route-proxy's own Dockerfile documents the shape it has always needed and
never had: 'the proxy source is not vendored here... the build context is
the mesh-controller repository root, and this Dockerfile compiles
./examples/route-proxy from it.' Nothing in the mesh could do that — the
build command clones one repository and builds every artifact from
within it, so route-proxy has never once been built through the pipeline,
consistent with it never having been assigned anywhere. Found attempting
exactly that build tonight: 'stat go.mod: file does not exist', because
the context was mesh-catalog, which does not have one.
An image artifact may now carry a context: {repository, ref}, cloned
fresh alongside the module's own tree. The recipe (Dockerfile) is still
read from the module's own directory, at the module's own commit — only
docker build's own context argument moves. Packaging and source stay
exactly as separate as route-proxy's own comment already said they were,
now for real.
TestTheForgesSshPortIsGivenByTheNumberTheForgeCallsIt exercised a settings
override from '2222' to 222 — but 2222 was never a real port anywhere,
just a mistake in gitea's own manifest (fixed alongside this: listens.port
is now 22, the container's real internal sshd port, matching every other
module's convention, and ports declares 222:22 directly — 222 has always
been the real, fixed public git-ssh port, needing no per-node override).
Split into two tests: the fixed default with no override, and a genuine
override case for a hypothetical node whose predecessor used a different
number, keyed correctly by 22.
TestTheResolverAndWhatAsksItComposeOnOneMachine set Rendering.Names but
FactNodeZones reads Rendering.Machines (novox/hq issue 111 split the two
apart: every name the mesh serves vs. the machines subset) — a loose end
from that merge, not exercised until now. Both are the same map in this
test's scenario, so both fields are set.
Every cutover done on novox tonight (drive, files, files-api, git,
keycloak, umami) dropped the <label>.<node>.internal alias HAL always
paired with the public hostname — found only when the operator tested it
by hand. Not a security boundary (a predecessor proxy served both as a
convenience, reaching a service over the VPN without a public TLS round
trip, not as access control), so restoring it is composing the same
convenience the same way the public name already is: <label> joined to
the node's own private address (r.At), independently of whether a public
domain exists to join the other half to.
composeName's signature changes (publicDomain, internalDomain) but its
shape does not — additive, label-gated, apex-aware, exactly mirroring the
public half it already did. A contribution the mesh writes both names
into is the entire fix; route-adapter and route-proxy pick up internal-
name whenever they're updated to serve it, not before, so this alone
changes nothing about what is live on any node yet.
ContributionsFrom settled to whichever of a module's several contributions to
one requirement sorted first, arbitrarily — the grant minted for it then
carried that contribution's label and port under a credential the OTHER
contribution's consumer never sees, and collided with that same
contribution's own entry from contributions() besides.
Confirmed live: minio's two route contributions (files-api, files) produced
three entries in route-adapter's received file — files-api twice, once
credentialed and once not, files not credentialed at all. Every
single-contribution module (gitea, keycloak, umami) already mints an unused
credential for `route` too — route never needs one, by its own
documentation — but with exactly one contribution to match there was nothing
to collide with, so it never surfaced.
Where a module contributes more than once, there is no single value to
settle on. The module still asks, still gets its one credential — a pair
credential is not a place for a label or a port anyway — and each named
contribution reaches the provider on its own, unchanged.
No cleanup needed for the secret already minted live for minio+route: the
sealed blob is a random pair credential unrelated to Values, which is
recomputed fresh on every plan/push regardless.
A module's contributes was map[string]map[string]any — one JSON object key
per requirement, structurally exactly one contribution to "route" ever.
minio needs two public hostnames (the S3 API and the console), which is
two different contributions to route from one module, and nothing let it
say so.
This is the same shape of problem ADR 0094 solved for secrets (a module
needing several values from one provider that gives one per pair):
contributes now accepts either the ordinary {label, port} object, or an
object of local names to several such objects. Detected per requirement
key by what's inside, since (unlike secrets' string-vs-object split) both
shapes are JSON objects: an ordinary contribution's fields are scalars, the
several-instance shape is local-name -> object. Confirmed against every
module.json in mesh-catalog before relying on that split.
