Hi SteadyFox10 , unfortunately trains-agent currently supports only docker as a container solution (I guess they became the de-facto standard)
That said, there is the option of virtual environment, where the trains-agent installs everything inside a newly created virtual environment. That actually makes it quite easy to expand to other use cases. Essentially the docker option will spin a docker install trains-agent inside the docker and run it execute command.
Do you fee like playing around with it, I think you could quickly integrate it with https://slack-redir.net/link?url=https%3A%2F%2Fsylabs.io%2Fdocs%2F . I'll be happy to help :)
