PSDeploy
========

PSDeploy is a quick and dirty module to simplify PowerShell based deployments.

The idea is that you write a *.psdeploy.ps1 deployment configuration with sources and targets, and PSDeploy will deploy these.

Suggestions, pull requests, and other contributions would be more than welcome! See the [contributing guidlines](Contributing.md) for more info.

## Deployments

Invoking PSDeploy is very similar to running Invoke-Pester. Here's an example, Some.PSDeploy.ps1

```powershell
Deploy ActiveDirectory1 { # Deployment name. This needs to be unique. Call it whatever you want
By Filesystem { # Deployment type. See Get-PSDeploymentType
FromSource 'Tasks\AD\Some-ADScript.ps1', # One or more sources to deploy. Absolute, or relative to deployment.yml parent
'Tasks\AllOfThisDirectory'
To '\\contoso.org\share$\Tasks' # One or more destinations to deploy the sources to
Tagged Prod # One or more tags you can use to restrict deployments or queries
WithOptions @{
Mirror = $True # If the source is a folder, triggers robocopy purge. Danger
}
}
}
```

Let's pretend Some.PSDeploy.ps1 lives in C:\Git\Misc\Deployments. Here's what happens when we invoke a deployment:

```powershell
Invoke-PSDeploy -Path C:\Git\Misc
```

* We search for all *.*Deploy.ps1 or *PSDeploy.ps1 files under C:\Git\Misc, and find Some.PSDeploy.ps1. In this case, we have two resulting deployments, Some-ADScript.ps1, and AllOfThisDirectory
* We check the deployment type. Filesystem.
* We invoke the script associated with Filesystem Deployments, passing in the two deployments
* Relative paths are resolved by joining paths with C:\Git\Misc
* C:\Git\Misc\Tasks\AD\Some-ADScript.ps1 is copied to \\contoso.org\share$\Tasks with Copy-Item
* C:\Git\Misc\Tasks\AD\Tasks\AllOfThisDirectory is copied to \\contoso.org\share$\Tasks with robocopy, using /XO /E /PURGE (we only purge if mirror is true)

## Initial PSDeploy setup

```powershell
# One time setup
# Download the repository
# Unblock the zip
# Extract the PSDeploy folder to a module path (e.g. $env:USERPROFILE\Documents\WindowsPowerShell\Modules\)

#Simple alternative, if you have PowerShell 5, or the PowerShellGet module:
Install-Module PSDeploy

# Import the module.
Import-Module PSDeploy # Alternatively, Import-Module \\Path\To\PSDeploy

# Get commands in the module
Get-Command -Module PSDeploy

# Get help for the module and a command
Get-Help about_PSDeploy
Get-Help Invoke-PSDeploy -full
```

## More Information

The [PSDeploy docs](http://psdeploy.readthedocs.org/) will include more information, including:

* Examples for different DeploymentTypes - will try to keep these in sync with new types when they are added
* Illustrations of features like tags and dependencies
* Common scenarios (todo)
* How to write new PSDeploy DeploymentTypes
* Details on the PSDeploy Configuration Files

The blog posts ([one](http://ramblingcookiemonster.github.io/PSDeploy/), [two](http://ramblingcookiemonster.github.io/PSDeploy-Take-Two/)), and [three](http://ramblingcookiemonster.github.io/PSDeploy-Inception/) will become out of date over time, but may include helpful details

## Notes

Thanks go to:

* Scott Muc for [PowerYaml](https://github.com/scottmuc/PowerYaml), which we borrow for YAML parsing
* Boe Prox for [Get-FileHash](http://learn-powershell.net/2013/03/25/use-powershell-to-calculate-the-hash-of-a-file/), which we borrow for downlevel hash support in the deployment scripts
* Michael Greene, for the idea of using a DSL similar to Pester
* Folks writing new PSDeploy deployment types and contributing in other ways - thank you!
