This is a problem that could happen if you try to mount a volume in this way:
https://stackoverflow.com/questions/45632593/postgres-docker-container-data-fails-to-mount-to-local
I solved this problem creating a volume :
docker volume créate --name paneek
and later only using it on my docker-compose.yml:
version: '2'
services:
app:
build:
context: ./
dockerfile: app.dockerfile
working_dir: /var/www
volumes:
- ./:/var/www
links:
- pgsql
web:
build:
context: ./
dockerfile: web.dockerfile
working_dir: /var/www
volumes_from:
- app
ports:
- 80:80
links:
- app
pgsql:
image: "postgres:9.5"
#to be available to use pgadmin
ports:
- 5432:5432
environment:
POSTGRES_USER: postgres
POSTGRES_DB: postgres
POSTGRES_PASSWORD: local
volumes:
- paneek:/var/lib/postgresql/data
volumes:
paneek:
Note: On Windows with toolbox there is not another way to do it.
