Docker is a software system for creating and running containers.
Prune old docker files
docker system prune -a
Build and run a Dockerfile
docker run -it \ -p 70:70 \ -d \ $(docker build -q .)
Container OS / CoreOS randomly kills my containers
You can prevent this by writing SystemD service files that restarts your containers when they die. In this scenario, SystemD acts as a watchdog. You can also observe the container states and logs via SystemD if you do this.
