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.

Local Kubernetes development with no stress.

Tilt helps you develop your microservices locally. Run tilt up to start working on your services in a complete dev environment configured for your team.

Tilt watches your files for edits, automatically builds your container images, and applies any changes to bring your environment up-to-date in real-time. Think docker build && kubectl apply or docker-compose up.

Lightweight Kubernetes. Easy to install, half the memory, all in a binary less than 40mb.

Great for:
- Edge
- IoT
- CI
- ARM
- Situations where a PhD in #k8s clusterology is infeasible

​​Gitpod is an open-source #k8s application providing fully-baked, collaborative development environments in your browser - powered by VS Code.

Tightly integrated with GitLab, GitHub, and Bitbucket, Gitpod automatically and continuously prebuilds dev environments for all your branches. As a result, team members can instantly start coding with fresh, ephemeral and fully-compiled dev environments - no matter if you are building a new feature, want to fix a bug or do a code review.

Features:
- Dev environment as code
- Prebuilt dev environments - automatically prepare environments on every Git push
- Professional developer experience in a browser tab (VS Code Extensions, full Linux terminals)
- Integrated Docker build
- GitLab, GitHub, and Bitbucket integration
- Integrated code reviews
- Snapshots - Snapshot any state of your dev environment and let others create clones
- Collaboration - Invite team members to your environments
- Gitpod CLI to automate your experience

​​Litmus helps Kubernetes SREs and developers practice chaos engineering in a Kubernetes native way.

Litmus is a toolset to do cloud-native chaos engineering. Litmus provides tools to orchestrate chaos on #k8s to help SREs find weaknesses in their deployments. SREs use Litmus to run chaos experiments initially in the staging environment and eventually in production to find bugs, vulnerabilities. Fixing the weaknesses leads to increased resilience of the system.

Litmus takes a cloud-native approach to create, manage and monitor chaos. Chaos is orchestrated using the following Kubernetes Custom Resource Definitions (CRDs):
- ChaosEngine: A resource to link a Kubernetes application or Kubernetes node to a ChaosExperiment. ChaosEngine is watched by Litmus' Chaos-Operator which then invokes Chaos-Experiments
- ChaosExperiment: A resource to group the configuration parameters of a chaos experiment. ChaosExperiment CRs are created by the operator when experiments are invoked by ChaosEngine.
- ChaosResult: A resource to hold the results of a chaos-experiment. The Chaos-exporter reads the results and exports the metrics into a configured Prometheus server.

Chaos experiments are hosted on hub.litmuschaos.io. It is a central hub where the application developers or vendors share their chaos experiments so that their users can use them to increase the resilience of the applications in production.
