• This repo corresponds to the dev env. It is the one that is responsible for building the image and pushing it to Docker Hub: https://hub.docker.com/r/kcandidate/hello
• Once we know that the image works as expected, then we can promote it to prod. In this case, we simply do it by changing the image tag in https://github.com/k-candidate/hello-prod/blob/main/resources/hello-deploy.yaml
• ArgoCD takes care of the deployments for both dev and prod: https://github.com/k-candidate/argocd-demo-install

Demo

To demonstrate, do the following:

• Clone the repo
• Change the version in index.html and resources/hello-deploy.yaml
• Push

git add .
git commit -m "feat: newer version"
git tag v1.0.8
git push origin --tags v1.0.8
git push

• Github Actions will take care of building and pushing the image to Docker Hub.
• ArgoCD will take care of deploying the new version to dev.
• Make sure that all works ok in dev.
• If you deem this version stable, and decide to upgrade prod, then simply change the image tag in https://github.com/k-candidate/hello-prod/blob/main/resources/hello-deploy.yaml and ArgoCD will take care of deploying the new image to prod.

TO DO:

• Use trivy to scan the image for vulnerabilities and upload results to Security tab.
• Add Autoscaling using KEDA.
