Simplest k8s deployment as described in this article https://itnext.io/simplest-minimal-k8s-app-tutorial-with-rancher-desktop-in-5-min-5481edb9a4a5

The declarative yaml manifests in this repo are:

• jade-shooter-deployment.yaml: deploys a scalable deployment of a simple app which creates a scalable number of K8s pods which respond to port 80 and encapsulate a container
• jade-shooter-service.yaml: creates a service that allows this webapp's port 80 to communicate outside of its K8s namespace (AKA dedicated secure cluster) via port 8080
• jade-shooter-ingress.yaml: creates an ingress that exposes the service to requests outside of the K8s cluster at https://jade-shooter.rancher.localhost

Usage

1. Install Rancher Desktop https://rancherdesktop.io/, the easiest way to get a local K8s lab imo. Here's how I set mine up: https://medium.com/macoclock/rancher-desktop-setup-for-k8s-on-your-macos-laptop-6f1c576ceb48

2. Clone this repo

   git clone https://github.com/jwsy/simplest-k8s.git
   

3. Apply the manifests in this repo

   cd simplest-k8s/
   kubectl apply -f .

4. Browse to https://jade-shooter.rancher.localhost

Notes

• The app is this customizable Kaboom space shooter created in this article: https://javascript.plainenglish.io/kaboom-js-repl-it-custom-top-down-shooter-in-5-min-ebad8157073a?postPublishedType=repub
