IBM Fundamentals: Get Started Go

From Zero to Go: A Deep Dive into IBM's "Get Started Go" Service

Imagine you're a financial services company, heavily regulated and needing to rapidly deploy a new microservice for fraud detection. You're facing mounting pressure to innovate, but your existing infrastructure is complex, security concerns are paramount, and developer velocity is slow. Or perhaps you're a healthcare provider aiming to build a patient data analytics platform, requiring strict HIPAA compliance and seamless integration with existing Electronic Health Record (EHR) systems. These are the kinds of challenges modern businesses face daily. IBM understands these pressures. In fact, a recent IBM study showed that 77% of organizations struggle with the complexity of modern application development and deployment. This is where IBM’s “Get Started Go” service comes into play. It’s designed to accelerate your journey to cloud-native applications, providing a streamlined, secure, and compliant environment for building and deploying Go-based applications. The rise of cloud-native architectures, coupled with the increasing need for zero-trust security and hybrid identity management, demands solutions like Get Started Go to simplify the process and reduce risk.

What is "Get Started Go"?

"Get Started Go" is a fully managed service on IBM Cloud designed to simplify the development, deployment, and management of Go applications. Think of it as a pre-configured, optimized environment specifically tailored for Go developers. It removes the operational overhead of managing infrastructure, allowing you to focus solely on writing code.

At its core, Get Started Go solves the problems of:

• Infrastructure Management: No more worrying about servers, networking, or operating system updates.
• Dependency Management: Pre-configured with essential Go dependencies and tools.

Hands-On: Step-by-Step Tutorial

Let's deploy a simple "Hello, World!" Go application using the IBM Cloud CLI.

Prerequisites:

• IBM Cloud account
• IBM Cloud CLI installed and configured
• Go installed locally

Steps:

1. Login to IBM Cloud: ibmcloud login
2. Create a Kubernetes Cluster: ibmcloud ks create --name my-go-cluster --zone us-south --workers 3 (Adjust zone and worker count as needed)
3. Set the Kubernetes Context: ibmcloud ks cluster config my-go-cluster
4. Create a Dockerfile:

   FROM golang:1.21-alpine
   WORKDIR /app
   COPY main.go .
   RUN go build -o main .
   CMD ["./main"]

1. Create a main.go file:

   package main

   import "fmt"

   func main() {
       fmt.Println("Hello, World!")
   }

1. Build and Push the Docker Image:

   docker build -t us.icr.io/your-namespace/hello-go .
   docker push us.icr.io/your-namespace/hello-go

(Replace your-namespace with your IBM Cloud container registry namespace)

1. Deploy the Application:

   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: hello-go-deployment
   spec:
     replicas: 2
     selector:
       matchLabels:
         app: hello-go
     template:
       metadata:
         labels:
