Deploying Stuff from Win Machine To Linux via PowerShell

Introduction

When I was copying files or binaries from my Win machine into Raspberry or Azure VM, I was using WinSCP every time. It is ok when I have to do it once after a build. But when I have to copy it ten times in one hour,  because I am fixing a problem, it is annoying.

So I decided to automate it. It is possible to use WinSCP from command line. But there is a better option – PowerShell Module POSH-SSH, which contains CmdLets for conneting via SSH, SCP or SFTP.

 

Example – A Script to Copy Files on Linux Machine and Switch with Previous Version

# install latest version of the module
iex (New-Object Net.WebClient).DownloadString("https://gist.github.com/darkoperator/6152630/raw/c67de4f7cd780ba367cccbc2593f38d18ce6df89/instposhsshdev")

And the script itself:

$userName = "USER_NAME"
$credentials = New-Object -TypeName System.Management.Automation.PSCredential ($userName, (new-object System.Security.SecureString))
$sshKey = "SSH_KEY_PATH"
$localFolder = "LOCAL_FOLDER_PATH"
$remoteFolder = "REMOTE_FOLDER_PATH"
$computerName = "MACHINE_ADDRESS"
$port = 22
$commands = @("CMD_1", "CMD_2", "CMD_3")

Write-Host "Uploading data from $localFolder to $remoteFolder on $userName|$computerName|$port" -ForegroundColor Yellow
Set-SCPFolder -LocalFolder $localFolder -RemoteFolder $remoteFolder -ComputerName $computerName -Port $port -AcceptKey -Credential $credentials -KeyFile $sshKey
Write-Host "Done" -ForegroundColor Yellow

Write-Host "Connecting to $userName|$computerName|$port to execute commands" -ForegroundColor Yellow
$session = New-SSHSession -ComputerName $computerName -Port $port -AcceptKey -Credential $credentials -KeyFile $sshKey
ForEach ($cmd in $commands) {
Write-Host "Executing $cmd" -ForegroundColor Yellow
$result = (Invoke-SSHCommand -SSHSession $session -Command $cmd).Output
Write-Host $result.split("`n")
}

Remove-SSHSession -SSHSession $session

This code does following:

  1. It copies folder LOCAL_FOLDER_PATH into REMOTE_FOLDER_PATH on target machine via SCP (and SSH key)
  2. Next it connects via SSH (key) and executes commands CMD_1, CMD_2 and CMD_3.

 

So now, after each new build I can run this script and a new version of the project will be uploaded to the machine. Or this script can be set as a post build task into pipeline.

Meme Code Review Google Chrome Extension

Introduction

Code review can be sometimes very boring. Checking hundreds of lines can be more fun with memes in comments!
For this purpose I made a small extension into Google Chrome that enables you to insert meme in a simple way.

Current version supports this feature on GitHub and Bitbucket.

How to use it

After installation of the plugin, you have to set memes that you want to use (menu -> settings -> extensions -> Meme Code Review -> options). On this page you set name and url of the meme image (see Figure 1).

Now, you can use it -> just open GitHub (Figure 2) or Bitbucket (Figure 3). Then click on the troll button. A list of saved memes appears. If you click on the meme image, its address will be inserted into text area.

Enjoy it!
