Skupper command overview

Resource configuration and status commands

• Create, update, delete, and status.

• Site, Link, Listener, and Connector.

• Generally, they submit the resource to the controller and wait for ready state (Listener and Connector wait for configured state).

• Create operations take a name option, which is the name of the resource created (.metadata.name).

• Update operations shift the resource status from ready to pending while the change is taking place. It waits for ready status.

• The status command gets the status info from the resource status fields.

Resource output generation commands

• These commands generate structured output, YAML or JSON.

• They generate output that represents Skupper resources.

• You might want to direct the output to a file, cut and paste it, or pipe it to kubectl.

• These are good for learning about the resources.

• Link generate is a little different from the other generate commands. In general, the generate commands are helping you produce resources for your current site. By contrast, link generates a link resource (and a secret to go with it) for use in a remote site, to the current site.

• The token commands are for creating links!
