See capistrano/sidekiq/helpers.rb for other undocumented configuration settings.

Upgrading and reconfiguring

When upgrading or reconfiguring the sidekiq_processes option you must run sidekiq:uninstall before and sidekiq:install after.

Bundler

If you'd like to prepend bundle exec to your sidekiq and sidekiqctl calls, modify the SSHKit command maps in your deploy.rb file:

SSHKit.config.command_map[:sidekiq] = "bundle exec sidekiq"
SSHKit.config.command_map[:sidekiqctl] = "bundle exec sidekiqctl"

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

Configuring the log files on systems with less recent Systemd versions

The template used by this project assumes a recent version of Systemd (v240+, e.g. Ubuntu 20.04).

On systems with a less recent version, the append: functionality is not supported, and the Sidekiq log messages are sent to the syslog.

It's possible to workaround this limitation by configuring the system logger to filter the Sidekiq messages; see wiki.
