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

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
