This repository showcases a use case deployment of a sample Spring boot application right from Git source to local Kubernetes cluster (Docker Desktop) using the following:
Tanzu Build Service - used to automatically trigger a build on code commit which in turn uses CNB (Cloud Native Buildpacks) to create a docker image from the source code and push it to DockerHub. Refer here for installation instructions.
Kustomize - used to create separate deployment configuration for development and production environments.
Argocd - Declarative gitops tool that keeps the kubernetes deployment in sync with the ops repository which contains the Kubernetes manifest files. Refer here for installation instructions
The following diagram illustrates the solution implemented using the above tools:
Modify the dockerhub-credentails.yaml to include a base64 encoded string of Docker config.json file. Add valid Github credentials to github-credentials.yaml. Modify image.yaml to include the Github repository URL and Docker Image registry.
To deploy locally, run the following for creating the TBS resource definition:
kubectl create -f project.yaml -f dockerhub-credentails.yaml -f github-credentials.yaml -f service-account.yaml -f image.yaml
Create an application in ArgoCD and configure the path to one of the overlays folder.
