cradle-deploy is a specialized command-line tool associated with the Cradle application deployment framework, primarily used in custom DevOps environments or proprietary software ecosystems. It facilitates the deployment of containerized or packaged applications to "Cradle" targets, which could be cloud instances, edge devices, or clustered servers managed by Cradle's orchestration layer.

The tool streamlines CI/CD pipelines by handling artifact uploads, configuration injection, service restarts, and rollback procedures. It supports scripting for automation and integrates with tools like Git, Docker, and systemd. Users typically invoke it from build servers or local machines with appropriate credentials.

Key features include dry-run modes for testing, parallel deployments across nodes, health checks post-deployment, and logging to stdout/stderr or files. It's lightweight, written in Go or Bash, and distributed via package managers in supported distros or as a standalone binary.

While not part of core Linux distributions (no man page in standard repos), it's documented in project-specific READMEs or wikis. Common use cases: microservices rollout, IoT firmware updates, and staging-to-production promotions. Security relies on SSH keys, tokens, or API auth.

Requires Cradle agent on targets; network access essential. Not idempotent by default; test in staging. Binary may vary by project version.
