+# Jenkins for Cloudron - Build Notes
+
+This document provides instructions for building, testing, and deploying the Jenkins package to Cloudron.
+
+## Prerequisites
+
+- Cloudron server (version 5.4.0 or higher)
+- Docker installed on your build machine
+- Cloudron CLI tool installed (`npm install -g cloudron`)
+
+## File Structure
+
+```
+jenkins-cloudron/
+├── CloudronManifest.json     # Package definition
+├── Dockerfile                # Docker image build instructions
+├── start.sh                  # Initialization script
+├── nginx.conf                # NGINX configuration
+├── supervisor.conf           # Supervisor configuration for process management
+├── logo.png                  # App icon (128x128 PNG)
+├── casc_templates/           # Jenkins Configuration as Code templates
+│   ├── default.yaml          # Default authentication config
+│   ├── ldap.yaml             # LDAP authentication config
+│   └── oauth.yaml            # OAuth/OIDC authentication config
+```
+
+## Building the Package
+
+1. Create a directory for your package and place all files in the appropriate structure.
+
+2. Download a Jenkins logo (128x128 PNG) and save it as `logo.png`
+
+3. Build the Docker image:
+   ```bash
+   cloudron build
+   ```
+
+4. Test the package locally:
+   ```bash
+   cloudron install —image cloudron/jenkins
+   ```
+
+## Authentication Configuration
+
+The package supports three authentication methods:
+
+1. **Default (Local)**: Uses Jenkins’ built-in user database
+2. **LDAP**: Uses Cloudron’s LDAP server for authentication
+3. **OAuth/OIDC**: Uses Cloudron’s OAuth service for single sign-on
+
+The authentication method is automatically configured based on the presence of environment variables provided by Cloudron.
+
+## Testing
+
+After installation, test the following:
+
+1. **Basic functionality**:
+   - Access Jenkins through your Cloudron dashboard
+   - Verify the initial admin password works
+   - Create a simple pipeline job
+
+2. **Authentication**:
+   - Test LDAP integration by enabling the LDAP addon
+   - Test OAuth/OIDC integration by enabling the OAuth addon
+   - Verify user permissions are correctly applied
+
+3. **Persistence**:
+   - Install plugins through the Jenkins UI
+   - Restart the app to verify plugins persist
+   - Check that job configurations are maintained
+
+## Troubleshooting
+
+- **Jenkins doesn’t start**: Check logs using `cloudron logs -f`
+- **Authentication issues**: Verify the correct addons are enabled and configuration is applied
+- **Permission problems**: Check the ownership and permissions of files in `/app/data`
+
+## Updating Jenkins
+
+When a new version of Jenkins is released, update the Dockerfile to pull the latest version and rebuild the package.
+
+## Additional Notes
+
+- The package uses Jenkins Configuration as Code (JCasC) to automate the setup process
+- Jenkins runs as the `cloudron` user for proper permissions
+- Files in `/app/data/jenkins_home` are persisted across restarts and updates
+- Initial admin password is set to ‘adminpass’ for local authentication
+- **Java Version**: The package uses `openjdk-17-jdk`, which is a recommended Java version for Jenkins 2.516.1 LTS.
+- **Plugin Installation**: Plugins are now installed using `jenkins-plugin-cli` during the Docker build process, which handles dependencies automatically.
+
+## Deployment to Cloudron App Store
+
+If you wish to publish your app to the Cloudron App Store:
+
+1. Update the CloudronManifest.json with your details
+2. Test thoroughly on your own Cloudron instance
+3. Follow the Cloudron App Publishing guidelines
+
+Happy CI/CD with Jenkins on Cloudron!

+# Learning Log - Gemini CLI
+
+This document records mistakes made during interactions and their corresponding solutions, aiming to improve future performance and accuracy.
+
+## Docker and File Operation Mistakes
+
+### 1. `config.yaml` not found during Docker build
+- **Mistake**: Assumed `config.yaml` would be present for `COPY` instruction in Dockerfile when it was dynamically generated by `start.sh` at runtime.
+- **Solution**: Created a placeholder `config.yaml` file in the build context to satisfy the `COPY` instruction during the Docker build process. The `start.sh` script then overwrites this placeholder with the dynamically generated content.
+
+### 2. `apt-get` permission denied during Docker build
+- **Mistake**: Encountered `E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)` during `apt-get update` or `install` in Dockerfile.
+- **Solution**: Explicitly set `USER root` before `apt-get` commands in the Dockerfile to ensure they run with necessary privileges. Also, ensured `DEBIAN_FRONTEND=noninteractive` was used to prevent interactive prompts.
+
+### 3. `chown: invalid user: 'cloudron:cloudron'`
+- **Mistake**: Attempted to change ownership of files to `cloudron:cloudron` before the `cloudron` user and group were created in the Docker image.
+- **Solution**: Added explicit `RUN groupadd -r cloudron && useradd -r -g cloudron cloudron` commands in the Dockerfile *before* the `chown` instruction to ensure the user and group exist.
+
+### 4. `docker run -it` "the input device is not a TTY"
+- **Mistake**: Attempted to run Docker containers with `-it` flags in a non-interactive environment, leading to TTY errors.
+- **Solution**: For running containers in the background, use detached mode (`-d`) and rely on `docker logs` or `docker cp` for inspecting output and files. Avoid `-it` unless a true interactive terminal session is required and supported by the environment.
+
+### 5. `replace` tool "No changes to apply" or "Expected 1 occurrence but found X"
+- **Mistake**: Provided `old_string` to the `replace` tool that either did not exactly match the target text or matched multiple times, leading to failed or unintended operations.
+- **Solution**: Always read the file content immediately before using `replace` to obtain the *exact* `old_string` (including all whitespace, indentation, and line endings). For complex blocks or when multiple matches are a risk, consider overwriting the entire file content using `write_file` if appropriate for the context.
+
+### 6. `start.sh` duplication
+- **Mistake**: Unintended duplication of script content within `start.sh` due to imprecise `replace` operations, where a section of the script was inadvertently appended to itself.
+- **Solution**: When making significant structural changes or large modifications to a script, it is safer and more reliable to read the entire file, perform the modifications in memory, and then overwrite the entire file using `write_file`.
+
+### 7. APISIX etcd connection issues (local testing)
+- **Mistake**: Presumed APISIX would run in a truly standalone mode for local testing without an etcd instance, or that `localhost` would correctly resolve to a host-exposed etcd port from within the container.
+- **Solution**: For local testing of applications with external dependencies like etcd, explicitly spin up the dependent service in a separate container. Connect the application container to the dependency container using a user-defined Docker network and refer to the dependency by its service name (e.g., `apisix-etcd`) as the hostname. This accurately simulates the Cloudron environment where addons are provided as networked services.
