deploy-eck update 1

OUTDATED - Please use this link for the new script and instructions

https://www.gooksu.com/2022/09/new-elastic-kubernetes-script-deploy-elastick8s-sh/


I developed the deploy-eck.sh script to easily deploy the elastic stack in k8s to quickly test things.

Did a quick update to the script.

  • operator mode. Now you can run the script just to deploy the operator only and apply a trial license. You can develop your own test cases etc in this mode. If you work out of ~/eckstack and name your manifest files *.yaml when you run the deploy-eck.sh cleanup it will cleanup all of your items as well.
> ./deploy-eck.sh cleanup

  • Changed the fleet mode to add a LB endpoint to the fleet server. Previously you could only reach fleet server if you were in the k8s environment only. Now that LB endpoint is added you can reach it via the network. - this leads to fun things!
$ kubectl get svc | egrep "NAME|fleet"

  • fleet matured a lot going from 7.x -> 8.0 -> 8.2+++ and starting with 8.2+ you can add multiple outputs to your fleet settings so that you can use logstash. By using logstash it opens up a possiblity to send your data to a different deployment! For the fleet mode anything above 8.2.0, the script will configure the external output and a External Agent Policy using the external output so that you can easily register elastic-agent from outside of k8s environment to send send data into your elastic stack hosted on k8s. Also starting 8.2+ I added the fingerprint of the CA and added ssl.verification_mode: none to make ingestion from the outside easier.
