For the next ~1h 30m we'll be looking at managing applications with Kubernetes.

This is a hands-on type of workshop. You are invited to follow along as the presenter goes through the prepared content.

Before we begin, please prepare your workstation:

1. Open https://github.com/cbalan/k101
2. Open https://www.katacoda.com/courses/kubernetes/playground and click "Start Scenario".
3. On the master node, clone this repository. All code samples paths are relative to this repository root.

git clone https://github.com/cbalan/k101 && cd k101

4. Confirm that the cluster is ready using the following command:

kubectl cluster-info

At any moment during the workshop, if you have any questions, please let the organizers know.

• Kubernetes overview
• Deep dive into
  • Pods
  • Deployments
  • Services
• From Git to Kubernetes exercise

All samples assume that the audience already has access to a kubernetes cluster.

To keep things simple, the following browser based Katacoda playground can be used: https://www.katacoda.com/courses/kubernetes/playground

Alternatively, the following tools can be used:

• Git
• Your favorite text editor
• Docker: https://www.docker.com
• Kind-0.7.0: https://kind.sigs.k8s.io/docs/user/quick-start
• Kubectl-1.17.0: https://kubernetes.io/docs/tasks/tools/install-kubectl

Some of these may or may not be obvious:

• manifests - All Kubernetes api objects are defined via YAML format
• k8s, kube - shortcuts, references to the Kubernetes project
• kube control, kube C T L, "kube cuddle" - reference to kubectl command line
• SIG - Special Interest Group. Kubernetes SIG list available here: https://github.com/kubernetes/community/blob/master/sig-list.md

This workshop is barely scratching the surface. Please refer to https://kubernetes.io/docs/concepts/ for advanced topics like security, storage, networking and cluster administration.
