im getting an error while running elasticsearch on kubernetes. I dont believe this is a memory allocation issue but i dont know. Trying to set it up with discovery - not a single node.
here is my kubernetes config for elasticsearch - https://hastebin.com/ohiyivinit.bash
Here is my error on startup from kubectl logs
Exception in thread "main" java.lang.RuntimeException: starting java failed with [137]
output:
error:
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

The error code strongly suggests this is a memory issue.
Since you're using GKE, if Stackdriver is enabled, you can use the following advanced filter to confirm if this is an OOM kill:
resource.type="container"
resource.labels.cluster_name="YOUR_CLUSTER"
resource.labels.namespace_id="NAMESPACE"
resource.labels.project_id="PROJECT_ID"
resource.labels.zone:"ZONE"
resource.labels.container_name="CONTAINER_NAME" # Container name, not pod name
resource.labels.pod_id:"POD_NAME-" # Notice that is not the full pod ID
"OOM"
If you find out this is an OOM issue, you can set requests and limits to your deployment to ensure the resources are enough to run your application.
