deployImage is what you want now. The config json goes into definition, services is deprecated in favor of services in the config.
I’ve also wanted a single mutation, like deploy, that takes image, config, secrets, counts, size, etc and applies everything in a single deployment. Volumes should use the existing volume mutations since they are individually addressable objects off the app rather than a point-in-time configuration linked to a deployment. Same for certificates and IP addresses.
I can hack this together for you, but it’ll probably be next week.
