Script for simple management and updating of docker containers. Like docker-compose, but more flexible and with single-command upgrade functionality.

Dockerscript

#!/bin/sh
# ./Dockerscript <prefix>

name=helloworld
[ -n "$PREFIX" ] && prefix=-$PREFIX
set -e

start() {
  docker network create --driver bridge $name$prefix
  docker run -id --restart=always --network=$name$prefix -v "$PWD/files:/data" --name=$name$prefix-main "$@" hello-world
}

stop() {
  for s in main; do
    docker stop $name$prefix-$s &&
    docker rm $name$prefix-$s || true
  done
  docker network rm $name$prefix || true
}

build() {
  docker build --pull --no-cache -t $name .
}
