Summary

• Amazon Linux 2 reached its AWS end-of-life on June 30, 2026, and localstack/localstack-pro#8250 removed it from the set of AMIs LocalStack downloads by default for the EC2 Docker VM manager.
• Removes the Amazon Linux 2 entry from the default AMI list in ec2.mdx and adds a note explaining that it's no longer pre-loaded, with the docker pull/docker tag steps to manually register it if still needed.
• Ubuntu 22.04 and Amazon Linux 2023 remain pre-loaded and unchanged; other unrelated "Amazon Linux 2" mentions in the repo (CodeBuild, EKS, Lambda runtimes) refer to different AMI families and were left untouched.

Audit Trail

• Sources accessed: https://aws.amazon.com/amazon-linux-2/faqs/ (AL2 EOL date); engineering PR https://github.com/localstack/localstack-pro/pull/8250 (file diff confirms AMAZONLINUX_2_AMI/AMAZONLINUX_2_DOCKER_IMAGE removed from DEFAULT_IMAGES in vmmanager/docker.py, plus the Dockerfile and CI matrix/test updates).
• Coverage files parsed: N/A — this is a Docker VMM configuration doc, not a service API coverage doc.
• Confidence & gaps: High confidence; verified against the actual code diff rather than just the PR description. No conflicting AWS/LocalStack behavior found.

Test plan

• npm run build — link/frontmatter validation passed, no broken links.
• Confirmed AL2 removal against the localstack-pro#8250 file diff (docker.py, Dockerfile removal, CI matrix, tests).

Closes DOC-405.
