CHANGELOG

2025-10-26

• Improve the Monitoring exercise to include improved monitoring using the kube-prometheus-stack Helm chart for Prometheus and Grafana.
• Add the CloudNativePG exercise where I share my notes on using CloudNative-PG in K3s, how to configure monitoring and backups with an Azure Storage Account.

2025-10-03

• Add the Azure Container Registry exercise that describes how to pull images from an Azure Container Registry to a Kubernetes cluster running on-premises, using RBAC and following the principle of least privilege (pull access only).

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.

2025-08-09

• 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.

2025-08-02

• 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).

2025-07-30

• 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.

2025-07-27

• Add Kind Multi Nodes example and notes.
• Add a CHANGELOG.
