Google Kubernetes Engine (GKE) is a managed Kubernetes service that simplifies deploying, managing, and scaling containerized applications. In this guide, you'll learn how to build a Go application for GKE. We'll cover setting up a development environment, creating a Go application, containerizing it, deploying to GKE, and provide sample code for each step.


Before getting started, make sure you have Go installed, a Google Cloud account, and the Google Cloud SDK (gcloud) installed on your system. You should also be familiar with basic Go programming and containerization concepts.

Setting Up a Development Environment

To begin building your Go application for GKE, you'll need to set up your development environment. Here's a summary of the steps:

  1. Install Go: If you haven't already, download and install Go from the official website.
  2. Install Docker: Install Docker to create container images for your application.
  3. Set Up Google Cloud SDK: Install the Google Cloud SDK (gcloud) and authenticate your account with 'gcloud auth login'.

Creating a Go Application

Develop your Go application as per your requirements. Ensure it listens to the correct ports and responds to HTTP requests if needed. Here's a simple Go HTTP server as an example:

package main
import (
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
fmt.Fprint(w, "Hello, World!")
http.ListenAndServe(":8080", nil)

Containerizing Your Go Application

To deploy your Go application on GKE, you'll need to containerize it. Create a Dockerfile for your application that specifies how to build the container image. Here's a simple Dockerfile for the Go HTTP server mentioned earlier:

FROM golang:latest
COPY . .
RUN go build -o app
CMD ["./app"]

Deploying to Google Kubernetes Engine

Deploy your containerized Go application to GKE using the following steps:

  1. Create a GKE Cluster: Use 'gcloud container clusters create' to create a GKE cluster.
  2. Authenticate with GKE Cluster: Authenticate kubectl with your cluster using 'gcloud container clusters get-credentials'.
  3. Deploy Your Application: Use kubectl to apply your application's deployment and service configuration files.

Sample Code

Here's a simplified example of a Go HTTP server and a Dockerfile to containerize it. You can adapt this code to your application's needs and create a Kubernetes deployment configuration for deployment.


Building a Go application for Google Kubernetes Engine (GKE) allows you to take advantage of Kubernetes' power for container orchestration. This guide covered setting up a development environment, creating a Go application, containerizing it, deploying to GKE, and provided sample code. With this knowledge, you can effectively build and deploy Go applications on GKE.
