Applying a YAML manifest

You can deploy a YAML manifest to create a Kubernetes object, such as Node, Deployment, Service, PersistentVolumeClaim, and others. For example, a Kubernetes deployment that requires sensitive data storage, you can apply a YAML manifest to create a Secret object.

Prerequisites

Make sure you have:

• A running Podman machine.
• A running Kubernetes cluster.
• Created a YAML manifest file using the following code, if you do not have one on your machine:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-nginx
spec:
  selector:
    matchLabels:
      run: my-nginx
  replicas: 3
  template:
    metadata:
      labels:
        run: my-nginx
    spec:
      containers:
        - name: my-nginx
          image: nginx
          ports:
            - containerPort: 80

This YAML manifest creates three pods that run the NGINX web server.

Procedure: Applying a YAML manifest to create a Deployment object

1. Go to the Kubernetes component page.
2. Click Deployments in the left navigation pane.
3. Click Apply YAML and select the YAML manifest file. A confirmation notification opens.
4. Click OK.

Verification

1. View the newly created my-nginx deployment on the same page.

2. Go to the Pods component page to view three instances of the NGINX web server running.

   note

   When you apply any other YAML manifest, you can view the newly created object on the corresponding component page.
