Custom launchSettings.json profile causes "Unable to configure HTTPS endpoint. No server certificate was specified"

Description

When creating a new standard blazor serverside (with docker) project, and adding the following to launchSettings.json:

"DockerTest": {
      "commandName": "Docker",
      "launchBrowser": true,
      "launchUrl": "{Scheme}://{ServiceHost}:{ServicePort}",
      "publishAllPorts": true,
      "useSSL": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "TEST"
      }
    }

I basically copied the entry for Docker, renamed Docker to DockerTest and added the environmentVariables

Then selecting that particular profile and run it, I get the following exception:

Happens both in Chrome and Firefox

App runs fine if I use the default Docker profile.

I tried to do what the exception said; and this is what the developer console spit out:

@Pilchie It’s a combo between the custom environment and Docker.

The way docker works from VS requires the environment to be Development. Otherwise we don’t try to probe the filesystem for the developer certificate (for security reasons).

When you use a custom environment you need to setup the certificate explicitly via config.

We have docs here and here on how to do this setup.

Hmm…

If I had three environments. Development, Staging and Production. Would that also be considered “advanced setup”? Is it so that the only valid profile that is supposed to work with docker is the Development profile? And everything else is considered “advanced” ? I find this very strange. Why even have profiles if this is the case?

As for suggestion, I will repeat a question that has gone unanswered earlier; “Further, in both articles, they try to reference this certificate on my local machine, but if I have to create these by myself locally on my machine, won’t this have to be re-done whenever someone else gets the solution to their computer?”

The suggestion you have, will that work across development machines and setups? The way I understand it is that all the developers have to export a certificate to a folder, map it to the container, then update the user-secrets…

Is this correct?
