Summary

Blockchain is an emerging technology which has been gaining traction globally throughout the past few years. Industries like finance, logistics, and IoT are actively working on research and pilot projects using blockchain.

Fabric is a sub project under Hyperledger (a LinuxFoundation project), it is probably the most mature blockchain solution available now for business use cases.

The mission of Blockchain on Kubernetes (BoK) is to provide an end-to-end blockchain solution, from IaaS, CaaS, to Blockchain platform and Blockchain applications. It allows organizations to quickly collaborate and evaluate the new business models and processes by using the decentralized blockchain technology.

By using BoK, blockchain developers can use BoK command line tool or a GUI tool provided by BoK Fabric Tile to quickly set up an environment to build and test their blockchain applications.

fling logo of Sample Exchange PowerShell ISE Integration

Sample Exchange PowerShell ISE Integration

SampleExchangePowerCLI Module
A PowerShell Module that contains integration between VMware's new sample code repository Sample Exchange, and PowerShell ISE. Sample Exchange contains an ever growing catalog of PowerCLI samples and snippets, and this module uses Sample Exchange REST web services to allow a user to paste sample code into their editors directly in PowerShell ISE.
Pre-Requisites
PowerShell version 4 or later.
Installation
1) Download (or clone) all files comprising the module.
2) Create a folder for the module in your module folder path, e.g. C:\Users\username\Documents\WindowsPowerShell\Modules\SampleExchangePowerCLI
3) Place the module files in the above folder. The SampleExchangePowerCLI.psd1 and SampleExchangePowerCLI.psm1 files should be in the root of the folder
NOTE: If you create the folder in the path above, then PowerShell ISE (and regular PowerShell windows) will load the module.
If you don't want to do this, you can manually install the module by running the command
PS C:> Import-Module -Force -Verbose C:\local\path\where\you\extracted\SampleExchangePowerCLI
where SampleExchangePowerCLI is the folder containing SampleExchangePowerCLI.psd1 and SampleExchangePowerCLI.psm1.
4) Restart PowerShell ISE
5) If you would like to have Sample Exchange samples available via the PowerShell ISE Snippets feature, Go to "Add-ons" > "Sample Exchange" > "Sync Snippets"
This command is the equivilent of calling the "Sync-SampleExchangeSnippetsWithISE" method directly. It downloads all samples and registers them as "Snippets" in PowerShell ISE thus making them available for use in the editor when you issue the "CTRL + J" hot-key.
If you later decide that you do not like this, you can simply go to C:\Users<user>\Documents\WindowsPowerShell\Snippets and delete all of the VMW*.ps1xml files and the snippets will go away.
Usage
Selecting Either Add-ons > VMware Sample Exchange > Search Samples, or hitting "CTRL + SHIFT + S" will bring up a dialog box which lists all available PowerShell language samples by default. You can additionally enter a search term and click the "Search" button to additionally filter the list.
Select any sample from the list and click the "Insert in Editor" button to insert the given sample code at the location of the cursor in the editor that had focus when the dialog was opened (yes, it doesn't work to select another editor after the dialog is opened, sorry).
If you click "OK" the sample content is pasted in the shell. "Cancel" simply closes the window.

Get-Command -Module SampleExchangePowerCLI
