ONAP on Kubernetes on Rancher

Rancher

1. Create a plain Ubuntu VM in your cloud infrastructure.

   The following specs are enough for Rancher

   ID	3
   VCPUs	2
   RAM	4Go
   Taille	40Go

2. Setup Rancher stable by running this command:

   docker run -d -p 8080:8080 rancher/server:v1.6.10

3. Navigate to Rancher UI

   http://<rancher-vm-ip>:8080

4. Setup basic access control: Admin → Access Control
5. Install Openstack as machine driver: Admin → Machine Drivers

We're now all set to create our Kubernetes host.

1. Create an environment
   1. Default → Managed Environments
   2. Click Add Environment
   3. Fill in the Name and the Description
   4. Select Kubernetes as Environment Template
   5. Click Create
2. Create an API key: API → Keys
   1. Click Add Account API Key
   2. Fill in the Name and the Description
   3. Click Create
   4. Backup the Access Key and the Secret Key
3. Retrieve your environment ID
   1. Navigate to the previously created environment

   2. In the browser URL, you should see the following, containing your <env-id>

      http://<rancher-vm-ip>:8080/env/<env-id>/kubernetes/dashboard

4. Create the Kubernetes host. Make sure to fill in the placeholder as follow:

   {API_ACCESS_KEY}: The API KEY created in the previous step
   {API_SECRET_KEY}: The API Secret created in the previous step
   {OPENSTACK_INSTANCE}: The OpenStack Instance Name to give to your K8S VM
   {OPENSTACK_IP}: The IP of your OpenStack deployment
   {RANCHER_IP}: The IP of the Rancher VM created previously
   {K8S_FLAVOR}: The Flavor to use for the kubernetes VM. Recommanded specs:

   VCPUs	8
   RAM	64Go
   Taille	100Go

   {UBUNTU_1604}: The Ubuntu 16.04 image
   {PRIVATE_NETWORK_NAME}: a private network
   {OPENSTACK_TENANT_NAME}: Openstack tenant
   {OPENSTACK_USERNAME}: Openstack username
   {OPENSTACK_PASSWORD}: OpenStack password

   curl -u "{API_ACCESS_KEY}:{API_SECRET_KEY}" \
   -X POST \
   -H 'Accept: application/json' \
   -H 'Content-Type: application/json' \
   -d '{
   "hostname":"{OPENSTACK_INSTANCE}",
   "engineInstallUrl":"wget https://raw.githubusercontent.com/rancher/install-docker/master/1.12.6.sh",
   "openstackConfig":{
       "authUrl":"http://{OPENSTACK_IP}:5000/v3",
       "domainName":"Default",
       "endpointType":"adminURL",
       "flavorName":"{K8S_FLAVOR}",
       "imageName":"{UBUNTU_1604}",
       "netName":"{PRIVATE_NETWORK_NAME}",
       "password":"{OPENSTACK_PASSWORD}",
       "sshUser":"ubuntu",
       "tenantName":"{OPENSTACK_TENANT_NAME}",
       "username":"{OPENSTACK_USERNAME}"}
   }' \
   'http://{RANCHER_IP}:8080/v2-beta/projects/{ENVIRONMENT_ID}/hosts/'

5. Let's wait a few minutes until it's ready.
6. Get your kubectl config
   1. Click Kubernetes → CLI
   2. Click Generate Config

   3. Copy/Paste in your host, under

      ~/.kube/config

      If you have multiple Kubernetes environments, you can give it a different name, instead of config. Then reference all your kubectl config in your bash_profile as follow

      KUBECONFIG=\
      /Users/adetalhouet/.kube/k8s.adetalhouet1.env:\
      /Users/adetalhouet/.kube/k8s.adetalhouet2.env:\
      /Users/adetalhouet/.kube/k8s.adetalhouet3.env
      export KUBECONFIG

7. Make your kubectl use this new environment

   kubectl config use-context <environment-name>

8. After a little bit, you're environment should be ready. To verify, use the following command

   $ kubectl get pods --all-namespaces
   NAMESPACE     NAME                                   READY     STATUS    RESTARTS   AGE

   kube-system   tiller-deploy-737598192-8nb31          1/1       Running   0          4m
