Skpr is a container-based hosting platform. The skpr snap is the CLI client used for deployments, configuration etc. that talks to the remote service.
The skpr client needs to read a number of different configuration files from a .skpr/ directory in each project root that uses the tool.
These files differ from project to project.
Therefore it cannot use strict confinement.
NB I have also made another request to move this tool to an organisation account named ‘skpr’. See Please transfer skpr snap to skpr org
