Can I export to PUML from a DSL file while being offline?

Question

Hey,

At first, thanks for developing on the C4model and its graphical visualization layer. I like the kind of abstractions and try to introduce them into our team.

Therefore, I want to use the structurizr CLI in a docker image for local development and within-CI processing.
My plan was to export the JSON/DSL file in the CI pipeline to always have the most up to date graphs from the source.
While this works quite good when developing a documentation locally, the Github CI container has no internet access and throws an HttpHostConnectException.

org.apache.hc.client5.http.HttpHostConnectException: Connect to [https://static.structurizr.com:443](https://static.structurizr.com/) [static.structurizr.com/172.67.223.154, static.structurizr.com/104.21.54.48] failed: Operation timed out

Is there a way to run structurizr export from a DSL or a JSON file without having internet access? Do I need to setup further services within the image to do that? E.g., a structurizr server?
