Kubernetes yaml templates or Helm chart

[dkirrane]

Wondering if you have any K8s templates or Helm chart for standing up ELK with SearchGaurd in a Kubernetes cluster

Hey @dkirrane I was about to suggest using kompose. But after testing it locally it fails since the docker-compose.yml uses build and context and the Kompose maintainers still on it.
Check this issue

I think this is way beyond the scope of this project. Here is an excellent starting point for running ELK on Kubernetes:

You should be able to swap the images and get it running with Searchguard without problem.

@jemacom , kompose issue is fixed now :)
Please download latest kompose release 1.6 for latest changes

@surajnarwade I think am still facing some issues although am using the 1.6 release.

$kompose version                                               
1.6.0 (e4adfef)

$kompose up -v

FATA Error while deploying application: k.Transform failed: image key required within build parameters in order to build and push service 'elasticsearch'

Any thoughts on this ? Thanks.

@jemacom you need to mention image key in your services in docker compose file. then kompose will build your image with that name, push it to registry and then your cluster will pull it and deploy :)

I'm not sure how far you managed to get with that ELK on Kubernetes story, but I found the following Helm charts in the Kubernetes GitHub org:

• https://github.com/kubernetes/charts/tree/master/incubator/elasticsearch
• https://github.com/kubernetes/charts/tree/master/incubator/logstash
• https://github.com/kubernetes/charts/tree/master/stable/kibana

All 3 charts use the same Docker images as we do in this project and seem easy to configure. In my opinion this is by far more elegant and maintainable than using Kompose.

I suggest you give it a shot. I will close this issue in a few days because Kubernetes is a very special beast that do not share much with our Compose setup, but I welcome further discussion if you need guidance.
