Custom gemset RVM

Question

I want to create my own gemset for my application. Gems installed and using from local dir(app/vendor/bundle/...)

When I try to execute:

rvm gemset create myapp

it's creating new gemset.

But how I can create new gemset based on already installed gems?

Update: @marat

Almost. But in your example you already had created gemset @rails4 before, right? And you can copy it for another version on ruby.

In my case I haven't installed gems in system, respectively I haven't gemset and can't copy it. Point is - gems are not placed on host, everything stored in deb package(in directory with app) which created by jenkins. And I need to create gemset which will be linked to app/vendor/bundle/...

Answer 1

You can copy your current gemset.

$ rvm gemset copy 2.1.1@rails4 2.1.2@rails4

UPDATE

Create new gemset

rvm gemset create jenkins_gems

Delete gems folder from that created gemset folder

rm -rf ~/.rvm/gems/ruby-2.3.1@jenkins_gems/gems

Then make symlink ~/.rvm/gems/ruby-2.3.1@jenkins_gems/gems pointing to your gems folder app/vendor/bundle

ln -s app/vendor/bundle ~/.rvm/gems/ruby-2.3.1@jenkins_gems/gems

Caveat: your ruby version may be different so change you path respectively.
