Azurite

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

Installation and Usage

In order to run Azurite you need Node.js >= 4.0 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

Then 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.

Docker image

Build the Docker image

To build the Docker image, 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 -v /path/to/folder:/opt/azurite/folder arafato/azurite

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 v6.10.x 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?

The current status of Azurite's support of the Official Blob Storage REST API Specification is listed in below section Blob Storage - API Implementation Status. Features that are still unimplemented are marked with [TODO]. Completed features are marked with [DONE].

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

How do I make a contribution?

Never made an open source contribution before? Wondering how contributions work in Azurite? Here's a quick rundown!

1. Find an issue that you are interested in addressing or a feature that you would like to add.

2. Fork the Azurite repository to your local GitHub organization. This means that you will have a copy of the repository under your-GitHub-username/azurite.

3. Clone the repository to your local machine using git clone https://github.com/github-username/azurite.git.

4. Create a new branch for your fix using git checkout -b branch-name-here. Make the appropriate changes for the issue you are trying to address or the feature that you want to add.

5. Use git add insert-paths-of-changed-files-here to add the file contents of the changed files to the "snapshot" git uses to manage the state of the project, also known as the index.

6. Use git commit -m "Insert a short message of the changes made here" to store the contents of the index with a descriptive message.

7. Push the changes to the remote repository using git push origin branch-name-here.

8. Submit a pull request to the upstream repository. Title the pull request with a short description of the changes made and the issue or bug number associated with your change. For example, you can title an issue like so "Added more log outputting to resolve #4352". In the description of the pull request, explain the changes that you made, any issues you think exist with the pull request you made, and any questions you have for the maintainer. It's OK if your pull request is not perfect (no pull request is), the reviewer will be able to help you fix any problems and improve it!

9. Wait for the pull request to be reviewed by a maintainer. Make changes to the pull request if the reviewing maintainer recommends them.

10. Celebrate your success after your pull request is merged!

API Support

Currently, Azurite only supports the Blob Storage APIs. Support for Azure Queues and Azure 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;
