Customization

Aletyx Playground can be fully customized to meet your organization’s branding, security, and development needs. This guide covers all aspects of Aletyx Playground customization, from simple branding changes to advanced features like custom accelerators and authentication providers.

Environment Setup

Before customizing Aletyx Playground, ensure you have:

Docker and Docker Compose installed
Git installed
Access to a container registry (if deploying to Kubernetes/OpenShift)
Basic understanding of environment variables and container concepts

Basic Customization

Branding

Aletyx Playground supports complete branding customization, allowing you to replace the default logos with your organization’s own branding.

Logo Customization

You can replace the following files in the container image:

Component	File Path	Specifications
Header Logo	`/kie-sandbox/app/images/app_logo_rgb_fullcolor_reverse.svg`	Fixed height of 38px
Colored Logo	`/kie-sandbox/app/images/app_logo_rgb_fullcolor_default.svg`	Fixed height of 80px
Favicon	`/kie-sandbox/app/favicon.svg`	Standard favicon format

Favicon is an .svg not a .ico

Example Dockerfile for Branding

FROM aletyx/playground:latest

# Copy your custom logo files
COPY branding/your-logo-light.svg /var/www/html/images/app_logo_rgb_fullcolor_reverse.svg
COPY branding/your-logo-dark.svg /var/www/html/images/app_logo_rgb_fullcolor_default.svg
COPY branding/your-favicon.svg /var/www/html/favicon.svg

Application Name

You can change the application name displayed throughout the UI using an environment variable:

KIE_SANDBOX_APP_NAME="Your Company Automation Studio"

Container-Based Deployment

The easiest way to set up a customized Aletyx Playground is using Docker Compose:

Create a directory for your customization project:

mkdir custom-sandbox && cd custom-sandbox

Create a docker-compose.yml file (see the Docker Compose Example section)
Create a Dockerfile for your customizations (see the Containerfile/Dockerfile Example section)
Create a branding directory with your custom logos
Start the environment:

docker compose up --build -d

Advanced Customization

Services Configuration

Aletyx Playground relies on two additional services for full functionality:

Extended Services: Provides validation and runtime capabilities for your models
CORS Proxy: Facilitates communication with external Git providers

Configure these services using environment variables:

# Extended Services URL (validation and runtime)
KIE_SANDBOX_EXTENDED_SERVICES_URL=http://extended-services:21345

# CORS Proxy URL (Git provider communication)
KIE_SANDBOX_CORS_PROXY_URL=http://cors-proxy:7081

Git Provider Integration

Aletyx Playground can integrate with various Git providers. Configure them using the KIE_SANDBOX_AUTH_PROVIDERS environment variable:

KIE_SANDBOX_AUTH_PROVIDERS='[
  {
    "id": "github_dot_com",
    "domain": "github.com",
    "supportedGitRemoteDomains": ["github.com", "gist.github.com"],
    "type": "github",
    "name": "GitHub",
    "enabled": true,
    "iconPath": "",
    "group": "git"
  },
  {
    "id": "gitlab_dot_com",
    "domain": "gitlab.com",
    "supportedGitRemoteDomains": ["gitlab.com"],
    "type": "gitlab",
    "name": "GitLab",
    "enabled": true,
    "iconPath": "",
    "group": "git"
  }
]'

GitHub Enterprise Integration

For GitHub Enterprise instances, add a custom provider:

KIE_SANDBOX_AUTH_PROVIDERS='[
  {
    "id": "github_enterprise",
    "domain": "github.mycompany.com",
    "supportedGitRemoteDomains": ["github.mycompany.com"],
    "type": "github",
    "name": "GitHub Enterprise",
    "enabled": true,
    "iconPath": "",
    "group": "git"
  }
]'

Accelerators

Accelerators allow you to quickly bootstrap projects with predefined configurations. Configure accelerators using the KIE_SANDBOX_ACCELERATORS environment variable. For more information on Accelerators see the Accelerators and Accelerators Advanced in the documentation on how to build them. To incorporate these into your build you will customize like the example:

