Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

Apache Camel Karavan is a low-code data integration platform that simplifies Apache Camel development through visual design and rapid deployment of integration microservices. The DevMode container provides an enhanced development environment with:

• JBang Integration: Run Apache Camel routes directly using JBang without complex setup
• Enhanced Diagnostics: Trace windows showing Exchange Body, Headers, Properties, and variables
• Live Development: Automatically monitors and reloads Camel routes from the /karavan/code directory
• Maven & Java 21: Pre-configured with Maven 3.9 and OpenJDK 21 for building integrations
• Hot Reload: Changes to route definitions are automatically detected and applied

This image is comparable to the upstream Apache Camel Karavan DevMode image.

Getting Started

Running with Docker

The simplest way to start developing with Karavan DevMode is using Docker with a volume mount:

# Create a directory for your Camel routes
mkdir -p karavan-code

# Create a simple test route
cat > karavan-code/test-route.yaml <<'EOF'
- route:
    from:
      uri: "timer:tick?period=5000"
      steps:
        - log:
            message: "Hello from Karavan DevMode! Time: ${date:now:yyyy-MM-dd HH:mm:ss}"
EOF

# Run the container with your routes
docker run -d --name karavan-devmode \
  -v $(pwd)/karavan-code:/karavan/code:rw \
  -p 8080:8080 \
  cgr.dev/ORGANIZATION/apache-camel-karavan-devmode:latest

# View the logs to see your route running
docker logs -f karavan-devmode

Deploying to Kubernetes

Deploy Karavan DevMode to Kubernetes using the upstream manifests:

# Clone the Karavan repository
git clone https://github.com/apache/camel-karavan.git
cd camel-karavan/docs/install/karavan-kubernetes

# Apply the base Karavan resources
kubectl apply -f secret.yaml -f service-account.yaml -f role.yaml -f role-binding.yaml -f service.yaml

# Set the devmode image to use Chainguard
yq eval ".spec.template.spec.containers[0].env += [{\"name\": \"KARAVAN_DEVMODE_IMAGE\", \"value\": \"cgr.dev/ORGANIZATION/apache-camel-karavan-devmode:latest\"}]" -i deployment.yaml

# Apply the deployment
kubectl apply -f deployment.yaml

Validate the deployment:

# Check pod status
kubectl get pods -l app=karavan

# View logs
kubectl logs -l app=karavan -f

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
