Publish Artifacts

This step allows you to publish artifacts for different languages to different targets:

You can publish Python wheels to cloud storage, or to PyPi.
You can publish Scala jars to cloud storage, or to Ivy

There's an implicit dependency on [building artifacts](build-artifact) when publishing to PyPi and cloud storage

Regarding Scala, only SBT is supported as build tool

Deployment

Add the following task to deployment.yaml

field	description	values
`task`	`"publish_artifact"`
`language`	The language identifier of your project	One of `python`, `scala`
`target`	List of targets to push the artifact to. For Python these can be: `cloud_storage`, `pypi`. For Scala artifacts these can be: `cloud_storage`, `ivy`
`python_file_path` [optional]	The path relative to the root of your project to the python script that serves as entrypoint for a databricks job

For all languages, the assumption is that the artifact has already been built, for example by the build_artifact step that Takeoff offers.

You can specify a main file (for Databricks jobs) by using the python_file_path key. The path should be relative from the root of your project.

Takeoff config

Publish to Azure Storage Account V1

Credentials for the Azure Storage Account V1 must be available in your cloud vault when pushing to Azure cloud_storage. Make sure .takeoff/config.yaml contains the following keys:

azure:
  keyvault_keys:
    storage_account:
      account_name: "azure-shared-blob-username"
      account_key: "azure-shared-blob-password"
  common:
      artifacts_shared_storage_account_container_name: libraries

For Scala, Takeoff assumes an assembly jar has been built.

Publish to PyPi

Credentials for PyPi (username, password) must be available in your cloud vault when pushing to any PyPi artifact store. Make sure takeoff_config.yaml contains the following azure_keyvault_keys:

azure:
  keyvault_keys:
    artifact_store:
      repository_url: "artifact-store-upload-url"
      username: "artifact-store-username"
      password: "artifact-store-password"

Publish to Ivy

Credentials for your Ivy repository must be available as enviroment variables and your SBT project must be configured to read these and handle the sbt publish command.

Examples

Minimum configuration example for Python. This pushes a Python wheel to PyPi.

steps:
- task: publish_artifact
  language: python
  target:
    - pypi

Extended configuration example for Scala. This pushes a jar to both cloud storage and your ivy repository

- task: publish_artifact
  language: scala
  target:
    - cloud_storage
    - ivy
