CheckYourSSeLf

A friendly Slack bot that checks your Amazon AWS accounts, and remote urls for expiring SSL certificates.

How does it work?

• The bot retrieves a list of all IAM Server Certificates from each configured AWS account, and each remote url.
• Every certificate is then parsed to see how many days are left until expiration.
• Certificates that fall below the configured warning threshold will trigger an alert.
• The results get posted to Slack.

How do I use it?

1. Clone this repository.
2. Create a copy of the sample configuration file and modify it to suit your needs.
   • cp config.yml.sample config.yml
   • text-editor-of-your-choice config.yml
3. Choose a home for the bot, and copy it there. Ruby and Bundler are the only requirements.
   • ssh deploy@slackbot-server 'mkdir -p /opt/checkyoursself'
   • scp CheckYourSSeLf.rb config.yml Gemfile Gemfile.lock deploy@slackbot-server:/opt/checkyoursself
4. Install the bundle.
   • ssh deploy@slackbot-server 'cd /opt/checkyoursself && bundle install --deployment'
5. Run the bot once to make sure everything is working properly.
   • ssh deploy@slackbot-server 'cd /opt/checkyoursself && ruby CheckYourSSeLf.rb'
6. Set up a crontab entry to run the bot on a regular basis.
   • ssh deploy@slackbot-server
   • crontab -e

     • A line like this would make the bot run once a day at 16:05:

       5 16 * * * cd /opt/checkyoursself && ruby CheckYourSSeLf.rb

7. That's it. No more surprises!
