Solution:

This cheat sheet.  😆 

All commands below are called as options to the base docker command. Run docker --help for more information on a particular command.

app*	Docker Application
assemble*	Framework-aware builds (Docker Enterprise)
builder	Manage builds
cluster	Manage Docker clusters (Docker Enterprise)
config	Manage Docker configs
context	Manage contexts
engine	Manage the docker Engine
image	Manage images
network	Manage networks
node	Manage Swarm nodes
plugin	Manage plugins
registry*	Manage Docker registries
secret	Manage Docker secrets
service	Manage services
stack	Manage Docker stacks
swarm	Manage swarm
system	Manage Docker
template*	Quickly scaffold services (Docker Enterprise)
trust	Manage trust on Docker images
volume	Manage volumes

Build

Build an image from the Dockerfile in the
current directory and tag the image:

docker build -t myimage:1.0 .

List all images that are locally stored with
the Docker Engine

docker image ls

Delete an image from the local image store
docker image rm alpine:3.4

Share

Pull an image from a registry
docker pull myimage:1.0

Retag a local image with a new image name and tag
docker tag myimage:1.0 myrepo/ myimage:2.0

Push an image to a registry
docker push myrepo/myimage:2.0

Run

Run a container from the Alpine version 3.9 image, name the running container “web” and expose port 5000 externally, mapped to port 80 inside the container.
docker container run --name web -p 5000:80 alpine:3.9

Stop a running container through SIGTERM
docker container stop web

Stop a running container through SIGKILL
docker container kill web

List the networks
docker network ls

List the running containers (add –all to include stopped containers)
docker container ls

Delete all running and stopped containers
docker container rm -f $(docker ps -aq)

Print the last 100 lines of a container’s logs docker container
logs --tail 100 web

Conclusion:

This is the way to do it.
