Launch a new workspace and execute a command inside your pod

Launch a new workspace in Red Hat OpenShift Dev Spaces and execute a command inside the pod

We will create a Camel file using Red Hat OpenShift Dev Spaces and Karavan, scaffold a Quarkus project using the JBang command-line interface (CLI), package it as container images, and deploy it as a Knative serverless service in Red Hat OpenShift (Figure 1).

The application we will develop is a simple Knative service running a Camel route that logs the HTTP body and replies back the same content to the Curl command (Figure 2).

What you need

• A workspace in Red Hat OpenShift Dev Spaces
• A no-cost Developer Sandbox environment

What you will learn

• How to access the Developer Sandbox
• How to create a workspace in OpenShift Dev Spaces
• How to execute a command

Get started

First, get your no-cost, 30-day OpenShift sandbox environment.

1. Once you successfully log in to the Developer Sandbox, select Red Hat OpenShift Dev Spaces from the menu (Figure 3). 

   

2. The Create Workspace tab will appear. Under Select a Sample, launch an Empty Workspace (Figure 4). 

   

3. From the menu, scroll down to Terminal, then select New Terminal (Figure 5). 

   

4. Run the command lscpu. You are now running the command inside a pod (Figure 6a). 

   

    

   Info alert: The output shows that you are running in the pod, depending on where the pod is and which CPU architecture OpenShift is sitting on, not your laptop.

   For example, if you run lscpu in OpenShift running in ppc64le, you will see something like Figure 6b. 

   

5. Run the command to install the latest JBang CLI (Figure 7).

   curl -Ls https://sh.jbang.dev | bash -s - app setup
   source ~/.bashrc
   jbang version

   

Congratulations! You have successfully launched an empty workspace in OpenShift Dev Spaces and executed a command inside the pod.
