Are you saying you can't create a job from a template?
The main purpose of the template is:
Instead of specifying the plan and server targeting each time you create a job, you can create a job template that will specify these for you. The template can also specify variables that will need to be entered when the job is run.
While this can save you a few steps when running jobs, the biggest benefit of job templates is that, once defined, you can now trigger jobs using a the job trigger API. This will allow you to use nearly any other tool, such as Jenkins or a PowerShell script, to trigger an Otter orchestration job.
However, we plan to expand it to be a lot more useful with better variable selection, etc.
