Bad Gateway 502 error - nginx about docker-gitlab

[sameersbn]

Please make sure that you are allowing the application enough time to start.
A typical docker log will look like this https://gist.github.com/sameersbn/b5b99fb72ed4eb22908f

You have to wait until you see the below lines in the log.

If you make requests to the gitlab application before this you will see the 500 errors since the application has not started yet, but should respond correctly once its up. Please check if this is the case.

If you are still seeing this issue then just try restarting the container.
A few people have reported this issue but they have found that restarting the container fixes this issue. I think that its got something with gitlab.

If you are seeing this issue consistently, try running the image without any arguments

docker run -i -t sameersbn/gitlab

If you do not see the issue after this, then maybe it could be a problem with the application arguments.

OK, I will try that.

This is what I see in unicorn.stderr.log:

I, [2014-02-03T11:10:18.193141 #234]  INFO -- : Refreshing Gem list

[riaanvddool]

Via docker logs:

fatal: Not a git repository (or any of the parent directories): .git
rake aborted!
Host '172.17.42.1' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'

Later on in the log:

@riaanvddool If the mysql error, can you add the parameter

-e "DB_POOL=10"

to the run command and retry. If it still does not work, try increasing the number.

[riaanvddool]

I restarted the (separate) mysql docker and the "is blocked because of many connection errors" message disappeared.

Now I get:

Access denied for user 'gitlab'@'172.17.42.1' (using password: YES)

Looking into that now...

[sameersbn]

@riaanvddool You mean you are using the mysql docker container? i.e. https://github.com/sameersbn/docker-mysql
If yes, then edit the https://github.com/sameersbn/docker-mysql/blob/master/resources/setup/commands.sql file appropriately and rebuild the mysql docker images.

[riaanvddool]

I am using https://github.com/orchardup/docker-mysql.

The problem seemed to be with a line in https://github.com/orchardup/docker-mysql/blob/master/run

GRANT ALL PRIVILEGES ON . TO 'root'@'%';
should have read
GRANT ALL PRIVILEGES ON . TO 'root'@'%' WITH GRANT OPTION;

The omission of the "WITH GRANT OPTION" part stopped root from granting privileges to the gitlab user.

I see that in your file (https://github.com/sameersbn/docker-mysql/blob/master/resources/setup/commands.sql) you have the "WITH GRANT OPTION" part.

Thanks for the pointers, I hope this might help someone else.

@riaanvddool glad to hear that the issue is resolved for you.
