Creating linked_dirs in Capistrano 3 fails

I am attempting to set up Capistrano with a SilverStripe build and am running into a few troubles setting up the shared directories.

I set the linked_dirs in deploy.rb with the following:

set :linked_dirs, %w{assets vendor}

Since adding this line I get the following error:

[617afa7f] Command: /usr/bin/env mkdir -p /var/www/website/releases/20160215083713 /var/www/website/releases/20160215083713

INFO [3016a8cd] Running /usr/bin/env ln -s /var/www/website/shared/assets /var/www/website/releases/20160215083713/assets as [email protected]

I am a mega noob when it comes to Capistrano and a semi noob when it comes to server configuration and permissions, so any pointers would be appreciated.

It probably hasn't actually failed. One thing to know about Capistrano is that (success) and (failed) are actually returning the result of the exit status, (success) if 0 and (failed) if non-0.

If we look at the command in question, it says that /usr/bin/env [ -L /var/www/website/releases/20160215083713/assets ] failed. This command is saying "return 0 if /var/www/website/releases/20160215083713/assets exists and is a link (-L). This fails, but that just means it returns non-0, thus the link needs to be created. Note that the next command also fails (-d) with asserting that the path is a directory. And the last line in your output is actually creating the link in question.

You can see the test in the Capistrano codebase here: https://github.com/capistrano/capistrano/blob/master/lib/capistrano/tasks/deploy.rake#L128

You can clean up and simplify the output with https://github.com/mattbrictson/airbrussh. This is developed by one of the primary Capistrano devs.

As a sidenote, similarly all the green text in your terminal is stdout and the red text is stderr. This can also be confusing.
