Run multiple instances of Docuseal (prod/dev) ?

[apcloic]

Hi,
I'm not familiar with Docker and Caddy, does anybody know th best way run another instance of Docuseal using a subdomain on the same VPS for test/development purpose ?

@apcloic you need to create Caddyfile with two subdomains - here is an example Caddy file: #184 (comment)

yourdomain.com {
  reverse_proxy * {
    to app:3000
  }
}
staging.yourdomain.com {
  reverse_proxy * {
    to stagingapp:3000
  }
}

and then in docker-compose define a second docuseal stagingapp service with staging psotgresql

Thanks a lot for your help !
Regarding docker-compose, it should look like this ?
No risk to mess with the data on disk between app and staging_app ?

docker_compose.yml

version: '3'

services:
  app:
    depends_on:
      postgres:
        condition: service_healthy
    image: docuseal/docuseal:latest
    ports:
      - 3000:3000
    volumes:
      - .:/data
    environment:
      - FORCE_SSL=true
      - DATABASE_URL=postgresql://postgres:postgres@postgres:5432/docuseal

  staging_app:
    depends_on:
      staging_postgres:
        condition: service_healthy
    image: docuseal/docuseal:latest
    ports:
      - 3000:3000
    volumes:
      - .:/data
    environment:
      - FORCE_SSL=true
      - DATABASE_URL=postgresql://postgres:postgres@postgres:5432/docuseal


  postgres:
    image: postgres:15
    volumes:
      - './pg_data:/var/lib/postgresql/data'
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: docuseal
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 5s
      timeout: 5s
      retries: 5

  staging_postgres:
    image: postgres:15
    volumes:
      - './pg_data:/var/lib/postgresql/data'
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: docuseal
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 5s
      timeout: 5s
      retries: 5


  caddy:
    image: caddy:latest
    ports:
      - 80:80
      - 443:443
      - 443:443/udp
    volumes:
      - .:/data
      - ./Caddyfile:/etc/caddy/Caddyfile
   

Caddyfile

mydomain.com {
  reverse_proxy * {
    to app:3000
  }
}
staging.mydomain.com {
  reverse_proxy * {
    to staging_app:3000
  }
}

@apcloic you need to update staging mounted directories to make sure the data won't be shared between apps:

[apcloic]

@omohokcoj Thank you very much 👌

@omohokcoj

Almost done, last issue is :

Bind for 0.0.0.0:3000 failed: port is already allocated

So I've tried to change the port mapping in staging_app :

  staging_app:
    depends_on:
      staging_postgres:
        condition: service_healthy
    image: docuseal/docuseal:latest
    ports:
      - 4000:3000
    volumes:
      - .:/data
    environment:
      - FORCE_SSL=true
      - DATABASE_URL=postgresql://postgres:postgres@postgres:5432/docuseal

Then I run :

 docker compose up --force-recreate -d

And the issue is gone.

app is working properly but staging_app return an error 500.

So I've also tried to change Caddyfile like this :

staging.mydomain.com {
  reverse_proxy * {
    to staging_app:4000
  }

but it's worst than error 500, I get no page found error.

Any idea ?

Here's the error log, I don't clearly see what's wrong...

@apcloic you need to use staging postgresql URL

[apcloic]

@omohokcoj you rock !

Everything is working as expected after setting the database_url properly like this !

  staging_app:
    depends_on:
      staging_postgres:
        condition: service_healthy
    image: docuseal/docuseal:latest
    ports:
      - 4000:3000
    volumes:
      - .:/data
    environment:
      - FORCE_SSL=true
      - DATABASE_URL=postgresql://postgres:postgres@staging_postgres:5432/docuseal

Thanks a lot for your help.