Both route-proxy and the migration-era route-adapter already key generated
routers off the composed hostname (Values["name"]), not the module name,
so two contributions with the same From reach them as two independent
routes with no changes needed on the receiving side.
The map the control plane hands a resolution holds both: the machines, and every name
the mesh was told to route to whichever machine serves it. A container's hosts wants all
of it, so a routed name resolves to the proxy. A resolver's zones want only the machines:
told the mesh's suffix is its own it answers authoritatively for everything under it and
forwards none of it, so a routed name with the suffix appended — drive.example.test.internal
— is a name nobody will ever ask for, standing beside the machines and looking as real.
Found composing the resolver's first assignment on a live machine, before pushing it.
hq issue 111.
hal dnsmasq-app conversion, hq 08-connectivity. Converting the resolver from the module it
replaces made it forward what it cannot answer, which is what the predecessor's does, and
that found two things the controller did not say.
A resolver that forwards must not send a mesh name it does not know upstream: the
`node-zones` fact now carries `local=/<suffix>/` beside the wildcards, written here rather
than in the daemon's configuration because the suffix is the mesh's choice and this file is
the one place the mesh writes what it chose. The default lives in one helper now instead of
being spelled in two functions.
The predecessor points the container runtime's `dns` at the machine's own tunnel address —
a container cannot reach the machine's loopback. A module writing that key needs the
address, and `${machine:at}` is the machine's name; a runtime's resolver list cannot be a
name it would need that resolver to look up. So a module may say `${machine:address}`: what
`at` resolves to, read from the same names the hosts file and the wildcards are written
from, absent — and refused — off the network like `at` is.
The `mesh-resolver` and `resolver-data` constants go: nothing provided or consumed either,
the fact and `mesh-addressing` are the mechanism, and a requirement nothing provides is
refused at resolution.
Tests: the catalogue's dnsmasq, resolv-conf and resolved-split-dns manifests are parsed
and composed as a machine would receive them — fixed upstreams, no-resolv, 127.0.0.1, the
machines file, the runtime's key, the pair that decides what a machine asks refused on one
node; and on a real mesh the resolver's machines file is composed with a wildcard per
machine on the network and composed again without one that left, mirroring the hosts fact.
Beside each sealed connection genesis wrote, the port this machine put the
seat's holder at: `${seat:mesh-store:5432}` for the three stores,
`${seat:mesh-broker:…}` for the bus, the plain AMQP port and the management API.
Filled from the node's settings when the control plane composes its own
declaration; empty — the sealed value stands — when the mesh has nothing to add.
On its own, after the commit before it is built and running: a control plane
that does not know the placeholder passes it through as the value, and this
manifest is composed by whatever control plane is running when it is pushed.
The reader ignores an unfilled placeholder either way, and a test holds it to
ignoring exactly what this manifest says.
novox/hq 04-ISSUES/102
Three readers did not follow a moved foundation port (novox/hq 04-ISSUES/102),
and each took the control-node down in its own way: the control plane's own
store and broker connections, sealed at genesis with the port inside; and every
build the mesh ever recorded, kept as `<registry>:<port>/<module>/<artifact>@…`.
The control plane cannot open its own sealed connections to move a port, and it
cannot bind the store as a consumer would — a binding mints a credential. So its
settings get a third twin, `NAME_PORT`, read on top of the sealed value by the
store, the broker, the management API and the bus connection, and filled into
its container by a placeholder that names a seat, `${seat:mesh-store:5432}`,
from the node's given or mesh-assigned ports — never the manifest's number, and
empty when the mesh has nothing to add, so what genesis wrote stands. A value
that is still a placeholder is nothing said, aloud: the manifest naming it lands
in the next commit, once every control plane that composes it knows it.
