Docker container shuts down giving 'data directory has wrong ownership' error when executed in windows 10 - postgresql

Question

I have my docker installed in Windows. I am trying to install this application. It has given me the following docker-compose.yml file:
version: '2'
services:
web:
build:
context: .
dockerfile: Dockerfile-nginx
ports:
- "8085:80"
networks:
- attendizenet
volumes:
- .:/usr/share/nginx/html/attendize
depends_on:
- php
php:
build:
context: .
dockerfile: Dockerfile-php
depends_on:
- db
- maildev
- redis
volumes:
- .:/usr/share/nginx/html/attendize
networks:
- attendizenet
php-worker:
build:
context: .
dockerfile: Dockerfile-php
depends_on:
- db
- maildev
- redis
volumes:
- .:/usr/share/nginx/html/attendize
command: php artisan queue:work --daemon
networks:
- attendizenet
db:
image: postgres
environment:
- POSTGRES_USER=attendize
- POSTGRES_PASSWORD=attendize
- POSTGRES_DB=attendize
ports:
- "5433:5432"
volumes:
- ./docker/pgdata:/var/lib/postgresql/data
networks:
- attendizenet
maildev:
image: djfarrelly/maildev
ports:
- "1080:80"
networks:
- attendizenet
redis:
image: redis
networks:
- attendizenet
networks:
attendizenet:
driver: bridge
All the installation goes well, but the PostgreSQL container stops after starting for a moment giving following error.
2018-03-07 08:24:47.927 UTC [1] FATAL: data directory "/var/lib/postgresql/data" has wrong ownership
2018-03-07 08:24:47.927 UTC [1] HINT: The server must be started by the user that owns the data directory
A simple PostgreSQL container from Docker Hub works smoothly, but the error occurs when we try to attach a volume to the container.
I am new to docker, so please ignore usage of terms wrongly.

Answer 1

This is a documented problem with the Postgres Docker image on Windows [1][2][3][4]. Currently, there doesn't appear to be a way to correctly mount Windows directories as volumes. You could instead use a persistent Docker volume, for example:
db:
image: postgres
environment:
- POSTGRES_USER=attendize
- POSTGRES_PASSWORD=attendize
- POSTGRES_DB=attendize
ports:
- "5433:5432"
volumes:
- pgdata:/var/lib/postgresql/data
networks:
- attendizenet
volumes:
pgdata:
Other things that didn't work:
Set PGDATA to a subdirectory (See PGDATA Setting)
environment:
- PGDATA=/var/lib/postgresql/data/mnt
volumes:
- ./pgdata:/var/lib/postgresql/data
Use a Bind Mount (docker-compose 3.2)
volumes:
- type: bind
source: ./pgdata
target: /var/lib/postgresql/data
Running as POSTGRES_USER=root

Answer 2

Please refer reinierkors' answer from here. The answer is as follows copied as is from the link here for reader's convenience and works for me
I solved this by mapping my local volume one directory below the one Postgres needs:
version: '3'
services:
postgres:
image: postgres
restart: on-failure
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=password
- PGDATA=/var/lib/postgresql/data/pgdata
- POSTGRES_DB=postgres
volumes:
- ./postgres_data:/var/lib/postgresql
ports:
- 5432:5432

Answer 3

I was having the same issue after downgrading my Docker from WSL 2 to WSL 1 and what Thomas Taylor's pertaining, I solved the issue by using named volume.
version: '3.8'
services:
postgres:
image: timescale/timescaledb:latest-pg12
...
volumes:
- pgdata:/var/lib/postgresql/data
...
volumes:
pgdata:

Answer 4

Map the local volume (e.g. C:\docker\pgdata) to one level (one directory) above what PostgreSQL needs. You can also do it from command line when starting the docker:
docker run -itd -e POSTGRES_USER=pguser -e POSTGRES_PASSWORD=pgpasswd \
-e PGDATA=/var/lib/postgresql/data/pgdata -p 5432:5432 \
-v c:\docker\pgdata:/var/lib/postgresql --name postgresql postgres

Answer 5

I met this issue when re-installed docker and used wsl-1 backend.
solution: switch docker to wsl-2 backend.

Answer 6

Even i had the problem i had to copy the data dir at regular intervals.
docker cp <container-name>:/var/lib/postgresql/data C:/docker/volumes/postgres

Answer 7

Owner for the data folder in postgres inside the container is Postgres user. Your current user may not have access privilege in the mounted folder. You need to give all permissions according to the requirements by given command below :
chmod 777 ./docker/pgdata
If this command is not helping to resolve this issue please refer the following link to do the user mapping from inside the container to outside the container.
