Deployment failures can significantly disrupt your workflow and impact your users. The Deployments tab in AWS Elastic Beanstalk exists to alleviate this pain by providing a consolidated view of your deployment history and real-time logs. This feature allows you to quickly identify what went wrong during a deployment, making it easier to troubleshoot and fix issues before they escalate.

During a deployment, one instance uploads its log to Amazon S3 as the process progresses. The Elastic Beanstalk console reads from S3, allowing you to monitor the deployment in real time. This means you don’t have to connect to the instance to see what's happening. Once the deployment completes, the console fetches the final log to ensure you have the complete output. Key parameters like EnvironmentType and IamInstanceProfile help configure your environment correctly, with defaults set to SingleInstance and aws-elasticbeanstalk-ec2-role, respectively.

In production, you need to ensure that your AWS account has the necessary permissions to create Elastic Beanstalk environments and associated resources. Be mindful that deployment logs are only available on specific platform versions released after March 11, 2026. If you encounter issues, remember that the default instance profile may not be created automatically in new AWS accounts, which can lead to failed launches. Always check your environment settings and logs for insights into deployment failures.

Key takeaways

→Utilize the Deployments tab for a consolidated view of deployment history.
→Monitor real-time deployment logs uploaded to S3 to diagnose issues quickly.
→Ensure your AWS account has the necessary permissions for Elastic Beanstalk resources.
→Check platform version compatibility for deployment logs availability.
→Be aware of the default instance profile requirements in new AWS accounts.

Why it matters

In production, rapid identification and resolution of deployment failures can minimize downtime and enhance user experience. The Deployments tab provides critical insights that can save hours of troubleshooting.
