stripped.

create_project_secrets(project: str, provider: Union[str, mlrun.api.schemas.secret.SecretProviderName] = <SecretProviderName.vault: 'vault'>, secrets: Optional[dict] = None)[source]

Create project-context secrets using either vault or kubernetes provider. When using with Vault, this will create needed Vault structures for storing secrets in project-context, and store a set of secret values. The method generates Kubernetes service-account and the Vault authentication structures that are required for function Pods to authenticate with Vault and be able to extract secret values passed as part of their context.

Note

This method used with Vault is currently in technical preview, and requires a HashiCorp Vault infrastructure properly set up and connected to the MLRun API server.

When used with Kubernetes, this will make sure that the project-specific k8s secret is created, and will populate it with the secrets provided, replacing their values if they exist.

Parameters
  • project – The project context for which to generate the infra and store secrets.

  • provider – The name of the secrets-provider to work with. Accepts a SecretProviderName enum.

  • secrets

    A set of secret values to store. Example:

    secrets = {'password': 'myPassw0rd', 'aws_key': '111222333'}
    db.create_project_secrets(
        "project1",
        provider=mlrun.api.schemas.SecretProviderName.vault,
        secrets=secrets
    )
    

create_schedule(project: str, schedule: mlrun.api.schemas.schedule.ScheduleInput)[source]

Create a new schedule on the given project. The details on the actual object to schedule as well as the schedule itself are within the schedule object provided. The ScheduleCronTrigger follows the guidelines in https://apscheduler.readthedocs.io/en/v3.6.3/modules/triggers/cron.html. It also supports a from_crontab() function that accepts a crontab-formatted string (see https://en.wikipedia.org/wiki/Cron for more information on the format).

Example:

from mlrun.api import schemas

# Execute the get_data_func function every Tuesday at 15:30
schedule = schemas.ScheduleInput(
    name="run_func_on_tuesdays",
    kind="job",
    scheduled_object=get_data_func,
    cron_trigger=schemas.ScheduleCronTrigger(day_of_week='tue', hour=15, minute=30),
)
db.create_schedule(project_name, schedule)
