32-haskell-nonempty-waves

This example shows intermediate Haskell rollout planning with NonEmpty.

It includes:

• a deployment job with rolling and canary modes,
• a NonEmpty list of rollout waves that guarantees at least one step,
• a CLI that renders a wave-by-wave plan, and
• a test suite run by nix flake check.

Useful commands:

nix develop
cabal run
cabal run -- api:production:canary:20:6
cabal test

nix build
./result/bin/mini-waves api:production:canary:20:6

nix run . -- api:production:canary:20:6
nix flake check
