OpenEBS (Dedicated) Setup on Google Cloud Platform

Requirements

• Install Gcloud CLI

Usage

1. Prepare virtual machines and private network.

./prepare-vms.sh

After running script you should have 4 running VM's,

 $ gcloud compute instances list
NAME           ZONE           MACHINE_TYPE   PREEMPTIBLE  INTERNAL_IP  EXTERNAL_IP      STATUS
kubemaster-01  us-central1-f  n1-standard-2               10.240.0.10  x.x.x.x          RUNNING
kubeminion-01  us-central1-f  n1-standard-2               10.240.0.20  x.x.x.x          RUNNING
omm-01         us-central1-f  n1-standard-2               10.240.0.30  x.x.x.x          RUNNING
osh-01         us-central1-f  n1-standard-2               10.240.0.40  x.x.x.x          RUNNING

2. Copy required files on each node,

./copy-setup-files.sh

3. Run individual setup files,

You can ssh to a particular node using gcloud compute ssh <name>. Execute following steps to complete setup,

• kubemaster-01

$ ~/setup_k8s_master.sh

• kubeminion-01

Get token from kubemaster-01,

$ sudo kubeadm token list
TOKEN                     TTL         EXPIRES   USAGES                   DESCRIPTION
8d957d.55b14b6a44eadbce   <forever>   <never>   authentication,signing   The default bootstrap token generated by 'kubeadm init'.
kubectl get svc kubernetes -o json | jq -r '.spec.clusterIP'

Get cluster IP from kubemaster-01,

$ source ~/.profile
$ kubectl get svc kubernetes -o json | jq -r '.spec.clusterIP'

Run setup script,

$ #Example: ~/setup_k8s_host.sh -i <master_ip> -t <token> -c <cluster_ip>
$ ~/setup_k8s_host.sh -i 10.240.0.10 -t 8d957d.55b14b6a44eadbce -c 10.96.0.1

• omm-01

$ ~/setup_omm.sh

• osh-01

$ ~/setup_osh.sh -i <osh_ip>
$ ~/setup_osh.sh -i 10.240.0.30

4. If you want to cleanup all setup(GCE resources) later,

$ ./cleanup.sh

Verification

1. Kubernetes Setup

• Node status

$ source ~/.profile
$ kubectl get nodes
NAME            STATUS         AGE
kubemaster-01   Ready,master   1h
kubeminion-01   Ready          57m

2. OpenEBS Setup

• OpenEBS Node status

$ source ~/.profile
$ maya omm-status
$ maya osh-status
