Send a SNS alert from Jenkins job

1. Prerequisites

• AWS Account: You’ll need an active AWS account with permissions to create and manage SNS topics and IAM users.
• Jenkins Server: A running Jenkins server, either self-hosted or in the cloud.
• AWS Credentials: An IAM user with programmatic access to SNS.

2. Set up SNS

• Create an SNS Topic: In the AWS SNS console, create a new topic. This will be where Jenkins sends its notifications.
• Configure Access: Create an IAM user with programmatic access and grant it the necessary permissions to publish messages to the SNS topic. Securely store the access key ID and secret access key.

3. Configure Jenkins

• Install the AWS SDK Plugin: Go to “Manage Jenkins” > “Manage Plugins” and install the “AWS SDK” plugin.
• Configure AWS Credentials: In “Manage Jenkins” > “Configure System,” find the “Amazon SNS Notifier” section. Enter your AWS credentials (access key ID and secret access key) and the ARN of the SNS topic you created. You can also configure default notification behavior here.

4. Add SNS Notification to Your Jenkins Job

There are a few ways to do this:

• Using the “Amazon SNS Notifier” Post-build Action:
  • In your Jenkins job configuration, add a “Post-build Action” and select “Amazon SNS Notifier.”
  • Customize the subject and message of the notification. You can use Jenkins environment variables to include information like build number, status, etc.
  • If needed, override the default SNS topic ARN.
• Using the Pipeline AWS Steps Plugin:
  • Install the “Pipeline AWS Steps” plugin.
  • In your Jenkinsfile, use the snsPublish step:
  Groovypipeline { agent any stages { stage('Example') { steps { // Your build steps here } } stage('Notify') { steps { snsPublish topicArn: 'your-topic-arn', subject: "Jenkins Build Result for ${env.JOB_NAME}", message: "Build ${env.BUILD_NUMBER} of ${env.JOB_NAME} ${currentBuild.currentResult}" } } } }

5. Test Your Setup

• Trigger a build of your Jenkins job.
• Check your SNS topic to see if the notification was sent. If you subscribed an email address to the topic, you should receive an email.

Important Notes:

• Security: Protect your AWS credentials! Avoid hardcoding them in your Jenkins jobs. Use Jenkins credentials management or environment variables.
• Customization: You can customize the notification subject and message to include relevant information from your build.
• Error Handling: Implement error handling in your Jenkins job to gracefully handle situations where SNS notifications fail.
• Alternatives: Consider using the Jenkins Notification Plugin for more notification options (Slack, Microsoft Teams, etc.).
