Creating dev containers with `odo` and Devfile on a local Kubernetes cluster

Devfile is standard for declaring containerized development environments. We may use Devfiles in combination with odo to set up and tear down dev environments on Kubernetes.

To create a dev environment on a local Kubernetes cluster with Devfile and odo, only three steps are necessary:

1. Start the local Kubernetes cluster E.g. the integrated Kubernetes cluster of Rancher Desktop.
2. Install the odo CLI E.g. on macOS with Brew, run

   brew update && brew install odo-dev
   

3. Create a Devfile

   mkdir -p /tmp/devfile
   cd /tmp/devfile
   cat <<EOF > .devfile.yaml
   schemaVersion: 2.1.0
   components:
   - name: thedevcontainer
     container:
       image: ubuntu:22.04
       command: ['sleep', 'infinity']
       mountSources: true
   EOF
   odo dev
   

The above should start a pod running Ubuntu 22.04 in the local Kubernetes cluster and we may exec into it and run commands.