A build is now recorded by digest and path — `artifact-store://<module>/<artifact>@…`
— and the store's address is composed in where a reference is used: the
declaration, the trust file, the bases a build is handed, a replay to the
catalogue. Over the network as `<node>.internal:<port>`; on the store's own node
before any network exists — every genesis push before its "network" step — by
loopback. A reference recorded before this, with an address, is re-routed the
same way when the mesh built it. The trust file and every provider's address
come from one derivation: the node's given port, over the mesh's assignment,
over the manifest's number.
novox/hq 04-ISSUES/102
Review of the registry work found the seat node-scoped: a second `distribution` on another
machine resolved cleanly there, and only afterwards did the mesh notice `artifact-store`
offered by two nodes, with every consumer elsewhere refusing to choose. A node-scoped
requirement with one candidate installs that candidate, so anything that wanted the store
beside it would have raised a fresh, empty store on the wrong machine first.
The claim is mesh-scoped in mesh-catalog now; this holds the catalogue's manifest to it —
a second store anywhere is refused by name, where it is assigned.
Review found the first pass aliased its answer under both ends of a mapping, which is
wrong wherever two mappings share a number: the alias lands on a key belonging to another
mapping, the later write wins, and the filter and the container then disagree — the very
fault this change exists to close. Two reproduced cases: a module publishing 8080:80 beside
9090:8080 had an explicit setting silently overwritten; a module publishing 4001:80 beside
4002:80 composed both containers onto one machine port, where before it was safely refused.
Now a mapping's answer is filed once, under the end the module names in its listens — the
number the plan, the filter, the openings, the guard and the consumer all ask for — and a
key that names two mappings is refused in the same words as a setting that does.
Also: the guard assertion in the end-to-end test failed open when the resource was absent;
the plan-mirroring helper now says it stands in only where the plan does not allocate, and
the assertions it feeds are narrowed to the port under test.
A module publishing `2222:22` — the machine's own ssh daemon holds 22, so
the module takes 2222 and says so in `listens` — could not be moved. The
setting was read against the last segment of each mapping alone, so the
number the module uses everywhere else was refused as a port it does not
publish, and the node's every push failed for as long as the setting was
stored. The one key that was accepted, the container's own port, was then
read only when the container's mapping was rewritten: the mapping moved
and the ports map, the filter, the adopted node's openings, its guard and
what a consumer is told all stayed on the number the software had left.
Either end of a mapping now names it, and a given port comes back under
both, so every reader finds the same number under the key it holds.
Ambiguity is refused where it is real — one number naming two different
mappings, or the two ends of one mapping given two different numbers.
${port:…} answered only inside a file's content, and the one place a module
routinely writes its own address is a container's `env` — where the literal is
wrong on every node whose assignment differs from the manifest's number, and
wrong again on a node given that port as a setting (ADR 0100). Nothing checked
it: the value is a string like any other, and it fails at runtime, on one node.
Filled by the control plane, like a bound value: a port is not secret, so there
is nothing for the host to be the only witness of and it learns no new field.
That is the line ADR 0086 draws — its objection is to a secret being in an
environment at all, not to who fills one in — so a port crosses it and a
credential still does not. Same guard as before: a port the module never said it
listens on is refused, now naming the container and the variable.
The env map is the catalogue's, shared by every node running the module, and the
resource around it is a shallow copy, so a filled value goes into a fresh map —
otherwise the first node composed writes its own port into the manifest and
every node after it is told that one.
Inert on the catalogue as it stands: ${port:…} is written in one other place in
it, a file. Renamed off _files, which this no longer is.
The builder carries a binding because at genesis nothing provides
`package-registry` to resolve one from; once the forge is a module the same
consumer is told what the forge serves. Nothing held the two to the same number,
so the catalogue could drift into dialling one port before the forge is assigned
and another after.
