Connection test from old Jenkins (2.492.2) to a new Kubernetes cluster failed with io.fabric8.kubernetes.client.KubernetesClientException due to Unrecognized field "emulationMajor"; upgrading the Kubernetes plugin fixed it.

A quick test to see how fast a Kubernetes namespace can be recovered after deletion. Using Velero with an S3 backend on a K3s cluster, a demo application namespace was backed up, deleted, and restored. The restore completed successfully, recreating the Deployment, Pod, and Service within seconds.

Emails to [email protected] are auto-assigned via Power Automate to one active engineer in round-robin, creating a Planner task. SharePoint tracks rotation and conversation IDs to prevent duplicates, ensuring clear ownership and timely responses.

A private K3s node on Proxmox VE is accessed from a public VPS via Tailscale. The VPS joins the mesh, and adding its Tailscale IP to K3s tls-san allows kubectl access without exposing port 6443 publicly.

Installing Jenkins on Kubernetes via Helm worked smoothly at first, but after a node restart, the pod became unhealthy during plugin initialization. The init container attempted to re-copy plugins into an already populated persistent volume, causing overwrite prompts and blocking startup.

Step-by-step guide for exposing ArgoCD on a K3s cluster with Cloudflare full-strict TLS. Includes using a Cloudflare Origin Certificate with NGINX Ingress, disabling Traefik, Helm installation, creating TLS secrets, configuring ArgoCD Ingress.

This write-up outlines a subdomain-to-root migration for a Ghost CMS instance running in Docker behind Cloudflare Tunnel. The approach relies on edge-level 301 redirects, application-level canonical updates, and proper validation to preserve URL structure and search engine signals.
