Step 1: Review Your Packages

Step 2: Choose Your Integration Method

Step 3: Copy Your Script or Download Config

Option 1: Copy Script

Option 2: Download Config

Step 4: Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

Option 1: Cached Package (Unreliable, Requires Internet - Same As Community)

Open Source or Commercial:
- Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
- You can also just download the packages and push them to a repository
  Download Packages

Option 2: Internalized Package (Reliable, Scalable)

Open Source
- Download the packages:
  Download Packages
- Follow manual internalization instructions
Package Internalizer (C4B)
- Run: (additional options)
- For package and dependencies run:
- Automate package internalization

Step 5: Copy Your Script

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

If Applicable - Chocolatey Configuration/Installation


## 1. REQUIREMENTS ##
### Here are the requirements necessary to ensure this is successful.

### a. Internal/Private Cloud Repository Set Up ###
#### You'll need an internal/private cloud repository you can use. These are
####  generally really quick to set up and there are quite a few options.
####  Chocolatey Software recommends Nexus, Artifactory Pro, or ProGet as they
####  are repository servers and will give you the ability to manage multiple
####  repositories and types from one server installation.

### b. Download Chocolatey Package and Put on Internal Repository ###
#### You need to have downloaded the Chocolatey package as well.
####  Please see https://chocolatey.org/install#organization

### c. Other Requirements ###

#### We initialize a few things that are needed by this script - there are no other requirements.
$ErrorActionPreference = "Stop"

#### Set TLS 1.2 (3072) as that is the minimum required by various up-to-date repositories.
#### Use integers because the enumeration value for TLS 1.2 won't exist
#### in .NET 4.0, even though they are addressable if .NET 4.5+ is
#### installed (.NET 4.5 is an in-place upgrade).
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072

#### We use this variable for future REST calls.
$RequestArguments = @{
    UseBasicParsing = $true
}

## 2. TOP LEVEL VARIABLES ##

### a. Your internal repository url (the main one). ###
####  Should be similar to what you see when you browse
#### to https://community.chocolatey.org/api/v2/
$NugetRepositoryUrl = "INTERNAL REPO URL"

### b. Internal Repository Credential ###
#### If required, add the repository access credential here
# $NugetRepositoryCredential = [PSCredential]::new(
#     "username",
#     ("password" | ConvertTo-SecureString -AsPlainText -Force)
# )
# $RequestArguments.Credential = $NugetRepositoryCredential

### c. Chocolatey nupkg download url ###
#### This url should result in an immediate download when you navigate to it
$ChocolateyDownloadUrl = "$($NugetRepositoryUrl.TrimEnd('/'))/package/chocolatey.2.2.2.nupkg"

### d. Chocolatey Central Management (CCM) ###
#### If using CCM to manage Chocolatey, add the following:
#### i. Endpoint URL for CCM
# $ChocolateyCentralManagementUrl = "https://chocolatey-central-management:24020/ChocolateyManagementService"

#### ii. If using a Client Salt, add it here
# $ChocolateyCentralManagementClientSalt = "clientsalt"

#### iii. If using a Service Salt, add it here
# $ChocolateyCentralManagementServiceSalt = "servicesalt"

## 3. ENSURE CHOCOLATEY IS INSTALLED ##
### Ensure Chocolatey is installed from your internal repository

#### Download the Nupkg, appending .zip to the filename to handle archive cmdlet limitations
if (-not (Get-Command choco.exe -ErrorAction SilentlyContinue)) {
    $TempDirectory = Join-Path $env:Temp "chocolateyInstall"
    if (-not (Test-Path $TempDirectory -PathType Container)) {
        $null = New-Item -Path $TempDirectory -ItemType Directory
    }
    $DownloadedNupkg = Join-Path $TempDirectory "$(Split-Path $ChocolateyDownloadUrl -Leaf).zip"
    Invoke-WebRequest -Uri $ChocolateyDownloadUrl -OutFile $DownloadedNupkg @RequestArguments

