Hi. Thanks for the response. I can follow-up why potentially you would do that but I can also very much see solutions for that e.g. checking the disk hashes if something cot corrupted in the meantime or like at least “readonly disk” which would already help the web-user to be able to use everything. This could e.g. inject a variable/lockfile whilst deploying the other instance but well you are the experts on this
Besides that coming back to your question:
Well as given the Dockerfile does COPY . . and therefore allow to copy the custom theme into ghost. Sure thing one could upload the theme in ghost admin and therefore avoid a redeploy but that is not programmer friendly at all - especially in case the programmer would just be the service provider and not even have access to the CMS after all.
Also I am modifying Ghosts core code to fit my needs.
So tldr: I think recommending “dont redeploy” is not a good option since render should be my “deploy-whenever-you-want” provider
