Method #1
If you need an env var set strictly within the Chef process, you can use ENV['foo'] = 'bar' since it's a ruby process.
Method #2
If you need to set one for an execute provider, Chef exposes an environment hash:
execute 'Bootstrap the database' do
cwd "#{app_dir}/current"
command "#{env_cmd} rake db:drop db:create db:schema:load RAILS_ENV=#{rails_env}"
environment 'HOME' => "/home/#{app_user}"
user app_user
action :run
not_if %[psql -U postgres -c "\\l" | grep #{db_name}]
endCode language: PHP (php)
