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.
