Cannot link to database from other container about postgres

[yosifkit]

I am not able to reproduce this. I used your exact commands.

I did freshly pull images this morning, perhaps there was a bad one earlier.

$ docker images postgres
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
postgres            9.2.13              6d0256095934        2 days ago          264.1 MB
postgres            9.2                 6d0256095934        2 days ago          264.1 MB

Ah you pointed me in the right direction. See this:

$ docker pull postgres:9.2
9.2: Pulling from docker.io/postgres

See how the image ID of docker.io/postgres:9.2 and postgres:9.2 do not match?

What I do not know is why, though, since I pulled it.

Anyway, repeating the same steps with the image docker.io/postgres:9.2 still fails the same way 😞

Nevermind, seems a bug in Docker itself or in Fedora's package.
