Docker-compose postgres error: FATAL: password authentication failed for user "postgres" - postgresql

Question

I have an error with postgres in docker-compose. When I start docker-compose with docker-compose up -d, everything is right. But after 1-2 days, the error occurs. And I noticed, that when it occurs the linux machine become really slow, and I can't do any operations with docker. I tried: sudo systemctl restart docker.service to restart docker daemon, but it just stops and do nothing. But when I reboot machine, the lags disappear. I consider that something wrong with config(docker-compose.yml).
Here's my docker-compose.yml:
volumes:
common-volume:
postgres:
services:
nginx:
container_name: nginx
image: nginx:latest
ports:
- '80:80'
volumes:

Answer 1

I had confronted similar issue. The problem is with this line of code for both postgresql and auth_service configuration:
restart: always
replace it with:
restart: no
or comment it out!
