Package docker provides the "docker" command.

Package main is a cli tool that automates managing image digests by tracking them in a separate Lockfile (think package-lock.json or Pipfile.lock) - with docker-lock, you can refer to images in Dockerfiles, docker-compose files, and Kubernetes manifests by mutable tags (as in python:3.6) yet receive the same benefits as if you had specified immutable digests (as in python:3.6@sha256:25a189a536ae4d...).

Package generate provides the "generate" command.

Package lock provides the "lock" command.

Package rewrite provides the "rewrite" command.

Package verify provides the "verify" command.

Package version provides the "version" command.
