I am new to docker and trying to run supervisor and corn , but in this file it is just running supervisor. I know the problem is with last line but how can I fix it?

CMD /usr/bin/supervisord ; cron && tail -f /var/log/cron.log

CodePudding user response：

Because you are using ";" after the supervisor. So the command waits for supervisor the finish and after that cron will run. You can make it like:

CMD /usr/bin/supervisord & cron && tail -f /var/log/cron.log

so the supervisor will run in the back ground. Or if you want container the fail if supervisor fails you can do it like:

CMD cron && tail -f /var/log/cron.log  & /usr/bin/supervisord
