Setup local Kubernetes

Docker Desktop

Installing local Kubernetes cluster with docker desktop is the preferred method in this tutorial as it is very easy and comes with kubectl CLI.

If you have not installed kubernetes from docker-desktop before:

To enable Kubernetes in Docker Desktop:

• 1: Open the GUI
• 2: Click on the gear icon in the upper right corner
• 3: Click on the "Enable Kubernetes" toggle. Just leave everything as default.
• 4: Click "Apply & Restart" in the lower right corner.
• 5: Wait until it says "Running" under "Cluster"
• 6: Open a new terminal and check that you are able to run kubectl version

Expected output for kubectl version is

Client Version: v<your-version>
Kustomize Version: v<your-version>
Server Version: v<your-version>

If you have kubectl previously installed it is nice to verify that you are doing this tutorial in docker desktop and not on your production cluster with

kubectl config use-context docker-desktop

Build docker images

Go to app/frontend directory To build docker image run

docker build -t blog-frontend:0.1 .

Go to app/api directory. Build docker image with

docker build -t blog-api:0.1 .

Go to app/image-job

docker build -t image-job:0.1 .

If you do not have problems with the above setup, you do not have to read the rest

Debug: Install kubectl manually

If you cant run kubectl after enabling Kubernetes in Docker Desktop, you can try installing it manually through: https://kubernetes.io/docs/tasks/tools/#kubectl

It is also available through homebrew (mac): brew install kubectl
