Hello, I’m trying to install a test installation via docker. The installation process up to step 3 (https://docs.mattermost.com/install/prod-docker.html) worked without a problem but I can’t use the platform cli on the app server. I alway get the following error when trying to execue a command (e.g. create a user):
[2017/08/12 10:21:30 CEST] [EROR] Failed to ping DB retrying in 10 seconds err=dial tcp 127.0.0.1:5432: getsockopt: connection refused
The webinterface is working and I can create a user with it. I didn’t do any steps after point 3 because this is only a local test installation in a virtual machine with docker.
I tried to open up the 5432 tcp port with the yast firewall but it didn’t help either.
Seems that your app container try to reach your database on localhost. I’m pretty sure it should not, can you provide your docker-compose.yml file please ? (don’t forget to remove/obfuscate your credentials)
I didn’t change any content of the docker.compose.yml (even the passwords and username, because I just wanted to test the first steps of the installation routine) except for commenting out the enterprise-option for the installtion.
I don’t understand why your container try to contact your database on localhost, but I think this is the problem. Is there any special DNS configuration on your setup ?
I don’t know why but the problem seems to be gone now (I didn’t change anything, only some reboots of the docker host and docker containers). Maybe it just needed some time to get all the connections correctly.
