检查容器退出状态的快速方法

Question

I need a fast way to check if a containers has exited in a scriptable way. Currently using docker library with python but that creates too much overhead.

docker inspect -f {{.State.Status}} $CONTAINER_PID Any suggestions?

Answer 1

Try doing it by using the subprocess package (the shell=True is important):

import subprocess

output = subprocess.check_output(r"docker inspect -f {{.State.Status}} $CONTAINER_PID", shell=True).decode()

print(output)
