Q: What are prerequisites to learning Kubernetes?

📺 https://youtu.be/griUcM_QSdk

A stage approach seems to be materializing from my own struggles to learn the entirety of Kubernetes.

Before you begin any of this you must have proficiency in the following:

• Become an Autodidact
• Linux Bash Command Line
• Git and GitHub for Source Management
• CommonMark Markdown
• Bash Scripting (shellcheck)
• JSON / YAML
• Go Template Language
• Web Essentials (HTML, CSS, Plain JavaScript, DOM, HTTP)
• Networking and Network Troubleshooting
• Using and Creating Containers with docker and Dockerfile
• You can learn docker-compose if you want, then kustomize
• Deep Understanding of x.509 Certificates and openssl

Here’s a quick overview in a prioritized order:

1. Get familiar with Kubernetes component architecture and communication
2. Get familiar with all standard Kubernetes resources
3. Use kind to deploy a simple app
4. Use minikube to deploy a simple app with an exposed service
5. Use kubeadm init to deploy cluster in VirtualBox and app
6. Use kubeadm init to deploy cluster in Docker and app
7. Use kubeadm init phase to deploy cluster one phase at a time and app
8. Deploy single-node cluster in phases “the hard way” (no kubeadm)
9. Use kubeadm to deploy multi-node cluster using cloud provider
10. Deploy multi-node cluster in cloud without kubeadm
11. Use kubeadm to deploy multi-node cluster on-prem on own hardware
12. Deploy multi-node cluster on-prem on own hardware without kubeadm

When you finish all of these 12-steps you’ll easily pass any certification exam and would be immediately able to deploy any Kubernetes flavor for any potential customer or organization.

Keep in mind this does not include all of the extra stuff anyone needs to understand and deploy that comes along with Kubernetes (Istio, Helm, ElasticSearch, Prometheus, Thanos, Sidero, Calico, Nginx, OpenSSL Certificates, etc.)