    #### Extract the Nupkg, and run the chocolateyInstall script
    if (Get-Command Microsoft.PowerShell.Archive\Expand-Archive -ErrorAction SilentlyContinue) {
        Microsoft.PowerShell.Archive\Expand-Archive -Path $DownloadedNupkg -DestinationPath $TempDirectory -Force
    } else {
        # PowerShell versions <4.0 do not have this function available
        try {
            $shellApplication = New-Object -ComObject Shell.Application
            $zipPackage = $shellApplication.NameSpace($DownloadedNupkg)
            $destinationFolder = $shellApplication.NameSpace($TempDirectory)
            $destinationFolder.CopyHere($zipPackage.Items(), 0x10)
        } catch {
            Write-Warning "Unable to unzip package using built-in compression."
            throw $_
        }
    }

    & $(Join-Path $TempDirectory "tools\chocolateyInstall.ps1")
}

if (-not (Get-Command choco.exe -ErrorAction SilentlyContinue)) {
    refreshenv
}

## 4. CONFIGURE CHOCOLATEY BASELINE ##
### a. FIPS Feature ###
#### If you need FIPS compliance - make this the first thing you configure
#### before you do any additional configuration or package installations
# choco feature enable -n useFipsCompliantChecksums

### b. Apply Recommended Configuration ###
#### Move cache location so Chocolatey is very deterministic about
#### cleaning up temporary data and the location is secured to admins
choco config set --name cacheLocation --value C:\ProgramData\chocolatey\cache

#### Increase timeout to at least 4 hours
choco config set --name commandExecutionTimeoutSeconds --value 14400

#### Turn off download progress when running choco through integrations
choco feature disable --name showDownloadProgress

### c. Sources ###
#### Remove the default community package repository source
choco source list --limitoutput | ConvertFrom-Csv -Header 'Name', 'Location' -Delimiter '|' | ForEach-Object {
    if ($_.Location -eq 'https://community.chocolatey.org/api/v2/') {
        choco source remove -n $_.Name
    }
}

#### Add internal default sources
#### You could have multiple sources here, so we will provide an example
#### of one using the remote repo variable here

#### NOTE: This EXAMPLE may require changes
if ($NugetRepositoryCredential) {
    choco source add --name ChocolateyInternal --source $NugetRepositoryUrl --user $NugetRepositoryCredential.UserName --password $NugetRepositoryCredential.GetNetworkCredential().Password --priority 1
} else {
    choco source add --name ChocolateyInternal --source $NugetRepositoryUrl --priority 1
}

### b. Keep Chocolatey Up To Date ###
#### Keep chocolatey up to date based on your internal source
#### You control the upgrades based on when you push an updated version
####  to your internal repository.
#### Note the source here is to the OData feed, similar to what you see
####  when you browse to https://community.chocolatey.org/api/v2/
choco upgrade chocolatey --confirm

## 5. ENSURE CHOCOLATEY FOR BUSINESS ##
### If you don't have Chocolatey for Business (C4B), you'll want to remove from here down.

### a. Ensure The License File Is Installed ###
#### Create a license package using script from https://docs.chocolatey.org/en-us/how-tos/setup-offline-installation#exercise-4-create-a-package-for-the-license
choco install chocolatey-license --source $NugetRepositoryUrl --confirm

### b. Disable The Licensed Source ###
#### The licensed source cannot be removed, so it must be disabled.
#### This must occur after the license has been set by the license package.
if ("chocolatey-license" -in (choco list --localonly --limitoutput | ConvertFrom-Csv -Header "Name" -Delimiter "|").Name) {
    choco source disable --name chocolatey.licensed
} else {
    Write-Warning "Not disabling 'chocolatey.licensed' feed, as Chocolatey-License has not been installed."
}

### c. Ensure Chocolatey Licensed Extension ###
#### You will have downloaded the licensed extension to your internal repository
#### as you have disabled the licensed repository in step 5b.

