Docker (compose)

[mawoka-myblock]

I think Docker would be a very nice addition since I'm having problems setting it up and docker(-compose) would make it way easier!

[Skabunkel]

I think so too, and I started working on a Dockerfile for it, but I'm a little out of it after work, so I'm like a few stairs short of a full shoe collection right now.

But I have something that I think work.
It's very dirty, but it's a start.

Dockerfile

FROM golang:1.17.3-buster AS base

#My brain is full of butterflies and spagett after work if i remove install npm it will not let me run dgraph make install (╯°□°)╯︵ ┻━┻
RUN apt-get -y update && apt-get -y install npm && curl -sL https://deb.nodesource.com/setup_15.x | bash - && apt-get -y update && apt-get -y install nodejs && apt-get -y clean
RUN npm install -g yarn

FROM base AS build-unigraph-dev-dgraph 

WORKDIR /src/dgraph
RUN git clone https://github.com/unigraph-dev/dgraph.git . && make install 

FROM build-unigraph-dev-dgraph  AS build-unigraph-dev

WORKDIR /src/unigraph
RUN git clone https://github.com/unigraph-dev/unigraph-dev.git .
RUN yarn install && yarn build-deps && npm install
RUN mkdir -p /data/unigraph

Build this with.
docker build -t unigraph-dev:latest .

docker-compose.yml

version: '3'

services:
  backend:
    image: unigraph-dev:latest
    entrypoint: ./scripts/start_server.sh -d /data/unigraph -b /go/bin/dgraph
    ports:
      - 3001:3001

  frontend:
    image: unigraph-dev:latest
    entrypoint: yarn explorer-start
    depends_on:
      - backend
    ports:
      - 3000:3000
      

Edit... I'm going to sleep now... the server port was in the wrong place, Good night.

I've created a more fleshed out version of this with SRP (separate dgraph image and services) - just running into a bug in the codebase itself but I'll get a PR in once I've got it all running properly

Edit: grammar

@Skabunkel's Dockerfile and compose file work for me as-is, but when I try to put the frontend behind Traefik it gives me this react-style SecurityError:

That's a websocket error. Unigraph tries to open a websocket to ws://hostname.com:3001. This works if everything is running on localhost, but if you have a proxy (nginx, traefik, etc) it won't be secure. Got some help in the discord; Two things to fix: 1 configure proxy to route websockets. 2 change unigraph websocket address

1. This is what a working nginx config looks like, I'm not familiar with traefik. Note the two location blocks, one for the ui, one for websockets on /ws/

server {
    server_name <hostname>;
    location / {
        proxy_pass http://localhost:3000;
    }
    location /ws/ {
        proxy_pass http://localhost:3001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Host $host;
    }

    # ssl / letsencrypt stuff
    listen [::]:443 ssl;
    listen 443 ssl;
}

2. Go to the running react-frontend. In settings, theres a config option for websocket url. use wss://hostename.com/ws/ (instead of ws://hostname.com:3001).

maybe try this one written by @101stArrow from Discord community?

version: '3.3'
services:
  dgraph-zero:
    ports:
      - '5080:5080'
      - '6080:6080'
    restart: unless-stopped
    image: ebdm/unigraph-dgraph
    command: dgraph zero --my=dgraph-zero:5080
  dgraph-alpha:
    ports:
      - '9080:9080'
      - '8080:8080'
    restart: unless-stopped
    image: ebdm/unigraph-dgraph
    command: dgraph alpha --my=dgraph-alpha:7080 --zero=dgraph-zero:5080 --whitelist="172.22.0.0/24"
networks:
  default:
    driver: bridge
    ipam:
      driver: default
      config:

          gateway: "172.22.0.1"

save to docker-compose.yml and simply docker compose up can set up dgraph but unigraph had to be manually configured
