Error response from daemon: cannot stop container - signaling init process caused "permission denied"解決方法

I was having the same issue I solved it by executing a shell in the docker container using this command docker exec -it imagebase bash then issuing kill 1 command.

docker exec -it flask-app-cont  /bin/bash
kill 1

進入你的container中，輸入kill 1 就可以把容器停掉了。
