# OpenShift and KubeVirt Multinode Demo



## Deploying OpenShift with Vagrant



This will create an OpenShift cluster with one manster and one node via

Vagrant:



### OpenShift



```bash

make cluster-up

make cluster-openshift

```



The deployment can take pretty long. Also you will not see much output from the

openshift installer while it is running. To see what is going on in the installer run



```bash

vagrant ssh master -c "tailf /ansible.log"

```



Once the deployment is done, you can directly talk to the master via `./oc.sh`:



```bash

$ ./oc.sh get nodes

NAME      STATUS    ROLES     AGE       VERSION

master    Ready     master    3h        v1.9.1+a0ce1bc657

node      Ready         3h        v1.9.1+a0ce1bc657

```



**Note**: Right now we only support having a **single** master.



### Storage Provisioner



To deploy `storage` run



```

make cluster-storage

```



Once it is done, you can see the storage deployed:



```bash

$ ./oc.sh get pods -n kube-system

NAME          READY     STATUS    RESTARTS   AGE

ceph-demo-0   7/7       Running   2          52m

```



To test the installation, start a pod which requests storage from that

provisioner:



```bash

$ ./oc.sh create -f examples/storage-pod.yaml

$ /oc.sh get pvc

NAME       STATUS    VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS        AGE

demo-pvc   Bound     pvc-2d1a98e1-12ef-11e8-a1c4-525400cc240d   1Gi        RWO            standalone-cinder   24m

$ ./oc.sh get pv

NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS    CLAIM              STORAGECLASS        REASON    AGE

pvc-2d1a98e1-12ef-11e8-a1c4-525400cc240d   1Gi        RWO            Delete           Bound     default/demo-pvc   standalone-cinder             24m

```



### KubeVirt



To deploy `KubeVirt` run



```

make cluster-kubevirt

```



Once it is done, you can see all KubeVirt pods deployed:



```bash

$ ./oc.sh get pods -n kube-system

NAME                              READY     STATUS    RESTARTS   AGE

virt-controller-66d948c84-kmfxs   0/1       Running   0          17m

virt-controller-66d948c84-mmmnx   1/1       Running   0          17m

virt-handler-64sjz                1/1       Running   0          17m

virt-handler-ps8ds                1/1       Running   0          17m

```



To test the installation, start a vm with alpine:



```bash

$ ./oc.sh create -f examples/vm.yaml

$ sleep 300 # We need to pull a lot when the first vm starts on a node

$ ./oc.sh get vms -o yaml | grep phase

    phase: Running

```



To connect to a VM:



```bash

./oc.sh console demo-vm  # Serial console

./oc.sh vnc demo-vm      # VNC

```



To import and run a cirros vm:



```bash

$ ./oc.sh create -f examples/import-cirros.yaml

$ sleep 120  # The cirros disk image downloads into a PVC

$ ./oc.sh get pod disk-importer  # Repeat until pod is Completed

$ ./oc.sh create -f examples/vm-cirros-clone.yaml

$ ./oc.sh get vms -o yaml | grep phase

    phase: Running

```



## ManageIQ - kubevirt provider configuration



To configure `KubeVirt provider` run



```

make cluster-miq

```



Once it is done, you can see that service account was created



```bash

./oc.sh get sa

NAME       SECRETS   AGE

builder    2         20m

default    3         19m

deployer   2         20m

miq        2         19s

registry   3         14m

router     2         14m

```



and offlinevms custom resource was created



```bash

./oc.sh get offlinevms

No resources found.

```



In order to configure provider in `ManageIQ` there are two tokens needed by running



```bash

./oc.sh sa get-token -n management-infra management-admin



./oc.sh sa get-token -n default miq

```



## Deploying OpenShift on arbitrary nodes



First create an inventory:



```

[nodes]

node1 ansible_host=192.168.200.4 ansible_user=root

node2 ansible_host=192.168.200.3 ansible_user=root



[master]

master ansible_host=192.168.200.2 ansible_user=root

```



Save it in `myinventory`. Then run



```bask

ansible-playbook -i myinventory openshift.yaml

ansible-playbook -i myinventory storage.yaml

ansible-playbook -i myinventory kubevirt.yaml
