# Or build and install locally
docker build --tag=ddosify/ddosify-docker-extension:latest .
docker extension install ddosify/ddosify-docker-extension:latest

Usage

Basic Load Test

1. Enter your target URL (e.g., httpbingo.org/get)
2. Select the protocol (HTTP/HTTPS) and HTTP method
3. Configure load parameters:
   • Request Count: Total number of requests
   • Duration: Test duration in seconds
   • Load Type: Linear, Incremental, or Waved
4. Click Start to run the test

Debug Mode

Click Debug to send a single request with verbose output - useful for verifying your configuration before running a full load test.

CLI Command Export

Click the terminal icon to view and copy the equivalent Docker CLI command:

docker run -it --rm ddosify/ddosify ddosify -t "https://httpbingo.org/get" -n 100 -d 10 -m GET -l linear -T 5

Advanced Options

• Headers: Add custom HTTP headers
• Request Body: Send JSON or other data with POST/PUT requests
• Basic Auth: Add authentication credentials
• Proxy: Route requests through a proxy server
• Timeout: Set request timeout in seconds

Dynamic Variables

Use dynamic variables in your URL, headers, or body:

Variable	Description	Example
{{_randomInt}}	Random integer	12345
{{_randomString}}	Random string	abc123
{{_uuid}}	UUID v4	550e8400-e29b-41d4-a716-446655440000
{{_timestamp}}	Unix timestamp	1699876543

Example: https://api.example.com/users/{{_randomInt}}

See Ddosify documentation for the full list of dynamic variables.

Tips

• Use host.docker.internal instead of localhost to test services running on your host machine
• Start with Debug mode to verify your configuration
• Use the PDF report feature to save and share test results

Publishing to Marketplace

To publish a new version to the Docker Extensions Marketplace:

1. Update Version

Update the TAG in the Makefile:

TAG?=0.3.0

2. Build and Push Multi-arch Image

make push-extension

This builds and pushes images for both linux/amd64 and linux/arm64 platforms.

4. Automatic Publishing

Extensions now go through an automated validation process. If all checks pass, the extension is published within a few hours. No manual review is required.

Notes

• The marketplace caches extensions for 12 hours. Restart Docker Desktop to force refresh.
• Only extensions listed in the marketplace can be installed by default (changeable in Docker Desktop settings).
• Extension updates are automatically downloaded and installed for users.

For more details, see the Docker Extensions Publishing Guide.