KIE_SANDBOX_ACCELERATORS='[
  {
    "name": "Quarkus Process",
    "iconUrl": "https://raw.githubusercontent.com/yourorg/accelerators/main/quarkus-logo.png",
    "gitRepositoryUrl": "https://github.com/yourorg/process-accelerator.git",
    "gitRepositoryGitRef": "main",
    "dmnDestinationFolder": "src/main/resources/dmn",
    "bpmnDestinationFolder": "src/main/resources/bpmn",
    "otherFilesDestinationFolder": "src/main/resources/others"
  },
  {
    "name": "Quarkus Decision",
    "iconUrl": "https://raw.githubusercontent.com/yourorg/accelerators/main/dmn-logo.png",
    "gitRepositoryUrl": "https://github.com/yourorg/decision-accelerator.git",
    "gitRepositoryGitRef": "main",
    "dmnDestinationFolder": "src/main/resources/dmn",
    "bpmnDestinationFolder": "src/main/resources/bpmn",
    "otherFilesDestinationFolder": "src/main/resources/others"
  }
]'

Accelerator Structure

Each accelerator is a Git repository containing:

Project structure (src directories, pom.xml, etc.)
Configuration files
Deployment scripts
README and documentation

Each accelerator definition requires:

name: Display name shown in the UI
iconUrl: URL to an icon image (displayed in the UI)
gitRepositoryUrl: URL to the Git repository
gitRepositoryGitRef: Branch, tag, or commit to use
dmnDestinationFolder: Where DMN files should be placed
bpmnDestinationFolder: Where BPMN files should be placed
otherFilesDestinationFolder: Where other files should be placed

Custom Commit Messages

You can enforce custom commit messages and validate them against your organization’s standards:

# Require custom commit messages (instead of default ones)
KIE_SANDBOX_REQUIRE_CUSTOM_COMMIT_MESSAGE=true

# Optional: URL to a validation service
KIE_SANDBOX_CUSTOM_COMMIT_MESSAGE_VALIDATION_SERVICE_URL=http://commit-validator:8090/validate

Commit Message Validation Service

If you implement a validation service, it should:

Accept POST requests with the commit message in the body
Return JSON with:
result: Boolean (true for valid, false for invalid)
reasons: Array of strings explaining validation failures

Example response for an invalid message:

{
  "result": false,
  "reasons": [
    "Message exceeds the maximum length of 72 characters.",
    "Missing required prefix with issue number in the format: my-issue#123."
  ]
}

Editors Configuration

You can enable or disable specific editors using the KIE_SANDBOX_EDITORS environment variable:

KIE_SANDBOX_EDITORS='[
  {
    "extension": "bpmn",
    "filePathGlob": "**/*.bpmn?(2)",
    "editor": {
      "resourcesPathPrefix": "gwt-editors/bpmn",
      "path": "bpmn-envelope.html",
    },
    "card": {
      "title": "Workflow",
      "description": "BPMN files are used to generate business workflows.",
    },
  },
  {
    "extension": "dmn",
    "filePathGlob": "**/*.dmn",
    "editor": {
      "resourcesPathPrefix": "gwt-editors/dmn",
      "path": "dmn-envelope.html",
    },
    "card": {
      "title": "Decision",
      "description": "DMN files are used to generate decision models",
    },
  }
]'

Troubleshooting

Common issues and solutions:

Service Connectivity

If Aletyx Playground cannot connect to Extended Services or CORS Proxy:

Check that the services are running:

docker compose ps

Verify network connectivity:

docker compose exec kie_sandbox ping extended_services
docker compose exec kie_sandbox ping cors

Check service logs:

docker compose logs extended_services
docker compose logs cors

Git Provider Authentication

If authentication with Git providers fails:

Verify CORS Proxy is running correctly
Check the browser console for CORS-related errors
Ensure the Git provider configuration is correct in KIE_SANDBOX_AUTH_PROVIDERS

Accelerator Issues

If accelerators don’t appear or fail to apply:

Verify the Git repository URLs are accessible
Check the correct branch/tag is specified in gitRepositoryGitRef
Ensure the JSON syntax in KIE_SANDBOX_ACCELERATORS is valid

Browser Cache Issues

If changes don’t appear after updating the container:

Clear browser cache
Try incognito/private browsing mode
Rebuild and restart the container:

docker compose down
docker compose up --build -d
