# Build an image
docker build -t <image_name> <dockerfile_path>

# Run a container
docker run -d -p <host_port>:<container_port> --name <container_name> <image_name>
PS1: In this sample, I'm mapping ports with option '-p'. For more details, see below.
PS2: You can add links among containers using --link <container_name>:<alias> option.

# Start a bash session at a running container
docker exec -it <nome_container> bash

# See container's log
docker logs <nome_container>

docker ps -a

# Remove a container
docker rm -f <nome_container>

# Remove ALL containers
docker rm -f $(docker ps -a -q)

# Remove an image
docker rmi -f <nome_imagem>

# Remove dangling images (Dangling images", images without tag)
docker rmi $(docker images -q -f dangling=true)

# Copy a file from container to host
docker cp <nome_container>:/caminho/no/container /caminho/no/host
Exemplo: docker cp app1:/home/ec2-user/log.txt /logs

# Docker stats
