From the survey of every env-file secret (ADR 0086, issue 041): amqp-ping,
minio, mongodb and grafana use the _FILE twin their software honours;
mesh-catalog and model-usage read DATABASE_URL_FILE (a file the mesh
templates, mounted where only the runtime reads it); grafana's secret files
belong to its own account. Two dead deliveries removed: a line nothing read
in amqp-email-forwarder, and mailu's secret.env on four containers that
never read it. The 25 exceptions that remain carry the surveyed reason —
convertible and awaiting a bed, convertible through a generated config file,
the application's own code, or not convertible.
ADR 0086. mesh-controller mounts its six own secrets and names them with
_FILE twins, so no credential of its own reaches its environment. The 35
containers that still read a secret through an env-file carry
secrets-in-environment with the reason; converting each where its software
accepts a path is the per-module work of issue 041.
Piece A + B of ADR 0056, completing the internal-CA work in ff01ada.
Selectable issuer. acme-ca is now a role two providers can satisfy: step-ca
(internal CA) or the new public-acme (a fact-only module, no container/listen)
that serves Let's Encrypt production. A mesh assigns one or the other to satisfy
route-proxy's `requires: acme-ca`.
One directory shape for both. A provider serves the ACME directory's parts the
way the mesh already models any reachable service -- an address (`at`), a `port`
and a `path` -- and route-proxy composes `https://<at>:<port><path>`. step-ca
lets the mesh fill `at` (its node) and `port` (its single listen) and serves only
`path`; public-acme, not being a mesh service, serves all three (overriding `at`
with the public host). Same composition either way.
Empty root means the system trust store. Both providers serve `root`: step-ca
the operator root PEM (settled per mesh), public-acme an empty string. route-proxy
writes it to the CA bundle file unconditionally; the binary now reads an empty
bundle as "the root is already trusted by the OS" and falls back to system roots
(examples/route-proxy/main.go, committed on the mesh-control ADR-0056 branch).
step-ca inits from the operator's root. The operator's root cert, root key and
root-key password are mounted at the smallstep entrypoint's default init paths
(/run/secrets/root_ca.crt, root_ca_key, root_ca_key_password) with the matching
DOCKER_STEPCA_INIT_*_FILE vars, so `step ca init` adopts the operator's root
instead of self-generating one -- the CA that signs is the CA route-proxy trusts.
Route names are labels, not FQDNs. Every routed module now contributes a `label`
(the leftmost subdomain) instead of a full public hostname; the node's public
domain composes the name. Apex (novox.be) is left as a full name -- composeName
has no empty-label/apex convention yet (mesh-control follow-up).
