Deploying Kubernetes Clusters With Docker Desktop
The following are the steps to deploy a Kubernetes cluster with a Docker Desktop:
Step 1: Verifying Docker Desktop Installation
- To ensure Docker Desktop is installed correctly, open a terminal or command prompt and run.
- This command should display information about the installed Docker version.
docker version
Step 2: Enabling Kubernetes In Docker Desktop
- Open the Docker Dashboard.
- Select “Settings” from the left sidebar.
- Navigate to the “Kubernetes” tab.
- Check the “Enable Kubernetes” checkbox.
- Click “Apply & Restart” to save settings and then select “Install” to instantiate the required images for the Kubernetes server.
Step 3: Verifying Kubernetes Installation
- Check the Kubernetes installation by running the `kuberbetes version`.
- This command should display the Kubernetes client and server version, indicating a successful installation.
kubectl version
Step 4: Deploying A Sample Application
- Create a YAML file, `sample-deployment.yaml`, with the following contents:
apiVersion: apps/v1
kind: Deployment
metadata:
name: sample-app
spec:
replicas: 3
selector:
matchLabels:
app: sample-app
template:
metadata:
labels:
app: sample-app
spec:
containers:
- name: sample-container
image: nginx:latest
ports:
- containerPort: 80
- Apply the deployment to the Kubernetes cluster:
kubectl apply -f sample-deployment.yaml
Step 5: Checking Deployment Status
Monitor the kubernetes deployment status with:
kubectl get pods
Step 6: Accessing The Deployed Application
- Retrieve the external IP address of the deployed application:
kubectl get svc
Access the application in a web browser using the provided external IP address.
