In this six-part tutorial you will be deploy, explore, scale, and perform a rolling update on an app deployed on Kubernetes. Each section of the tutorial includes a single page of text describing Kubernetes objects (akin to a lecture) and a short interactive tutorial (lab).

If you have never touched Kubernetes before, this is a good place to start; if you have some experience with Kubernetes, you can safely skip this tutorial.

During this brief interactive tutorial you will start a minikube cluster (single node Kubernetes cluster for local testing/learning), use kubectl commands to imperatively create Kubernetes objects (Deployments, Replication Controllers, and Services) and examine details about each object using the get and describe subcommands. Finally, you will scale your deployed application and connect to it using curl against its service IP.

This interactive tutorial introduces the use of YAML in Kubernetes and illustrates the best practice of using declarative means to create and manage objects. You will use kubectl to create and launch Deployments and expose them via Services written in YAML.

This tutorial introduces Kubernetes namespaces and commands to run pods in specific namespaces. Lightweight introductions of labels and volumes are included and the Kubernetes API documentation is reviewed. We recommend skipping the somewhat outdated challenge at the end of the module.

This tutorial Introduces all of the Kubernetes service types and their use. Each type is pre-created for you, though you can explore the service manifests during the tutorial with standard Linux tools. Each service is created using declarative means, reinforcing best practice.

This tutorial explores the Kubernetes daemonset controller, explaining what daemonsets are typically used for and how daemonset-managed pods behave in a cluster.

Node taints and the kubectl replace command, used to update resources on the fly, are also discussed.

This tutorial discusses the various ways pod scheduling is influenced through the use of labels, nodeSelectors, and node and pod affinity and anti-affinity.

The first part of this tutorial introduces bootstrapping a two-node Kubernetes cluster using the kubeadm tool; it covers kubeadm init to instantiate a cluster and kubeadm join to add a worker node. It completes the cluster by illustrating the application of a CNI software-defined networking plugin.

The second part of the tutorial discusses Kubernetes security and identity features related to ServiceAccounts and role-based access control (RBAC)

The Linux Foundation's free LFS158 course provides an introduction to Kubernetes over 16 chapters that are upwards of 12 hours of e-learning. Since not all of the LFS158 material is relevant for the CKA, we have curated a list of chapters to review.

Plan for each chapter to take approximately 45 minutes

    Ch. 4 - Kubernetes Architecture (explains basic Kubernetes cluster composition)

    Ch. 7 - Access Minikube (relevant because it touches on cluster access with kubectl)

    Ch. 8 - Kubernetes Building Blocks (explains basic Kubernetes resources and tools)

    Ch. 10 - Services (another important building block, especially for controller-backed pods)

    Ch. 11 - Deploying a Stand-Alone application (demonstrates the basic Kubernetes use case in action)

Additional chapters are worth reviewing only if time permits. Access the free course here: https://training.linuxfoundation.org/training/introduction-to-kubernetes/

The first half of the tutorial examines Kubernetes job and cronjob controllers; premade manifests are used to deploy each type and once deployed, their behavior is explored.

In the second half of the tutorial you will explore Kubernetes init containers, examining a pod manifest using an init container and a shared volume.
