The golang-ex repository is a sample Golang web application designed for OpenShift v3 that demonstrates how to deploy a Go-based service using the beego framework. The application is built on the official Docker golang image without requiring any modifications to the base image or the sample code itself. This repository serves as a practical example for developers looking to containerize and deploy Go applications on OpenShift, Red Hat's Kubernetes-based container platform.
The repository was originally copied from the official beego samples repository and adapted specifically for OpenShift deployments. It showcases the integration of Go applications with OpenShift's source-to-image build process, which automates the building and deployment of containerized applications directly from source code repositories. The example demonstrates how to leverage OpenShift's templating system through a beego.json template file that streamlines the application deployment process.
Installation of the golang-ex application requires users to fork the repository, clone it locally, and then use OpenShift's command-line tool to create a new application from the beego template. The deployment process involves specifying a source repository URL and allowing OpenShift to automatically trigger builds. Users can monitor build progress through OpenShift's command-line interface using the oc get builds and oc logs commands. Once the build completes and the pod starts running, the application becomes accessible through OpenShift's routing system, which provides DNS-based access to the deployed service.
The repository includes detailed instructions for accessing the deployed application, including guidance on configuring local DNS resolution through the /etc/hosts file for development environments. The application runs on port 8080 and can be accessed either through the OpenShift web console or by directly querying service information using OpenShift CLI commands. The documentation provides sample output from these commands to help users understand what to expect during the deployment process.
The golang-ex repository is classified across multiple technical domains including Golang, example applications, Docker, Kubernetes, container deployment, web servers, cloud platforms, source-to-image technology, OpenShift, and REST APIs. This broad classification reflects the repository's role as a comprehensive example that touches on multiple aspects of containerized application deployment and cloud-native development practices.
The code is dedicated to the public domain under the CC0 license to the maximum extent permitted by applicable law, while the underlying beego sample application code follows the Apache License. This dual licensing approach allows developers to freely use and modify the example code while respecting the original beego framework's licensing terms. The repository serves as an educational resource for developers learning to deploy Go applications on OpenShift and understanding the integration between Go web frameworks and container orchestration platforms.
