In this tutorial, we will learn about Docker container lifecycle. But first, let me share a personal anecdote.

Docker containers are transient (lasting for a very short time), spawning quickly and in high numbers, which causes metrics bursts. This makes monitoring a challenge due to Docker's scaling and redeployment features. Docker stats is a built-in feature of Docker containers. The
docker stats command returns a live data stream of your running containers.
Kubectl Top command can be used to retrieve snapshots of resource utilization of pods or nodes in your Kubernetes cluster. Resource utilization is an important thing to monitor for Kubernetes cluster owners. In order to monitor resource utilization, you can keep track of things like CPU, memory, and storage.
Kubernetes monitoring is a critical process for keeping your Kubernetes clusters running in fine health. In this tutorial, we will learn everything about Kubernetes monitoring. We will be using two open-source tools: OpenTelemetry and SigNoz, to monitor a Kubernetes cluster, so you can follow along with the tutorial easily.
Celery worker is a simple, flexible, and reliable distributed system to process vast amounts of messages while providing operations with the tools required to maintain such a system. In this tutorial, we will learn how to implement Celery with Flask and Redis.
