Using AWS Systems Manager to automatically install or update Amazon EFS client - Amazon Elastic File System

Using AWS Systems Manager to automatically install or update Amazon EFS client

You can use AWS Systems Manager to simplify the management of the Amazon EFS client (amazon-efs-utils). AWS Systems Manager is an AWS service that you can use to view and control your infrastructure on AWS. With AWS Systems Manager you can automate the tasks required to install or update the amazon-efs-utils package on your EC2 instances. The Systems Manager capabilities like Distributor and State Manager enable you to automate the following processes:

  • Maintaining version control over the Amazon EFS client.

  • Centrally storing and systematically distributing the Amazon EFS client to your Amazon EC2 instances.

  • Automate the process of keeping your Amazon EC2 instances in a defined state.

For more information, see the AWS Systems Manager User Guide.

What the Amazon EFS client does during installation

You use the Amazon EFS client to automate monitoring Amazon CloudWatch logs for file system mount status and upgrade stunnel to the latest version for selected Linux distributions. When you install the Amazon EFS client on your Amazon EC2 instances using Systems Manager, it takes the following actions:

  • Installs the botocore package using the same steps described in Installing and upgrading botocore. The Amazon EFS client uses botocore to monitor the EFS file system mount status.

  • Enables the monitoring of EFS file system mount status in CloudWatch logs by updating efs-utils.conf. For more information, see Monitoring mount attempt successes and failures.

  • For EC2 instances running RHEL7 or CentOS7, the Amazon EFS client automatically upgrades stunnel as described in Upgrading stunnel. Upgrading stunnel is required in order to successfully mount an EFS file system using TLS, and the stunnel version shipped with RHEL7 and CentOS7 does not support the Amazon EFS client (amazon-efs-utils).

Systems Manager Distributor supported operating systems

Your EC2 instances must be running one of the following operating systems in order to be used with AWS Systems Manager to automatically update or install the Amazon EFS client.
