CodeDeploy Agent 2.0.0 Preview

---

Hello all,

We are releasing a new version of the CodeDeploy Agent written in Rust, completely removing the Ruby dependency. There is a preview available under the v2-experimental branch. We'd love for you to try it out and tell us what you find.

What is changing and what is not:

• No Ruby runtime. v2 is a single self-contained native binary — no interpreter, no gems, one portable artifact across OS/distributions.
• Extended support for the latest OS versions such as RHEL 10, Ubuntu Server 26.04 LTS, and Windows Microsoft Server 2025.
• Backward compatible by design. Deployment outcomes, AppSpec handling, hook semantics, and on-disk layout all match the Ruby agent. Your existing config files stay unchanged.

How you can help — this is experimental, so please keep it off production for now. On test/staging instances:

1. Clone and build from v2-experimental branch and point it at a non-prod deployment group.
2. Run your real deployments, your actual AppSpecs, hooks, permissions, runas/sudo, EC2 or on-prem.
3. File GitHub issues with your OS/arch and config (secrets redacted), especially:
   - anything that behaves differently from the Ruby agent,
   - install/upgrade/packaging issues on your distro,
   - hooks relying on env vars beyond the documented deployment vars.

If you notice gaps, open an issue or comment to this thread.

Thanks for helping us get the transition right.
