Deployments, finally we have reached to the last major object in Kubernetes. Deployments take everything we have being doing so far and encapusaltes it. What I mean is the following:

Of course you can have more than 1 pod in replica set. Yes, it is replica set when under Deployment, not replication controller. But the purpose is the same.

So let's create our Deployment now:

To create a deployment again we have two ways:

• Iterative - With kubectl create and so on
• Declarative - Using YML / JSON file, I will be using this one.

As I am bored with the iterative way, let's clean our env and create a deployment. I won't delete my service as I will use it later.

First, let's create our YML file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello-deploy
spec:
  replicas: 10
  selector:
    matchLabels:
      app: hello-date
  template:
    metadata:
      labels:
        app: hello-date
    spec:
      containers:
      - name: hello-pod
        image: andonovj/httpserverdemo:latest
        ports:
        - containerPort: 1234
