Hello everybody,
I've setup a 3 node kafka cluster running on kubernetes using stateful sets and
headless services.
The problem is now I want read/write data from/to the cluster from outside the
cluster.
I have found a couple of suggestions here
https://stackoverflow.com/questions/41868161/kafka-in-kubernetes-cluster-how-to-publish-consume-messages-from-outside-of-kub.
Essentially, I've found 2 options:
1. Use hostNetwork: true when starting the kafka container and use as
ADVERTISED_HOST in kafka the kubernetes worker node - this has
2. Use Services type NodePort to expose the kafka broker port to the
outside world - drawback here is that it will open a port on all worker nodes
and second the request will go through the kube proxy
On top of this I still need to sync my external dns system with the dns of
the kafka worker nodes.
Could anyone share their experience on how they achieved this?
Thanks,
George
