Error with pre-create check: "Parallels Desktop edition could not be fetched!" #91

Closed tstromberg closed 4 years ago

This happens with both docker-machine and minikube:

%  docker-machine create --driver=parallels prl-dev                                                                                                                                                                                              Creating CA: /Users/tstromberg/.docker/machine/certs/ca.pem

Error with pre-create check: "Parallels Desktop edition could not be fetched!"

Looking at the code - the parsing appears to be made here:

https://github.com/Parallels/docker-machine-parallels/blob/ae235d0689e70542f27c6a327596983389579485/parallels_darwin.go#L783

Here is what I believe the underlying command output is:

% prlsrvctl info --license
Searching for installed licenses...
No licenses installed.

I just downloaded a demo of Parallels to help a minikube user out, so I do not have a license. May I suggest that, if a license is required, that the error message be updated to show something like:

docker-machine-parallels requires a Parallels license to be purchased: https://www.parallels.com/

Alternatively, if this is just the case of a regular expression changing, I thought you should know.

The appropriate workaround I found was to select Account & License... in the Parallels menu. Add a user, and select a 14-day trial. Then a license showed up and docker-machine + minikube could run as expected.

The error message should be updated to contain this information.

@tstromberg Thank you for pointing on this! I agree - we should update the error message and make it more helpful 👍
