I have a project where I use google compute engine to host my app and docker to containerize it.
I have a postgres image and I want to use a volume to make my data persistent when I restart the container. Moreover I want the db data to be stored in google storage. So I have a google storage bucket and I have mounted a directory in my google compute engine to that bucked. Specifically what I did is mkdir /home/vetter_leo/data where data is the folder I want to use as a volume and then I mount it using gcsfuse --dir-mode 777 --file-mode 777 -o allow_other --implicit-dirs artifacts.helenos-273112.appspot.com /home/vetter_leo/data/.
My dockerfile for the postgres image is this :
FROM postgres:latest
USER postgres
ENV POSTGRES_USER helenos
ENV POSTGRES_PASSWORD helenos
ENV POSTGRES_DB helenos
ENV PGDATA /var/lib/postgresql/data/pgdata
COPY init_helenos_schema.sql /docker-entrypoint-initdb.d/
EXPOSE 5432
and my docker-compose file is this :
version: "3.5"
services:
postgres:
container_name: postgres
image: postgres
build:
context: .
dockerfile: ./postgres.prod.dockerfile
volumes:
- /home/vetter_leo/data:/var/lib/postgresql/data
networks:
default:
external:
name: helenos-network
When doing docker-compose -f docker-compose.yml up -d --build I end up with the container not being started and this error is shown chmod: changing permissions of '/var/lib/postgresql/data/pgdata': Operation not permitted.
I have searched the web but so far I have not been able to find a solution for my problem. Any help would be greatly appreciated. Thanks.
