Synopsis

• Provide one or more image names, and the module will inspect each, returning an array of inspection results.
• If an image does not exist locally, it will not appear in the results. If you want to check whether an image exists locally, you can call the module with the image name, then check whether the result list is empty (image does not exist) or has one element (the image exists locally).
• The module will not attempt to pull images from registries. Use docker_image with source set to pull to ensure an image is pulled.

Requirements

The below requirements are needed on the host that executes this module.

• Docker API >= 1.20
• Docker SDK for Python: Please note that the docker-py Python module has been superseded by docker (see here for details). For Python 2.6, docker-py must be used. Otherwise, it is recommended to install the docker Python module. Note that both modules should not be installed at the same time. Also note that when both modules are installed and one of them is uninstalled, the other might no longer function and a reinstall of it is required.
• Docker SDK for Python >= 1.8.0 (use docker-py for Python 2.6)