#### Ensure the chocolatey.extension package (aka Chocolatey Licensed Extension)
if ("chocolatey-license" -in (choco list --localonly --limitoutput | ConvertFrom-Csv -Header "Name" -Delimiter "|").Name) {
    choco install chocolatey.extension --source $NugetRepositoryUrl --confirm
} else {
    Write-Warning "Not installing 'chocolatey.extension', as Chocolatey-License has not been installed."
}

#requires -Modules cChoco
## 1. REQUIREMENTS ##
### Here are the requirements necessary to ensure this is successful.

### a. Internal/Private Cloud Repository Set Up ###
#### You'll need an internal/private cloud repository you can use. These are
####  generally really quick to set up and there are quite a few options.
####  Chocolatey Software recommends Nexus, Artifactory Pro, or ProGet as they
####  are repository servers and will give you the ability to manage multiple
####  repositories and types from one server installation.

### b. Download Chocolatey Package and Put on Internal Repository ###
#### You need to have downloaded the Chocolatey package as well.
####  Please see https://chocolatey.org/install#organization

### c. Other Requirements ###
#### i. Requires chocolatey\cChoco DSC module to be installed on the machine compiling the DSC manifest
#### NOTE: This will need to be installed before running the DSC portion of this script
if (-not (Get-Module cChoco -ListAvailable)) {
    $null = Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
    if (($PSGallery = Get-PSRepository -Name PSGallery).InstallationPolicy -ne "Trusted") {
        Set-PSRepository -Name PSGallery -InstallationPolicy Trusted
    }
    Install-Module -Name cChoco
    if ($PSGallery.InstallationPolicy -ne "Trusted") {
        Set-PSRepository -Name PSGallery -InstallationPolicy $PSGallery.InstallationPolicy
    }
}

#### ii. Requires a hosted copy of the install.ps1 script
##### This should be available to download without authentication.
##### The original script can be found here: https://community.chocolatey.org/install.ps1

Configuration ChocolateyConfig {
## 2. TOP LEVEL VARIABLES ##
    param(
### a. Your internal repository url (the main one). ###
####  Should be similar to what you see when you browse
#### to https://community.chocolatey.org/api/v2/
        $NugetRepositoryUrl      = "INTERNAL REPO URL",

### b. Chocolatey nupkg download url ###
#### This url should result in an immediate download when you navigate to it in
#### a web browser
        $ChocolateyNupkgUrl      = "INTERNAL REPO URL/package/chocolatey.2.2.2.nupkg",

### c. Internal Repository Credential ###
#### If required, add the repository access credential here
#        $NugetRepositoryCredential = [PSCredential]::new(

## 3. ENSURE CHOCOLATEY IS INSTALLED ##
### Ensure Chocolatey is installed from your internal repository
        Environment chocoDownloadUrl {
            Name  = "chocolateyDownloadUrl"
            Value = $ChocolateyNupkgUrl
        }

            InstallDir = Join-Path $env:ProgramData "chocolatey"
            ChocoInstallScriptUrl = $ChocolateyInstallPs1Url
        }

## 4. CONFIGURE CHOCOLATEY BASELINE ##
### a. FIPS Feature ###
#### If you need FIPS compliance - make this the first thing you configure
#### before you do any additional configuration or package installations
#        cChocoFeature featureFipsCompliance {
#            FeatureName = "useFipsCompliantChecksums"
#        }

### b. Apply Recommended Configuration ###

#### Move cache location so Chocolatey is very deterministic about
#### cleaning up temporary data and the location is secured to admins
        cChocoConfig cacheLocation {
            DependsOn  = "[cChocoInstaller]installChocolatey"
            ConfigName = "cacheLocation"
            Value      = "C:\ProgramData\chocolatey\cache"
        }

#### Increase timeout to at least 4 hours
        cChocoConfig commandExecutionTimeoutSeconds {
            DependsOn  = "[cChocoInstaller]installChocolatey"
            ConfigName = "commandExecutionTimeoutSeconds"
            Value      = 14400
        }

#### Turn off download progress when running choco through integrations
        cChocoFeature showDownloadProgress {
            DependsOn   = "[cChocoInstaller]installChocolatey"
            FeatureName = "showDownloadProgress"
            Ensure      = "Absent"
        }

