### Hello! On the server we installed the docker. The docker compose file came from here: https://github.com/mattermost/mattermost-docker Isn't a config/config.json so i created one and copy the content from here: https://github.com/mattermost/platform/tree/master/config and add premmissions for this. After that i checked a postgresql database. Verified the connect with the user, it's ok. #### with docker-compose up i get this: ``` mattermost_db_1 | AWS_ACCESS_KEY_ID is required for Wal-E but not set. Skipping Wal-E setup. mattermost_app_1 | Using config file /mattermost/config/config.json mattermost_app_1 | Configure database connection...SKIP mattermost_app_1 | Wait until database db:5432 is ready... mattermost_app_1 | nc: getaddrinfo: Name or service not known mattermost_web_1 | linking plain config mattermost_web_1 | ln: failed to create symbolic link '/etc/nginx/conf.d/mattermost.conf': File exists mattermost_web_1 | 2017/06/16 13:31:07 [emerg] 10#10: host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_web_1 | nginx: [emerg] host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_db_1 | LOG: database system was shut down at 2017-06-16 12:45:41 CEST mattermost_db_1 | LOG: MultiXact member wraparound protections are now enabled mattermost_db_1 | LOG: database system is ready to accept connections mattermost_db_1 | LOG: autovacuum launcher started mattermost_mattermost_web_1 exited with code 1 mattermost_app_1 | nc: getaddrinfo: Name or service not known mattermost_web_1 | linking plain config mattermost_web_1 | 2017/06/15 11:30:51 [emerg] 8#8: host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_web_1 | nginx: [emerg] host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_web_1 | ln: failed to create symbolic link '/etc/nginx/conf.d/mattermost.conf': File exists mattermost_web_1 | linking plain config mattermost_web_1 | 2017/06/15 11:30:52 [emerg] 8#8: host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_web_1 | nginx: [emerg] host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_app_1 | nc: getaddrinfo: Name or service not known mattermost_mattermost_web_1 exited with code 1 mattermost_app_1 | nc: getaddrinfo: Name or service not known mattermost_web_1 | linking plain config mattermost_web_1 | 2017/06/15 11:30:51 [emerg] 8#8: host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_web_1 | nginx: [emerg] host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_web_1 | ln: failed to create symbolic link '/etc/nginx/conf.d/mattermost.conf': File exists mattermost_web_1 | linking plain config mattermost_web_1 | 2017/06/15 11:30:52 [emerg] 8#8: host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_web_1 | linking plain config mattermost_web_1 | ln: failed to create symbolic link '/etc/nginx/conf.d/mattermost.conf': File exists mattermost_web_1 | 2017/06/16 13:31:11 [emerg] 8#8: host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_web_1 | nginx: [emerg] host not found in upstream "app" in /etc/nginx/conf.d/mattermost.conf:21 mattermost_app_1 | nc: getaddrinfo: Name or service not known mattermost_app_1 | nc: getaddrinfo: Name or service not known mattermost_mattermost_web_1 exited with code 1 mattermost_app_1 | nc: getaddrinfo: Name or service not known mattermost_app_1 | nc: getaddrinfo: Name or service not known ``` #### Docker ps show this: ``` mattermost/mattermost-prod-web "/bin/sh -c /docker-e" 26 hours ago Restarting (1) 7 seconds ago 0.0.0.0:81->80/tcp, 0.0.0.0:444->443/tcp mattermost_mattermost_web_1 5b0c92c80cd3 mattermost/mattermost-prod-app "/docker-entry.sh pla" 26 hours ago Up 24 seconds 80/tcp mattermost_mattermost_app_1 21bcbb5d9761 mattermost/mattermost-prod-db "/docker-entrypoint1." 12 days ago Up 24 seconds 5432/tcp mattermost_mattermost_db_1 ad1eb0cfe67c gitlab/gitlab-runner:latest "/usr/bin/dumb-init /" 4 months ago Up 4 months ``` #### I tried to check it with curl: ``` /mattermost/bin# curl -i http://localhost:81 curl: (7) Failed to connect to localhost port 81: Connection refused ``` So about this is the situation.

We are trying to fix this issue [on Github](https://github.com/mattermost/mattermost-docker/issues/142). Thanks for your log information, I think that there is an issue with the link between your containers. (btw @lindy65 in case of Docker issues, feel free to mention me 🙂 ) ---
