Parse Server on Openstack with multiple User accounts (alternative to back4app, Heroku)

Question

I'm a student and at college we're trying to setup our own backend service for our applications, as Backend like Firebase would cost us more.

We settled up on using Openstack to combine and manage the compute resources of multiple computers together in our college Lab, but now we want to make a web portal where our students can login and use the parse server dashboard.

How to setup multiple parse instances for each user and what containers to use and how?

Answer 1

You can try with docker compose. You would need to write a docker-compose.yml file like this:

version: '2'

services:
  mongo-db:
    image: mongo
    ports:
      - 27017:27017
  parse-server1-user1:
    image: parseplatform/parse-server
    links:
      - mongo-db
    environment:
      - PARSE_SERVER_APPLICATION_ID=parse1-user1
      - PARSE_SERVER_MASTER_KEY=SOME_SECRET_MASTER1_USER1
      - PARSE_SERVER_DATABASE_URI=mongodb://mongo-db:27017/parse1-user1
    ports:
      - 1337:1337
  parse-server2-user1:
    image: parseplatform/parse-server
    links:
      - mongo-db
    environment:
      - PARSE_SERVER_APPLICATION_ID=parse2-user1
      - PARSE_SERVER_MASTER_KEY=SOME_SECRET_MASTER2_USER1
      - PARSE_SERVER_DATABASE_URI=mongodb://mongo-db:27017/parse2-user1
    ports:
      - 1338:1337
  parse-server1-user2:
    image: parseplatform/parse-server
    links:
      - mongo-db
    environment:
      - PARSE_SERVER_APPLICATION_ID=parse1-user2
      - PARSE_SERVER_MASTER_KEY=SOME_SECRET_MASTER1_USER2
      - PARSE_SERVER_DATABASE_URI=mongodb://mongo-db:27017/parse1-user2
    ports:
      - 1339:1337
  parse-server2-user2:
    image: parseplatform/parse-server
    links:
      - mongo-db
    environment:
      - PARSE_SERVER_APPLICATION_ID=parse2-user2
      - PARSE_SERVER_MASTER_KEY=SOME_SECRET_MASTER2_USER2
      - PARSE_SERVER_DATABASE_URI=mongodb://mongo-db:27017/parse2-user2
    ports:
      - 1340:1337
  parse-dashboard:
    image: parseplatform/parse-dashboard
    links:
      - parse-server1-user1
      - parse-server2-user1
      - parse-server1-user2
      - parse-server2-user2
    depends_on:
      - parse-server1-user1
      - parse-server2-user1
      - parse-server1-user2
      - parse-server2-user2
    environment:
      - PARSE_DASHBOARD_CONFIG={"apps":[{"appId":"parse1-user1","serverURL":"http://localhost:1337/parse","masterKey":"SOME_SECRET_MASTER1_USER1","appName":"parse1-user1"},{"appId":"parse2-user1","serverURL":"http://localhost:1338/parse","masterKey":"SOME_SECRET_MASTER2_USER1","appName":"parse2-user1"},{"appId":"parse1-user2","serverURL":"http://localhost:1339/parse","masterKey":"SOME_SECRET_MASTER1_USER2","appName":"parse1-user2"},{"appId":"parse2-user2","serverURL":"http://localhost:1340/parse","masterKey":"SOME_SECRET_MASTER2_USER2","appName":"parse2-user2"}],"users":[{"user":"user1","pass":"secret-pass1","apps":[{"appId":"parse1-user1"},{"appId":"parse2-user1"}]},{"user":"user2","pass":"secret-pass2","apps":[{"appId":"parse1-user2"},{"appId":"parse2-user2"}]}]}
      - PARSE_DASHBOARD_ALLOW_INSECURE_HTTP=1
    ports:
      - 4040:4040

Then run:

docker-compose up -d
