Example:

# Run a container from the image "myimage"
docker run -it myimage

# Start a container named "mycontainer"
docker start mycontainer

# Stop a container named "mycontainer"
docker stop mycontainer

# Remove a container named "mycontainer"
docker rm mycontainer

# Remove an image named "myimage"
docker rmi myimage

# List all running containers
docker ps

# Build an image from the Dockerfile in the current directory
docker build -t myimage .

# Pull an image named "myimage" from the "myregistry" registry
docker pull myregistry/myimage

# Push an image named "myimage" to the "myregistry" registry
docker push myregistry/myimage

Note: (Almost) Always use --rm option while running the container to remove the container automatically when it exits.
