In my usage scenario, NextCloud has two access methods: private and public, so I need to customize the domain name section in the shared link to point to a domain name for offloading, and jump to the private domain name when the intranet link is available, and vice direction to the public domain name.

The offload part has nothing to do with nextcloud, I have implemented the relevant functions. Now, I need to change the shared link to the domain name I want to use for triage, but I haven't found a workaround.

I found the overwrite.cli.url parameter, but this parameter seems to have a big limitation, it doesn't work in a container environment and reading the description, I think this parameter is only used during development and debugging.

I need a parameter to customize the domain name I share the link with. I can try to make modifications, here are two ideas for modifications.

Describe the solution you'd like
I can try to make modifications, here are two ideas for modifications.

1. Expand the application of overwrite.cli.url to all startup methods.
2. Add new parameters for control.

The main modification location is: https://github.com/nextcloud/server/blob/master/lib/private/URLGenerator.php#L261

Additional context
https://github.com/nextcloud/server/issues/27240

Start with lib/private/URLGenerator.php around line 261 and review how overwrite.cli.url is currently applied. Compare the requested private and public shared-link behavior with the context in issue #27240. Done means a defined configuration can make shared links use the intended domain, including the reported container startup scenario.