### c. Sources ###
#### Remove the default community package repository source
        cChocoSource removeCommunityRepository {
            DependsOn  = "[cChocoInstaller]installChocolatey"
            Name       = "chocolatey"
            Ensure     = "Absent"
        }

#### Add internal default sources
#### You could have multiple sources here, so we will provide an example
#### of one using the remote repo variable here.
#### NOTE: This EXAMPLE may require changes
        cChocoSource addInternalSource {
            DependsOn  = "[cChocoInstaller]installChocolatey"
            Name        = "ChocolateyInternal"

            Credentials = $NugetRepositoryCredential
            Priority    = 1
        }

### b. Keep Chocolatey Up To Date ###
#### Keep chocolatey up to date based on your internal source
#### You control the upgrades based on when you push an updated version
####  to your internal repository.
#### Note the source here is to the OData feed, similar to what you see
####  when you browse to https://community.chocolatey.org/api/v2/
        cChocoPackageInstaller updateChocolatey {
            DependsOn   = "[cChocoSource]addInternalSource", "[cChocoSource]removeCommunityRepository"

        cChocoPackageInstaller chocolateyLicense {
            DependsOn = "[cChocoPackageInstaller]updateChocolatey"
            Name      = "chocolatey-license"
        }

### b. Disable The Licensed Source ###
#### The licensed source cannot be removed, so it must be disabled.
#### This must occur after the license has been set by the license package.
        Script disableLicensedSource {
            DependsOn  = "[cChocoPackageInstaller]chocolateyLicense"

Description

Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes. It supports multiple programming paradigms beyond object-oriented programming, such as procedural and functional programming. Python combines remarkable power with very clear syntax. It has interfaces to many system calls and libraries, as well as to various window systems, and is extensible in C or C++. It is also usable as an extension language for applications that need a programmable interface. Finally, Python is portable: it runs on many Unix variants including Linux and macOS, and on Windows.

History and License
*******************


History of the software
=======================

Python was created in the early 1990s by Guido van Rossum at Stichting
Mathematisch Centrum (CWI, see https://www.cwi.nl/) in the Netherlands
as a successor of a language called ABC.  Guido remains Python's
principal author, although it includes many contributions from others.

In 1995, Guido continued his work on Python at the Corporation for
National Research Initiatives (CNRI, see
https://www.cnri.reston.va.us/) in Reston, Virginia where he released
several versions of the software.

In May 2000, Guido and the Python core development team moved to
BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
year, the PythonLabs team moved to Digital Creations (now Zope
Corporation; see https://www.zope.org/).  In 2001, the Python Software
Foundation (PSF, see https://www.python.org/psf/) was formed, a non-
profit organization created specifically to own Python-related
Intellectual Property.  Zope Corporation is a sponsoring member of the
PSF.

All Python releases are Open Source (see https://opensource.org/ for
the Open Source Definition). Historically, most, but not all, Python
releases have also been GPL-compatible; the table below summarizes the
various releases.

Note:

  GPL-compatible doesn't mean that we're distributing Python under the
  GPL.  All Python licenses, unlike the GPL, let you distribute a
  modified version without making your changes open source. The GPL-
  compatible licenses make it possible to combine Python with other
  software that is released under the GPL; the others don't.

Thanks to the many outside volunteers who have worked under Guido's
direction to make these releases possible.

   Modified by Jack Jansen, CWI, July 1995:
   - Use binascii module to do the actual line-by-line conversion

     version is still 5 times faster, though.
   - Arguments more compliant with Python standard

Additionally, the Windows and macOS installers for Python may include
a copy of the OpenSSL libraries, so we include a copy of the OpenSSL
license here:

    Open Source licenses. In case of any license issues related to OpenSSL

History and License
*******************


History of the software
=======================

Python was created in the early 1990s by Guido van Rossum at Stichting
Mathematisch Centrum (CWI, see https://www.cwi.nl/) in the Netherlands
as a successor of a language called ABC.  Guido remains Python's
principal author, although it includes many contributions from others.

In 1995, Guido continued his work on Python at the Corporation for
National Research Initiatives (CNRI, see
https://www.cnri.reston.va.us/) in Reston, Virginia where he released
several versions of the software.

