Deploying Go Apps with Kubernetes
- Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications.
- In this tutorial, we are going to create a Go application and prepare it to run inside a Kubernetes cluster.
- Containers have been widely adopted by most industries, and one of the most popular containerization tools is Docker. However, as complexity grew, people started looking for orchestration tools that were effective at scale, performed load balancing, self-healed, and more. There were many contenders in the competition, like Apache Mesos, HashiCorp Nomad, and Docker Swarm, but Kubernetes has thrived for a long time due to its robust ecosystem, extensive community support, scalability, and ability to manage complex, distributed applications across multiple environments.
- The process of deploying applications to servers has changed drastically over the years, from physically traveling to a data center, to deploying to VMs, and now to containers and orchestration tools like Kubernetes.
- In this tutorial, the author explains how to write a Go application from scratch and deploy it to a local Kubernetes cluster. They cover creating a basic Go application, installing packages, building core business functions, setting up an HTTP server, creating HTTP handlers, creating a Dockerfile, writing Kubernetes manifests, and testing.
- Apart from Go, the author also covers using other tools such as Gorilla Mux, GORM, and Docker Desktop to help deploy and manage the Kubernetes cluster.
- The author also explains how to create a Dockerfile, a PersistentVolume (PV), a PersistentVolumeClaim (PVC), and a ConfigMap in Kubernetes to manage and orchestrate the deployment of apps.
- Overall, this tutorial provides a detailed guide on deploying Go apps using Kubernetes, explaining each step carefully and providing additional resources for those interested in further exploration.
- The article mentions how Kubernetes is one of the largest open-source projects to date, boasting more than 88,000 contributors.
- The tutorial also covers how to deploy the app to a live cluster by redirecting users to an article by the author for deploying Go apps in Google Kubernetes Engine.
