Context
Actually, when generating a new scenario from the CLI, the private attribute is not generated. So you have to know it does exist to play with it.
I discovered this attribute while working on our release workflow.
Feature request
If we don't want to change the actual katacoda-cli behavior, it would be great to add the private attribute as follow to index.json :
"environment": {
"uilayout": "terminal"
},
"backend": {
"imageid": "ubuntu:2004"
},
"private": false
}
