Setup your own grafana on Openshift 3.11 plateform to monitor entire cluster resources and object.

-


Follow bellow steps to perform the setup

Create a New project first

oc new-project mygrafana

Get the existing grafana secret from openshift-monitoring project

oc get secrets grafana-datasources -n openshift-monitoring --export -o yaml > grafana-datasources.yaml

Now create secret in my own grafana project

oc create -f  grafana-datasources.yaml -n mygrafana

Now get the version of grafana that is being used in your openshift-monitoring namespace

[root@occontrol ~]# oc get deployment grafana -n openshift-monitoring  --export -o yaml | grep 'image: grafana'
        image: grafana/grafana:5.2.1

Now setup a deployment of the grafana using same image version

oc new-app --name=grafana grafana/grafana:5.2.1 -n mygrafana

Now we will mount the secret grafana-datasources.yaml in this new deployment.

# oc set volume dc/grafana --add --name=grafana-dashsources --type=secret --secret-name=grafana-datasources --mount-path=/etc/grafana/provisioning/datasources --namespace=mygrafana

Mount one empty dir also to /var/lib/grafana  path

# oc set volume dc/grafana --add --name=grafana-storage --mount-path=/var/lib/grafana --namespace=mygrafana

You can validate both mounted volume with bellow command

# oc set volume dc/grafana
deploymentconfigs/grafana
  secret/grafana-datasources as grafana-dashsources
    mounted at /etc/grafana/provisioning/datasources
  empty directory as grafana-storage
    mounted at /var/lib/grafana

Now we can create ingress for grafana deployment

oc expose svc/grafana -n mygrafana

you can access your custom grafana from url now.
In my case : http://grafana-mygrafana.apps.mylab.local

If you forgot root user password here is how you can modify . # virsh shutdown debian9-vm1 # virt-customize -a /var/lib/libvirt/images/debian9-vm1.qcow2 --root-password password:NewRootUserPasswordHere  not only this but you can edit many more. The –run-command option is used to execute any command inside a virtual image file. 1) register with rhel subscription virt-customize -a rhel-server-7.6.qcow2 --run-command 'subscription-manager attach --pool [subscription-pool]'     Install software or packages- virt-customize -a rhel-server-7.6.qcow2 --install net-tools  Upload a file into image virt-customize -a rhel-se...
