The SRE's Quick Guide to Kubectl Logs

Logs are key to monitoring the performance of your applications. Kubernetes offers a command line tool for interacting with the control plane of a Kubernetes cluster called Kubectl. This tool allows debugging, monitoring, and, most importantly, logging capabilities. There are many great tools for SREs. However, Kubernetes supports Site Reliability Engineering principles through its capacity to standardize the definition, architecture, and orchestration of containerized applications.

Ephemeral Environments: Explained, Benefits, and How to Get Started?

Ephemeral environments are getting popular among companies that need to scale their business efficiently.

Stop Using TCP Health Checks for Kubernetes Applications

As developers, one of the most important things we can consider when designing and building applications is the ability to know if our application is running in an ideal operating condition, or said another way: the ability to know whether or not your application is healthy. This is particularly important when deploying your application to Kubernetes. Kubernetes has the concept of container probes that, when used, can help ensure the health and availability of your application.

What is Kubernetes CrashLoopBackOff? And how to fix it

CrashLoopBackOff is a Kubernetes state representing a restart loop that is happening in a Pod: a container in the Pod is started, but crashes and is then restarted, over and over again. Kubernetes will wait an increasing back-off time between restarts to give you a chance to fix the error. As such, CrashLoopBackOff is not an error on itself, but indicates that there’s an error happening that prevents a Pod from starting properly.
