Docker app with Kubernetes (Minikube)
Prerequisites
- minikube
- kubectl
Start minikube:
minikube start
Reuse Minikube's docker daemon (to be able to use locally build docker images):
eval $(minikube docker-env)
Build image
docker build -t docker-k8s-demo:latest .
Run in Kubernetes cluster
kubectl apply -f k8s/deployment.yaml
It will:
- start an application (pod) in Docker container
- scale it to 2 nodes
- create a service to provide single endpoint for pods
- create ingress to route requests to service
Check if it works
curl -Lk $(minikube ip)
You should get back
Hello, world!
