Pre-requisite

The supported versions are as follows:

This is the amsterdam branch which has diffrent rancher/helm/kubernetes/docker version levels - for master use the latest defined in ONAP on Kubernetes#Registeryourhost

Install helm client https://github.com/kubernetes/helm/releases

There are two parts to Helm: The Helm client (helm) and the Helm server (Tiller)

Installation procedure at: https://github.com/kubernetes/helm/blob/master/docs/install.md

...

Helm Client: https://storage.googleapis.com/kubernetes-helm/helm-v2.1https://storage.googleapis.com/kubernetes-helm/helm-v2.3.0-linux-amd64.tar.gz3-linux-amd64.tar.gz

wget https://storage.googleapis.com/kubernetes-helm/helm-v2.13.30-linux-amd64.tar.gz
tar -zxvf helm-v2.13.30-linux-amd64.tar.gz
sudo mv linux-amd64/helm /usr/local/bin/helm

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>

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

4. Create the Kubernetes host on OpenStack.

   
   

   1. Using Rancher API
      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
      Swap	16Go

      I added some swap because in ONAP, most of the app are not always active, most of them are idle, so it's fine to let the host store dirty page in the swap memory.
      {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

      Code Block

      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/'

   2. Doing it manually
      1. Create a VM in your VIM with the appropriate specs (see point above)

      2. Provision it with docker: You can find the proper version of Docker to install here (for Rancher 1.6): http://rancher.com/docs/rancher/v1.6/en/hosts/#supported-docker-versions

      3. Go in Rancher, Infrastructure → Hosts and click the button Add Host. "Copy, paste, and run the command below to register the host with Rancher:”
         
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

      Code Block
      ~/.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

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

7. Install kubectl

   Code Block
   curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.8.0/bin/linux/amd64/kubectl chmod +x ./kubectl sudo mv ./kubectl /usr/local/bin/kubectl

8. Make your kubectl use this new environment

   Code Block
   kubectl config use-context <rancher-environment-name>

9. After a little bit, your environment should be ready. To verify, use the following command

   Code Block

   $ kubectl get pods --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE kube-system heapster-4285517626-4dst0 1/1 Running 0 4m kube-system kube-dns-638003847-lx9f2 3/3 Running 0 4m kube-system kubernetes-dashboard-716739405-f0kgq 1/1 Running 0 4m kube-system monitoring-grafana-2360823841-0hm22 1/1 Running 0 4m kube-system monitoring-influxdb-2323019309-4mh1k 1/1 Running 0 4m kube-system tiller-deploy-737598192-8nb31 1/1 Running 0 4m
