# Vantage agent (`vantage-agent`)
|
||||
|
||||
The lightweight Go agent installed on every managed server, and the Windows
|
||||
installer that packages it. Extracted from the `vantage` monorepo with its
|
||||
history; the agent is the repository root, so the module is
|
||||
`gitea.hostxtra.co.uk/vantage/vantage-agent`.

## Relationship to the other repositories
|
||||
|
||||
| Repository | Relationship |
|
||||
| ---------------- | ------------------------------------------------------------------------------------------------------ |
|
||||
| `vantage-shared` | a private Go module. `grpc/pb` and `grpc/codec` are the wire contract; `proto/` there documents them |
|
||||
| `vantage` | the control plane. **No import in either direction** — the coupling is the gRPC wire, and it is entirely mediated by `vantage-shared` |
|
||||
|
||||
**`vantage-shared` is private**, so every Go build needs
|
||||
`GOPRIVATE=gitea.hostxtra.co.uk/*` plus a credential. CI writes a netrc from
|
||||
`REGISTRY_USER` + `RELEASE_TOKEN` (**that token needs read access to the
|
||||
`vantage` org**) — twice, because the `msi` job is Windows and Go looks for
|
||||
`_netrc` in the profile directory there, not `.netrc`. Locally, either a netrc
|
||||
or `git config --global url."git@gitea.hostxtra.co.uk:".insteadOf https://gitea.hostxtra.co.uk/`.
|
||||
|
||||
### A wire change is three steps, in order
|
||||
|
||||
`shared/grpc/pb` is hand-written and shared by both sides, so a new message is a
|
||||
compile error rather than a silent disagreement — but only once each side moves:
|
||||
|
||||
1. release `vantage-shared` (and change `proto/vantage/v1/vantage.proto` in the
|
||||
same commit as the Go types)
|
||||
2. bump the pin in `vantage`'s `server/go.mod` — live at the next push to main
|
||||
3. bump the pin here — live only at the next `agent/v*` tag
|
||||
|
||||
The control plane runs ahead of the fleet in between. That was true before the
|
||||
split too; it is now explicit in two `go.mod` files rather than implicit in a
|
||||
shared directory.
|
||||
|
||||
## Releases
|
||||
|
||||
Tags are `agent/v*`, **not** bare `v*`, even though this repository is only the
|
||||
agent. The tag is not a private detail: it is what the fleet downloads by, what
|
||||
`UpdateAgentCmd` carries, and what the control plane greps release tag names for
|
||||
when answering `GET /api/agent/latest-version`. Renaming it would be a second
|
||||
breaking change stacked on the repository move.
|
||||
|
||||
```bash
|
||||
git tag agent/v1.2.0 && git push origin agent/v1.2.0
|
||||
```
|
||||
|
||||
Builds `linux/amd64`, `linux/arm64` and `windows/amd64`, writes `checksums.txt`,
|
||||
creates the Gitea release. A second `msi` job on `windows-2022` builds the exe
|
||||
again, packages it with WiX and appends the MSI to the same release **through
|
||||
the API** — `gitea-release-action` cannot find a tag with a slash in it.
|
||||
|
||||
### The self-update path, and what the move broke
|
||||
|
||||
`internal/sync` downloads its own replacement from
|
||||
`<gitea>/vantage/vantage-agent/releases/download/<tag>/…`, verifying the
|
||||
SHA-256 from `checksums.txt` before swapping itself. That path is **compiled
|
||||
into the binary**.
|
||||
|
||||
**Every agent built before this move has the old path — `mrhid6/vantage` —
|
||||
baked in, and releases are no longer published there.** For those agents the
|
||||
push-button update in the UI will fail: the download 404s. They are not
|
||||
stranded, because `/update` and `/update.ps1` are generated by the control plane
|
||||
at request time and point wherever the current server says, so re-running the
|
||||
update one-liner on a host moves it onto a build that knows the new address.
|
||||
After that, self-update works again permanently.
|
||||
|
||||
This was a deliberate choice — the alternative was publishing releases to a
|
||||
repository that no longer holds the source — but it means **the fleet needs one
|
||||
pass of the update one-liner**, and the control plane must be redeployed with
|
||||
the new release paths *first*, or the one-liner points at the old repository
|
||||
too.
|
||||
|
||||
## What the agent will not do
|
||||
|
||||
- **It never reboots a host.** `ApplyUpdatesCmd` installs and stops there;
|
||||
`inventory.reboot_required` reports that one is owed.
|
||||
- **It decides what it will not touch.** The protected workload set is computed
|
||||
and enforced agent-side — `vantage-agent.service`, `VantageAgent` on Windows,
|
||||
and its own container ID from `/proc/self/cgroup`. The control plane may name
|
||||
a target; the agent decides what it will do to itself. A server-side denylist
|
||||
alone would be bypassed by the next dispatch path someone adds, and the
|
||||
failure is unrecoverable from the UI.
|
||||
- **The console relay dials `127.0.0.1` only.** The host is hardcoded here, so
|
||||
the control plane can name a port and nothing else.
|
||||
- **No `authorized_keys` management on Windows**, and no package inventory: a
|
||||
Windows agent never calls `ReportPackages`, so no `server_packages` document
|
||||
exists for it at all — a different, earlier state than the `unsupported` a
|
||||
Linux distribution reaches when its family has no security feed.
|
||||
|
||||
## Platform split
|
||||
|
||||
Windows support is build tags, not runtime branches — `systemd_linux.go` /
|
||||
`services_windows.go` and the matching `control_` and `logs_` pairs. Windows
|
||||
collection runs PowerShell through `internal/winexec`, and **every script that
|
||||
reports data emits JSON that a build-tag-free parser reads**, so those parsers
|
||||
are tested on Linux. This module has no Windows CI: the control verbs and
|
||||
`serviceDisplayName` emit no JSON, have no parser, and are exercised only by
|
||||
running the agent on Windows.
|
||||
|
||||
Windows updates go through the Windows Update COM API
|
||||
(`Microsoft.Update.Session`) rather than the PSWindowsUpdate module, which would
|
||||
need a PowerShell Gallery install on every host and fails on an air-gapped
|
||||
fleet. `CurrentVersion` is empty on Windows and `NewVersion` carries the KB
|
||||
article ID: a Windows update is not a version bump of a named package.
|
||||
|
||||
## Two constants that mirror the control plane
|
||||
|
||||
Neither can be shared — this is a separate module and the control plane's are
|
||||
under `internal/` — so both must change in step, by hand:
|
||||
|
||||
- the workload log cap, **500 lines and 256KB whichever binds first**, mirrored
|
||||
in the control plane's `services.MaxWorkloadLogLines`
|
||||
- `streamHealthyAfter` and the 70s command-stream watchdog, which pair with the
|
||||
control plane's 20s `PingCmd`. The watchdog arms only **after** a first ping
|
||||
has been seen, so an older server that sends none is treated as working rather
|
||||
than put into a reconnect loop.
