# First run on Debian

Everything below assumes the working root is `/opt/opn-rustproxy`.

## 1. Checkout

```sh
sudo mkdir -p /opt/opn-rustproxy
sudo chown -R "$USER:$USER" /opt/opn-rustproxy
cd /opt/opn-rustproxy
git clone https://git.linuxiarz.pl/gru/rustproxy-opnsense-repo packaging
cd packaging
```

RustProxy is intentionally not cloned manually. The scheduler fetches it to `/opt/opn-rustproxy/source/RustProxy`.

## 2. Install Debian dependencies

```sh
sudo bash builder/debian/install.sh
```

This installs Docker, cron, Git, zstd and the scheduler, then starts `docker` and `cron`.

## 3. Configure

```sh
sudo editor /etc/rustproxy-opnsense-builder.env
```

For the basic local build, use:

```text
PACKAGING_REPO_URL=https://git.linuxiarz.pl/gru/rustproxy-opnsense-repo
PACKAGING_REPO_REF=HEAD
PACKAGING_WORKDIR=/opt/opn-rustproxy/packaging

APP_REPO_URL=https://git.linuxiarz.pl/gru/RustProxy
APP_REPO_REF=HEAD
APP_WORKDIR=/opt/opn-rustproxy/source/RustProxy

STATE_DIR=/var/lib/rustproxy-opnsense-builder
DOCKER_CACHE_DIR=/opt/opn-rustproxy/cache

BUILD_MODE=docker-freebsd
FREEBSD_RELEASE=15.1-RELEASE
FREEBSD_ABI=FreeBSD:15:amd64
FREEBSD_ARCH=freebsd:15:x86:64
OPNSENSE_ABI=26.7
DOCKER_IMAGE=rustproxy-freebsd15-builder:15.1-rust1.88
RUN_LINUX_TESTS=1

PUBLISH_TARGET=
PUBLISH_SSH_KEY=
AUTO_DEPLOY_HOSTS=
AUTO_DEPLOY_SSH_KEY=
```

## 4. Validate repository scripts

```sh
cd /opt/opn-rustproxy/packaging
./scripts/check.sh
```

## 5. First build

```sh
sudo /usr/local/sbin/rustproxy-opnsense-hourly 2>&1 | sudo tee -a /var/log/rustproxy-opnsense-builder.log
```

The first run downloads the RustProxy Git checkout and the FreeBSD 15.1 sysroot, then builds the Docker image. Later runs reuse Docker/Cargo caches. RustProxy's build also downloads crates and pinned Swagger UI assets, so the builder needs outbound HTTPS access.

Follow the log with:

```sh
sudo tail -f /var/log/rustproxy-opnsense-builder.log
```

## 6. Verify output

```sh
cd /opt/opn-rustproxy/packaging
cat dist/BUILD-INFO.txt
cat dist/SHA256
file dist/docker-build/rust-proxy
zstd -dc dist/os-rustproxy-latest.pkg | tar -tf - | head -50
```

The package payload should contain files such as `/usr/local/sbin/rust-proxy` and must not contain directory entries such as `/usr/` or `/usr/local/`. The build fails automatically when payload paths differ from `+MANIFEST`.

The binary should identify as an x86-64 FreeBSD ELF executable, not a Linux executable.

## 7. Install on a test OPNsense

Copy the package and installer:

```sh
scp dist/os-rustproxy-latest.pkg root@OPNSENSE_IP:/tmp/
scp deploy/opnsense/install-direct.sh root@OPNSENSE_IP:/tmp/
```

Then:

```sh
ssh root@OPNSENSE_IP
sh /tmp/install-direct.sh /tmp/os-rustproxy-latest.pkg
```

Open **Services -> RustProxy**, enable it and click **Apply**.

Useful checks on OPNsense:

```sh
pkg info os-rustproxy
file /usr/local/sbin/rust-proxy
service rustproxy status
tail -f /var/log/rustproxy/rustproxy.log
```

## 8. Hourly scheduler

`/etc/cron.d/rustproxy-opnsense` runs at minute 17 each hour:

```text
17 * * * * root /usr/local/sbin/rustproxy-opnsense-hourly >> /var/log/rustproxy-opnsense-builder.log 2>&1
```

No rebuild occurs when both Git SHAs are unchanged. A failed build does not advance the successful-state marker and will be retried later.

## 9. Optional test-firewall auto deploy

Only for explicitly named test firewalls:

```text
AUTO_DEPLOY_HOSTS="root@10.0.0.10"
AUTO_DEPLOY_SSH_KEY=/root/.ssh/opnsense_test
```

Leave both empty for manual deployment.

## OPNsense runtime settings

After installation open **Services -> RustProxy**. Defaults are:

- HTTP bind address / port: `0.0.0.0` / `8080`
- HTTPS/TLS enabled: yes
- HTTPS/TLS bind address / port: `0.0.0.0` / `8181`
- Admin bind address / port: `0.0.0.0` / `9090`
- Allow remote admin: yes

The RustProxy administration UI is reachable from other hosts by default on port `9090`, subject to OPNsense firewall rules. Use **Open RustProxy Admin** after Apply to open the panel in a new browser tab. If the admin bind address is `0.0.0.0`, the button uses the hostname or IP address through which you opened OPNsense.

Direct `pkg add` is supported: the package post-install script restarts OPNsense `configd`, flushes the plugin cache and renders `/usr/local/etc/rustproxy/opnsense.conf` so `configctl rustproxy status/start/stop` is available immediately. If **Enabled** is set, the post-install hook also restarts RustProxy automatically after `pkg upgrade` or `pkg add -f`.

FreeBSD uses jemalloc, so the OPNsense rc.d service sets `MALLOC_CONF=narenas:2`. This is the FreeBSD equivalent of the low-arena intent behind Linux `MALLOC_ARENA_MAX=2`; the glibc variable is intentionally not exported on OPNsense. Set `rustproxy_malloc_conf` in rc.conf to override or disable it.

RustProxy requires its data directory to be private. On OPNsense/FreeBSD the plugin runs the service as `root` and enforces owner `root:wheel` with mode `0700` on `/var/db/rustproxy` before every start.

## FreeBSD patch set

The OPNsense builder automatically applies version-specific RustProxy patches to a temporary build copy only. The application checkout remains clean:

```bash
cd /opt/opn-rustproxy/source/RustProxy
git status
```

For RustProxy 0.20.0 the builder uses:

```text
builder/freebsd/patches/0.20.0/0001-opnsense-build.patch
```

The normal setting is:

```bash
APPLY_FREEBSD_PATCHES=1
```

During a build you should see:

```text
Applying FreeBSD/OPNsense patch set for RustProxy 0.20.0 to isolated build source...
  applied: 0001-opnsense-build.patch
```

## Runtime directory

`/var/run/rustproxy` is created automatically as `root:wheel` with mode 0750 during package installation and before each service start. PID files are `daemon.pid` and `rustproxy.pid` inside that directory.