In May 2000, Guido and the Python core development team moved to
BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
year, the PythonLabs team moved to Digital Creations (now Zope
Corporation; see https://www.zope.org/).  In 2001, the Python Software
Foundation (PSF, see https://www.python.org/psf/) was formed, a non-
profit organization created specifically to own Python-related
Intellectual Property.  Zope Corporation is a sponsoring member of the
PSF.

All Python releases are Open Source (see https://opensource.org/ for
the Open Source Definition). Historically, most, but not all, Python
releases have also been GPL-compatible; the table below summarizes the
various releases.

+------------------+----------------+--------------+--------------+-------------------+

Note:

  GPL-compatible doesn't mean that we're distributing Python under the
  GPL.  All Python licenses, unlike the GPL, let you distribute a
  modified version without making your changes open source. The GPL-
  compatible licenses make it possible to combine Python with other
  software that is released under the GPL; the others don't.

Thanks to the many outside volunteers who have worked under Guido's
direction to make these releases possible.


Terms and conditions for accessing or otherwise using Python
============================================================

History and License
*******************


History of the software
=======================

Python was created in the early 1990s by Guido van Rossum at Stichting
Mathematisch Centrum (CWI, see https://www.cwi.nl/) in the Netherlands
as a successor of a language called ABC.  Guido remains Python's
principal author, although it includes many contributions from others.

In 1995, Guido continued his work on Python at the Corporation for
National Research Initiatives (CNRI, see
https://www.cnri.reston.va.us/) in Reston, Virginia where he released
several versions of the software.

In May 2000, Guido and the Python core development team moved to
BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
year, the PythonLabs team moved to Digital Creations (now Zope
Corporation; see https://www.zope.org/).  In 2001, the Python Software
Foundation (PSF, see https://www.python.org/psf/) was formed, a non-
profit organization created specifically to own Python-related
Intellectual Property.  Zope Corporation is a sponsoring member of the
PSF.

All Python releases are Open Source (see https://opensource.org/ for
the Open Source Definition). Historically, most, but not all, Python
releases have also been GPL-compatible; the table below summarizes the
various releases.

+------------------+----------------+--------------+--------------+-------------------+

Note:

  GPL-compatible doesn't mean that we're distributing Python under the
  GPL.  All Python licenses, unlike the GPL, let you distribute a
  modified version without making your changes open source. The GPL-
  compatible licenses make it possible to combine Python with other
  software that is released under the GPL; the others don't.

Thanks to the many outside volunteers who have worked under Guido's
direction to make these releases possible.

History and License
*******************


History of the software
=======================

Python was created in the early 1990s by Guido van Rossum at Stichting
Mathematisch Centrum (CWI, see https://www.cwi.nl/) in the Netherlands
as a successor of a language called ABC.  Guido remains Python's
principal author, although it includes many contributions from others.

In 1995, Guido continued his work on Python at the Corporation for
National Research Initiatives (CNRI, see
https://www.cnri.reston.va.us/) in Reston, Virginia where he released
several versions of the software.

In May 2000, Guido and the Python core development team moved to
BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
year, the PythonLabs team moved to Digital Creations (now Zope
Corporation; see https://www.zope.org/).  In 2001, the Python Software
Foundation (PSF, see https://www.python.org/psf/) was formed, a non-
profit organization created specifically to own Python-related
Intellectual Property.  Zope Corporation is a sponsoring member of the
PSF.

All Python releases are Open Source (see https://opensource.org/ for
the Open Source Definition). Historically, most, but not all, Python
releases have also been GPL-compatible; the table below summarizes the
various releases.

+------------------+----------------+--------------+--------------+-------------------+

Note:

  GPL-compatible doesn't mean that we're distributing Python under the
  GPL.  All Python licenses, unlike the GPL, let you distribute a
  modified version without making your changes open source. The GPL-
  compatible licenses make it possible to combine Python with other
  software that is released under the GPL; the others don't.

Thanks to the many outside volunteers who have worked under Guido's
direction to make these releases possible.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
