# Client builds on Jenkins The `Jenkinsfile` at the repo root builds the DorkNet clients on your existing Jenkins. The builds run on a **build agent**, not on Jenkins itself: - **The agent:** a container built from `ci/jenkins/Dockerfile`, which is the Jenkins inbound agent plus Python with LIEF, the .NET SDK, the Android NDK and build-tools, apktool, restic and rclone. It runs on Coolify next to Jenkins and connects to it over WebSocket on Docker's internal network. The job runs on it through the `dorknet-builder` label. - **Jenkins itself:** stays on the stock image and runs no builds. Each build is published to the **downloads bucket** under a name players can read, and the same files are kept as Jenkins artifacts (`out/downloads/2023.03/`). The DorkNet server offers them on its site: the **Downloads** page, and **Latest build** on the **Quest** page (`docs/deploy.md` → Client downloads). | Download | What it is | Built from | |---|---|---| | `DorkNet-2023.03-PC-Full.zip` | the stock Steam build with the patcher applied and your config; ready to run | `tools/build_pc.py client` → `dorknet-client-march_2023_03_21.zip` | | `DorkNet-2023.03-PC-Patch.zip` | MelonLoader, mod, config template, Steam stub, `manifest.json`; no game files | `tools/build_pc.py patcher` → `dorknet-clientpatch-march_2023_03_21.zip` | | `DorkNet-2023.03-Quest.xapk` | patched APK + OBB, for the browser installer or SideQuest | `DorkNet.Quest/scripts/build.py build` → `DorkNet-Quest-/DorkNet-.xapk` | | `DorkNet-2023.03-Quest-Installer.zip` | `install.cmd` / `install.ps1` / `install.sh` + README, unzipped next to the `.xapk` | the same package folder | The build scripts keep their own names: the launcher downloads `dorknet-clientpatch-.zip` from GitHub Releases by that exact name. `ci/downloads/publish.py` renames only the published copies. The full PC client and the Quest packages contain game files. Keep the bucket internal and the site behind an access proxy; don't publish them anywhere public. ## Where the stock builds come from The stock builds live in restic repositories on the archive FTP. They are the same repositories as the local archive's `v2/steam-v2` and `v2/quest-v2`. restic reaches the FTP through its rclone backend (`ci/jenkins/archive-restore.sh`). A build is picked by **snapshot tags**: | Repository | Tags (examples) | |---|---| | Steam | `manifest=`, `date=…`, `branch=public` | | Quest | `version=20230317`, `version-code=2128210` | The job defaults to the builds this branch targets: Steam manifest `7490748483298966814` (2023-03-21) and Quest `version-code=2128210`. Any other build can be chosen per run. Tick **LIST_SNAPSHOTS** to print the snapshots matching a filter without building anything. A restored snapshot is cached on the agent's `dorknet_cache` volume, so each stock build is downloaded once. A Quest build needs a resolved hook table for its versionCode, committed under `DorkNet.Quest/targets/`. Only `20230317-2128210.json` exists today. The build checks the table against the APK's `libil2cpp.so` and stops on a mismatch. Resolve a table for another build locally with `build.py build --dump-cs`. ## Triggers - **Push** to the branch (GitHub webhook) rebuilds only what changed: - `DorkNet.ClientMod/` and the PC scripts rebuild PC; - `DorkNet.Quest/` rebuilds Quest; - `Jenkinsfile` and `ci/jenkins/` rebuild both. - **Build with Parameters** runs a manual build: - `PLATFORMS` (both / pc / quest), and `PC_FULL_CLIENT` for the full PC client; - snapshot tags, and per-run repository overrides; - `PUBLISH_DOWNLOADS` (on by default) to publish to the downloads bucket. Push builds publish too, but only the platform they rebuilt: the manifest keeps the other platform's last files. ## Setup ### 1. Jenkins itself The controller is `ci/jenkins/docker-compose.yml`: stock Jenkins, no build tools. On Coolify, deploy it as a Docker Compose application from this repository (base directory `/ci/jenkins`), or paste it into a Compose service. - **Java 25.** The file defaults to `jenkins/jenkins:lts-jdk25`; set `JENKINS_IMAGE` to pin a version, e.g. `jenkins/jenkins:2.587-jdk25`. Jenkins supports Java 25 until September 2029, Java 21 only until September 2027, and Java 17 not at all. Keep the agent on the same Java major version; its image defaults to Java 25. - **`restart: unless-stopped`** is in the file: a restart from the Jenkins UI exits the container with code 5 and relies on Docker to start it again. - **Turn on "Connect to predefined network"** (Advanced) so the agent can reach Jenkins by its container name, `jenkins-`. - **Run no builds on it:** **Manage Jenkins → Nodes → Built-In Node → Configure**, set **Number of executors** to `0`. Earlier versions of this file built the controller from `ci/jenkins/Dockerfile`, which is now the agent's image. The service and data volume keep their names, so an existing Jenkins deployed from this file keeps its jobs and credentials when redeployed; it switches to the stock image, and its builds wait until the agent (step 3) is connected. That redeploy also upgrades Jenkins, and from Java 17 (the old default) to Java 25, unless `JENKINS_IMAGE` pins your current image. Before it: 1. **Back up the data volume** (`jenkins_home`), e.g. with a Coolify volume backup or `docker run --rm -v :/v -v "$PWD":/b alpine tar czf /b/jenkins_home.tgz -C /v .