Can't seem to connect to conainer from other container on first run? about dokku-pg-plugin HOT 4 CLOSED

I am running into same issue. Have a container running, sockets listening there, other container linked and configured, but my app (django w/psycopg2) cannot connect to it, and even using psql directly does.

dokku on digital ocean Ubuntu 14.04 as of today.

from dokku-pg-plugin.

I am suspecting the db container is not being linked to the app. I tried to run my app container explicitly asking to link with the db container and got psql to connect.

something like this: docker run -i -t --link :db /bin/bash

and from there I psql using the proper parameters.

dokku-pg-plugin uses dokky config:set when I ask it to link, how is the networking side of this being handled? shouldn't it also link the container at docker level?

thanks.

@phsilva Thank god somone else that has this weird issue. Can you reconfirm that we are talking about the same issue?

I.e.

• Create psql container using dokku postgresql:create my-db-container
• Start in another container try to connect to this port and ip adresss, should result in blocked
• Telnet on the host or psql to the postgresql cotnainer establishing network
• Start the container and then see that you can connect.

I.e. initial connect from the container seem to be blocked unless linkig it with docker link?

In my case I only got a connection after I linked the two containers (at
docker level), which changed the connection parameters a little big and I
had to config:set it manually.
