Deploy Hubot with OpsWorks.md

Procedure

1. Create a new custom cookbook for Hubot
2. Create a Node.js stack and an app on OpsWorks
3. Set the recipe in "Deploy" section

Custom Cookbook for Hubot

Put two files as below:

• hubot/recipes/deploy.rb
• hubot/templates/default/bin_hubot.erb

hubot is the name of cookbook for example. See deploy.rb and bin_hubot.erb in this Gist for the details.

Usage

Set the following environment variables:

• BOT_NAME
• BOT_ADAPTER

[Appx.] Use New Version of Node.js

OpsWorks built-in recipe installs very old version of Node.js as of Apr. 14th 2017. To use a new version of Node.js, set the following recipe on "Setup" section.

• redguide/nodejs

deploy.rb

# _/_/_/_/ This recipe must be executed after `deploy::nodejs` built-in recipe _/_/_/_/

user = node[:deploy][:hubot][:user]
group = node[:deploy][:hubot][:group]
home = node[:deploy][:hubot][:home]
deploy_dir = node[:deploy][:hubot][:deploy_to]
environment_variables = node[:deploy][:hubot][:environment_variables]

execute "delete_monitjc_created_by_opsworks_built-in_recipe" do
  command "rm -f #{node.default[:monit][:conf_dir]}/node_web_app*"
end

  variables(
    deploy_dir: deploy_dir,
    bot_adapter: environment_variables[:BOT_ADAPTER],
    bot_name: environment_variables[:BOT_NAME],
  )
end

execute "start_hubot" do
  cwd "#{deploy_dir}/current"
  user user
  group group
  command "bin/hubot"
  environment(
