Rancher on Alpine Linux: Deploying Your First Application with Rancher on Alpine Linux

After setting up Rancher, the next step is to deploy your first application. This article guides you through deploying a sample application using Rancher’s user-friendly interface.

Prerequisites:

• Rancher running on Alpine Linux
• Access to the Rancher web console

Steps:

1. Login to Rancher:
   Open your web browser and navigate to the Rancher web console. Enter your admin credentials to log in.
2. Create a New Cluster:
   In the Rancher UI, click on Clusters in the main menu. Then, click the Add Cluster button to create a new Kubernetes cluster. You can choose from various options such as importing an existing cluster, creating a hosted cluster, or creating a custom cluster.
   Follow the on-screen instructions to configure your cluster. For this tutorial, we will create a custom cluster. Provide a name for your cluster and configure the necessary settings.
3. Register Nodes:
   After creating the cluster, you need to register nodes to the cluster. Rancher will provide a command that you need to run on each node to register it. Run the command on your Alpine Linux server to register it as a node in your cluster.
4. Deploy a Sample Application:
   Once your cluster is set up, you can deploy a sample application. In the Rancher UI, navigate to the Catalog section. The catalog contains various pre-configured applications that you can deploy with a single click.
   Search for the WordPress application and click on it. Configure the application settings as needed and click Launch to deploy the application.
5. Monitor the Deployment:
   Use the Rancher UI to monitor the status of your deployment. Navigate to the Workloads section to see the status of your application. Ensure that all components are up and running without any issues.
6. Access the Application:
   Once the application is deployed, you can access it using the URL provided by Rancher. The URL will be displayed in the Rancher UI under the Workloads section. Open the URL in your web browser to see your application running.

Congratulations! You have successfully deployed your first application using Rancher on Alpine Linux. In the next article, we will cover managing and scaling your applications with Rancher.
