Capistrano::Teams

This gem extends Capistrano functionality to push notices to Microsoft Teams via an incoming webhook.

With just the webhook url configured and the default values, the plugin registers hooks for the base deploy tasks (start, revert, finish, rollback and failed) and pushes simple notifications to the room where the used webhook was created.

This project is meant to be highly customisable, you can find all the details below.

This gem works with Capistrano v3.x+. Please check the capistrano gem version you're using before installing this gem:

 bundle show | grep capistrano

If you are new to Capistrano, check the Capistrano 3 documentation.

Installation

Add this line to your application's Gemfile:

gem 'capistrano', '~> 3.0.0'
gem 'capistrano-teams'

And then execute:

bundle install

Or install it manually:

gem install capistrano-teams

Usage

In Microsoft Teams, add an "Incoming Webhook" connector in the channel where you want to see deployment notices as described here. Copy the generated Webhook URL since you will need to add it in one of the detailed steps below.

Setup your application

Add the following line to your Capfile.

require "capistrano/teams"

In order to send notifications you must set the following options in your deploy.rb or stage file (staging.rb, production.rb, etc). The only required option is the :teams_webhook_url setting.

set :teams_webhook_url, "https://outlook.office.com/webhook/{groupId}@{tenantId}/IncomingWebhook/{connectorId}/{webHookId}"

set :teams_suppress_events, false
set :teams_message_type, Message::TYPE_CARD
set :teams_http_options, verify_mode: OpenSSL::SSL::VERIFY_PEER

To disable sending notifications for a certain stage, or to change the team/channel/room the message is posted to, you need to edit the stage file and set the following:

set :teams_suppress_events, true # Default value: false

Automated notifications

After setting the minimum options needed for your application, the plugin will push notifications to the teams room where the webhook was created for all the deploy events. Listed below you can see the hooks where the plugin injects itself:

namespace :deploy do
  before 'deploy:starting', 'teams:deploy:starting'
  before 'deploy:reverting', 'teams:deploy:reverting'
  after 'deploy:finishing', 'teams:deploy:finishing'
  after 'deploy:finishing_rollback', 'teams:deploy:finishing_rollback'
  after 'deploy:failed', 'teams:deploy:failed'
end

Custom notifications

If you want to send a custom notification you can invoke or execute the rake task teams:notify as shown below

# with invoke
Rake::Task["teams:notify"].invoke(
  "{status}", 
  [
    {"name"=>"{first_fact_name}", "value"=>"{first_fact_value}"},
    {"name"=>"{second_fact_name}", "value"=>"{second_fact_value}"},
    # ...    
  ],
  "{theme_color}"
)
# with execute
Rake::Task["teams:notify"].execute(
  Rake::TaskArguments.new(
    [:status, :facts, :theme_color],
    [
      "{status}",
      [
        {"name"=>"{first_fact_name}", "value"=>"{first_fact_value}"},
        {"name"=>"{second_fact_name}", "value"=>"{second_fact_value}"},
        # ...    
      ],
      "{theme_color}"
    ]
  )
)

Remove default hooks for an action

To remove a default hook from this plugin you can use the following line, it can be used anywhere in the desired deploy.rb or stage file

Rake::Task['teams:deploy:starting'].clear_actions
Rake::Task['teams:deploy:finishing'].clear_actions

Rake::Task['deploy:starting'].prerequisites.delete('teams:deploy:starting')

Custom Hook for rake task with arguments

If you want to create a custom hook for tasks with arguments you can use the snippet below (with both invoke and execute shown above):

before 'deploy:starting', :only => :deploy do
  Rake::Task["teams:notify"].invoke(
    "{status}", 
    [
      {"name"=>"{first_fact_name}", "value"=>"{first_fact_value}"},
      {"name"=>"{second_fact_name}", "value"=>"{second_fact_value}"},
      # ...    
    ],
    "{theme_color}"
  )
end

Message Types

You can use this plugin with two message types: Message::TYPE_BASIC or Message::TYPE_CARD

Basic message type (default)

The basic message type is the simple way to send notifications from capistrano to Teams.

set :teams_basic_message_title, 'Deployment Notice » %<application>s'
set :teams_basic_message_text, '<h1>Deploy for %<application>s' \
      ' on <strong>%<stage>s</strong> by ' \
      '<strong>%<user>s</strong></h1> ' \
      "Branch: %<branch>s \n\n" \
      'Status: %<status>s'

Card message type

The card message type has a few more options and can be configured more and can list several facts (name => value)

set :teams_card_message_title, 'Deployment Notice » %<application>s'
set :teams_card_message_sub_title, 'On %<stage>s'
set :teams_card_message_image, ''
set :teams_card_message_summary, 'Deploy for %<application>s on %<stage>s by %<user>s'
set :teams_card_message_markdown, true

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Deployment

Run deploy

cap <stage_name> deploy

You should then be able to proceed as you would usually, you may want to familiarise yourself with the truncated list of tasks, you can get a full list with:

cap -T
