This project consists of the smallest possible application to demo cloud native application delivery. It - for sure - will grow over time. Right now you get the following components:

• A single file go server that displays different versions of the podtato-head depending on the version

• A multi-stage build docker file to build a container

• A manifest to create a Kubernetes service and deployment.

• A helm chart for the service and the deployment.

• Three container images showing different versions

  • ghcr.io/podtato-head/podtatoserver:v0.1.0
  • ghcr.io/podtato-head/podtatoserver:v0.1.1
  • ghcr.io/podtato-head/podtatoserver:v0.1.2

This list is supposed to grow over time. Here is the list of use cases, that are currently supported:

• Direct deployment via a manifest
• Direct deployment via a Helm chart
• Direct deployment via Kustomize
• Direct deployment via Kapp
• GitOps-based deployment using Flux
• GitOps-based deployment using ArgoCd
• Canary releases via Argo Rollouts
• Helm-based operator deployment
• Multi-Stage delivery with Keptn
• CNAB with Porter air-gapped deployment
• GitOps-based deployment using KubeVella
• GitOps-based deployment using Gimlet CLI

Use cases supported going foward:

• multiple services in different version
• stateful workloads
• external dependencies
• feel free to create issues for use cases you are interested in

You can use any K8S cluster to run this project. If you do not have a K8S cluster at your disposal, you can quickly get a local one with kind.

NOTE: If you use a cluster with no access to external LoadBalancer (like a kind cluster), you may have to replace type: LoadBalancer by type: ClusterIP (or type: NodePort) in all service.yaml manifests :

find delivery -type f -name "*.yaml" -print0 | xargs -0 sed -i 's/type: LoadBalancer/type: ClusterIP/g'
