Azurite

npm version license Build Status

A lightweight server clone of Azure Blob, Queue, and Table Storage that simulates most of the commands supported by it with minimal dependencies.

Installation and Usage

NPM

In order to run Azurite you need Node.js >= 6.0 installed on your system. Azurite works cross-platform on Windows, Linux, and OS X.

After installation you can install Azurite simply with npm which is Node.js package management tool and which is included with every Node.js installation.

$ npm install -g azurite

Running Azurite

Simply start it with the following command:

$ azurite -l path/to/localfolder

This tells Azurite to store all data in a particular directory. If the -l option is ommitted it will use the current working directory. This also will start both blob storage and queue storage emulation in two different processes. You can also selectively start the different storage emulators.

For Blob Storage Emulator only:

$ azurite-blob -l path/to/azurite/workspace

For Queue Storage Emulator only:

$ azurite-queue

For Table Storage Emulator only:

$ azurite-table -l path/to/azurite/workspace

Nuget

Azurite is also available as Nuget package at https://www.nuget.org/packages/Azurite/. You can install it via the Package Manager Console with the following command:

PM> Install-Package Azurite

This will install Azurite to your current project and also immediately start it in a dedicated console window. Note that you do not need to install Node.js since Azurite is packaged into a single self-contained executable, thanks to pkg.

Docker image

Pulling from Docker Hub

Every release of Azurite starting with version 0.9.7 is available at Docker Hub and ready to be pulled with:

$ docker pull arafato/azurite

Please note that the latest tag will always refer to the latest release.

Build the Docker image

To build the Docker image yourself, execute the following:

$ docker build -t arafato/azurite .

Run the Docker image

To run the Docker image, execute the following command:

$ docker run -d -t -p 10000:10000 -p 10001:10001 -p 10002:10002 -v /path/to/folder:/opt/azurite/folder arafato/azurite

Configure the executable when running the container

By default, the container starts all services available (currently blob, queue, and table). Using the environment variable executable, specific executables can be specifed:

  • blob Start the Blob Storage Emulator only
  • queue Start the Azure Queue Storage Emulator only
  • table Start the Azure Table Storage Emulator only
Usage example:
$ docker run -e executable=blob -d -t -p 10000:10000 -v /path/to/folder:/opt/azurite/folder arafato/azurite

Usage with Azure Cross-Platform CLI 2.0

To perform blob storage operations using the 2.0 Azure cross-platform CLI, you need to operate with the appropriate connection string. The values within are based on the hardcoded Azure Storage Emulator values.

Example command to create a container:

$ az storage container create --name 'test' --connection-string 'DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;'

{
  "created": true
}

Current List of Command Line Options

-a

Enables sharedkey authentication check

-l c:\tmp\emulatorPath
--location c:\tmp\emulatorPath

Allows the specification of a path

--blobPort 101000

Sets the TCP Port for blob storage to the value following the argument.

--queuePort 10001

Sets the TCP Port for queue storage to the value following the argument.

--tablePort 10002

Sets the TCP Port for table storage to the value following the argument.

Contributions

What do I need to know to help?

If you are interested in making a code contribution and would like to learn more about the technologies that we use, check out the list below.

  • Azurite runs on Node.js. If you never worked with this technology before make sure to get yourself familiar with it. There are many good tutorials out there along with a comprehensive API documentation that will get you up to speed quickly! We are currently coding against Node.js v8.9.4 LTS
  • Azurite exposes its REST-based API via Express.js which is a "fast, unopinionated, minimalist web framework for Node.js.
  • Azurite uses LokiJS which is an in-memory data store with persistence. It serves as our central database to store metadata (names, properties, leases, etc.) about all objects put into Azurite.
  • Azurite makes heavy use of Bluebird which is a fully featured promises library with unmatched performance.

What TODOs are there?

We are using a combination of community feedback, and the Azure Storage Node package tests to validate Azurite's support of the Official Blob Storage REST API Specification.
We shall create issues based on failing tests to help direct and prioritize our development efforts.
See also section below: API Support.

Current bugs that need to be fixed are listed at our issues site on Github and tagged with a red label bug.

Issues which we think might be a good place for newcomers to start, are tagged with "good first issue".

Details on how to setup tests with the Azure Storage submodule, can be found under Testing with Azure Storage Node.

Need Help?

Be sure to check out the Microsoft Azure Developer Forums on MSDN or the Developer Forums on Stack Overflow if you have trouble with the provided code.

Contribute Code or Provide Feedback

If you would like to become an active contributor to this project please follow the instructions provided in Azure Projects Contribution Guidelines.

If you encounter any bugs with the library please file an issue in the Issues section of the project.

When sending pull requests, please send non-breaking PRs to the dev branch and breaking changes to the dev_breaking branch. Please do not make PRs against master.

  • Please include a Unit or Integration test with any code submission, this is a significant help when validating changes and helps reduce the time we need to spend on pull requests.

API Support

Currently, Azurite only supports the Blob Storage APIs, the Queue Storage API, and the Table Storage API.
Support for Azure Storage Files is planned, but currently not available.

The Standard Emulator Connection String is the same as required by Microsoft's Official Storage Emulator:

BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;

QueueEndpoint=http://127.0.0.1:10001/devstoreaccount1;

TableEndpoint=http://127.0.0.1:10002/devstoreaccount1;

Blob Storage - API Implementation Status

All DONE except:

  • Account SAS Support [TODO]
    See https://docs.microsoft.com/en-us/rest/api/storageservices/constructing-an-account-sas for specification

  • Get Blob Service Stats [TODO]
    Retrieves statistics related to replication for the Blob service. This operation is only available on the secondary location endpoint when read-access geo-redundant replication is enabled for the storage account.

  • Set Blob Tier [TODO] The Set Blob Tier operation sets the tier on a blob.

Queue Storage - API Implementation Status

All DONE.

Table Storage - API Implementation Status

ALL DONE except:

  • Get Table ACL [TODO]
  • Set Table ACL [TODO]
  • Entity Group Transaction (Batch Operation) [TODO]
