## Some tunning ### Upgrade minikube CPUs and Memorybash VBoxManage showvminfo minikube VBoxManage controlvm minikube poweroff VBoxManage modifyvm minikube –cpus 4 VBoxManage modifyvm minikube –memory “16384”
### Starting minikubebash VBoxManage controlvm minikube poweron
### Network configuration forward all this port to the VM and kubernetesbash for port in {30000..32767}; do VBoxManage controlvm minikube natpf1 “NodePort$port,tcp,,$port,,$port”; done
### Get docker environmentbash root:xavier/ # minikube docker-env [13:40:12] export DOCKER_TLS_VERIFY=“1” export DOCKER_HOST=“tcp://192.168.99.100:2376” export DOCKER_CERT_PATH=“/root/.minikube/certs” export DOCKER_API_VERSION=“1.35”
Run this command to configure your shell:
eval $(minikube docker-env)
Let’s run the docker-env command.bash eval $(minikube docker-env)
Look into itbash

### Setup Kubernetes dashboard on minikube
bash root:xavier/ # minikube dashboard –url & [1] 17085 root:xavier/ # Enabling dashboard … Verifying dashboard health … Launching proxy … Verifying proxy health … http://127.0.0.1:46597/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/
Using ssh to forward the dashboard
bash (host machine) $ ssh -L 8081:localhost:46597 xavier@10.0.0.154 surf to http://localhost:8081
### Setup Helm on minikube
bash curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get > get_helm.sh chmod 700 get_helm.sh ./get_helm.sh ````
Run helm
root:xavier/ # helm init [14:12:43]
$HELM_HOME has been configured at /root/.helm.
Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.
Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.
To prevent this, run `helm init` with the --tiller-tls-verify flag.
For more information on securing your installation see: https://docs.helm.sh/using_helm/#securing-your-helm-installation
Happy Helming!
