Unable to start neo4j container (Permission denined)

Greetings everyone,

I'm unable to start neo4j container when I run docker-compose. I get the following errors in docker logs:

> docker logs neo4j
Changed password for user 'neo4j'.
chown: /data/dbms/auth.ini: Permission denied
chown: /data/dbms: Permission denied
chown: /data/dbms: Permission denied
chown: /data: Permission denied
chown: /data: Permission denied

I have verified that read/write permissions are there for the signed in user on the corresponding files and directories. Any idea how can I fix this?

The core of the issue lies with bind mounted volumes. Previously, docker desktop had elevated privileges / permissions but now after shifting over to colima, the same privileges were no longer there.

User permissions weren't being passed on properly to the containers, resulting in them being unable to access the binded volumes on the host machine. The solution is to add a user:group or uid:gid mapping in the docker run command or the docker-compose file etc.

user: "<uid>:<gid>"

In a docker-compose file, it would look like this:

version: '3.4'
services:
  neo4j:
      image: neo4j:3.5.5
      container_name: neo4j
      ports:
          - 7474:7474
          - 7687:7687
      volumes:
          - ./example/docker/neo4j/conf:/conf
          - ./.local/neo4j/data:/var/lib/neo4j/data
      user: '1000'
      group_add:
      - '1000'
