无法从容器中删除所有泊坞窗

Question

I am trying to remove stop all docker containers on my ubuntu server but i keep getting "docker stop" requires at least 1 argument. Here is the relevant part of my Github Action file:

  - name: Deploy
    env:
        DOCKER_USER: ${{ secrets.DOCKER_USER }}
        DOCKER_PW: ${{ secrets.DOCKER_PW }}
    uses: appleboy/ssh-action@master
    with:
        host: ${{ secrets.DEVELOP_HOST }}
        username: ${{ secrets.DEVELOP_USERNAME }}
        password: ""
        key: ${{ secrets.DEVELOP_PRIVATE_KEY }}
        port: 22
        script: |
        ls
        sudo chmod 666 /var/run/docker.sock
        sudo docker pull username/reponame
        sudo docker stop $(docker ps -a -q)
        sudo docker rm $(sudo docker ps -q)
        sudo docker run -d -e NODE_ENV=develop -p 3000:3000 username/reponame

Output: "docker stop" requires at least 1 argument.

Anyone know what might be going on here?

Thanks in advance!

Answer 1

That means that $(docker ps -a -q) was evaluated to nothing.

sudo docker stop $(docker ps -a -q)

Output: "docker stop" requires at least 1 argument.

That is like whether you execute :

sudo docker stop 

It cannot work. One or more container are expected as args.

Either ignore the error :

sudo docker stop $(docker ps -a -q) || true

Or perform the stop on condition :

containerIds=$(docker ps -a -q)
if [[ -n $containerIds ]] ; then
  sudo docker stop $containerIds
