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 Ansible 2.12 on.
- name: pull an image docker_image: name: pacur/centos-7 source: pull
- name: Tag and push to docker hub docker_image: name: pacur/centos-7:56 repository: dcoppenhagan/myimage:7.56 push: yes source: local
- name: Tag and push to local registry docker_image: # Image will be centos:7 name: centos # Will be pushed to localhost:5000/centos:7 repository: localhost:5000/centos tag: 7 push: yes source: local
- name: Add tag latest to image docker_image: name: myimage:7.1.2 repository: myimage:latest # As 'latest' usually already is present, we need to enable overwriting of existing tags: force_tag: yes source: local
- name: Remove image docker_image: state: absent name: registry.ansible.com/chouseknecht/sinatra tag: v1
- name: Build an image and push it to a private repo docker_image: build: path: ./sinatra name: registry.ansible.com/chouseknecht/sinatra tag: v1 push: yes source: build

- name: Build image and with build args docker_image: name: myimage build: path: /path/to/build/dir args: log_volume: /var/log/myapp listen_port: 8080 source: build
- name: Build image using cache source docker_image: name: myimage:latest build: path: /path/to/build/dir # Use as cache source for building myimage cache_from: - nginx:latest - alpine:3.8 source: build
rm: default: true description: - Remove intermediate containers after build. - Please use I(build.rm) instead. This option will be removed in Ansible 2.12. type: bool tag: default: latest description: - Used to select an image when pulling. Will be added to the image when pushing, tagging or building. Defaults to I(latest). - If I(name) parameter format is I(name:tag), then tag value from I(name) will take precedence. type: str tls: default: false description: - Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server. Note that if I(validate_certs) is set to C(yes) as well, it will take precedence. - If the value is not specified in the task, the value of environment variable C(DOCKER_TLS) will be used instead. If the environment variable is not set, the default value will be used. type: bool name: description: - 'Image name. Name format will be one of: name, repository/name, registry_server:port/name. When pushing or pulling an image the name can optionally include the tag by appending '':tag_name''.' - Note that image IDs (hashes) are not supported. required: true type: str path: aliases: - build_path description: - Use with state 'present' to build an image. Will be the path to a directory containing the context and Dockerfile for building an image. - Set I(source) to C(build) if you want to build the image. The option will be set automatically before Ansible 2.12 if this option is used. From Ansible 2.12 on, you have to set I(source) to C(build). - Please use I(build.path) instead. This option will be removed in Ansible 2.12. type: path pull: description: - When building an image downloads any updates to the FROM image in Dockerfile. - Please use I(build.pull) instead. This option will be removed in Ansible 2.12. - The default is currently C(yes). This will change to C(no) in Ansible 2.12. type: bool push: default: false description: - Push the image to the registry. Specify the registry as part of the I(name) or I(repository) parameter. type: bool build: description: - Specifies options used for building images. suboptions: args: description: - Provide a dictionary of C(key:value) build arguments that map to Dockerfile ARG directive. - Docker expects the value to be a string. For convenience any non-string values will be converted to strings. - Requires Docker API >= 1.21. type: dict cache_from: description: - List of image names to consider as cache source. elements: str type: list container_limits: description: - A dictionary of limits applied to each container created by the build process. suboptions: cpusetcpus: description: - CPUs in which to allow execution, e.g., "0-3", "0,1". type: str cpushares: description: - CPU shares (relative weight). type: int memory: description: - Set memory limit for build. type: int memswap: description: - Total memory (memory + swap), -1 to disable swap. type: int type: dict dockerfile: description: - Use with state C(present) and source C(build) to provide an alternate name for the Dockerfile to use when building an image. - This can also include a relative path (relative to I(path)). type: str etc_hosts: description: - Extra hosts to add to C(/etc/hosts) in building containers, as a mapping of hostname to IP address. type: dict http_timeout: description: - Timeout for HTTP requests during the image build operation.

Use with state C(present) to build, load or pull an image when the image already exists. Also use with state C(present) to force tagging an image. - Please stop using this option, and use the more specialized force options I(force_source), I(force_absent) and I(force_tag) instead. - This option will be removed in Ansible 2.12. type: bool 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 Ansible 2.12, 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. - '*Note:* C(state=build) is DEPRECATED and will be removed in Ansible 2.11.
