Datadog operates large-scale Kubernetes clusters in production across multiple clouds. Along the way, audit logs have been extremely helpful for tracking user interactions with the API server, debugging issues, and getting clarity into our workloads. In this post, we’ll show you how to leverage the power of Kubernetes audit logs to get deep insight into your clusters.

Kubernetes events are a resource type in Kubernetes that are automatically created when other resources have state changes, errors, or other messages that should be broadcast to the system. While there is not a lot of documentation available for events, they are an invaluable resource when debugging issues in your Kubernetes cluster. In this post we will learn how to look at events, learn about a few specific event types, and discuss how to monitor Kubernetes events.

What do a test engineer and a DevOps or SRE team member have in common?

I’d like to take a moment to point out some of my favorite things that have come across my Twitter timeline in the last week, if you’d like to see more follow Stackery on twitter!

In our previous blog post we discussed the challenges with relying on external servers for downloading pre-build tools such as Curl, CLI, wget, Maven, Gradle, npm and others. We discussed how they can sometimes cause stability issues, also called “Environmental Issues”, that will break the build.

Monitoring your application from end to end is important for ensuring that core functionalities work as designed.

Within these workflows, email often plays a key role in onboarding users and providing customers with important information about their accounts and application activity, such as profile changes and order confirmations.
