• Install releaser:

steps:
  - script: |
    sudo wget https://github.com/quara-dev/releaser/releases/latest/download/releaser.pyz -O /usr/local/bin/releaser
    sudo chmod /usr/local/bin/releaser

• Install releaser with toml optional dependencies to read pyproject.toml files:

steps:
  - script: |
      pip install git+https://github.com/quara-dev/releaser.git toml

• Create a file named manifest.json and publish it as pipeline artefact:

steps:
  - script: python -m releaser create-manifest -o manifest.json
    displayName: Create manifest.json file

  - publish: "$(System.DefaultWorkingDirectory)/manifest.json"
    displayName: Publish manifest.json as pipeline artefact
    artifact: manifest.json

• Define a string variable named MANIFEST holding a manifest:

steps:
  - script: |
      manifest="$(python -m releaser analyze-manifest)"
      echo "##vso[task.setvariable variable=MANIFEST;isoutput=true]$manifest"
    displayName: Create MANIFEST variable holding release manifest as JSON string

  - script: echo $MANIFEST
    displayName: Display MANIFEST variable

The create-manifest command can be used to generate a manifest in JSON format.

• By default, manifest is written to standard output, but -o or --output option can be provided to write manifest to a file:

releaser create-manifest -o manifest.json

• Use the analyze-manifest command to show all or part of a manifest in standard output:

releaser analyze-manifest

This command first generates a manifest by default, but also accept a -i or --input option to read an existing manifest from a file:

releaser analyze-manifest -i manifest.json

Many options are available to query specific information within the manifest.

• It's possible to list all images declared within a manifest:

  releaser analyze-manifest --list-images

• To list images for a single application, use the --app option:

  releaser analyze-manifest --list-images --app myapp

• To list images for a single platform, use the --platform option:

  releaser analyze-manifest --list-images --platform linux/arm64

  Note: Using --platform excludes non-platform images and returns platform images only.

• To list images for all platforms matching a manifest tag, use the --manifest-tag:

  releaser analyze-manifest --list-images --app myapp --manifest-tag "edge"

  Note: Using --manifest-tag excludes non-platform images and returns platform images only.

• Like images, it's possible to list all tags, but the query must always be scoped to an application:

  releaser analyze-manifest --list-tags --app myapp

  Note: This will list all tags, including platform tags.

• To exclude platform tags, use the --no-platform option:

  releaser analyze-manifest --list-tags --app myapp --no-platform

• To list tags for a single platform, use the --platform option:

  releaser analyze-manifest --list-tags --app myapp --platform="linux/arm64"

  Note: Using --platform excludes non-platform tags and returns only plaform tags for any of given platforms only.

• Build all docker images at once using bake-manifest command:

releaser bake-manifest

• Optionally, use --push command to push image to remote registries:

releaser bake-manifest --push

A command can be used to publish manifest using a POST request:

releaser upload-manifest --webhook $AZ_DEVOPS_WEBHOOK_URL
