Question 1

How does deploy-rs compare to NixOps?

Accepted Answer

deploy-rs focuses on multi-profile deployments per user with safety features like magic rollback, while NixOps is more traditional for system-wide NixOS deployments. deploy-rs offers finer granularity but requires Nix flakes.

Question 2

Can deploy-rs deploy Docker containers?

Accepted Answer

Indirectly; you can deploy Nix derivations that package Docker containers, but deploy-rs is designed for Nix-based deployments and doesn't natively manage container orchestration like Kubernetes.

Question 3

How to set up magic rollback in deploy-rs?

Accepted Answer

Magic rollback is enabled by default in configurations; ensure it's not disabled via CLI flags or settings. It automatically rolls back if SSH connectivity is lost after profile activation, as per the README.

Question 4

What are the system requirements for deploy-rs?

Accepted Answer

Requires Nix and Nix flakes support on both deployer and target nodes, along with SSH access and sudo privileges. The README notes compatibility with flake-less fallback for older Nix versions.

Question 5

How to troubleshoot failed profile activation in deploy-rs?

Accepted Answer

Check activation logs on the target node, verify SSH and sudo configurations, and use deployChecks to validate your Nix expressions before deployment, as suggested in the API section.

Question 6

Is deploy-rs suitable for continuous integration pipelines?

Accepted Answer

Yes, it can be integrated into CI/CD for automated deployments, but requires setting up Nix environments and managing SSH keys securely, with options for remote build and rollback control.
