A small Rust command-line utility that blocks until other Docker containers (or services in Kubernetes/docker stack) are ready, by waiting for a fixed time, open TCP ports, or files on the filesystem. It is typically added to a Dockerfile and run before the application's entrypoint to ensure dependencies like databases are available.

Use cases

• wait for postgres and mysql to be ready before starting my app in docker-compose
• delay container startup until a tcp port is open
• make my app wait for mongodb in a docker stack deployment
• synchronize service startup order in kubernetes without healthcheck hacks
• wait for a file to exist before launching my application container
• use a wait tool in distroless or scratch docker images

When to choose

• you use docker-compose, docker stack, or Kubernetes and need simple dependency readiness gating
• you want a tiny static binary that works in scratch or distroless images
• you need to wait on TCP ports or filesystem paths via environment variables

When to avoid

• your orchestrator already supports healthchecks with depends_on conditions or init containers
• you need complex readiness logic beyond ports, files, or timeouts
