problem
There is a problem with the elasticsearch ready probe when running on a single replica cluster.
Warning Unhealthy 91s (x14 over 3m42s) kubelet Readiness probe failed: Waiting for elasticsearch cluster to become ready (request params: "wait_for_status=green&timeout=1s" ) Cluster is not yet ready (request params: "wait_for_status=green&timeout=1s" )
Solution:
If you are running a single copy cluster, add the following helm values:
clusterHealthCheckParams: "wait_for_status=yellow&timeout=1s"
For a single replica cluster, your status will never turn green.
The following values should be valid:
replicas: 1 minimumMasterNodes: 1 clusterHealthCheckParams: 'wait_for_status=yellow&timeout=1s'
