Where to find clues
If you run into issues, there are a couple main places to look for clues.
- If you know what service is failing, usually the best place to look is in the logs for the problimatic service:
./tc logs <SERVICE_NAME>
.
- You can see what services are currently running, as well as the status by running
docker service ls
. This can sometimes help identify services that just aren't starting due to a configuration error.
- Occasionally there is a service that is failing before the can even start, and thus doesn't output any logs. In these situations monitoring the Docker service can be very helpful. Run
journalctl -f -u docker
or journalctl -r -u docker
to see the exact error.
- Check the documentation dedicated to the service you're having trouble with. Links can be found on the Supported Services page.
