Developer Tooling for Kubernetes in 2021 – Docker, BuildKit, Buildpacks, Jib and Kaniko (Part 4)

Over the last few blog posts, I've covered critical elements of developer tooling for Kubernetes and how things are looking in 2021. As we continue to dive into that discussion, we must not forget the process of building container images.

Of course, most of us create our images by writing Dockerfiles and building them with the Docker engine. And yet, more and more teams are adopting newer alternatives. After all, the Docker image format has been standardized as part of the OCI (Open Container Initiative) a long while ago.

Simulating Clock Skew in K8s With Chaos Mesh

Chaos Mesh™, an easy-to-use, open-source, cloud-native chaos engineering platform for Kubernetes (K8s), has a new feature, TimeChaos, which simulates the clock skew phenomenon. Usually, when we modify clocks in a container, we want a minimized blast radius, and we don't want the change to affect the other containers on the node. In reality, however, implementing this can be harder than you think. How does Chaos Mesh solve this problem?

In this post, I'll describe how we hacked through different approaches of clock skew and how TimeChaos in Chaos Mesh enables time to swing freely in containers.
