Install OS and Provisioner plugin for K8S

                                    Install OS and Provisioner plugin for K8S 

1) Download the following configuration (.yaml) files from below location .

 wget http://archive.mapr.com/tools/KubernetesDataFabric/v<version>/*.yaml

2) Use the kubectl create command with the -f option to create the namespace for the plug-in and provisioner

[root@tssperf09 K8S]# kubectl create -f kdf-namespace.yaml

namespace "mapr-system" created

[root@tssperf09 K8S]# 

3) Now use the kubectl create command with -f option to install the Role bases Access control.

[root@tssperf09 K8S]# kubectl create -f kdf-rbac.yaml

serviceaccount "maprkdf" created

clusterrole "mapr:kdf" created

clusterrolebinding "mapr:kdf" created

[root@tssperf09 K8S]#

4) Modify kdf-plugin-centos.yaml  and add  Host IP and port of your API server.

 env:

          - name : KUBERNETES_SERVICE_LOCATION

            value: "10.10.72.249:6443"

          - name : FLEXVOLUME_PLUGIN_PATH

            value: "/usr/libexec/kubernetes/kubelet-plugins/volume/exec"

5) Now use the kubectl create command with -f option to create OS plug-in depending your specific OS.

[root@tssperf09 K8S]# kubectl create -f kdf-plugin-centos.yaml

daemonset "mapr-kdfplugin" created

[root@tssperf09 K8S]#

In this step there are 2 stages 

Stage 1 )  Copy files/lib from the container image to plugin dir.

Stage 2 )  Copy plugin files from plugin dir to /opt/mapr

All the logs of interest for installation of the plugin are under /opt/mapr/logs/install-k8s-plugin.log  

Logs for Plugin init is under /opt/mapr/logs/plugin-k8s.log

6) Use the kubectl create command with the -f option to install the provisioner on a single node of the Kubernetes cluster

[root@tssperf09 K8S]# kubectl create -f kdf-provisioner.yaml

deployment "mapr-kdfprovisioner" created

[root@tssperf09 K8S]#

If everything went well you will see a pod will be running a provisioner , in this particular case POD is running on node tssperf11 .

[root@tssperf09 logs]# kubectl get pods --all-namespaces -o wide --sort-by=.status.hostIP | grep -i provisioner

mapr-system   mapr-kdfprovisioner-79b86f459d-hjkcn      1/1       Running   0          13d       192.168.217.130   tssperf11.lab

[root@tssperf09 logs]#

To list all the services running on all the pods in K8S cluster below command would be handy.

[root@tssperf09 K8S]# kubectl get pods --all-namespaces -o wide --sort-by=.status.hostIP
