Self Hosted Collab Excalidraw with containers

[lunitaris]

Hello,

I want to setup a self hosted environnement using the 2 containers: excalidraw and excalidraw-room
There is no documentation on how to connect / link the client to the server..

I tried to set the variable REACT_APP_WS_SERVER_URL, but nothing.
Could you guys help me please?
How to make this work?

docker pull docker.io/excalidraw/excalidraw
docker pull docker.io/excalidraw/excalidraw-room

docker run -d -p 8081:80 excalidraw/excalidraw-room:latest
docker run -d -p 8080:80 -e REACT_APP_WS_SERVER_URL=http://127.0.0.1:8081 excalidraw/excalidraw:latest

Thx

Have a look at this docker compose setup, maybe it helps? https://github.com/b310-digital/excalidraw/blob/master/docker-compose.yml

I tried to use this docker-compose using portainer and at some point it fails.

Start of logs:

I haven't figured out how to solve this yet.

can you try using image: ghcr.io/kitsteam/excalidraw-storage-backend:v0.1.0 instead of

build: 
      context: https://github.com/kitsteam/excalidraw-storage-backend.git#main
      target: production

[Fofanius]

Still Deploymend error but with a little change at the end:

and after reboot my homelab server

Ok, first of all there was my mistake at line 7, there is . instead of https://github.com/b310-digital/excalidraw.git#master.
But replacing didn't help ... :(

Well, I managed to deploy it in Portainer with next docker-compose script:

version: "3.8"

services:
  excalidraw:
    stdin_open: true
    build:
      context: https://github.com/b310-digital/excalidraw.git#master
      target: development
    container_name: excalidraw
    ports:
      - "3000:3000"
    restart: on-failure
    healthcheck:
      disable: true
    environment:
      - NODE_ENV=development
    volumes:
      - node_modules:/opt/node_app/node_modules
      - ./:/opt/node_app/
    networks:
      - excalidraw-net
      - reverse-proxy-net

  excalidraw-storage-backend:
    stdin_open: true
    build: 
      context: https://github.com/kitsteam/excalidraw-storage-backend.git#main
      target: production
    ports:

    environment:

      STORAGE_TTL: 2592000000
    networks:
      - excalidraw-net
      - reverse-proxy-net

  excalidraw-room:
    image: excalidraw/excalidraw-room
    ports:

    command: redis-server --requirepass ${REDIS_PASSWORD}
    volumes:

    networks:

BUT collaboration still does not work with following pop-up message: Error \n Couldn't connect to the collab server. Please reload the page and try again.

[Fofanius]

Have a look at this docker compose setup, maybe it helps? https://github.com/b310-digital/excalidraw/blob/master/docker-compose.yml

Even if I clone the repository completely and run docker-compose from it on my local machine, all containers seem to start, but nothing happens in them (no logs) and the ability to collaborate is still missing :(

Any ideas?

[JannikStreek]

well, check the logs...docker compose logs excalidraw-storage-backend, most likely its database related, e.g. you haven't provided the .env file. A default is existing, but you need to provide your own, otherwise database stuff is missing. This is not really issue related anymore, so you can write me a mail (see commit mail) but it's not really issue related anymore ;-)

[l4rm4nd]

I have solved the problem.
