You are absolutly right. We’ve spend a lot of time to figure out this “solution”.
I think this is not a solution because it does not match to the goals, which boundary try to solve. Boundary says about itself, that it will fill the gab in dynamic enviroments to connect changing addresses.
With filling the IPAdress into an credential-library, this target is not reached, because you have to spend a lot of unnessesary time and energy to create targets matching cred-library and hosts which ip-adresses have to match the http-post-request-body… that is hard to manage.
@hashicorp: I think this is not the point you try to get. How can we dynamicaly put the IP-Adress of the host into the request?
