It explains how templated image builds streamline deployments, improve reliability, and maintain consistent observability stacks. You will also learn how Prometheus is deployed as a Docker container and begins scraping metrics from both the node and prometheus itself, immediately after launch. The post emphasizes best practices for operational efficiency and repeatability, helping readers to adopt production-grade image automation with confidence. By following the steps, users gain practical insights into building optimized, monitoring-ready infrastructure using Packer in a real-world AWS scenario. https://stalin.thetinkerer.dev/post/automate-uptime-kuma-monitors-with-autokuma-and-docker-labels/ Fri, 17 Oct 2025 15:00:33 +0000 https://stalin.thetinkerer.dev/post/automate-uptime-kuma-monitors-with-autokuma-and-docker-labels/ AutoKuma is a lightweight automation tool that works with Uptime Kuma to automatically create and manage monitors for your Docker containers. It listens to Docker events and reads container labels to decide what services to monitor. By mounting the Docker socket, AutoKuma can detect container changes in real time and update Uptime Kuma accordingly. This eliminates the need to manually add or remove monitors whenever new containers are deployed. You can easily set it up using Docker Compose alongside Uptime Kuma. It’s a great way to simplify monitoring for homelab or DevOps environments where containers frequently change. https://stalin.thetinkerer.dev/post/configure-uptime-kuma-telegram-slack-notifications/ Wed, 08 Oct 2025 22:00:33 +0000 https://stalin.thetinkerer.dev/post/configure-uptime-kuma-telegram-slack-notifications/ Uptime Kuma is a self-hosted monitoring tool that tracks the uptime of websites, services, and servers in real time.
