Prod does not really have much in it. Ideally I'd just like to use the command line to tell prefect server to load up the flow in the existing docker container without the flow present outside of it.

You can do this with the new

prefect build

and

prefect register

CLIs. Build will build your flow(s) (building any images, pushing source to S3, etc...) and write the output to a JSON file. This file can later be used with

prefect register

with the

--json

flag to register the flows in a project (or multiple projects) without requiring access to the flow source itself.

I wish I saw this. Interestingly I am using docker storage and the normal build process. I now am running my container in once off to 'self-register' I worked out how to load the cloud pickled flow and register it again with the container I have made. That works perfectly outside the container but I want to have the container do it itself. Now I am trying to use the client api and to do a register of that cloud pickled flow

in my flow to get the code that is used to build the lists of files and requirements in my custom docker storage as the prefect.context wrapped python 'exec' does not have globals passed.

Ah, nice catch, can fix.

Thanks for adding the local directory. I switched over to the cli way. Now you fixed adding the local directory I have nothing outstanding. All working working (pre your fix). I'll go back and take those lines out. Next thing for me is to make a prefect task to register the flow. I can use an exec to run the command but I think I'll try and use the library.
