Berkshelf gem listed as a requirement in cookbook gemfile

Hi Folks,
I’m noticing that the berkshelf gem is listed as a requirement in Gemfiles
of a lot of cookbooks I’ve been working with lately. I suspect that this is
bad behavior now that ChefDK is the recommended deployment method for
berkshelf. Just wanted to confirm with you all that my reasoning is correct.

Thanks,
William

chefdk includes bundler and berkshelf and the Gemfile will resolve.
Please try to resolve and report back.

I think it's OK. In some projects, it's not necessary to use a Gemfile any more.

Yo,

Sorry for the follow up.

It's worth mentioning the ChefDk includes gecode libs, pre-built, for
all supported target platforms, which greatly alleviates the
installation heat-cost of Berkshelf.

On machines where this (ChefDK) is not present and the prerequisite
environment variable and system libraries have not been configured, a
full installation of gecode from source will be automatically handled
by the gem (via bundle) installation.

Hi William,

I think both approaches are OK. Depends on whether you want to require
a specific berks version globally (via the ChefDK installation) or you
want to require a specific berks version on a per project level (via
Gemfile).

Usually I tend to prefer the Gemfile approach because it expresses and
enforces all its dependencies. On the other hand, if your README
states that you need ChefDK 0.3.5 as a dependency it's not that bad
either. It's just if your projects have different release cycles and
you don't want to update and test all of them whenever you install a
new ChefDK.

Thanks all. That's helpful background and alleviates my concern that a
Gemfile req. would not detect the ChefDK install and try to install it
elsewhere and/or reference a non ChefDK version. But I see how it could be
beneficial to still reference it for some cases.

Happy New Year!

It's problematic to compile. I mentioned this week: it requires a C++ compiler, takes hours on a modest VM or lightweight host, especially if the memory allocated is light, and it can cause other issues if the system runs out of swap and RAM.
