+# insin_anydesk
+
+Insin package that installs [AnyDesk](https://anydesk.com) on Raspberry Pi devices
+(arm64) managed by a self-hosted Insin server.
+
+The package is published to the Insin server and assigned to the `raspberry pi`
+device group in the admin panel. Each device's `insin monitor` picks it up on
+its next heartbeat, extracts the pkg, and runs `postinst` as root.
+
+## Package structure
+
+```
+insin_anydesk/
+├── build.sh              # CI script: pull deb + CLI, pack, publish
+├── src/                  # pkg contents — `cd src && insin pack anydesk@<ver>`
+│   ├── postinst          # apt-installs bundled .deb, enables systemd unit
+│   ├── prem              # stops + apt-removes anydesk on pkg removal
+│   ├── install.cfg       # install_path=/opt/insin/anydesk
+│   └── anydesk_arm64.deb # bundled at build time by build.sh (gitignored)
+└── packages/             # `insin pack` output (gitignored)
+```
+
+Recognised files in the ZIP (per Insin's package manager):
+
+| File          | Role                                                              |
+|---------------|-------------------------------------------------------------------|
+| `postinst`    | Bash script run as root after extraction. New installs and version bumps trigger it; same-version reassignments are skipped. |
+| `prem`        | Bash script run before removal, or before overlaying a new version on top of an existing install. |
+| `install.cfg` | `key=value` overrides. Supported keys: `install_path`, `run_postinst`, `run_prem`. |
+
+Everything else in the ZIP (the `.deb`) is copied verbatim into the install
+directory (`install_path`) alongside the scripts, so `postinst` can reference it
+as `./anydesk_arm64.deb`.
+
+### Metadata
+
+There is no manifest inside the pkg — Insin derives `name` and `version` from
+the `name@version.pkg` filename. The version must parse as `MAJOR.MINOR.PATCH`
+(`Version.Parse`). The pkg version tracks the upstream AnyDesk version:
+`anydesk@6.4.0` bundles the AnyDesk 6.4.0-1 arm64 `.deb`.
+
+Republishing the same version is rejected server-side with 409. To force a
+retry after a failed install, bump the version.
+
+## Environment variables
+
+| Var             | Where     | Purpose                                                                          |
+|-----------------|-----------|----------------------------------------------------------------------------------|
+| `INSIN_URL`     | build     | Base URL of the Insin server (no trailing slash, no `/api`).                     |
+| `INSIN_TOKEN`   | build     | Service token minted in the Insin admin panel (Service Tokens → New token).       |
+| `GIT_URL`       | repo host | Full clone URL of this repo on Gitea (already set globally).                     |
+| `GIT_USER`      | repo host | Gitea username for push/pull (already set globally).                             |
+| `GIT_KEY`       | repo host | Gitea personal access token (already set globally).                              |
+| `ANYDESK_VERSION` | build (optional) | Full deb tag (e.g. `6.4.0-1`). Default: `6.4.0-1`.                           |
+| `PKG_VERSION`   | build (optional) | Insin pkg semver. Default: `ANYDESK_VERSION` with the `-N` suffix stripped.   |
+| `INSIN_CLI_RID` | build (optional) | Override CLI artifact rid. Default: derived from `uname -m`; only `linux-arm64` is currently published, so the runner must be arm64. |
+
+Never echo `INSIN_TOKEN`, `GIT_KEY`, or `GIT_USER` to logs. `build.sh` pipes
+CLI stderr through a sed redactor as a safety net.
+
+## Build & publish
+
+```sh
+./build.sh
+# or override the anydesk version
+ANYDESK_VERSION=6.4.1-1 PKG_VERSION=6.4.1 ./build.sh
+```
+
+`build.sh`:
+
+1. Downloads `anydesk_${ANYDESK_VERSION}_arm64.deb` from
+   `download.anydesk.com/rpi/` into `src/`.
+2. Fetches the latest `insin` CLI (`linux-arm64`) from
+   `$INSIN_URL/api/v1/downloads/cli` into `/tmp/insin/`.
+3. `cd src && insin pack anydesk@${PKG_VERSION}` →
+   `packages/anydesk@${PKG_VERSION}.pkg`.
+4. `insin publish packages/anydesk@${PKG_VERSION}.pkg`.
+
+## Rolling out
+
+Publishing puts the pkg on the server. It does **not** assign it to any
+device. After publish:
+
+- Admin panel → **Groups → raspberry pi → Assignments** → add
+  `anydesk@<version>`, OR
+- `PUT $INSIN_URL/api/v1/admin/groups/<piGroupId>/assignments` with
+  `Authorization: AdminToken $INSIN_TOKEN` and body
+  `{ "packageName": "anydesk", "version": "<version>" }`.
+
+Each Pi picks up the assignment on its next heartbeat (default 10 min) and
+runs `postinst`.
+
+## On-device runtime
+
+- `postinst` and `prem` run under `/bin/bash -c "./<script>"` as a single
+  subshell — one shell invocation, not line-by-line. `set -euxo pipefail` is
+  set at the top so failures surface loudly in the `insin monitor` journal.
+- Exit codes are **logged but ignored** by the agent. A failed `postinst`
+  still marks the package as installed. To force a retry, bump the version.
+- On upgrade, old files are **not** wiped before the new pkg is overlaid —
+  stale files in `install_path` persist unless `prem` cleans them.
+  Irrelevant for AnyDesk itself (the deb owns `/opt`, `/etc`, `/usr`), but
+  worth remembering if the pkg starts carrying additional state.
