kubernetes-go-project

Simple Kubernetes Go project with minikube

1. Create a new directory for your project:

mkdir kubernetes-go-project
cd kubernetes-go-project

2. Initialize a new Go module:

go mod init github.com/<username>/kubernetes-go-project

3. Create a new Go file with some code. For example, create a file called main.go with the following content:

package main

import (
    "fmt"
    "net/http"
)

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello, Kubernetes!")
    })

    http.ListenAndServe(":8080", nil)
}

4. Create a Dockerfile in the same directory with the following content:

FROM golang:1.16-alpine

WORKDIR /app

COPY . .

RUN go build -o app .

CMD ["/app/app"]

5. Create a Kubernetes deployment YAML file with the following content. This YAML file will create a deployment with one replica and a service for the deployment.

*Replace your-docker-username with your Docker Hub username.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: kubernetes-go-project
spec:
  replicas: 1
  selector:
    matchLabels:
      app: kubernetes-go-project
  template:
    metadata:
      labels:
        app: kubernetes-go-project
    spec:
      containers:
      - name: kubernetes-go-project
        image: <your-docker-username>/kubernetes-go-project:latest
        ports:
        - containerPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: kubernetes-go-project
spec:
  selector:
    app: kubernetes-go-project
  ports:
    - name: http
      port: 80
      targetPort: 8080

6. Build the Docker image:

docker build -t <your-docker-username>/kubernetes-go-project:latest .

7. and push it to Docker Hub:

docker push <your-docker-username>/kubernetes-go-project:latest

8. Start minikube and deploy the application to Kubernetes by applying the YAML file:

kubectl apply -f deployment.yaml

9. Check the status of your service:

kubectl get services

10. run the following command to access the application:

minikube service kubernetes-go-project
