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?

It looks you have you some themes in your workspace, so removing those will allow you to export without an Internet connection.

[VAndreasKrauss]

Thank you very much for pointing this out. The workspace contained theme default. I removed it and it works now.

Just a suggestion: the information about the required internet access is only contained in structurizr lite/FAQ. The CLI is missing such an FAQ section and I did not assume that this answer also is valid for the CLI. Maybe, it would be a good idea to connect them or make clear that the FAQ is about both? However, it was my mistake to assume that theme default would not require an internet connection, since the documentation of theme keyword clearly states that default can be used as an URL.

Best regards & have a nice day 🌞
