curriculum VS k3d

Also check out https://www.cncf.io/certification/cka/. One of the good links in resources is the exam curriculum.

My primary skills revolve around Linux/Docker/Kubernetes, AWS, and automation tools like Gitlab CI, Jenkins, etc. Of course I've picked up a ton of ancillary skills along the way, but these are the core of what I do. So if you do go down that route look at the Kubernetes certs like the CKA, CKAD, and CKS. There are also -JP versions of each of those certs as well, which may be useful in the Japanese market. The CNCF (Cloud Native Computing Foundation) is a great organization to follow in this regard: https://www.cncf.io/certification/training/ - They have other non-Kubernetes certs as well.

Here’s the curriculum for the exam - https://github.com/cncf/curriculum/blob/master/CKAD_Curriculum_v1.23.pdf

It's not in the official CKAD syllabus either and I didn't encounter it the exam. Just my experience though. https://github.com/cncf/curriculum/blob/master/CKAD_Curriculum_v1.22.pdf

If you want some training, take a look at the Linux Foundation and Cloud Native Computing Foundation.

I currently co-lead the documentation efforts for Kubernetes & LitmusChaos, am a CNCF ambassador, have spoken at global events, and have even co-led the creation & review of the KCNA certification. I intend to continue and plan on writing/speaking more about cloud native & open source. My target is to get myself CKA & CKAD certified by Q1, 2022 & continue exploring other avenues of the projects I can contribute to.

I'm preparing for the CKAD exam. I am following the https://github.com/cncf/curriculum/blob/master/CKAD_Curriculum_V1.21.pdf curriculum for my preparation. There is however another one https://github.com/cncf/curriculum/blob/master/CKAD-2021_Curriculum_Coming_Q3_2021.pdf.

K3D: is a lightweight distribution of Kubernetes designed for resource-constrained environments. It is an excellent option for running Kubernetes on virtual machines or cloud servers.

k3d is a lightweight wrapper that makes running Kubernetes (specifically, the lightweight k3s distribution) in Docker straightforward and efficient. It's designed to provide developers with a quick and easy way to test Kubernetes without the overhead of setting up a full cluster.

If you customer prefers to run the standard docker engine you could use k3d

You don’t need to run Rancher from a Kubernetes cluster, the rancher/rancher image works fine with Docker (it uses k3d, aka « k3s in docker » : https://k3d.io/).

K3d and Skaffold for local development

If you are a developer and want to learn how to deploy applications to a cluster, getting a cluster up an running can be a daunting task in it's own rights. There are many ways to do it: spinning up local virtual machines and configuring from scratch or using tools like minikube, etc. You may not care for the pain of setting up and configuring a cluster, and if that is you, then the quickest way that I have found is using k3d.
