Best way to install Capistrano Slack intergration is via Bundler.
Add the following to your Gemfile, then run the bundle command to install the gem direct from the git repository
gem 'capistrano-slack', :git => 'https://github.com/j-mcnally/capistrano-slack.git'
Once installed you can use the settings below in your Capistrano deploy.rb to configure Slack.
#in deploy/shared.rb add
require 'capistrano/slack'
#in deploy.rb
# required
set :slack_token, "webhook_token" # comes from inbound webhook integration
set :slack_room, "#general"
set :slack_subdomain, "kohactive" # if your subdomain is kohactive.slack.com
before 'deploy', 'slack:starting'
after 'deploy', 'slack:finished'
# optional
set :slack_application, "Rocketman"
set :slack_username, "Elton John"
set :slack_emoji, ":rocket:"
set :slack_deploy_defaults, false #gem provides the standard before and after callbacks deploy:starting and deploy:finished deploy of set to false and provide your own.
#example slack:starting and slack:finished are the only defaults provided in the gem. You can obtain your webhook_token from the integrations section of the team page in Slack.
