Install collection

Install with ansible-galaxy collection install community.general:==1.3.14


Add to requirements.yml

  collections:
    - name: community.general
      version: 1.3.14

Description

Build, load or pull an image, making the image available for creating containers. Also supports tagging an image into a repository and archiving an image to a .tar file.

Since Ansible 2.8, it is recommended to explicitly specify the image's source (I(source) can be C(build), C(load), C(pull) or C(local)). This will be required from community.general 2.0.0 on.

state:
    choices:
    - absent
    - present
    - build
    default: present
    description:
    - Make assertions about the state of an image.
    - When C(absent) an image will be removed. Use the force option to un-tag and remove
      all images matching the provided name.
    - When C(present) check if an image exists using the provided name and tag. If the
      image is not found or the force option is used, the image will either be pulled,
      built or loaded, depending on the I(source) option.
    - By default the image will be pulled from Docker Hub, or the registry specified in
      the image's name. Note that this will change in community.general 2.0.0, so to make
      sure that you are pulling, set I(source) to C(pull). To build the image, provide
      a I(path) value set to a directory containing a context and Dockerfile, and set
      I(source) to C(build). To load an image, specify I(load_path) to provide a path
      to an archive file. To tag an image to a repository, provide a I(repository) path.
      If the name contains a repository path, it will be pushed.

      when this value is used.
    - Use C(pull) to pull the image from a registry.
    - Use C(local) to make sure that the image is already available on the local docker
      daemon, i.e. do not try to build, pull or load the image.
    - Before community.general 2.0.0, the value of this option will be auto-detected to
      be backwards compatible, but a warning will be issued if it is not explicitly specified.
      From community.general 2.0.0 on, auto-detection will be disabled and this option
