Some Recovery Kits use AWS Instance Metadata Service (IMDS) to retrieve instance metadata. You can use AWS IMDS version 1 or 2. However, if you change the configuration on AWS, you may also need to change the configuration on LifeKeeper.

Configuring Amazon EC2 IMDS

Refer to the AWS document below:
Modify instance metadata options for existing instances

Configuring LifeKeeper for Linux

Set the value following the table below according to the version of IMDS to be used in /etc/default/LifeKeeper. For details on the parameters, refer to the EC2 Parameter List.

/etc/default/LifeKeeper Note
AWS_IMDS_VERSION=1 Retrieve instance metadata using IMDSv1. (*1)
AWS_IMDS_VERSION=2 Retrieve instance metadata using IMDSv2.

*1 Errors will occur if IMDSv2 is configured in Amazon EC2 IMDS settings as “required”.
