Containerized Polipo web cache

Polipo Image for Docker

This image is built on Alpine Linux with IPv6 support (using Musl libc). Polipo has been abandoned after release 1.1.1, but it's still great software. This unofficial release 1.1.2 includes patches from upstream and DG's tweaks to support build on newer systems.

Ports

Polipo is configured to listen on port 3128.

User

Polipo runs as user nobody, uid 65534.

Volume

/var/cache/polipo

Path to the disk cache directory. Polipo will store files up to a certain size in its disk cache.
