Jina Hub Builder

Jina’s hub-builder is a simple interface for building & validating Jina Hub Executors. It is built on top of Jina Hub interface. It can be used as a GitHub action in the CI/CD workflow, or via CLI.

Github action usage:

You can use the hub builder as a part of the CICD pipeline, to build and test images in the Pull Request. The following YAML can be directly used in the workflow .github/workflows/hub-builder.yml.

name: Hub Builder

on: [pull_request]

    runs-on: ubuntu-latest
      - name: Checkout
        uses: actions/[email protected]
      - name: Jina Hub Image Builder
        uses: jina-ai/[email protected]
        jina_hub_token: ${{ secrets.JINA_HUB_TOKEN }}

On every new PR, the builder finds modifications in manifest.yml recursively and tries to build a Hub image using the latest files. That means, when you update an image, you must change manifest.yml to trigger the build, i.e. you can simply bump the version field in manifest.yml. This is done one by one for each modified Executor.

Hub builder action accepts the following parameters:

Parameter Type Required Description
push boolean yes true if you want to upload to Docker Hub & make it available for everyone's use (usually in CD)
false during tests run (usually in CI)
jina_hub_token string yes Personal Access Token for your GitHub user
dockerhub_username string no Username for Docker Hub
(Ignore if you want us to host your pod in Jina's repository)
dockerhub_password string no Password for Docker Hub
(Ignore if you want us to host your pod in Jina's repository)
dockerhub_registry string no Docker Hub Registry
(Ignore if you want us to host your pod in Jina's repository)
slack_webhook string no Slack webhook if you want custom notifications
jina_version string no version of Jina for building Hub image

For authorization, you’d need to create a Personal Access Token in your github settings & pass the same. e.g., jina_hub_token: ${{ secrets.JINA_HUB_TOKEN }}

The input argument jina_version can be different from the version of Jina for running the Pod in the container. The latter should be set in your _jina_pod/requirements.txt. The jina_version is the version of Jina when building the Pod image.

Output of the Action

There are two outputs you can use in the post-action:

  1. success_targets: Successfully built targets with their paths

  2. failed_targets: Failed built targets with their paths
