Sample Golang Minikube

Recommendations

• use a free tier of Docker Hub for Docker images
• read more on docker, minikube, kubectl, helm

Run

1. Start by cloning the repo

git clone https://github.com/klopjq/go-minikube
# cd go-minikube/app
# GOOS=linux GOARCH=amd64 go build -tags netgo -o server
# cd ..

2. Build the docker file

docker build --no-cache -t USER_ACCOUNT/go-minikube:0.1.1 .

3. Test the container

docker run -d -p 3333:3000 --name go-app-container USER_ACCOUNT/go-minikube:0.1.1

4. Push to docker hub (make sure you login to your own DOCKERHUB USER_ACCOUNT)

docker push USER_ACCOUNT/go-minikube:0.1.1

5. Remove docker images and containers (since the image is already in docker hub)

./clean-docker.sh 
docker images

6. Install minikube (read more from provider website)

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
minikube start
minikube kubectl -- get po -A
minikube dashboard

7. Install kubectl (read more from provider website)

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin/kubectl
kubectl cluster-info
kubectl cluster-info dump
kubectl get nodes
kubectl describe node

8. Install helm (read more from provider website)

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh
helm search hub redis

9. (Optional) Create helm charts if you want to build own, it creates scaffolds

helm create helm

10. Configure the helm (read more from provider website)

11. Install release of helm chart (make sure minikube is started & read more information from provider website)

# helm install RELEASE-NAME ./helm/
helm install go-minikube ./helm/

12. (Optional) Start minikube

minikube start

13. (Optional) Unistall helm release

helm uninstall go-minikube
