The gcr.io/cloud-builders/twine image is maintained by the Cloud Build team, but it may not support the most recent features or versions of Twine. We also do not provide historical pinned versions of Twine.

While there is, as of this writing, no official Twine image, users may install Twine from a Python image. The Python team provides python images that support multiple tagged versions of Python on multiple platforms. Please visit https://hub.docker.com/_/python for more details. The following example illustrates usage of an official python image.

steps:
- name: 'python:slim'
  entrypoint: '/bin/sh'
  args:
    - -c
    - |
      python -m pip install --user twine keyrings.google-artifactregistry-auth
- name: 'python:slim'
  entrypoint: '/bin/sh'
  args:
    - -c
    - |
      python -m twine upload --verbose --repository-url 'https://my-region-python.pkg.dev/my-project/my-repo' dist/*
