# Zinit RPC Client
|
||||
|
||||
This is a V language client for the Zinit process manager, implementing the JSON-RPC API specification for service management operations.
|
||||
|
||||
## Overview
|
||||
|
||||
Zinit is a process manager that provides service monitoring, dependency management, and system control capabilities. This client provides a comprehensive API to interact with Zinit via its JSON-RPC interface for administrative tasks such as:
|
||||
|
||||
- Service lifecycle management (start, stop, monitor, forget)
|
||||
- Service configuration management (create, delete, get)
|
||||
- Service status and statistics monitoring
|
||||
- System operations (shutdown, reboot, HTTP server control)
|
||||
- Log streaming and monitoring
|
||||
|
||||
## Features
|
||||
|
||||
- **✅ 100% API Coverage**: Complete implementation of all 18 methods in the Zinit JSON-RPC specification
|
||||
- **✅ Production Tested**: All methods tested and working against real Zinit instances
|
||||
- **✅ Type-safe API**: Proper V struct definitions with comprehensive error handling
|
||||
- **✅ Subscription Support**: Proper handling of streaming/subscription methods
|
||||
- **✅ Unix Socket Transport**: Reliable communication via Unix domain sockets
|
||||
- **✅ Comprehensive Documentation**: Extensive documentation with working examples
|
||||
|
||||
## Usage
|
||||
|
||||
### Basic Example
|
||||
|
||||
```v
|
||||
import freeflowuniverse.herolib.clients.zinit_rpc
|
||||
|
||||
// Create a new client
|
||||
mut client := zinit_rpc.new_client(
|
||||
name: 'my_client'
|
||||
socket_path: '/tmp/zinit.sock'
|
||||
)!
|
||||
|
||||
// List all services
|
||||
services := client.service_list()!
|
||||
for service_name, state in services {
|
||||
println('Service: ${service_name}, State: ${state}')
|
||||
}
|
||||
|
||||
// Get detailed status of a specific service
|
||||
status := client.service_status('redis')!
|
||||
println('Service: ${status.name}')
|
||||
println('PID: ${status.pid}')
|
||||
println('State: ${status.state}')
|
||||
println('Target: ${status.target}')
|
||||
|
||||
// Start a service
|
||||
client.service_start('redis')!
|
||||
|
||||
// Stop a service
|
||||
client.service_stop('redis')!
|
||||
```
|
||||
|
||||
### Service Configuration Management
|
||||
|
||||
```v
|
||||
import freeflowuniverse.herolib.clients.zinit_rpc
|
||||
|
||||
mut client := zinit_rpc.new_client()!
|
||||
|
||||
// Create a new service configuration
|
||||
config := zinit_rpc.ServiceConfig{
|
||||
exec: '/usr/bin/redis-server'
|
||||
oneshot: false
|
||||
log: 'stdout'
|
||||
env: {
|
||||
'REDIS_PORT': '6379'
|
||||
'REDIS_HOST': '0.0.0.0'
|
||||
}
|
||||
shutdown_timeout: 30
|
||||
}
|
||||
|
||||
// Create the service
|
||||
path := client.service_create('redis', config)!
|
||||
println('Service created at: ${path}')
|
||||
|
||||
// Get service configuration
|
||||
retrieved_config := client.service_get('redis')!
|
||||
println('Service exec: ${retrieved_config.exec}')
|
||||
|
||||
// Delete service configuration
|
||||
result := client.service_delete('redis')!
|
||||
println('Delete result: ${result}')
|
||||
```
|
||||
|
||||
### Service Statistics
|
||||
|
||||
```v
|
||||
import freeflowuniverse.herolib.clients.zinit_rpc
|
||||
|
||||
mut client := zinit_rpc.new_client()!
|
||||
|
||||
// Get service statistics
|
||||
stats := client.service_stats('redis')!
|
||||
println('Service: ${stats.name}')
|
||||
println('PID: ${stats.pid}')
|
||||
println('Memory Usage: ${stats.memory_usage} bytes')
|
||||
println('CPU Usage: ${stats.cpu_usage}%')
|
||||
|
||||
// Print child process statistics
|
||||
for child in stats.children {
|
||||
println('Child PID: ${child.pid}, Memory: ${child.memory_usage}, CPU: ${child.cpu_usage}%')
|
||||
}
|
||||
```
|
||||
|
||||
### Log Streaming
|
||||
|
||||
```v
|
||||
import freeflowuniverse.herolib.clients.zinit_rpc
|
||||
|
||||
mut client := zinit_rpc.new_client()!
|
||||
|
||||
// Get current logs for all services
|
||||
logs := client.stream_current_logs(name: '')!
|
||||
for log in logs {
|
||||
println(log)
|
||||
}
|
||||
|
||||
// Get current logs for a specific service
|
||||
redis_logs := client.stream_current_logs(name: 'redis')!
|
||||
for log in redis_logs {
|
||||
println('Redis: ${log}')
|
||||
}
|
||||
|
||||
// Subscribe to log stream (returns subscription ID)
|
||||
subscription_id := client.stream_subscribe_logs(name: 'redis')!
|
||||
println('Subscribed to logs with ID: ${subscription_id}')
|
||||
```

||||

||||

```
|
||||
|
||||
### Example Heroscript Configuration
|
||||
|
||||
```hero
|
||||
!!zinit_rpc.configure
|
||||
name: 'production'
|
||||
socket_path: '/tmp/zinit.sock'
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
The client provides comprehensive error handling for all Zinit-specific error codes:
|
||||
|
||||
- `-32000`: Service not found
|
||||
- `-32001`: Service already monitored
|
||||
- `-32002`: Service is up
|
||||
- `-32003`: Service is down
|
||||
- `-32004`: Invalid signal
|
||||
- `-32005`: Config error
|
||||
- `-32006`: Shutting down
|
||||
- `-32007`: Service already exists
|
||||
- `-32008`: Service file error
|
||||
|
||||
```v
|
||||
import freeflowuniverse.herolib.clients.zinit_rpc
|
||||
|
||||
mut client := zinit_rpc.new_client()!
|
||||
|
||||
// Handle specific errors
|
||||
client.service_start('nonexistent') or {
|
||||
if err.msg().contains('Service not found') {
|
||||
println('Service does not exist')
|
||||
} else {
|
||||
println('Other error: ${err}')
|
||||
}
|
||||
}
|
||||
```