`, so you can go back to the old image. 2. After it starts, open **Manage Jenkins**. Plugins that need a newer version show up there as failed to load; update them under **Plugins → Updates** and restart. 3. Run the job once (**LIST_SNAPSHOTS** is a quick check) before relying on it. ### 2. The agent node **Manage Jenkins → Nodes → New Node**, a permanent agent: | Setting | Value | |---|---| | Name | `dorknet-builder` | | Labels | `dorknet-builder` | | Remote root directory | `/home/jenkins/agent` | | Launch method | Launch agent by connecting it to the controller, with **Use WebSocket** ticked | | Number of executors | 1 | Save, open the node, and copy its **secret**. ### 3. Deploy the agent on Coolify 1. **Create a Docker Compose application** from this repository: build pack Docker Compose, base directory **`/ci/jenkins`**, compose location **`/docker-compose.agent.yml`**. The base directory is the build context, so with `/` the build would pick up the server's `Dockerfile` at the repo root. It needs no domain. Under Advanced, turn on **Connect to predefined network**. 2. **Set its environment:** | Variable | Value | |---|---| | `JENKINS_URL` | Jenkins' **internal** address, `http://jenkins-:8080/`. Not the public URL, which is behind Cloudflare Access. | | `JENKINS_SECRET` | the node secret from step 2 | | `JENKINS_AGENT_NAME` | optional, default `dorknet-builder` | | `ARCHIVE_PC_REPO` | Steam repository folder on the FTP, e.g. `Rec Room Versions/steam-v2` (plain text, not URL-encoded) | | `ARCHIVE_QUEST_REPO` | Quest repository folder, e.g. `Rec Room Versions/quest-v2` | | `ARCHIVE_FTP_TLS` | `explicit` (default), `implicit` or `none` | | `DOWNLOADS_S3_ENDPOINT` | the downloads bucket's S3 API, internal address, e.g. `http://garage-:3900` | | `DOWNLOADS_BUCKET` | its name, e.g. `dorknet-downloads` | 3. **Deploy.** The first image build downloads the Android NDK (~1.5 GB) and takes a while. The node shows as connected in Jenkins once the agent is up. Both Jenkins and the agent join the server's predefined Coolify network, so the agent reaches Jenkins by container name. Check the name under the Jenkins service's containers before using it. ### 4. Plugins The job needs these plugins: - Pipeline - Git - GitHub (for the push trigger) - Credentials Binding - Timestamper - AnsiColor - Workspace Cleanup Most are part of the suggested set. ### 5. Credentials Add these under **Manage Jenkins → Credentials**, with exactly these IDs: | ID | Kind | Value | |---|---|---| | `archive-ftp` | Username with password | the FTP login | | `archive-ftp-host` | Secret text | FTP host name only (no `ftp://`, no user, no path) | | `archive-restic-password` | Secret text | the archive's restic password | | `quest-keystore` | Secret file | the Quest signing keystore | | `quest-keystore-password` | Secret text | its store/key password | | `clientmod-config` | Secret file | your `dorknet-clientmod.json` | | `quest-config` | Secret file | your `dorknet-quest.cfg` | | `downloads-s3` | Username with password | S3 key for the downloads bucket: access key ID / secret. Give it read and write on that bucket only. | **Use the keystore your players' installs were signed with**, the `dorknet-debug.keystore` from your earlier local builds (password `dorknet`). A different key means every player has to uninstall before installing a CI build. ### 6. The job 1. Create a **New Item → Pipeline** (e.g. `dorknet-client`). 2. Under **Pipeline**, choose **Pipeline script from SCM**: - Git URL `https://github.com/DorkSquadRR/DorkNet.git` - branch `*/march-2023-03-21` - script path `Jenkinsfile` 3. Under **Triggers**, tick **GitHub hook trigger for GITScm polling**. 4. Run it once with **Build** so Jenkins learns the parameters. Later runs offer **Build with Parameters**. ### 7. GitHub webhook In the repository's **Settings → Webhooks**: - Payload URL: `https:///github-webhook/` - Content type: `application/json` - Events: just the push event ### 8. The downloads bucket `publish.py upload` puts the files and a `manifest.json` describing them in an S3 bucket. The DorkNet server reads that bucket over HTTP on the internal network and offers the files on its site (`docs/deploy.md` → Client downloads), so the bucket needs no public route. With Garage (the S3 store on the Coolify server): 1. **Bucket and key.** Create the bucket, turn on Garage's website access for it (the server reads it through the web endpoint, port `3902`, which picks the bucket by the request's Host header), and give Jenkins a key for that bucket only: ```sh garage bucket create dorknet-downloads garage bucket website --allow dorknet-downloads garage key create jenkins-downloads garage bucket allow --read --write --key dorknet-downloads ``` Store the key as the `downloads-s3` credential. 2. **Server.** Point the DorkNet server at the web endpoint: `DorkNet__Downloads__BaseUrl=http://garage-:3902` and `DorkNet__Downloads__Host=dorknet-downloads`. Each release keeps one copy of each file; a new build overwrites it. The manifest is uploaded last, so the site only ever lists files that are fully uploaded. ### Disk The agent's `dorknet_cache` volume holds the restored stock builds, several GB each. Jenkins keeps the artifacts of the last 3 runs, on its own volume.
