How to deploy a horizontally scalable cluster?

[seepine]

After reading the introduction, we found that citus perfectly met our requirements, but the deployment documentation was unfriendly. How to deploy a horizontally scalable cluster?

Eg in Node 1 of 192.168.1.1

service:
  master1:
    image:citusdata/citus:12.1
    ports:
      - 5432:5432
    volumes:
      - ./data1:/data
    environment:
      - CITUS_CLUSTER: 192.168.1.2,182.168.1.3

Eg in Node 1 of 192.168.1.2

service:
  master2:
    image:citusdata/citus:12.1
    ports:
      - 5432:5432
    volumes:
      - ./data2:/data
    environment:
      - CITUS_CLUSTER: 192.168.1.1,182.168.1.3

Eg in Node 1 of 192.168.1.3

service:
  master3:
    image:citusdata/citus:12.1
    ports:
      - 5432:5432
    volumes:
      - ./data3:/data
    environment:
      - CITUS_CLUSTER: 192.168.1.1,182.168.1.2

And users can connect to any node.

• 192.168.1.1:5432
• 192.168.1.2:5432
• 192.168.1.3:5432

I'm not sure if my understanding is wrong, but if citus can support such horizontal scalability and it can still work when a certain node fails, then it will be very powerful.
