## TL,DR
A caching proxy for Docker; allows centralised management of (multiple) registries and their authentication; caches images from *any* registry.
Caches the potentially huge blob/layer requests (for bandwidth/time savings), and optionally caches manifest requests ("pulls") to avoid rate-limiting.
### NEW: avoiding DockerHub Pull Rate Limits with Caching
@ -78,6 +79,7 @@ for this to work it requires inserting a root CA certificate into system trusted
- Map volume `/docker_mirror_cache` for up to `CACHE_MAX_SIZE` (32gb by default) of cached images across all cached registries
- Map volume `/ca`, the proxy will store the CA certificate here across restarts. **Important** this is security sensitive.
- Env `CACHE_MAX_SIZE` (default `32g`): set the max size to be used for caching local Docker image layers. Use [Nginx sizes](http://nginx.org/en/docs/syntax.html).
- Env `ENABLE_MANIFEST_CACHE`, see the section on pull rate limiting.
- Env `REGISTRIES`: space separated list of registries to cache; no need to include DockerHub, its already done internally.
- Env `AUTH_REGISTRIES`: space separated list of `hostname:username:password` authentication info.
- `hostname`s listed here should be listed in the REGISTRIES environment as well, so they can be intercepted.
