# Creating Training Docker Image You can check out the sample repository to create docker images: NetBook uses these docker images as base to creating your training environment. So, we suggest not to add any CMD in your images as they get replaced by our CMDs If your docker has an entry point command, it gets automatically replaced with NetBook's entrypoint command --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://netbook-2.gitbook.io/netbook-docs/the-basics/components/experiments/creating-training-docker-image.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
