You can use the custom runtime of Function Compute to write functions in PowerShell. This topic describes how to deploy and invoke a PowerShell function.

Prerequisites

Node.js 8.6.0 or later is installed. For more information, visit Downloads.

Step 1: Prepare the environment

The easiest way to install Funcraft is to download the executable binary files.

  1. Install Funcraft on an on-premises machine. For more information, see Install Funcraft.
  2. Run the fun --version command to check whether the installation is successful.
  3. Run the fun config command to configure Funcraft. Set the Account ID, Access Key ID, Access Key Secret, and Default region name parameters as prompted.
    fun config
    Aliyun Account ID 1234xxx
    Aliyun Access Key ID xxxx
    Aliyun Access Key Secret xxxx
    Default region name cn-xxxx
    The timeout in seconds for each SDK client invoking 300
    The maximum number of retries for each SDK client 5
    Allow to anonynously report usage statistics to improve the tool over time? (Y/n)

Step 2: Deploy and invoke a function

  1. Run the following command to clone the sample project to the on-premises machine:
    git clone https://github.com/awesome-fc/fc-custom-demo          
    Note If you do not install Git, you can download the sample project from https://github.com/awesome-fc/fc-custom-demo.
  2. Run the following commands to go to the cloned sample project:
    1. Run the following command to go to the fc-custom-demo directory:
      cd fc-custom-demo
    2. Run the following command to go to the powershell-demo directory:
      cd powershell-demo       
  3. Run the following command to deploy the project to Function Compute:
    fun deploy -y      
    The following result is returned:
    Waiting for service powershell-demo to be deployed...
            Waiting for function fc-powershell to be deployed...
                    Waiting for packaging function fc-powershell code...
                    The function fc-powershell has been packaged. A total of 2 files were compressed and the final size was 882 B
            function fc-powershell deploy success
    service powershell-demo deploy success
  4. Run the following command to invoke the deployed function:
    fun invoke -e "Hello World"          
    Note If you use the Windows operating system, you must convert the format of the bootstrap file to UNIX.
    The following result is returned:
    ========= FC invoke Logs begin =========
    FC Invoke Start RequestId: cd30369e-7dfa-439c-a68d-7fe16d5a7e05
    Hello World
    FC Invoke End RequestId: cd30369e-7dfa-439c-a68d-7fe16d5a7e05
    
    Duration: 54.13 ms, Billed Duration: 100 ms, Memory Size: 512 MB, Max Memory Used: 133.70 MB
    ========= FC invoke Logs end =========
    
    FC Invoke Result:
    Hello World
