A PowerShell Provider for Amazon S3 with C# source code
S3Nas for PowerShell is a partially functional PowerShell Provider for the Amazon Simple Storage Service (S3).
Things that work:
-
Creating a connection to the Amazon S3 service and displaying it as a drive, i.e. S3Nas:\
-
Listing the buckets for an account and listing the contents of a bucket with wildcard support. i.e. ls s*
-
Tab completion of bucket names and key names
-
Get-Item and Set-Item as a String or Byte[]
-
Get-Acl on a bucket or key
-
Rename-Item (currently requires downloading the object and uploading it with a different name - there is an example of doing this via script in the project) This is actually a limitation of the Amazon S3 service at the moment as key names are immutable.
Things that don't work:
-
Set-Acl (have not figured out ObjectSecurity yet)
-
Copy-Item (it appears you can only use this within a namespace so perhaps it is not possible to do the following: copy-item -path S3Nas:\bucket\key -destination C:\filename
To get it working, you will need to fill in your Access and Secret Access keys in the S3NasAuthentication.cs file and compile it. Then modify the paths in the registration script and execute it.
Unfortunately, the documentation on building PowerShell providers is still a bit sparse at this point. Suggestions from enlightened individuals are welcome.

Terrence,
Thanks -- it's still a work in progress, let me know your true feelings once you try it out. :-)

| Does powershell support the ability to 'run as a service' and therefore map a UNC path as a service? This is something we're looking to implement with the s3 cloud. |

Brad,
Powershell can be hosted in a runspace which is a Powershell instance embedded in a C# application.
You can write a C# application that is a service, so I would say that it is possible, although I haven't tried it.

just came across this - very useful thanks!
future versions should recurse to return more than 1000 objects in a bucket - you can achieve this with the following modification in S3NasProvider class
case PathType.Bucket:
WriteDebug("GetChildItems for bucket" + bucketName);
bool finished = false;
String marker = null;
while (!finished) {
ListBucketResponse bucketContents = S3NasConnection.Connection.listBucket(
bucketName, null, marker, 0, null);
foreach (ListEntry entry in bucketContents.Entries)
{
if (base.Stopping)
{
return;
}
WriteItemObject(entry, path, false);
marker = entry.Key;
}
if (!bucketContents.IsTruncated)
finished = true;
}
break; |

James,
Good idea, there are lots of improvements that it needs! I haven't got back to working on it much but I did want to get the idea out there...
I've been thinking of plugging in ThreeSharp to handle the actual data access and just concentrate on the Powershell integration. |
