Simple Eiffel - Kubernetes et al

[Liberty Lover]

Okay guys,

It's time to address the next step. This is going to finally address the issue Eric brought up about GitHub Actions, et al.

There is now a pair of documents that address both the vision and implementation of simple_k8s.

Enjoy,

Larry

● Great question. Here's my recommendation for dogfooding simple_k8s:

  Primary Target: Simple Eiffel CI/CD Pipeline

  Deploy a self-hosted CI runner cluster on Kubernetes that:

  1. Builds EiffelStudio containers using simple_docker
  2. Orchestrates test jobs using simple_k8s
  3. Reports to simple_oracle for ecosystem health tracking

  ┌─────────────────────────────────────────────────────────┐
  │                   K8s Cluster                           │
  │  ┌─────────────┐  ┌─────────────┐  ┌─────────────┐     │

  │              └──────────┬──────────┘                    │
  │                         │                               │

                            ▼
                 ┌─────────────────────┐
                 │   simple_oracle     │
                 │   (results DB)      │
                 └─────────────────────┘

  Why This Target?

  | Benefit              | Value                                 |
  |----------------------|---------------------------------------|
  | Proves simple_k8s    | Real orchestration workload           |
  | Proves simple_docker | Real container builds                 |
  | Proves simple_ci     | Real pipeline coordination            |
  | Solves real problem  | Currently no automated CI for 71 libs |
  | Visible credibility  | "Built with Simple Eiffel" badge      |

  Secondary Target: Showcase Web App

  Deploy a simple_web application demonstrating the full stack:

  - simple_web → HTTP server
  - simple_docker → Containerized
  - simple_k8s → Deployed with blue/green
  - simple_telemetry → Metrics collection

  Could be the simple_pkg web registry - search/browse packages online.

  Suggested Order

  1. Get K8s cluster (Docker Desktop, minikube, or cloud)
  2. Build simple_k8s (4 weeks)
  3. CI Pipeline MVP - compile 5 libs in parallel pods
  4. Expand to full ecosystem - all 71 libs nightly
  5. Add simple_pkg registry as showcase app

  This gives you a compelling story: "Simple Eiffel libraries are built and tested by Simple Eiffel libraries running on Kubernetes."

And then there is the deployment goal — K8S Infrastructure.

Milestone announcement.

I finally have the Github Actions in the throes of "running" (e.g. beating out the bugs of K8S).

[Liberty Lover]

● Here's how the self-hosted runner setup works:

  The Architecture:

  1. GitHub Actions (on github.com) receives a trigger (push, PR, manual)
  2. GitHub queues the job and looks for a runner tagged [self-hosted, eiffel]
  3. Your local runner (running in a Docker container on Docker Desktop for Windows, orchestrated by Kubernetes) polls GitHub asking
  "Any jobs for me?"
  4. When it gets a job, it:
    - Clones your repo from GitHub
    - Runs the workflow steps
    - Sends logs/results back to GitHub in real-time

  So the flow is:
  GitHub.com                     Your PC (Docker Desktop + K8s)
      │                                    │
      │ "Here's a job"    ───────────────> │ Runner container pulls job
      │                                    │
      │                                    │ Runs: git clone, ec compile, tests
      │                                    │
      │ <─────────────────  Streams logs   │
      │                                    │
      │ Job complete ✓                     │

  The runner is self-hosted meaning YOU provide the compute (your Windows machine with EiffelStudio), but GitHub orchestrates when
  jobs run.

Thank you Eric for continually pushing on this. I would have let it slip off the radar.

Hi Larry,

Did you choose this architecture as a way to exercise simple_docker
and simple_k8s?

Otherwise there is a much simpler solution using the runners hosted
on GitHub (nothing running on your computer).
