Docker is awesome #

There is something in containerization and virtualization that attracts me very much. I think it’s the ultimate separation of concerns, the break down of complexity and declouping of system components.

Running a container exposing a port: #

Exposes the container 80 port as a local/host 8080:

docker run -p 8080:80 edpichler/nginx

Entering inside a running docker container #

   docker exec -it e4383e55958d /bin/bash

Listeing all containers: #

docker ps -a

Deleting forcevily all the containers: #

docker rm -f $(docker ps -a -q)

Deleting all images that are not being used by running containers #

The additional filter is to do not delete recently downloaded images.

docker image prune -a --filter "until=24h"
