About
Cloud environments such as Kubernetes and OpenShift benefit from processes different from the ones developers traditionally used for standalone applications. Automation becomes a necessity in large environments and fast-changing configurations of hosts.
Getting GitOps is a practical guide through the jungle of modern development with Kubernetes, with a focus on application distribution via continuous integration/continuous delivery (CI/CD) and GitOps on Red Hat OpenShift. It starts by defining a common use case and taking you through it from beginning to end.
This book covers:
- How to install and use Quarkus for Java development
- How to configure an application to use a PostgreSQL database in a Kubernetes environment
- Basic Kubernetes files
- OpenShift Templates
- The Kustomize configuration management tool
- The Docker, Podman, Buildah, and Skopeo build tools
- Basic Helm charts and subcharts
- Kubernetes Operators
- CI/CD with Tekton
- CI/CD with OpenShift Pipelines
- GitOps with Argo CD
- Tekton security
Excerpt
Each application you’re deploying on Kubernetes has a bunch of YAML files that are required to run your application. Adding those files to your project in a Git repository is just a natural step forward. And if you had a tool that could read those files from the repository and apply them to a specified Kubernetes namespace, wouldn’t that be great?
Well, that’s what GitOps accomplishes. And Argo CD is one of the available tools to help you do GitOps.
