Ansible-bender now uses Azure Pipelines as a CI system.

Features

• There were updates to documentation in README:
  • Info about vfs and overlay buildah storage backends.
  • Rootless containers.
  • How you can use base images with python2.
  • Requirements of ansible-bender.
• Bender now produces a more clear message when a base image doesn't have a
  python interpreter.
• You are now able to pass path to the python interpreter inside the base image
  via CLI.

Bug fixes

• Bender now uses more buildah commands instead of podman.
• If bender is invoked with a non-root user, the ansible-playbook session is
  now wrapped with buildah unshare.
• Don't print to error log when an image is being pulled.
