The Docker image for Lita is intended for deploying a Lita code repository. Depending on what you're trying to do, using the Docker image may not be the right choice. The image is documented in the README at https://github.com/litaio/docker-lita
, with more detailed deployment instructions at https://docs.lita.io/getting-started/deployment/
. If you can provide some more specific information about what you're trying to achieve and what command you're running to do it, I can offer more specific suggestions.
