Is host filtering supported?

[ruudk]

Is it possible to do a deploy only to a specific server using host filtering when this plugin is enabled?

How did you solve this issue?

[ruudk]

I monkey patched Capistrano a bit:

# Monkey Patch
module Capistrano
  module DSL
    def roles_filtered(*names)
      hosts = env.roles_for(names.flatten)
      roles = Configuration.env.filter(hosts)
      roles.map { |host| env.server(host) }
    end
  end
end

Then, whenever I use roles_filtered with HOSTS=host1,host2 bundle exec cap production deploy it will filter correctly :)

Which one file did you change these codes?

[ruudk]

I added the monkey patch to my own config.rb

@ruudk thanks for answering.

We don't get it properly where did you patch it.What is your own config.rb ? Are you mean the deploy.rb in config folder? I have tried to patch your code in deploy.rb nor configuration.rb of capistrano 3.5.0 gem,but doesnt't affect anything while trying to pass HOST env during deployment process even i set roles_filtered.

Capistrano files and directory structure:

├── Capfile
├── config
│ ├── deploy
│ │ ├── production.rb
│ │ └── staging.rb
│ └── deploy.rb
└── lib
└── capistrano
└── tasks

Could you please give more details your usage in deployment ? Thanks.

I put it in my deploy.rb :)
