​The Pollen operator is a machine charm designed to deploy and manage Pollen directly on VMs and bare metal. [Pollen](https://github.com/dustinkirkland/pollen) is a high-performance, scalable, free web server that provides "Entropy-as-a-Service" by offering small strings of entropy over both HTTPS and clear-text HTTP connections.

This charm does not use an OCI image, as it runs directly on a machine rather than in a container. The charm uses the [pollen](https://github.com/canonical/pollen/blob/main/snap/snapcraft.yaml) [snap](https://ubuntu.com/core/docs/snaps-in-ubuntu-core) to install Pollen during deployment.

Canonical provides a Pollen server as a service to the Ubuntu community at `https://entropy.ubuntu.com`.
