Description

Starting in Docker v23.0, the build command has been updated. It still works, but raises a DEPRECATION WARNING as shown below.

...
Processing 'context' component...
  Building Docker image...
DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
            Install the buildx component to build images with BuildKit:
            https://docs.docker.com/go/buildx/
...

By now, it still works, but needs to be resolved to prevent issues while deploying TeraFlowSDN.

Deployment environment

• Operating System (include version): any
• MicroK8s (include version and add-ons): any
