cork-server

The always-on Linux heart of the lab: the cork server, running Docker and Portainer, holding every keeper service in the air. Containers come and go; the server does not.

Its duties are the quiet ones — the services the household forgets it has until they stop: the greeter at the login, the memory the agents drink from, the small daemons that keep the moss wet and the lights on. Portainer is the wheelhouse; the containers are the rowers.

It is the stone the rest of the garden leans on, which is why it gets the Keeper’s mark: self-hosted, always lit, and never once been the interesting thing on fire.

At Kildare, the stories are careful to say, Brigid kept a fire — the fire, the one that burned for centuries without going out, tended by the nuns in shifts, nineteen at a time in the old account, because a flame that outlives its keepers needs keepers who outlive their shifts. The doctrine under it is the oldest one the country has: some lights must not go out, and the keeping of them is not glory — it is a rota. The garden’s version is named for cork, the bark that is stripped without killing the tree and that floats no matter how long it is in the water. The cork server is Kildare’s fire in a metal case: a Linux heart that does not sleep, Docker carrying the service containers the way a bellows carries air to where it is needed, Portainer the little window the nun looks through to check that everything is still lit. Nobody thanks a flame for burning; that is the flame’s whole trick — be so reliable that gratitude forgets you, and so warm that the house remembers anyway. The moss grows thickest here, on the stone that is never moved and always warm, which is precisely where moss likes to be.
