- new installs pull incus-base (Zabbly lts-7.0) which ships the same incusd daemon without the QEMU/SPICE/Ceph VM stack (~240 MiB less download, 500 MiB+ less disk) - leave hosts that already carry the full `incus` package untouched - uninstall --purge now also removes the full-incus VM dependencies, guarded by an installed reverse-dependency check (never blanket autoremove) - update the dev docs install snippet to incus-base Generated with Codebuff 🤖 Co-Authored-By: Codebuff <noreply@codebuff.com>

# Development
|
|
|
|
## Building
|
|
|
|
`./build.sh [VERSION]` compiles the Go binary into `bin/vps`. It requires
|
|
any Go that supports toolchain auto-switch (≥ 1.21); `src/go.mod` pins the
|
|
exact toolchain (go1.26.5).
|
|
|
|
```sh
|
|
./build.sh # current OS/arch
|
|
GOOS=linux GOARCH=arm64 ./build.sh # cross-compile
|
|
```
|
|
|
|
**Always `CGO_ENABLED=0`** (build.sh and the release workflow do this). The
|
|
project is pure Go with no cgo; leaving cgo on pulls in Go's `runtime/cgo`
|
|
bootstrap and a C toolchain whenever the standard `net` package is built,
|
|
which fails on machines with a broken/absent gcc. Release binaries are
|
|
therefore static and toolchain-free.
|
|
|
|
## Testing
|
|
|
|
```sh
|
|
cd src
|
|
CGO_ENABLED=0 go vet ./...
|
|
CGO_ENABLED=0 go test ./...
|
|
```
|
|
|
|
The CI release workflow also runs vet+test with `CGO_ENABLED=0` on amd64.
|
|
|
|
### Developing against Incus
|
|
|
|
The panel talks to Incus over its Unix socket (`/var/lib/incus/unix.socket`,
|
|
group `incus-admin`). For a local dev loop:
|
|
|
|
```sh
|
|
# add the Zabbly LTS repo and install Incus (Debian 12/13, Ubuntu 22.04+)
|
|
curl -fsSL https://pkgs.zabbly.com/key.asc -o /etc/apt/keyrings/zabbly.asc
|
|
echo 'deb [signed-by=/etc/apt/keyrings/zabbly.asc] https://pkgs.zabbly.com/incus/lts-7.0/ trixie main' > /etc/apt/sources.list.d/zabbly-incus.list
|
|
apt-get update && apt-get install -y incus-base # container-only build (no VM stack);
|
|
# install the full `incus` package only if you also develop against VMs
|
|
incus admin init --preseed < ... # or use scripts/10-incus.sh
|
|
usermod -aG incus-admin "$USER" # socket access without root
|
|
```
|
|
|
|
`vps install` does all of this on a real host; the exec API is exercised by
|
|
`internal/lx` over websockets (no `incus` CLI needed at runtime).
|
|
|
|
## Releasing
|
|
|
|
Tag a version (`v*`); the `.github/workflows/release.yml` builds amd64/arm64
|
|
with `CGO_ENABLED=0`, runs vet+test, attests build provenance (SLSA) and
|
|
uploads a release with checksums. `install.sh` downloads the prebuilt binary
|
|
from the latest release, falling back to a local build.
|
|
|
|
## Conventions
|
|
|
|
- Small, single-purpose commits — one commit per bug/feature.
|
|
- Commit messages follow the existing style (short subject, then a bullet
|
|
list of what and why).
|
|
- Shell scripts: `set -uo pipefail`, helpers `log`/`die`/`warn`, bash `-n`
|
|
checked, Python one-liners used only where the stdlib is enough.
|
|
- The panel templates embed two languages (`zh` / `en`) via `{{if eq .Lang
|
|
"zh"}}...{{else}}...{{end}}`.
