I am trying to connect to a mysql service on cloudfoundry. I installed vmc v 0.4.7 (which is currently the latest). I have deployed my grails application and created a mysql service through it also. Now I want to access the mysql service. I tried to perform the steps as listed here:
http://docs.cloudfoundry.com/tools/vmc/caldecott.html
I installed caldecott also. But when i do vmc tunnel I get a response saying that I need to install the tunnel-vmc-plugin. I did that, and tunnel-vmc-plugin (v 0.2.0) got installed.
Now when I do vmc tunnel I get an error saying that there is a conflict between cfoundry 0.4.21 (which is required by vmc 0.4.7) and cfoundry 0.5.0 (which is required by tunnel-vmc-plugin 0.2.0). If I try to uninstall any one cfoundry, the other gems that need that particular cfoundry version go haywire.
If you go to the git repository for tunnel-vmc-plugin at https://github.com/cloudfoundry/vmc-plugins/blob/master/tunnel/tunnel-vmc-plugin.gemspec you will see there is a tiny link that asks you to bump cfoundry to 0.5.0

How can I do this? Read a lot on the web about gem files, etc. but I have never learnt ruby and very little information about vmc plugins also.

At the moment the easiest way to resolve this is to install the pre release version by using the --pre switch with gem;

gem install vmc --pre

  • hi .. thanks for the reply. i ran the above command but now i get an error saying `Unable to resolve dependencies: vmc requires cfoundry (< 0.6, >= 0.5.1.rc5), manifests-vmc-plugin (~> 0.6.2.rc1), tunnel-vmc-plugin (~> 0.2.1.rc3)`. And the latest version of cfoundry is 0.5.0! – Arturo Mar 04 '13 at 08:15

Finally did it.

Yes the trick is to do gem install vmc --pre but every dependency that this vmc needs also needs to be installed with the --pre.
Amazingly, I searched and searched and searched and NO WHERE on the ENTIRE WEB is this specifically mentioned. For the rest of you who are stuck, first uninstall all the following gems:
- cfoundry
- tunnel-vmc-plugin
- manifests-vmc-plugin
- mothership
- caldecott-client
- caldecott
- vmc


Once you have done this, then reinstall each one of the above plugins with the --pre command. Eg
gem install cfoundry --pre
Please update the documentation Burt Beckwith and others who are working to build cloud foundry! Newbies like me who know nothing of ruby have a real hard time setting things up!
