cannot deploy docker image form AWS private registry
From an operator perspective, it looks like you're hitting CloudFoundry's password limit of 1000 characters by using the Amazon Elastic Container Registry signed tokens (which are around 2000 chars):

I'm not sure what version of Cloud Foundry your provider is running right now, but support for private docker registries (i.e. registries using HTTPS & basic auth) requires a fairly recent version of Cloud Foundry.
It definitely works in API versions 2.103 and later, as that's what we're running at Meshcloud right now and we have customer successfully using private registries ;-)
