📨🚚 CNCF App Delivery SIG Demo

Project pod tato Head - A demo project for showcasing cloud-native application delivery use cases using different tools for various use cases

What you are getting

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

Scenarios and Use Cases you can test with this repository

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 Ketch
• 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

Cluster environment

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'
