Requirements

This module requires the following:

• Windows PowerShell 4.x and above or
• PowerShell Core 6.x on:
  • Windows
  • Linux
  • macOS

Installation

If Windows Management Framework 5.0 or above is installed or the PowerShell Package management module is available:

The easiest way to download and install the Jenkins module is using PowerShell Get to download it from the PowerShell Gallery:

Install-Module -Name Jenkins

If Windows Management Framework 5.0 or above is not available and the PowerShell Package management module is not available:

Unzip the file containing this Module to your c:\Program Files\WindowsPowerShell\Modules folder.

Compatibility and Testing

This PowerShell module is automatically tested and validated to run on the following systems:

• Windows Server 2016 (using Windows PowerShell 5.1)
• Windows Server 2019 (using Windows PowerShell 5.1)
• Ubuntu 16.04 (using PowerShell Core 6)
• Ubuntu 16.04 (using PowerShell Core 7.x)
• Ubuntu 18.04 (using PowerShell Core 7.x)
• macOS 10.14 (using PowerShell Core 6)

This module should function correctly on other systems and configurations but is not automatically tested with them in every change.

Automated Integration Tests

This project contains automated integration tests that use Docker to run a Jenkins master server in a Docker Linux container. These tests can run on Windows 10 with Docker for Windows 2.0.4 or above installed. The tests also run automatically in Travis CI in the Linux build.

Cross Site Request Forgery (CSRF) Support

If a Jenkins Server has the CSRF setting enabled, then a "Crumb" will first need to be obtained and passed to each subsequent call to Jenkins in the Crumb parameter. If you receive errors regarding crumbs then your Jenkins Server has CSRF enabled and you will to ensure you are passing a valid "Crumb" obtained by calling the Get-JenkinsCrumb cmdlet.

To work with a Jenkins Master that has CSRF enabled:

$Crumb = Get-JenkinsCrumb `
    -Uri 'https://jenkins.contoso.com' `
    -Credential $Credential

New-JenkinsFolder `
    -Uri 'https://jenkins.contoso.com' `
    -Credential $Credential `
    -Crumb $Crumb `
    -Name 'Management' `
    -Verbose

Recommendations

• If your Jenkins Server has security enabled then you should ensure that you are only connecting to it via HTTPS.
• If your Jenkins Server has security enabled, the Credentials parameter that can accept either the password for the Jenkins account or the API Token. It is strongly recommended that you use the API Token for the account as the password rather than the Jenkins account, even if you have implemented HTTPS.
