Differences from Render

Six keys or features do not have the same result on Ferry as on Render.

What Ferry does with a key of render.yaml

The differences

Key or feature	On Ferry
`plan`	It becomes resource limits: the memory of the plan and, for services, its CPU. `free` gets 0.5 CPU, not the 0.1 of Render.
`region`, `scaling`, `previews`, `ipAllowList` and other options of the host	Ferry has no such option. It ignores them.
`repo`	It has no default. Render uses the repository of the blueprint itself. Ferry does not know it.
`image.creds`	Ferry ignores it. Ferry does not support private registries.
Secret files	Ferry does not support them. Use environment variables.
`port`	A Ferry key. Render has no such key.

Set repo on each service. Or deploy local code:

Terminal

ferry up NAME

The Render migration guide shows a full migration.

A render.yaml on Ferry

Most render.yaml files apply with no change. Ferry gives a warning for what it does not use.

Env var references

A reference points a variable at a datastore or a service. Ferry puts the real value there at start.
