CodeDeploy doesn’t come with a native way to integrate with third party services; so in order to integrate with a service you need to do a small workaround involving SNS and Lambda.

Setup SNS Topic and Lambda

First you need to setup a SNS Topic “deployments” (Feel free to use your own topic name). Once that is done you need to hop on over to Lambda and find a SNS blueprint, I used sns-message-python with the event SNS and then set to the topic just created.

Next setup the basic execution role recommended by AWS (if you don’t have a role setup already).

Create your Lambda Function

Below is the code I used to send a message to slack using Lambda:

1. from __future__ import print_function
2. import json, urllib, urllib2
3.  
4. def send_slack(message):
5. “””
6. Send Slack Message to Deployments Channel
7. “””
8. slack_token = ‘<api_token>’
9. slack_channel = ‘<channel_short_name>’
10. slack_user = ‘Deployment Bot’
11. slack_url = ‘https://slack.com/api/chat.postMessage’
12. payload = {
13. “token”: slack_token,
14. “channel”: slack_channel,
15. “username”: slack_user,
16. “text”: message
17. }
18. query_string = urllib.urlencode(payload)
19. url = slack_url + ‘?’ + query_string
20. response = urllib2.urlopen(url)
21.  
22. def lambda_handler(event, context):
23. message = event[‘Records’][0][‘Sns’][‘Message’]
24. send_slack(message)
25. return message

Create a Trigger on your CodeDeploy

I used the following triggers:

1. Deployment Starts
2. Deployment Succeeds
3. Deployment Fails

That’s it now everytime you deploy using CodeDeploy you can have a tracking log via Slack.

I am a huge fan of integrating slack with everything from saltstack to monitoring alerts. That way everything is in one place!
