CHANGELOG

2025-09-24¶

Add the K3s Monitoring page to describe how to deploy a complete monitoring stack in a single-node K3s cluster using Helm charts. The stack includes Prometheus for metrics, Grafana Loki for logs, Grafana Tempo for traces, and Grafana for visualization. I also deployed the OpenTelemetry Collector to receive telemetry data from applications, and showed how to configure a demo application to send logs and traces using the OTLP protocol.

Add the K3s Index page to describe my first steps with K3s, including how to install it, deploy a simple web application that uses a Persistent Volume, and expose it using Traefik.
Add the K3s Ingress Per App page to describe how to expose multiple web applications on different domains using K3s and Traefik.

Add the CloudNativePG page to describe my first baby steps with CloudNativePG, including a brief introduction to Operators and how they extend Kubernetes capabilities to manage complex applications like databases.
Improve the mounting volumes example to use the /home/stores/ folder on the host machine, instead of a user-specific home folder.

Improve the PostgreSQL page to describe how to connect to a PostgreSQL server running in Kind using a Load Balancer, from a Docker container that is not part of the Kubernetes cluster (e.g. to use psql or pgAdmin from a standalone Docker container).

Improve the Getting Started page to include information about more Kubernetes distributions: Minikube, MicroK8s, Kubeadm, Kind, K3s, at Other Kubernetes Distributions.
Add an exercise about running a single PostgreSQL Server in plain Docker and in Kubernetes, for local development.

Add Kind Multi Nodes example and notes.
Add a CHANGELOG.
Improve the Mounting a Volume example to include information about PersistentVolume vs hostPath.
Improve the Web Hosting example to describe the kubectl create secret … command
