José Valim: If you look at the features listed by Kubernetes (#k8s) and compare it to languages that run on the Erlang VM, such as Erlang and Elixir, the impression is that they share many k eywords, such as “self-healing”, “horizontal scaling”, “distribution”, etc.

This sharing often leads to confusion. Do they provide distinct behaviors? Do they overlap? For instance, is there any purpose to #elixir’s fault tolerance if Kubernetes also provides self-healing?

In this article, I will go over many of these topics and show how they are mostly complementary and discuss the rare case where they do overlap.

​​Chaos Mesh is a cloud-native Chaos Engineering platform that orchestrates chaos on #k8s environments. At the current stage, it has the following components:

- Chaos Operator: the core component for chaos orchestration. Fully open sourced.
- Chaos Dashboard: a visualized panel that shows the impacts of chaos experiments on the online services of the system; under development; curently only supports chaos experiments on TiDB(https://github.com/pingcap/tidb).

Skaffold is a command line tool that facilitates continuous development for Kubernetes applications. You can iterate on your application source code locally then deploy to local or remote Kubernetes clusters. Skaffold handles the workflow for building, pushing and deploying your application. It also provides building blocks and describe customizations for a CI/CD pipeline.

arkade (ark for short) provides a clean CLI with strongly-typed flags to install charts and apps to your cluster in one command.

Gone are the days of contending with dozens of README files just to get the right version of #helm and to install a chart with sane defaults.
