docker version	Show the Docker version information
docker volume	Manage volumes
docker wait	Block until one or more containers stop, then print their exit codes

 Let talk about the run command:

Docker runs processes in isolated containers. A container is a process which runs on a host. The host may be local or remote. When an operator executes docker run, the container process that runs is isolated in that it has its own file system, its own networking, and its own isolated process tree separate from the host.

The basic docker run command takes this form:

$docker run [OPTIONS] IMAGE[:TAG|DIGEST] [COMMAND] [ARG...]

The docker run command must specify an IMAGE to derive the container from.An image developer can define image defaults related to:

• detached or foreground running
• container identification
• network settings
• runtime constraints on CPU and memory

Operator exclusive options

• Detached vs foreground
• Container identification
• IPC settings
• Network settings
• Restart policies
• Clean up
• Runtime constraint on resources
• Runtime privilege and Linux capabilities

Use the Docker command line

To list available commands, either run docker with no parameters or execute docker help:

$docker

Usage: docker [OPTIONS] COMMAND [ARG...]

            docker [ --help | -v | --version]

Options:

     --config string      Location of client config files (default "/root/.docker")
  -D, --debug              Enable debug mode
      --help               Print usage
  -H, --host value         Daemon socket(s) to connect to (default [])
  -l, --log-level string   Set the logging level ("debug", "info", "warn", "error", "fatal") (default "info")
      --tls                Use TLS; implied by --tlsverify
      --tlscacert string   Trust certs signed only by this CA (default "/root/.docker/ca.pem")
      --tlscert string     Path to TLS certificate file (default "/root/.docker/cert.pem")
      --tlskey string      Path to TLS key file (default "/root/.docker/key.pem")
      --tlsverify          Use TLS and verify the remote
  -v, --version            Print version information and quit

Description:

Environment variables

For your reference, sharing you the list of environment variables are supported by the docker command line:

• DOCKER_API_VERSION The API version to use (e.g. 1.19)
• DOCKER_CONFIG The location of your client configuration files.
• DOCKER_CERT_PATH The location of your authentication keys.
• DOCKER_DRIVER The graph driver to use.
• DOCKER_HOST Daemon socket to connect to.
• DOCKER_NOWARN_KERNEL_VERSION Prevent warnings that your Linux kernel is unsuitable for Docker.
• DOCKER_RAMDISK If set this will disable ‘pivot_root’.
• DOCKER_TLS_VERIFY When set Docker uses TLS and verifies the remote.
• DOCKER_CONTENT_TRUST When set Docker uses the notary to sign and verify images. Equates to --disable-content-trust=false for the build, create, pull, push, run.
• DOCKER_CONTENT_TRUST_SERVER The URL of the Notary server to use. This defaults to the same URL as the registry.
• DOCKER_HIDE_LEGACY_COMMANDS When set, Docker hides “legacy” top-level commands (such as docker rm, and docker pull) in docker help output, and only Management commands per-object-type (e.g., docker container) are printed. This may become the default in a future release, at which point this environment variable is removed.
• DOCKER_TMPDIR Location for temporary Docker files.

Because Docker is developed using Go, you can also use any environment variables used by the Go runtime. In particular, you may find these useful:

• HTTP_PROXY
• HTTPS_PROXY
• NO_PROXY

This is all about the commands. So open the docker terminal and enjoy them
