Setup K8S single node with docker desktop and Helm
Docker Desktop includes a standalone Kubernetes server and client, as well as Docker CLI integration. The Kubernetes server runs locally within your Docker instance, is not configurable, and is a single-node cluster.
The Kubernetes server runs within a Docker container on your local system, and is only for local testing. When Kubernetes support is enabled, you can deploy your workloads, in parallel, on Kubernetes, Swarm, and as standalone containers. Enabling or disabling the Kubernetes server does not affect your other workloads.
- Install Docker Desktop
Download Docker Desktop and choose docker version follow your OS
After your downloaded and Installed go to Preferences… and go to Kubernetes menu:
Enable Kubernetes, Deploy Docker, and Show system container then click Apply & Restart after docker and Kubernetes is running so we can run “kubectl version” and “kubectl get ns”
2. Installing helm (install follow your OS)
Go to https://helm.sh/docs/intro/install/
“brew install helm" after successful you can run command for test helm with “helm version” it will be show
and then you go to https://artifacthub.io/ and find “Ingress nginx”
and go to detail for install chart
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
and
helm install my-ingress-nginx ingress-nginx/ingress-nginx --version 3.24.0
After finished install you can run “kubectl get svc -n default” for check ingress-nginx ready or not
If you found problem service can not assign localhost into my-ingress-nginx-controller you can restart docker desktop and check it again, If it still pendding you can restart your laptop
After you ready to create ingress you should modified your hosts file for map Host name to your IP
sudo vi /etc/hosts
Thank you..
