Multiple instances of SS in Docker

Deployment
#1

We are trying to run multiple instances of SS using docker. We were able to run these instances on different ports:

website.com:8000
website.com:7000

How can we change that to survey1.website.com or website.com/survey1 and so on?

We used the yml file from here and simply changed the port numbers from ports and baseurl lines.

Hi, @ashwinikalantri

Basically You need a reverse proxy to run and route request before those docker images.

For a sample please take a look at this repo: https://github.com/surveysolutions/docker-compose/tree/multiplehq

In this sample repo I use Traefik to handle all incoming request at port 80:

 traefik:
    image: traefik:v2.4
    command:
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
    volumes:
    - "/var/run/docker.sock:/var/run/docker.sock:ro"
    restart: always
    ports:
      - "80:80"

Then I configure HQ services using using docker labels for Traefik like this:

  hq1:
    image: surveysolutions/surveysolutions
    depends_on:
     - "db"
    environment: 
      HQ_ConnectionStrings__DefaultConnection: Server=db;Port=5432;User Id=postgres;Password=pg_password;Database=hq1
      HQ_Headquarters__BaseUrl: http://${HQ1_HOST}
    volumes:
      - ./data/app1:/app/AppData
    restart: always
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.hq1.rule=Host(`${HQ1_HOST}`)"

  hq2:
    image: surveysolutions/surveysolutions
    depends_on:
     - "db"
    environment: 
      HQ_ConnectionStrings__DefaultConnection: Server=db;Port=5432;User Id=postgres;Password=pg_password;Database=hq2
      HQ_Headquarters__BaseUrl: http://${HQ2_HOST}
    volumes:
      - ./data/app2:/app/AppData
    restart: always
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.hq2.rule=Host(`${HQ2_HOST}`)"

Full Docker Compose Yaml configuration can be found here: https://github.com/surveysolutions/docker-compose/blob/multiplehq/docker-compose.yml

HQ1_HOST and HQ2_HOST just are predefined in /.env file in root of repository to hq1.lvh.me and hq2.lvh.me ( *.lvh.me domains are always resolved to 127.0.0.1 )

If You clone/fork this repo at branch multiplehq and run docker-compose up, then after a while HQ should be available at predefined addresses:

Thank you all for the possible solutions. But with the release of Workspaces in 21.01, this implementation has been rendered moot! This will be tremendous helpful for us.
