DorkNet/ci/jenkins

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.

Platform	Output (Jenkins artifacts)	How
PC	out/pc/dorknet-clientpatch-march_2023_03_21.zip: MelonLoader, mod, config template, Steam stub, manifest.json; no game files	tools/build_pc.py patcher
PC	out/pc/dorknet-client-march_2023_03_21.zip: the stock Steam build with the patcher applied and your config; ready to run	tools/build_pc.py client
Quest	out/quest/dorknet-recroom-<code>.apk and out/quest/DorkNet-Quest-<ver>/ (.xapk + installers)	DorkNet.Quest/scripts/build.py build

The full PC client and the Quest packages contain game files, so keep them on Jenkins. 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=<depot manifest id>, 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.

Setup

1. Jenkins itself

Jenkins runs as a Coolify service from a Compose file:

• Use the Java 25 image, e.g. jenkins/jenkins:latest-jdk25, or 2.587-jdk25 to pin. 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.
• Add restart: unless-stopped to the jenkins service. A restart from the Jenkins UI exits the container with code 5 and relies on Docker to start it again. Without a restart policy it stays stopped.
• Turn on "Connect to predefined network" (Advanced) so the agent can reach Jenkins by its container name, jenkins-<service uuid>.
• Run no builds on it: Manage Jenkins → Nodes → Built-In Node → Configure, set Number of executors to 0.

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.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-<service uuid>: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

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

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://<your jenkins>/github-webhook/
• Content type: application/json
• Events: just the push event

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.
