deploying a node.js K8s cluster with kubectl

• build the image:

make build:

• run the container:

make run

• check whether the server worked:

make curl

• check container's status:

make status

---

useful commands

• exec inside the container:

docker exec -i -t <container name from status> /bin/bash

• check images in disk:

docker images

---

pushing the registry to kubernetes

• in a real production system, we’ll want to build images in one place, then run these images in the Kubernetes cluster
• the system that images for distribution is called a container registry
• using a yaml Kubernetes files (for example, the one inside node_server_example/), you can now deploy the image with:

kubectl create -f  node_example_kube_config.yaml

• after that, you are able to create the service with:

kubectl expose deployment node-app-test

• also, check out the service status with:

kubectl get services

---

cleanning up

• removing the service and the deployment when you are done:

kubectl delete service node-app-test
kubectl delete deployment node-app-test
