class snowshu.core.docker.SnowShuDocker

Bases: object

convert_container_to_replica(replica_name: str, active_container: docker.models.containers.Container, passive_container: docker.models.containers.Container) → list[docker.models.images.Image]

coerces a live container into a replica image and returns the image.

replica_name: the name of the new replica

return: [replica_image_from_active,

replica_image_from_passive(skipped if no passive), replica_image_from_local_arch]

create_and_init_container(image: docker.models.images.Image, container_name: str, target_adapter: Type[BaseTargetAdapter], source_adapter: str, network: docker.models.networks.Network, replica_volume: docker.models.volumes.Volume, envars: dict) → docker.models.containers.Container

Method used during self.startup() execution, creates, starts and setups container

input: some stuff needed to define a container launch return: container object instance, in a running state and already set up

find_snowshu_images() → List[docker.models.images.Image]

get_adapter_name(name: str) → str

get_docker_image_attributes(image: str) → Dict

Retrieve image-related attributes

remove_container(container: str) → None

static replica_image_name_to_common_name(name: str) → str

reverse the replica sanitizer.

static sanitize_replica_name(name: str) → str

Much more strict than standard docker tag names.

ReplicaFactory names are coerced into ASCII lowercase, dash- seperated a-z0-9 strings when possible.

startup(target_adapter: Type['BaseTargetAdapter'], source_adapter: str, arch_list: list[str], envars: list) -> tuple(docker.models.containers.Container)
