Docker Deployment

You may deploy pre-built Docker images into your existing hosting environment with:

docker run -d -p 8080:8080 --restart unless-stopped cqframework/cql-translation-service:latest # or any official tag

And you're done. No environment variables or further configuration are needed. Jedi's may use your existing Kubernetes, Open Shift etc installations as you see fit. :)

To build your own image:

docker build -t cqframework/cql-translation-service:latest . # but use your your own repo and tag strings!
