We at dropbit are fond of docker


Build, Ship and Run Any App, Anywhere. We don’t have to worry about where our applications are running. If we neeed to do a server update, we don’t have to fear anymore. We can move away the applications running on this server very quickly. Then we can do server updates and afterwards if everything went well, we move back our applications to the updated server. With docker our application infrastructure became much simpler. dropbit therefore decided to share our experience with docker. From now on we will blog regularly about docker. In this first blog we just show some important commmands, you have to now. We are sure you will become fond of docker too. It’s just a matter of time.

delete all images

sudo docker rmi $(sudo docker images -f "dangling=true" -q)

container commands

docker ps

show all containers

docker ps -a

run a container from an image

docker run --name myimage_instance -i -t myimage:latest

docker tag bd393c80a9ca localhost:5000/dropbitbase
docker push localhost:5000/dropbitbase

This overview was thought just for our team initially. But why not sharing the list with you. If you have some more important commands to add to the overwiew, then just let us know.
