How to Cache Nodejs Packs in inventory.toml ?

[mautops]

because of the network, we can not visit aws s3 directly，so i cached the Nodejs Packs in inventory.toml into local registry, is there a way to modify the default download url ?

Sorry, we don't have a way to modify the download urls at present, other than forking the buildpack and modifying inventory.toml.

What kind of restrictions do you have? It sounds like you might have to fetch from S3 via a proxy? If we offered proxy support, would that work? Or do you want a way to provide your own inventory.toml?
