I got this error when i tried to install elasticsearch by kubernetes . I setup my server with configuration of 8 GB RAM. Could it be out of memory. How can i fix it ? I am using your configuration on minikube

@early-lamp-41924 might have some ideas.

Hey! What's the error code you see on the top side of this kubectl describe pod?

Do you mean this ?

Looks like they are dying due to OOM. Since they are being OOM killed

cluster setup has 4 CPUs and 8 GB RAM. And no other systems else are running

We've seen that the default config for elastic search uses a lot of resources. 3 Nodes with 2cpu and 8gb of ram were required 😢 You can try adjusting the resource limit for the elastic pod in the prerequisites-values.yaml !

When i tried to install components of datahub, it happened some components not be installed and gms component ran into error

For single server install : docker based install is the simplest. Is there a specific reason you have to use the k8s based deployment for single server?

Error 137 is out of memory. You are runnung out of resources. Probably bc elasticsearch is taking all the space.

Our System are running on Kubernetes. I want to test DataHub out before integrating into the system. Our server config is setup with 4 CPUs and 8GB RAM and it seems to be not enough. Is there any way i can run elasticsearch with one node instead of 3 nodes right now or 3 nodes are compulsory and it's not going to be changed ? If it's so, can you recommand for me the rational config for my sever that can gets rid off the out of memory error, please ?

In the prerequisites-value.yaml there are configurations that I commented out. Those configs were designed for minikube (single node local kubernetes), so it should work for this case as well.
