Capistrano Net::SSH.start deprecating watning

Just upgraded to the latest capistrano and my rails deployments are all printing this warning -

/home/vivek/.rvm/gems/ruby-2.4.1/gems/sshkit-1.14.0/lib/sshkit/backends/connection_pool.rb:59:in `call': Passing nil, or [nil] to Net::SSH.start is deprecated for keys: user

Everything seems to be working.

I upgraded from 3.5.0 to the current release (3.91.). Is there anything that needs to be changed in deploy.rb?

When declaring your servers in e.g. config/deploy/production.rb, make sure to explicitly set a username. My guess is that you don't have one specified, hence the warning.

For example:

server "example.com", user: "deploy", roles: %w[app web]

You can test that the username is being accepted by running:

$ cap production doctor:servers

Servers (1)

    [email protected] [:app, :web]

The username for each server can also be overridden globally via :ssh_options. If you set :ssh_options, make sure those options don't include something like user: nil.

You can inspect the value of :ssh_options by running:

$ cap production doctor:variables
