ubuntu 20.04 sudenly using port 5432?
I was using a postgres docker just fine with ubuntu 18.04. Now I updated to ubuntu 20.04 and I suddenly can no longer start the docker, since the following error pops up - notice this error keeps appearing after freshly booting:
$ sudo docker start pg
Error response from daemon: driver failed programming external connectivity on endpoint pg (d188f0712e7079530a6d82eaf8c8770ca0ba8b755e41d87810a691e945725f52): listen tcp4 0.0.0.0:5432: bind: address already in use
Error: failed to start containers: pgNow to see what process might be using that port I tried netstat -nlp however this gave the unhelpful line:
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN - Indicating that "no PID/program name" is using that port. - What is causing ubuntu to block the common postgres port suddenly. And can I update either docker to use a different port or prevent ubuntu of blocking that port? (Without breaking stuff).
With lsof I find that a postgres database runs on that address: but what has changed with the update from 18.04 to 20.04 that suddenly this address is used? Can I find which tool is responsible for this?
$ sudo lsof -i tcp:5432
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
postgres 1285 postgres 3u IPv4 37282 0t0 TCP localhost:postgresql (LISTEN)pstree -s 1285 (or correct version after rebooting) gives the following response:
systemd───postgres───6*[postgres]hunting the startup processes using sudo systemctl list-unit-files --type=service
returns amongst the lines the following:
postgresql.service enabled enabled
postgresql@.service indirect enabledBut this still doesn't give me a clue what caused the postgres service to start running on my pc (or what application is responsible).
