PostgreSQL with docker ownership issue - postgresql

Question

Since yesterday, I try to launch my docker project on Windows (Bootcamp MacBook Pro), and I have just one issue left : PostgreSQL image.
Error message :
postgres_1 | The files belonging to this database system will be owned by user "postgres".
postgres_1 | This user must also own the server process.

postgres_1 | The database cluster will be initialized with locale "en_US.utf8".

I've searched everywhere, tried everything, and still have this issue…
What I tried is :
Create docker volume with docker volume create --name postgres -d local and use it in my docker-compose.yml
docker-compose.yml
version: '2'
services:
postgres:
image: postgres:latest
ports:
- "5432:5432"
volumes:
- postgres:/var/lib/postgresql/data
networks:
internal_ip:
ipv4_address: 192.168.1.2
volumes:
postgres:
external: true
Add volume directly in docker compose
volume sample
volumes:
postgres:
driver: local
Using relative or absolute Windows paths
Declare multiple volumes for differents PostgreSQL folders (conf, data…)
I tried to docker compose down, restart computer, remove images, nothing change, same error.
I already checked Shared Drive box in Docker Settings.

Is anyone as a working solution ? I will continue to make it work, and update post if I found Something.
Thanks in advance.

Answer 1

I've finally figured out what went wrong when I tried to use a volume for PostgreSQL data.
I had no idea that we used a docker-compose.override.yml, which declare a volume with a Windows path.
So here is a working solution to have PostgreSQL on Docker for Windows, with persisted data :
version: '2'
services:
postgres:
image: postgres:11.5
ports:
- 5432:5432
volumes:
- pgdata:/var/lib/postgresql/data
- pgconf:/etc/postgresql
- pglog:/var/log/postgresql
volumes:
pgdata:
driver: local
pgconf:
driver: local
pglog:
driver: local
(no additional command required)

Answer 2

container_name: postgresql
image: postgres:latest
environment:
POSTGRES_PASSWORD: postgres
# volumes:
# - "./database:/var/lib/postgresql/data/"
ports:
- "5432:5432"
Comment the volumes
This work around did the trick and worked on windows, i have to bring those two lines back on mac but that's the easiest way to work for now until some real solution get pushed by docker windows or posgres docker
