In this sample web application, you will create a web application using Gin to serve web pages in Go, complete with standard best practices, including a health check.

This app contains an opinionated set of files for web serving:

• public/index.html
• public/404.html
• public/500.html

You can deploy this application to IBM Cloud or build it locally by cloning this repo first. Once your app is live, you can access the /health endpoint to build out your cloud native application.

Click Deploy to IBM Cloud to deploy this same application to IBM Cloud. This option creates a deployment pipeline, complete with a hosted GitLab project and a DevOps toolchain. You can deploy your app to Cloud Foundry, a Kubernetes cluster, or a Red Hat OpenShift cluster. OpenShift is available only through a standard cluster, which requires you to have a billable account.

IBM Cloud DevOps services provides toolchains as a set of tool integrations that support development, deployment, and operations tasks inside IBM Cloud.

To get started building this web application locally, you can either run the application natively or use the IBM Cloud Developer Tools for containerization and easy deployment to IBM Cloud.

All of your go dependencies are stored inside of go modules.

• Install Go

In order for Go applications to run locally, the project contents must be placed in the following path:

cd $GOPATH/src/gowebapp

Import dependencies from go modules:

dep ensure

Once the dependencies have been installed, you can compile a Go project with:

go install

To run your application locally:

go run server.go

Your sources will be compiled to your $GOPATH/bin directory. Your application will be running at https://localhost:8080.

Install IBM Cloud Developer Tools on your machine by running the following command:

curl -sL https://ibm.biz/idt-installer | bash

Create an application on IBM Cloud by running:

ibmcloud dev create

This will create and download a starter application with the necessary files needed for local development and deployment.

Your application will be compiled with Docker containers. To compile and run your app, run:

ibmcloud dev build
ibmcloud dev run

This will launch your application locally. When you are ready to deploy to IBM Cloud on Cloud Foundry or Kubernetes, run one of the commands:

ibmcloud dev deploy -t buildpack // to Cloud Foundry
ibmcloud dev deploy -t container // to K8s cluster

You can build and debug your app locally with:

ibmcloud dev build --debug
ibmcloud dev debug
