Update SELinux AMI

[okankoAMZ]

Description of the issue

The EC2 SELinux test matrix previously used hardcoded AMI patterns such as CloudwatchSelinuxAL2v4* and CloudwatchSelinuxAL2023*. These patterns were not aligned with the standardized, dynamically selected AMI naming conventions for cloudwatch-agent integration testing. As a result, tests might not have targeted the correct or most recent AMIs, potentially impacting test coverage and reliability.

Description of changes

• Updated the "ami" field for both the Amazon Linux 2 and AL2023 test matrices to use the new, dynamic AMI name patterns:
  • Changed CloudwatchSelinuxAL2v4* to cloudwatch-agent-integration-test-selinux*
  • Changed CloudwatchSelinuxAL2023* to cloudwatch-agent-integration-test-x86-selinux*
• These updates ensure that integration tests always use the latest, dynamically selected AMIs for SELinux testing, improving test reliability and alignment with current resources.

Can you post a passing test run

The new names e.g. cloudwatch-agent-integration-test-al2-selinux might be picked up by the AMI expression we use for non-selinux tests: https://github.com/aws/amazon-cloudwatch-agent-test/blob/main/generator/resources/ec2_linux_test_matrix.json#L73C13-L73C49
