EDIT 2: After a long time, solved! See answer below.
EDIT: I am sorry to say that the the problems went away "on their own" between yesterday and today, without me having done anything. Great non-deterministic lesson to learn here...Bonus fun: the "could not bind IPv6 socket" error still appears in the error logs, so this was probably not even the problem in the first place.
I have a problem with a previously functioning docker PGSQL image. Until an uninspired rebuild yesterday ( :-D ), I've used this build successfully for the last 5+ months.
My system:
- Ubuntu 17.04 64b
- PGSQL 9.6.4
- Docker version 17.11.0-ce, build 1caf76c
- I am mapping host port 5433 to container port 5432
The problem (snippet from the PGSQL logs):
...
LOG: could not bind IPv6 socket: Cannot assign requested address
HINT: Is another postmaster already running on port 5432? If not, wait a few seconds and retry.
...
This is what ss is telling me (when the container is running, obviously):
$ docker exec -it db ss -atune Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port udp ESTAB 0 0 127.0.0.1:45876 127.0.0.1:45876 uid:999 ino:147509 sk:00000001 <-> tcp LISTEN 0 128 127.0.0.1:5432 *:* uid:999 ino:147500 sk:00000002 <->I've cleaned all docker containers / images, I've reinstalled docker, nothing helped. Who can possibly be using the 5432 port in the container?For that matter, am I reading this correctly, that PGSQL is complaining about the 5432 port being already used in the docker container?
Even if you have no solution, a basic idea of how to proceed with debugging this would be a great help.