And `at` is now protected, for the reason it had to be: a setting that moves it
points the builder, and the registry password it sends, at a host somebody else
chose.
novox/hq 04-ISSUES/085
The package registry was the one foundation port not resolved from what its
module serves. Nothing in the controller had to change for it — `ports` on the
forge moves its container, what it serves and what consumers are told, and the
builder's carried binding is settable like any other mergeable file — but
nothing said so, which is how it came to be special in the first place.
Two tests over the catalogue's own manifests: the forge's port is given on a
node and reaches what it serves, and the builder's carried binding takes the
port from the node while keeping who the binding is with.
novox/hq 04-ISSUES/085
A secrets object with one local name delivered no file. Two requirements could share
a local name. secret recover and the export could not tell two locals apart. The
recipe check missed continued lines and read heredoc bodies as bases. repo:tag@digest
kept the tag in the repository. ask now publishes mandatory, so a tool nothing serves
is said at once rather than after the wait.
build.on takes {arg, image@sha256:…} beside {arg, module, artifact}: the image is
copied into the mesh's registry before the build (ADR 0096) and the recipe reads the
copy from the argument. A FROM or COPY --from naming a registry image the manifest
did not declare is refused before the build, naming it and the remedy; stages,
declared arguments and scratch are not fetches (novox/hq 04-ISSUES/064, ADR 0097).
The lab's vault refused a declaration naming two files with one identity: the
two secrets of one consumer. The holder's suffix is in the resource id and the path now.
Two consumers of one same-node provision produced two raw needs and, fanned out per
consumer, four — the same credential twice for each. Harmless, since a pair is one
row however often it is asked for, and wrong all the same.
The lab's two-secrets consumer was given one credential and no file: the expansion
ran on the resolver's walk over names, on whichever module mentioned the provision
first, and the per-consumer pass copied that. It expands in that pass now, and a
test has two consumers of one provision, one keeping one file and one keeping two.
secrets: maps a requirement to several files under local names. Each local name is
its own need, its own pair credential (the pair is keyed on it: migration 0027),
its own file on the consumer, its own holder at the provider (the identity with the
local name after it) and rotates apart from the others. The plain shape is
unchanged and every existing row is the credential it was (novox/hq 04-ISSUES/069,
ADR 0094).
The host's error text may carry a duration or a counter, and a resource looping on
it would never have read as stuck. The previous row is read and compared here.
Stuck needs a start to say. A container may mount the file a binding lands in; the
runtime socket is declared under both of its spellings; the catalogue-wide test
takes MESH_CATALOG.
Brought back from 53eb000, withdrawn because it refused the builder's mount of the
container runtime's socket. A path is declared as the module's own (a directory or
file resource, or where a secret, grant or contribution lands), as the operator's
(an accesses entry, ADR 0051), or as the machine's (a facility a declared capability
grants: container-runtime grants its socket). Every catalogue manifest passes, and
a test says so (novox/hq 04-ISSUES/026, ADR 0091).
The control plane runs as 65534 and crash-looped on permission denied the
first time its credentials were mounted as files the host wrote as root at
0600 — the env-file shape hid this because the daemon reads an env-file on
the host side. The composer now gives a module's secret files the owner the
manifest names.
The broker settings take a _FILE twin like the store connections; the
catalogue engine refuses a secret placeholder in a container's env and a
secret-carrying env-file unless the container says why with
secrets-in-environment, which stays in the catalogue and never reaches the
machine.
From review: the export counted any operator-sealed row as recoverable, so a
secret sealed to a replaced key was reported as openable with the current one;
replacing the key counted orphans in one table of two; and a pair credential
held from two providers was recovered as whichever row came first. The export
now lists what the current key opens, what an earlier key opens, and what has
no copy; `secret recover` takes --provider and refuses ambiguity; files that
must not exist are created exclusively; one constructor builds the export for
the operator's file and the vault's disk alike.
The secret the vault provides a module is the credential of the consumer↔vault
pair, and so is every credential a provider grants; sealing only own secrets
to the operator left exactly those unrecoverable. Same column, same call; the
export and `secret recover` address a pair by consumer node, module and the
provision's name, and say which kind each entry is.
