Env vars for docker set up?

[andrewzah]

The docs link to a docker-compose.yml, but things seem to expect hardcoded dns names, such as backend. The Environment Variables page doesn't seem to mention them. How can I connect these services without hardcoded DNS?

services:
  foo:
    image: docker.io/apachestreampipes/backend:0.93.0
    environment:
      SP_HTTP_SERVER_ADAPTER_ENDPOINT: bar:8090
    ports:
      - "8030"
      - "8090"

  bar:
    image: docker.io/apachestreampipes/extensions-all-jvm:0.93.0
    environment:
      SP_HTTP_SERVER_ADAPTER_ENDPOINT: bar:8090
    ports:
      - "8030"
      - "8090"

  ui:
    image: docker.io/apachestreampipes/ui:0.93.0
    ports:
      - "8088"

Hi @andrewzah for extension services, you can provide the environment variable SP_CORE_HOST to link to the backend (you can also set SP_CORE_SCHEME in case the backend is running on HTTPS and SP_CORE_PORT to assign another port than the default port. The extension service itself can be any name since its IP is resolved at startup time, but this can be overriden by providing the SP_HOST and SP_PORT` variables.

For the reverse proxy configuration in the UI, you can change the default nginx configuration from https://github.com/apache/streampipes/blob/dev/ui/nginx_config/default.conf and add a volume mapping.

Hope this helps!

@dominikriemer SP_CORE_HOST doesn't seem to be working. The extension tries to register to itself (172.20.0.4) instead of core which is at 172.20.0.3.

Nevermind. I missed that setting SP_DEBUG messes with network routing.
