Crane is a small read-only web application that provides enough of the docker registry API to support "docker pull". Crane supports two modes of operation:
- Serve 302 redirects to some other location where files are being served. A base file location URL can be specified per-repository. This is the default mode.
- Local content delivery. In this mode, Crane provides "X-Sendfile" headers to the Apache web server. Apache will deliver the static files including all its optimizations.
Crane loads its data from json files stored on disk. It does not have a database or use any other services. The json files can be generated with pulp by publishing a docker repository.
Crane is a flask app written in Python. It is very easy to deploy and has a small footprint, so it is a great way to provide a read-only "docker pull" API that redirects to a static file service.
Advanced users can configure a search appliance to support "docker search" and can setup repository protection using SSL certificates.
See the current development documentation for more information.
