2. Docker Hub

What Will You Do¶

You will deploy a publicly available container image from Docker Hub to a number of clusters managed by the Rafay Controller.

We will be using the built-in integration for DockerHub in the Rafay Controller.

Assumptions¶

• You have already provisioned or imported one or more Kubernetes clusters using the Rafay Controller.

• Your clusters have the ability to connect to Docker Hub and pull images.

Step 1: Create Workload¶

• Sign into the Rafay Console.

• Create a workload with Ingress enabled

• In the Ingress tab, provide a unique hostname under the Rafay Domain and create the Ingress

Step 2: Configure Container¶

We will be deploying "tag 0.2" of the "hello" container image from the "nginxdemos" public repository on Docker Hub.

• Create a new Container
• Select "Public Docker Hub" for the Registry
• Select "Public Docker Hub Registry"
• Type in "index.docker.io/nginxdemos/hello:0.2" for the repository and tag
• Save the configuration

Step 3: Publish Workload¶

• Select a cluster/location in Placement
• Publish workload to target cluster

Once the workload is published successfully, access the application's URL. You should see a screen similar to the screenshot below.

Step 4: Access Workload¶

Once the workload is published successfully, access the application's URL. You should see a screen similar to the screenshot below.

** Congratulations! **

You have successfully deployed a publicly available container image from Docker Hub.
