Redis – My local volume for mongodb gets permission denied when running docker-compose up

Here is my docker-compose.yml

version: "3.5"
services:
  api:
    container_name: upvotocracy-api
    restart: always
    build: .
    env_file: .env
    ports:
      - "127.0.0.1:8537:8537"
      - "127.0.0.1:9228:9229"
    links:
      - mongo
    volumes:
      - ./index.js:/usr/src/app/index.js
      - ./.env:/usr/src/app/.env
    networks:
      - upvotocracy-network
  mongo:
    container_name: upvotocracy-mongo
    restart: always
    image: mongo:latest
    env_file: .env
    volumes:
      - ./mongo_data:/data/db
    ports:
      - "127.0.0.1:28016:27017"
    networks:
      - upvotocracy-network
  redis:
    image: redis
    restart: always
    container_name: upvotocracy-cache
    ports:
      - "127.0.0.1:6381:6379"
    networks:
      - upvotocracy-network
  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.6.2
    container_name: upvotocracy-es01
    restart: always
    environment:
      - node.name=es01
      - cluster.name=es-docker-cluster
      - cluster.initial_master_nodes=es01
      - bootstrap.memory_lock=true
      - action.auto_create_index=+*
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - ./data01:/usr/share/elasticsearch/data
    ports:
      - 127.0.0.1:9201:9200
    networks:
      - upvotocracy-network
networks:
  upvotocracy-network:
    name: upvotocracy-network
volumes:
  mongo_data: {}
  data01:
    driver: local

It only works when I run docker-compose up as root, otherwise I get a permission denied error on ./mongo_data directory which is owned by 999:ubuntu

    For me I just had to add ./mongo_data to .dockerignore and the Dockerfile would ignore this directory while building api.

    I did this for all my volumes and things work fine now, no permission errors.

    I had the same problem.
    I assume that you didn’t have this permission error at your first time of docker-compose up.
    The
    The file “mongo_data/diagnostic.data” did not exist either. The mongo container will create the file when starting, and the file belongs to a user, it’s 999:root in my case(postgres). 

    drwx------ 19            999 root            4096 Jun  4 12:19 postgres-data/

    Your api container has the current directory as the build context. The user who builds the docker is your host user, it has to not be 999. So when you docker-compose up would have the permission denied.
    You can create a .dockerignore file in the context folder, the content is:

    mongo_data

    You have to add other folders in this file in the volumes of other containers.
