I have two rails apps on the same server, let's call them A and B.
I am trying to have app A restart app B via app B's own capistrano task. Unfortunately, even after cd-ing to app B's directory, it is trying to run app A's capistrano instead. Am I missing something?
example code
system("cd /apps/appB/current && pwd && bundle exec cap:restart")
pwd correctly returns the path of appB (/apps/appB/current), however, in there is a traceback for cap:restart. This is because it is still trying to run the cap command in the context of appA, e.g.
/apps/appA/shared/bundle/ruby/1.9.1/gems/capistrano-2.15.4/lib/capistrano/configuration/loading.rb:152:in 'require': cannot load such file -- airbrake/capistrano (LoadError) from /apps/appA/shared/bundle/ruby/1.9.1/gems/capistrano-2.15.4/lib/capistrano/configuration/loading.rb:152:in 'require'.
I tried without 'bundle exec', and have tried some other ways of making system calls. I also created a bash script in another directory and tried to run it that way.
All methods described exhibit the same behaviour.
Your help would be greatly appreciated =)
You need to use Bundler.with_clean_env to ensure that your subprocess doesn't pick up your current Bundler environment:
Bundler.with_clean_env do
system("cd /apps/appB/current && pwd && bundle exec cap:restart")
end
This is essentially the same problem as Install bundle of gem within other rails application
