如果脚本退出，则在Dockerfile中停止Docker

Question

In my Dockerfile , I start a process using CMD:

# Start MyProcess
CMD ./my_process.sh >> /log/myprocess.log

my_process.sh may exit 0 according to some conditions inside that script. Is there a way to safely stop the container from running/starting? right now, it keeps restarting indefinitely

Answer 1

You can try leveraging restart policies, add below argument during docker run -

docker run --restart on-failure .....

--restart on-failure

Restart only if the container exits with a non-zero exit status. Optionally, limit the number of restart retries the Docker daemon attempts.
