/var/lib/docker/containers/ does not exist in docker compose bindings in WSL2

Question

I'm trying to host wings inside docker using the official wings docker image. I used docker desktop for my windows installation. I have a modified config below:

services:
  db:
    image: postgres:13
    restart: always
    container_name: corkscrew-db
    environment:
      POSTGRES_USER: user
      POSTGRES_PASSWORD: pass
      POSTGRES_DB: data
    ports:
      - "5432:5432"
  wings:
    image: ghcr.io/pterodactyl/wings:latest
    restart: always
    networks:
      - wings0
    ports:
      - "8080:8080"
      - "2022:2022"
    tty: true
    environment:
      TZ: "UTC"
      WINGS_UID: 988
      WINGS_GID: 988
      WINGS_USERNAME: pterodactyl
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "/var/lib/docker/containers/:/var/lib/docker/containers/" #\\wsl.localhost\docker-desktop-data\data\docker\volumes
      - "./wings/etc/pterodactyl/:/etc/pterodactyl/"
      - "./wings/var/lib/pterodactyl/:/var/lib/pterodactyl/"
      - "./wings/var/log/pterodactyl/:/var/log/pterodactyl/"
      - "./wings/tmp/pterodactyl/:/tmp/pterodactyl/"
      - "./wings/etc/ssl/certs:/etc/ssl/certs:ro"
  web:
    image: node:20.9.0-alpine3.18
    container_name: corkscrew-web
    ports:
      - "5173:5173"
    env_file:
      - .env.dev
    volumes:
      - ./:/app
      - /app/node_modules/
    working_dir: /app
    command: sh -c "yarn && yarn run db:deploy && yarn run seed && yarn run dev --host --port 5173"
    depends_on:
      - db

  
networks:
  wings0:
    name: wings0
    driver: bridge
    ipam:
      config:
        - subnet: "172.21.0.0/16"
    driver_opts:
      com.docker.network.bridge.name: wings0

However, when trying to run it, I encounter an error:

Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /var/lib/pterodactyl/volumes/8f8caa88-7152-46a0-a448-de4168b809e6 

I tried using \\wsl.localhost\docker-desktop-data\data\docker\volumes for my path (this does exist), however, replacing it for my docker volume binding isn't working, and the volumes folder isn't present at all.

Answer 1

I was looking at the problem all wrong here. Rather than an issue with mounting the docker volumes directory, the issue seemed from this binding: "./wings/var/lib/pterodactyl/:/var/lib/pterodactyl/". Behind the scenes, the docker container uses a linked docker.sock to create a docker container on the host machine; however, during this process, a /var/lib/pterodactyl/ directory was never created on the host machine, meaning it would throw an error. To resolve this, the config can be changed to the following:

services:
  db:
    image: postgres:13
    restart: always
    container_name: corkscrew-db
    environment:
      POSTGRES_USER: user
      POSTGRES_PASSWORD: pass
      POSTGRES_DB: data
    ports:
      - "5432:5432"
  wings:
    image: ghcr.io/pterodactyl/wings:latest
    restart: always
    networks:
      - wings0
    ports:
      - "8080:8080"
      - "2022:2022"
    tty: true
    environment:
      TZ: "UTC"
      WINGS_UID: 988
      WINGS_GID: 988
      WINGS_USERNAME: pterodactyl
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "./var/lib/docker/containers/:/var/lib/docker/containers/" #\\wsl.localhost\docker-desktop-data\data\docker\volumes
      - "./wings/etc/pterodactyl/:/etc/pterodactyl/"
      - "/var/lib/pterodactyl/:/var/lib/pterodactyl/" #changed from "./wings/var/lib/pterodactyl/:/var/lib/pterodactyl/"
      - "./wings/var/log/pterodactyl/:/var/log/pterodactyl/" 
      - "./wings/tmp/pterodactyl/:/tmp/pterodactyl/"
      - "./wings/etc/ssl/certs:/etc/ssl/certs:ro"
  web:
    image: node:20.9.0-alpine3.18
    container_name: corkscrew-web
    ports:
      - "5173:5173"
    env_file:
      - .env.dev
    volumes:
      - ./:/app
      - /app/node_modules/
    working_dir: /app
    command: sh -c "yarn && yarn run db:deploy && yarn run seed && yarn run dev --host --port 5173"
    depends_on:
      - db

  
networks:
  wings0:
    name: wings0
    driver: bridge
    ipam:
      config:
        - subnet: "172.21.0.0/16"
    driver_opts:
      com.docker.network.bridge.name: wings0

This allows the container to create new containers using the docker.sock and create the directory in needs to mount into the new container.
