[EROR] Misconfigured feedback email setting: feedback@localhost

Troubleshooting
1

Hi,

Today i wanted to try out your platform, I have decided to run all in Docker. Just like in the manual I installed all stuff that i need and then i started the container, after 5 minutes of waiting and trying to refresh the page, I decide to show into the docker container logs - and there i saw a weird error message:

[09/03/15 09:43:27] [INFO] Loading config file at /config_docker.json
[09/03/15 09:43:27] [EROR] Misconfigured feedback email setting: feedback@localhost

at this point the container is frozen, and i can’t open the site. What can I do to fix it?

Cheers,
Damian

That message is cause because it’s missing the field "FeedbackEmail" in the configuration, but no idea why it hangs the container as it should also put a default instead of an empty field. Maybe it could be logged as Warning instead of Error.

3

That log msg should be a warning and can safely be ignored.

Do you see the log messages below? which would mean the server is running.
[09/03/15 09:27:52] [INFO] Starting Server…
[09/03/15 09:27:52] [INFO] Server is listening on 8065
[09/03/15 09:27:52] [INFO] RateLimiter is enabled

This is my whole log when i start the container:

user@ci0:~$ docker logs --tail="all" mattermost-dev
 * Running /etc/init.d/networking restart is deprecated because it may not re-enable some interfaces
 * Reconfiguring network interfaces...

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

  /usr/bin/mysqladmin -u root password 'new-password'
  /usr/bin/mysqladmin -u root -h 93a34736d477 password 'new-password'

Alternatively you can run:

  /usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

This looks like the log for container console output not mattermost (we do print some initial msgs to the console before file logging is enabled). Can you shell into the container and look at the mattermost logs? Should be something like

docker exec -ti mattermost-dev /bin/bash
cd mattermost/ogs
cat mattermost.og
