There is a known bug that prevents sidekiq from starting when pty is true on Capistrano 3.

set :pty,  false

Multiple processes

You can configure sidekiq to start with multiple processes. Just set the proper amount in sidekiq_processes.

You can also customize the configuration for every process. If you want to do that, just set sidekiq_options_per_process with an array of the configuration options that you want in string format. This example should boot the first process with the queue high and the second one with the queues default and low:

set :sidekiq_options_per_process, ["--queue high", "--queue default --queue low"]

Different number of processes per host

You can configure how many processes you want to run on each host next way:

set :sidekiq_role, [:sidekiq_small, :sidekiq_big]
set :sidekiq_small_processes, 1
set :sidekiq_big_processes, 4
server 'example-small.com', roles: [:sidekiq_small]
server 'example-big.com', roles: [:sidekiq_big]

Customizing the monit sidekiq templates

If you need change some config in redactor, you can

bundle exec rails generate capistrano:sidekiq:monit:template

If your deploy user has no need in sudo for using monit, you can disable it as follows:

set :sidekiq_monit_use_sudo, false
