[Gluster-users] gluster-heketi-kubernetes

[Jose A. Rivera]

Try adding the following lines to the deploy-heketi-deployment.yaml
and heketi-deployment.yaml files around line 53 (keeping indentation
with other similar lines):

          - name: HEKETI_KUBE_NAMESPACE
            value: default

Replace "default" with the namespace you're using for these pods.

Are you using gk-deploy or running the deployment manually? If the
former, and your DaemonSet is running succesfully, rerun it without
the -g flag.
