Containerization with Kubernetes Workshop

Dev Tools

• VS Code

• Recommended for Windows:

  • Windows Terminal

    • https://github.com/microsoft/terminal#installing-and-running-windows-terminal

  • Windows Subsystem for Linux (WSL2) if permitted

    • https://docs.microsoft.com/en-us/windows/wsl/about

  • Package Managers such as winget or scoop if permitted (makes it easier to install CLI tools on Windows)

  • Preferred Shell of your choice: PowerShell Core (pwsh), GitBash, WSL2 Bash/ZSH, etc.

• CLI Tools:

  • Git
  • Azure CLI
  • Kubectl
  • Kustomize
  • Helm
  • Curl or Httpie

Docker Desktop

1. Install Docker Desktop in your development environment

• https://www.docker.com/products/docker-desktop

Make Sure Kubernetes is enabled,

If you're using WSL2, don't forget to enable it toset limits as shown below: (also you need to integrate docker with your wsl2 distro (see Resources option)

• https://docs.microsoft.com/en-us/windows/wsl/wsl-config#configure-global-options-with-wslconfig

Local Kubernetes

1. Getting Started with Docker Desktop Kubernetes

• Test connection to your cluster from terminal

  • kubectl cluster-info
  • kubectl get nodes

---

2. Setup your default namespace.

• Create your first namespace

  only use lower-case letters and dashes

    # for example, john or jane
    kubectl create namespace <your-firstname> 
    
    # use your own namespace as a default 
    kubectl config set-context --current --namespace=<your-namespace-name>

    # test it. below should return `No resources found in <your-namespace>`
    kubectl get pods    

---

3. Setup your workspace / project directory for docker and k8s labs

• Create a directory in your local environment to do the labs. (for e.g: cw_labs)

• For e.g, below would create cw_labs directory in your user_home

  # run this from powershell, bash, gitbash, etc. depending on your local setup
  # feel free to change the location and name as you prefer
  mkdir ~/cw_labs

• Create Docker and Kubernetes directories with in your project_directory

• Your setup should looks somethign like below.

  ├── cw_labs
      ├── docker              
      └── kubernetes

Keep this repo link open in a separate tab or window: https://github.com/suren-m/cw/tree/master/labs and use it as a source of truth for upto date content.

Labs

Take a look at Labs directory to get started with the labs for 01_Docker and then move on to 02_kubernetes.

Recommended:

• At least do until 04_docker_registry.md lab before moving on to kubernetes.
• In Kubernetes, do at least till 04_deployments.md before moving on to creating your own cluster.

---

AKS (for those with MSDN subscription or azure dev/sandbox environment)

• If you have MSDN subscription and like to create and connect to AKS, see 04_aks_cluster in labs directory.

If you're new to K8s, it is recommended to first familiarize yourself on local cluster a bit by doing a few of the labs from 01_docker and 02_kubernetes before moving to AKS. (perhaps on day/week 2)

• By all means, feel free to create it anytime if you don't have local kubernetes available.
