karaf broker url inside docker container - windows

Question

So I am working on creating a docker container for a camel project. In the project I am sending data to a messaging queue using apache karaf .

Now when the project is ran normally, ie without as a container , it works properly. The karaf broker url is - tcp://localhost:61616 . This value is coming from a config file inside the camel project.

But when I create the container error is thrown -

Cannot connect to the broker url - tcp://localhost:61616

My guess is 'localhost' inside the docker wouldn't be considered the localhost of my machine (laptop) . Inside the container , locahost would be it's own IP address, I believe.

So, what address should I put for the broker url? 127.0.0.1? or my laptop's external IP?

Answer 1

If you camle project is running as docker container and karaf on host then you need to connect to karaf using host ip address. You can change broker url in config like below

tcp://host_ip:61616

As docker container is also like a vm and it has its own network and isolated form host, so localhost for host and container is different.
