Kubernetes - Use Local Docker Images in Kubernetes (notes)

Build your dockerfile to create a docker image:

docker build -f YourDockerfile -t samplewebapp1 . --no-cache

Configure the deployment.yaml file to load image locally

      containers:

      - name: sample-application

        image: samplewebapp1:dev

        # never pull the image policy

        imagePullPolicy: Never

        ports:

        - name: http

          containerPort: 80

          protocol: TCP

docker context use default

minikube start

minikube image load samplewebapp1 

minikube image ls

minikube image rm samplewebapp1 

kubectl apply -f .\manifests\configmap.yml

kubectl apply -f .\manifests\deployment.yml

kubectl apply -f .\manifests\service.yml

kubectl get configmap sample-configmap --output json

# returns a URL to connect to a service
