Basics

Create a container with an interactive shell: docker run -t fedora -i /bin/bash

# make changes (install a server)

commit using docker commit <container id>

# run a server program and expose

# host: 9090, container: 90

docker run -d -p 9090:80 random/apache /usr/sbin/httpd -D FOREGROUND

Cleanup

  • Images: docker rmi `docker images -q`
  • Containers: docker rmi $(docker ps -a -q)
