Default variable details¶
debops.docker_registry default variables have more extensive
configuration than simple strings or lists, here you can find documentation and
examples for them.
docker_registry__*_config variables contain configuration for the
Docker Registry service. The Docker Registry uses a YAML configuration file
with multiple level of configuration keys. To allow for better control over the
configuration file contents, the role uses a list of YAML dictionaries with
named entries which are recursively merged during configuration file
Switch the Docker Registry to an Amazon Simple Storage Service (S3) backend, based on the example configuration:
docker_registry__config: # Disable default local filesystem storage - name: 'default-storage' state: 'absent' - name: 'storage-s3' config: storage: s3: region: 'us-east-1' bucket: 'registry.example.org' middleware: storage: - name: 'cloudfront' options: baseurl: 'https://example.cloudfront.net/' privatekey: '/etc/docker/cloudfront/pk-example.pem' keypairid: 'example'
Each entry in the list is a YAML dictionary with specific parameters:
- Required. An identifier of this configuration entry, not used otherwise. Configuration entries with the same identifier are merged together, entries later on the list can affect the earlier ones.
- Required. An YAML dictionary with Docker Registry configuration options. Each
configdictionary will be merged recursively in the final configuration file. You have to specify the entire dictionary structure from the "base" of the configuration file. Refer to the Docker Registry documentation for details about supported parameters and their values.
- Optional. If not specified or
present, a given configuration entry will be included in the final configuration file. If
absent, the entry will not be included in the final configuration file - this can be used to disable configuration entries with specific identifiers. If
ignore, a given configuration entry will not be evaluated by the role.
