13.2. Proxy cache limitations
Proxy caching with Red Hat Quay has the following limitations:
- Your proxy cache must have a size limit of greater than, or equal to, the image you want to cache. For example, if your proxy cache organization has a maximum size of 500 MB, and the image a user wants to pull is 700 MB, the image will be cached and will overflow beyond the configured limit.
- Cached images must have the same properties that images on a Quay repository must have.
- Anonymous users cannot pull images through a proxy cache if the image has not been previously cached. This operation requires the creation of a new repository within the proxy organization to store the cached image, and anonymous users do not have the necessary permissions to create repositories.
