Databricks asset bundles deployment to development

[naga_databricks]

Hi All,

I am using Databricks Asset Bundles to deploy my code on github to databricks workspace. I have written out the Github Action as provided on databricks documentation.

I have setup the personal access token for the service principal I want to use to deploy with a Github Action.

I have can_user & can_manage permisions on this service principal.

I generated a personal access token for a service principal following the steps from https://docs.gcp.databricks.com/dev-tools/service-principals.html

Following which I have setup the Github Action following https://docs.gcp.databricks.com/dev-tools/bundles/ci-cd.html

I have the SP_TOKEN setup on the github secrets for the respective environments.

When I deploy from my local using my user personal access token, I can see the development mode deployment working very well.

However, on using my user personal token or the personal token of service principal from Github Actions, I get following error:

Error: default auth: cannot configure default credentials. Config: host=

Following is the Github Actions:

# This workflow validates, deploys, and runs the specified bundle
# within a pre-production target named "qal".
name: "DAB - Non Production deployment"

# Ensure that only a single job or workflow using the same concurrency group
# runs at a time.
concurrency: "1"

## Trigger this workflow whenever a pull request is opened against the repo's
## main branch or an existing pull request's head branch is updated.

      Environment:
        type: choice
        description: 'Choose the environment:'
        required: true
        options:
          - dev
          - qal


jobs:
  deploy:
    name: "Deploy bundle"
    runs-on: ubuntu-latest

    steps:
      # Check out this repo, so that this workflow can access it.
      - uses: actions/checkout@v3

      # Download the Databricks CLI.
      # See https://github.com/databricks/setup-cli
      - uses: databricks/setup-cli@main


      # Validate the bundle to the selected target as defined
      # in the bundle's settings file.
      - run: databricks bundle validate
        working-directory: .
        env:
          DATABRICKS_TOKEN: ${{ secrets.SP_TOKEN }}
          DATABRICKS_BUNDLE_ENV: ${{github.event.inputs.Environment}}


      # Deploy the bundle to the selected target as defined
      # in the bundle's settings file.
      - run: databricks bundle deploy
        working-directory: .
        env:
          DATABRICKS_TOKEN: ${{ secrets.SP_TOKEN }}
          DATABRICKS_BUNDLE_ENV: ${{github.event.inputs.Environment}}

Can someone who have setup the Github Actions with DAB help me out

Finally, i was able to identify the missing piece. This was setting up the environment identifier for the runner. 

    name: "Deploy bundle"
    runs-on: ubuntu-latest
    environment: ${{github.event.inputs.Environment}}

With this, the action was able to get the secrets from the github environment. 

The host property for DATABRICKS_HOST is provided via the bundles configurations, it doesnt need to be provided again on the Github action.
