Company ABC used AWS CodeDeploy to deploy one web application to AWS services including EC2. CodeDeploy is running well however your manager wants to get in time notifications in Slack channel when a new deployment has succeeded or failed. You were told to implement this in AWS CloudWatch Events. The target of the Event rule would be a Lambda function that applies only to deployments. Which event pattern is correct for the rule? 

Answer options:

A.{
"source": [
"aws.codedeploy"
],
"detail-type": [
"CodeDeploy Deployment State-change Notification"
],
"detail": {
"state": [
"FAILURE",
"SUCCESS"
]
}
}
B.{
"source": [
"aws.codedeploy"
],
"detail-type": [
"CodeDeploy Instance State-change Notification"
],
"detail": {
"state": [
"FAILURE",
"SUCCESS",
"READY",
"START"
]
}
}
C.{
"source": [
"aws.codedeploy"
],
"detail-type": [
"AWS API Call via CloudTrail"
],
"detail": {
"state": [
"FAILURE",
"SUCCESS"
]
}
}
D.{
"source": [
"aws.codedeploy"
],
"detail-type": [
"CodeDeploy Instance State-change Notification"
],
"detail": {
"state": [
"FAILURE",
"START"
]
}
}
 

Correct Answer – A
CloudWatch Events rule is great to help monitor the status of CodeDeploy. Details can be found in
https://docs.aws.amazon.com/codedeploy/latest/userguide/monitoring-cloudwatch-events.html.
This scenario is a typical use case according to this document.
Option A is CORRECT: Because this case needs to monitor the status change of deployment so the “detail-type” would be "CodeDeploy Deployment State-change Notification".
Option B is incorrect: Because the "detail-type" of "CodeDeploy Instance State-change Notification" is incorrect.
Option C is incorrect: Because the "detail-type" of "AWS API Call via CloudTrail" should not be used.
Option D is incorrect: Because the "detail-type" is incorrect. Also the states of"FAILURE" and "SUCCESS" need to be included.
