Install Kubernetes with minikube

Instruction for installing minikube for running any ONAP component or whole onap.

Make sure you install correct versions of Kubernetes, kubectl and Helm to match the particular ONAP version. Find out required versions for onap e.g. from https://docs.onap.org/en/latest/submodules/oom.git/docs/oom_cloud_setup_guide.html.

Minikube

There's not known requirements for minikube version, you may install latest version.

Kubernetes

Example with ONAP El-Alto version of Kubernetes

Start minikube

minikube start --kubernetes-version=1.15.2

NOTE: Kubernetes version ALWAYS needs to be given explicitly.

NOTE: If you are running minikube on a dedicated linux box add "--vm-driver=none"

You may also want to give additional minikube parameters depending on your machine capabilities and amount of ONAP components to be installed e.g.

"--cpus 4 --memory 8192 --disk-size 50g"

for cpus memory and disk size.

Kubectl and and Helm clients

Install binary versions of both clients and select correct versions for particular ONAP version.

ONAP Helm charts

Clone ONAP Helm charts for specific release including submodules

git clone --branch elalto --recurse-submodules "https://gerrit.onap.org/r/oom"

Change to kubernetes dir
```
cd oom/kubernetes
```
Start Helm service and initialize local Helm repository
```
make repo
```
# This will do same as:
helm serve &
helm repo add local http://127.0.0.1:8879
Package ONAP Helm charts
```
make
```

kubectl -n kube-system create serviceaccount tiller
