deploying a node.js K8s cluster with kubectl

1. Build the image:

make build:

2. Run the container:

make run

3. Check whether the server worked

make curl

4. 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
