How to send alerts to Microsoft Teams from Jenkins using Jenkinsfile

Creating webhooks from the Jenkins GUI is straightforward. So that’s why here I will explain how to create a webhook as a code to send alerts to a Teams channel. Let’s see the solution.

Prerequisites

• Jenkins installed
• sudo privileges

Solution

• Install the Office 365 Connector in your Jenkins instance. You can do this by navigating to “Manage Jenkins” > “Manage Plugins” > “Available” tab and searching for the plugin.

• Generate a webhook URL for your Microsoft Teams channel. To do this, navigate to your Teams channel, click on the three dots on the top right corner and select Connectors. Then search for Incoming Webhook and follow the prompts to set it up.

• Add the following code snippet to your Jenkinsfile.

  pipeline {
   agent any
  
   stages {
      stage('Build') {
         steps {
            // your build steps here
         }
      }
   }
     
   post {
    always {
      script{
        status = currentBuild.currentResult.toString().toLowerCase()
        color = status == 'success' ? '00ff00' : 'ff0000'
        message = "The ${env.JOB_NAME} build ${status} with #${env.BUILD_NUMBER}"
        url = "Webhook URL"
  
        office365ConnectorSend message: message, color: color, webhookUrl: url
       }
     } 
   }
  }
  

• Replace Webhook URL with the webhook URL you generated. Save and run your Jenkinsfile. This code sends a message to your Teams channel after every build, indicating the status of the build and the name of the job.
