// substrate-first-node.lock — what a machine must be before a mesh exists.
|
|
//
|
|
// Steps 0 to 5 of the bootstrap (novox/hq 03-DESIGN/01-to-be/07-the-substrate.md): a container
|
|
// runtime, a store, a database per context, that context's schema, and the broker.
|
|
//
|
|
// It stops before step 6, where the control plane runs.
|
|
//
|
|
// The broker generates its OWN certificate, in its own image, into a volume it then mounts read
|
|
// only. Self-signed, because at this moment there is no mesh to issue one and no public name to
|
|
// obtain one for -- and it does not matter, because what a joining node checks is the fingerprint
|
|
// pinned in its token, not a chain or a name (novox/hq ADR 0004). The subject is decoration.
|
|
//
|
|
// PINNED BY DIGEST, and the digest is not decoration: a tag can be made to point at a different
|
|
// image, and this file is applied on a machine with no mesh to ask about anything. These digests
|
|
// belong to the registry the lab raises, which is what a real node pulls from anyway — what is
|
|
// required is a reference that is exact and cannot move (novox/hq ADR 0006).
|
|
//
|
|
// The store's data is a NAMED VOLUME, not a directory on the machine. A directory the host
|
|
// creates is owned by root, and the database runs as somebody else inside the container — so it
|
|
// could not write, and the container crash-looped. A named volume lets the image set up its own
|
|
// ownership, and outlives the container, which is what you want for the thing holding the mesh's
|
|
// state.
