Installed with Docker getting Bad Gateway 502 error

[ahansson89]

I installed with the steps in the wiki for Docker. The container runs, but it is returning 502 Bad Gateway.

I had this problem. Turned out the PostgreSQL container was restarting continuously because of an SELinux denial.

The fix:

diff --git a/docker-compose.yml b/docker-compose.yml
index c4901648..7b48e1af 100644
--- a/docker-compose.yml

Note as well that is can take a couple of minutes for the assets to be compiled and the website to become available.

had to remove the "/data" and force 9.3 version.
