Akka.Net을 이용한 환경구성 이해와 도커환경 테스트

August 09, 2022

완료조건(주요결과)

AKka.NET의 코드 이해와 이전의 RESTFUL API를 연동하여 도커화 진행하기

목차

00.프로젝트 생성

ASP.NET Core Web API 검색

옵션 선택 Enable Docker, Docker OS Linux선택

01.CliWrap 사용해보기

NuGet Package에서 CliWrap검색해서 설치진행

using CliWrap;
using System.Text;

var stdOutBuffer = new StringBuilder();
var stdErrBuffer = new StringBuilder();

var exeCommand = "PowerShell.exe";  // 실행 지정                

string computerIp = "192.168.100.116";
string pid = "60144";
string scriptBlock = $"cmd.exe /c taskkill /f /pid "+ pid;
string userName = "km.park";
string passWord = "mirero";
string script = $"-Command \" & {{Invoke-Command -ComputerName {computerIp} -ScriptBlock {{ {scriptBlock} }} -Authentication Negotiate -Credential (New-Object System.Management.Automation.PSCredential {userName}, (ConvertTo-SecureString -AsPlainText -Force {passWord}))  -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) }}\"";

Console.WriteLine($"\nscript: {script}\n");

var result = await Cli.Wrap(exeCommand)
    .WithArguments(script)
    .WithStandardOutputPipe(PipeTarget.ToStringBuilder(stdOutBuffer))
    .WithStandardErrorPipe(PipeTarget.ToStringBuilder(stdErrBuffer))  
    .ExecuteAsync();

var stdOut = stdOutBuffer.ToString();
var stdErr = stdErrBuffer.ToString();

Console.WriteLine("Info:" + stdOut);
Console.WriteLine("Error:" + stdErr);

우선위와 같이 입력을 하고 진행을 하게되면 서비스를 죽일 수 있게됨

using CliWrap;
using System.Text;

var stdOutBuffer = new StringBuilder();
var stdErrBuffer = new StringBuilder();

var exeCommand = "PowerShell.exe";  // 실행 지정                

string computerIp = "192.168.100.116";
string pid=null;
string scriptBlock;
string userName = "km.park";
string passWord = "mirero";
string serviceName = "ServiceNormal_60s Service Name";
string script = $"-Command \" & {{ cmd.exe /c sc queryex '"+ serviceName + "'}\"";

Console.WriteLine($"\nscript: {script}\n");

var result = await Cli.Wrap(exeCommand)
    .WithArguments(script)
    .WithStandardOutputPipe(PipeTarget.ToStringBuilder(stdOutBuffer))
    .WithStandardErrorPipe(PipeTarget.ToStringBuilder(stdErrBuffer))  
    .ExecuteAsync();
var stdOut = stdOutBuffer.ToString();
var stdErr = stdErrBuffer.ToString();

Console.WriteLine("Info:" + stdOut);
Console.WriteLine("Error:" + stdErr);

var index = stdOut.IndexOf("PID");
for (int i = index + 21; !stdOut[i].Equals('\n'); i++)
{
    pid += stdOut[i];
}

scriptBlock = $"cmd.exe /c taskkill /f /pid " + pid;

script = $"-Command \" & {{Invoke-Command -ComputerName {computerIp} -ScriptBlock {{ {scriptBlock} }} -Authentication Negotiate -Credential (New-Object System.Management.Automation.PSCredential {userName}, (ConvertTo-SecureString -AsPlainText -Force {passWord}))  -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) }}\"";

result = await Cli.Wrap(exeCommand)
    .WithArguments(script)
    .WithStandardOutputPipe(PipeTarget.ToStringBuilder(stdOutBuffer))
    .WithStandardErrorPipe(PipeTarget.ToStringBuilder(stdErrBuffer))
    .ExecuteAsync();
stdOut = stdOutBuffer.ToString();
stdErr = stdErrBuffer.ToString();

Console.WriteLine("Info:" + stdOut);
Console.WriteLine("Error:" + stdErr);

이름으로 ip 찾아서 죽이는 것

02.API에 기능 추가해보기

서비스 죽이는 것

app.MapPost("/programKillOrder", async (SendMessage info) =>
{
    Console.WriteLine("");
    Console.WriteLine(info);

    var stdOutBuffer = new StringBuilder();
    var stdErrBuffer = new StringBuilder();

    var exeCommand = "Powershell.exe";  // 실행 지정                

    string computerIp = info.Ip;
    string pid = null;
    string scriptBlock;
    string userName = info.Username;
    string passWord = info.Password;
    string serviceName = info.ServiceName;
    string script = $"-Command \" & {{ cmd.exe /c sc queryex '" + serviceName + "'}\"";

    Console.WriteLine($"\nscript: {script}\n");

    var result = await Cli.Wrap(exeCommand)
        .WithArguments(script)
        .WithStandardOutputPipe(PipeTarget.ToStringBuilder(stdOutBuffer))
        .WithStandardErrorPipe(PipeTarget.ToStringBuilder(stdErrBuffer))
        .ExecuteAsync();
    var stdOut = stdOutBuffer.ToString();
    var stdErr = stdErrBuffer.ToString();

    Console.WriteLine("Info:" + stdOut);
    Console.WriteLine("Error:" + stdErr);

    var index = stdOut.IndexOf("PID");
    for (int i = index + 21; !stdOut[i].Equals('\n'); i++) pid += stdOut[i];

    scriptBlock = $"cmd.exe /c taskkill /f /pid " + pid;

    script = $"-Command \" & {{Invoke-Command -ComputerName {computerIp} -ScriptBlock {{ {scriptBlock} }} -Authentication Negotiate -Credential (New-Object System.Management.Automation.PSCredential {userName}, (ConvertTo-SecureString -AsPlainText -Force {passWord}))  -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) }}\"";

    result = await Cli.Wrap(exeCommand)
        .WithArguments(script)
        .WithStandardOutputPipe(PipeTarget.ToStringBuilder(stdOutBuffer))
        .WithStandardErrorPipe(PipeTarget.ToStringBuilder(stdErrBuffer))
        .ExecuteAsync();
    stdOut = stdOutBuffer.ToString();
    stdErr = stdErrBuffer.ToString();

    Console.WriteLine("Info:" + stdOut);
    Console.WriteLine("Error:" + stdErr);

    return info;

})
.WithName("programKillOrder");

json 보내는 형식

{
  "ip": "192.168.100.116",
  "password": "mirero",
  "username": "km.park",
  "serviceName": "ServiceNormal_60s Service Name"
}

일단 문제는 docker에서 실행하면 안됨 이유는 powershell이 설치 안되어있기때문에 이를 하기 위해 powershell이랑 원격제어를 위한 ntlm..을 설치해야함

03.Powershell, gss-ntlmssp 추가 하기

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.
