How do I set environment variables in Capistrano 3?

Question

In Capistrano 2, you could do something like this:

set :default_environment, {
  'PATH' => '$PATH:/opt/rubies/ruby-2.1.1/bin'
}

Is there an equivalent in cap 3?

"'PATH' => 'PATH=$PATH:/opt/rubies/ruby-2.1.1/bin'" should be "'PATH' => '$PATH:/opt/rubies/ruby-2.1.1/bin'", right? — Fumisky Wells, Jul 18 '18 at 09:52

use:

set :default_env, {
  'PATH' => 'PATH=$PATH:/opt/rubies/ruby-2.1.1/bin'
}

as of at least capistrano 3.1

Where do these get saved on the server? – Richard Peck Jun 02 '14 at 07:10

@RichPeck I am actually unsure about this, and from looking around a little, I don't see where they are saved. – Mike H-R Jun 02 '14 at 10:20

I think they're set as `SHELL` variables - which means they exist for the period of the session – Richard Peck Jun 02 '14 at 11:05
@MikeH-R are you missing a comma? Shouldn't it be `set :default_env, { 'PATH' => 'PATH=$PATH:/opt/rubies/ruby-2.1.1/bin' }` – richsinn Aug 11 '14 at 23:11

Should be 'PATH' => 'new_path:$PATH', i.e. do not include PATH=... in the right-hand part – Christer Fernstrom Feb 25 '18 at 18:25

Perhaps a bit late but...

Capistrano 3 uses a specia syntax for environment

on roles :app do
  with some_env: "foobar" do
    ...
  end
end

In the above example, within the with/end block capistrano sets the environment variable SOME_ENV to "foobar"
