             Summary: Investigate ElasticSearch memory requirements on B24 cluster
                 Key: SWSQE-294
                 URL: https://issues.jboss.org/browse/SWSQE-294
             Project: Kiali QE
          Issue Type: Bug
            Reporter: Kevin Earls
            Assignee: Guilherme Baufaker Rêgo
            Priority: Minor


On minishift and the CNCF CI OpenShift cluster, we install ElasticSearch using the commands:

    curl https://raw.githubusercontent.com/RHsyseng/docker-rhel-elasticsearch/5.x/es-cluster-deployment.yml --output es-cluster-deployment.yml
    oc create -f es-cluster-deployment.yml

However, on B24 this fails.  The first 2 elasticsearch pods will start up, but then elasticsearch-2 gets into the following failure loop like:

elasticsearch-2   1/1       Running   3         1m
elasticsearch-2   0/1       OOMKilled   3         1m
elasticsearch-2   0/1       CrashLoopBackOff   3         2m

If I increase memory in the es-cluster-deployment.yml to 1Gi it will at least start, but I've found I really need to increase it to 2Gi to do anything non trivial.  

We may need to track down the people who originally created this template for help on this.
