How could I create a "nice" Capistrano deployment?

How do I set up a good index for cap:deploy

?

I want the commands to be nice on the remote server cp

:

nice -n 19 cp ...

Not sure about cp . Not using SCM?

I tried with my setup (I am using subversion) and it seems to work. In deploy.rb add:



set :scm_command, "nice -19 svn"

It seems a little more complicated, if you are not using SCM you will have to overload checkout () in deploy / scm / none.rb.

For those who want to have a good assets:precomile

job for a assets:precomile

very time consuming, the following.

namespace :deploy do
  task :map_bins_to_nice  do
    SSHKit.config.command_map.prefix[:rake]&.unshift('nice -n 19')
  end
end

Capistrano::DSL.stages.each do |stage|
  after stage, 'deploy:map_bins_to_nice'
end


Note that this makes every rake

task niced. Eg rake db:migrate

.
