Zinit is a lightweight PID 1 replacement inspired by runit, written in Rust using Tokio for async I/O. It provides both a Unix socket interface and an HTTP API for interacting with the process manager.
- Service Management: Ensures configured services are up and running at all times
- Dependency Handling: Supports service dependencies for proper startup ordering
- Simple Control Interface: Provides an intuitive CLI to add, start, stop, and monitor services
- Container Support: Can run in container mode with appropriate signal handling
- Configurable Logging: Multiple logging options including ringbuffer and stdout

# Run zinit in init mode
zinit init --config /etc/zinit/ --socket /var/run/zinit.sock
# List services
zinit list
# Start a service
zinit start <service-name>
# Stop a service
zinit stop <service-name># Start the HTTP proxy on the default port (8080)

Zinit uses YAML files for service configuration. Here's a basic example:
# Service configuration (e.g., /etc/zinit/myservice.yaml)
exec: "/usr/bin/myservice --option value" # Command to run (required)
test: "/usr/bin/check-myservice" # Health check command (optional)
oneshot: false # Whether to restart on exit (default: false)
after: # Services that must be running first (optional)

The HTTP proxy provides a JSON-RPC 2.0 API for interacting with Zinit. You can send JSON-RPC requests to the HTTP endpoint you provided to the proxy:
curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"service_list","params":{}}' http://localhost:8080/See the OpenRPC specs for more information about available RPC calls to interact with Zinit.
