I'm trying to run a Docker container every other minute that is stopped via cron job but it seems not working.
What I've done is launch the command crontab -e and add the line
*/1 * * * * docker start sender >> /home/cronlog.log 2>&1
I've added the user group to Docker as explained here (in fact I can access docker from the terminal without sudo)
I have also tried to add the command into a script as below
*/1 * * * * /home/start_container.sh >> /home/cronlog.log 2>&1
with the script containing
#!/bin/sh
docker start sender
but still, nothing happens. The cron process is working tho as using the command ps -ef | grep cron I got
root 881 1 0 08:42 ? 00:00:00 /usr/sbin/cron -f -P
nicola 10905 10178 0 11:31 pts/0 00:00:00 grep --color=auto cron
Am I missing something? (Obviously, the commands work if launched manually from the terminal)
It turned out that, for some reason, the cron doesn't like the /home/ (at least, in this specific instance)
I've fixed using another path such as
*/1 * * * * docker start sender >> /tmp/cronlog.log 2>&1
