Access services from docker container

I am trying to connect to an service (rabbitmq) from a container that I manually run in my bitbucket pipeline. But with no luck. Is this even possible?

Problem is that I have no glue what address/ip/name I could provide to my container for the service. The rabbitmq service starts fine and would be accessible under localhost:5672, but not from within my container, cause this will run in a diffrent network.

Here´s a small example what my setup looks like

image: microsoft/dotnet:sdk
pipelines:
 default:
   - step:
 caches:
   - dotnetcore
 script: # Modify the commands below to build your repository.
   - docker build -t company/image:tag -f ./company/service/Dockerfile ./company/service
   - docker run -d --name mycontainer -p 8000:80 -e ASPNETCORE_ENVIRONMENT=Development -e MESSAGEBUS="$CONNECTIONSTRINGS__APITESTSRABBITMQ" company/image:tag
 services:
   - docker
   - rabbitmq
definitions: 
 services: 
   rabbitmq:
     image: rabbitmq:3-alpine
options:
 docker: true

I have defined an environment variable CONNECTIONSTRINGS__APITESTSRABBITMQ with value rabbitmq://guest:guest@localhost:5672, but this is wrong cause rabbitmq is not accessible under this address from my container.

So is it possible to access a service from my container?

I am not sure if this is the correct way, but using --network="host" in docker run command, makes the rabbitmq is accessible via localhost from within my container
