Main Features

🎯 Fluent Configuration API: Chain methods to build supervisord config ⚡ Kratos Integration: Optimized configuration patterns to run Kratos microservices 🔄 Group Management: Multi-program groups with centralized configuration 🌍 Tested Configuration: Battle-tested templates that run high-performance services 📋 Strong Typing: Typed configuration with sensible defaults

Installation

go get github.com/yylego/kratos-supervisordrun/supervisordrunkratos

Usage

Single Program Configuration

package main

import (
    "fmt"
    "github.com/yylego/kratos-supervisordrun/supervisordrunkratos"
)

func main() {
    // Create program config with required parameters
    program := supervisordrunkratos.NewProgramConfig(
        "myapp",           // Program name
        "/opt/myapp",      // Program root DIR
        "deploy",          // User name
        "/var/log/myapp",  // Log DIR
    ).WithStartRetries(10).
      WithEnvironment(map[string]string{
          "APP_ENV": "production",
      })

    // Generate configuration
    config := supervisordrunkratos.GenerateProgramConfig(program)
    fmt.Println(config)
}

Group Configuration

// Create multiple programs
apiServer := supervisordrunkratos.NewProgramConfig(
    "api-server", "/opt/api-server", "deploy", "/var/log/services",
).WithStartRetries(3)

worker := supervisordrunkratos.NewProgramConfig(
    "worker", "/opt/worker", "deploy", "/var/log/services",
).WithAutoStart(false)

// Create group
group := supervisordrunkratos.NewGroupConfig("microservices").
    AddProgram(apiServer).
    AddProgram(worker)

config := supervisordrunkratos.GenerateGroupConfig(group)

Advanced Configuration

// High-performance service configuration
program := supervisordrunkratos.NewProgramConfig(
    "high-perf", "/opt/high-perf", "performance", "/var/log/perf",
).WithStartRetries(100).
  WithStopWaitSecs(60).
  WithLogMaxBytes("500MB").
  WithLogBackups(50).
  WithPriority(1)

Multi-Instance Deployment

// Multi-instance web server
program := supervisordrunkratos.NewProgramConfig(
    "web-server", "/opt/web-server", "deploy", "/var/log/cluster",
).WithNumProcs(3).
  WithProcessName("%(program_name)s_%(process_num)02d").
  WithEnvironment(map[string]string{
      "PORT_BASE": "8080",
  })

Configuration Options

Process Settings

• WithAutoStart(bool) - Auto start on supervisord startup
• WithAutoRestart(bool) - Auto restart on crash
• WithAutoRestartMode(string) - Auto restart mode ("false"/"true"/"unexpected")
• WithStartRetries(int) - Max start attempts count
• WithStartSecs(int) - Wait time in seconds before start succeeds

Logging

• WithLogMaxBytes(string) - Max log file size (e.g., "50MB", "1GB")
• WithLogBackups(int) - Log backup files count
• WithRedirectStderr(bool) - Redirect stderr to stdout

Process Execution

• WithStopWaitSecs(int) - Clean stop timeout seconds
• WithStopSignal(string) - Stop command name (TERM, INT, QUIT)
• WithKillAsGroup(bool) - Terminate child processes as group
• WithPriority(int) - Start rank (low ranks start first)

Multi-Instance

• WithNumProcs(int) - Count of process instances
• WithProcessName(string) - Process name template

Environment

• WithEnvironment(map[string]string) - Environment setting
• WithExitCodes([]int) - Expected exit codes

Recommended Workflow

# 1. Generate config file
go run main.go > /etc/supervisord/conf.d/myapp.conf

# 2. Reload supervisord
sudo supervisorctl reread
sudo supervisorctl update

# 3. Manage services
sudo supervisorctl start myapp
sudo supervisorctl status
