Support a default Boundary Controller URL

[lorellalou]

Is your feature request related to a problem? Please describe.
I wish to deploy the Boundary Desktop in my environment with a default Boundary Controller URL. The idea is to provide to my customers a package that is ready to use.

Describe the solution you'd like
Provide in a configuration file or anything else the default Boundary Controller URL.

Describe alternatives you've considered
I have tried to modify the Boundary Desktop code but it's not easy to build, especially in our CI-CD based on Linux for a Windows target.

Explain any additional use-cases
Providing a ready to use packaging of Boundary Desktop can be a really nice feature of the product. I already manage on my side a CI-CD MSI packaging that works for Boundary Desktop that I can share with you. Maybe only specifying the Default Boundary Controller on the command line can be a quick-win implementation.

Good morning @lrolaz and thanks for trying out Boundary!

This is definitely doable, and we're looking into it. Thank you for the suggestion and be on the lookout for updates here!

May we can reuse here the BOUNDARY_ADDR environment variable, which is supported by the boundary cli.
