Armadietto npm Build Status

⚠️ WARNING

Please do not consider armadietto production ready, this project is still considered experimental. As with any alpha-stage storage technology, you MUST expect that it will eat your data and take precautions against this. You SHOULD expect that its APIs and storage schemas will change before it is labelled stable.

What is this?

Armadietto is a RemoteStorage server written for Node.js.

This is a complete rewrite of reStore.

Installation

  1. Ensure you have a maintained version of Node installed.
  2. If you will be using Apache as a reverse proxy, ensure it is version 2.4.49 or later.
  3. Run npm -g i armadietto

Usage

See the notes directory for configuring a reverse proxy and other recipes.

Modular (new) Server

  • Streaming storage (documents don't have to fit in server memory)
  • S3-compatible storage (requires separate S3 server; AWS S3 allows documents up to 5 TB)
  • Can run multiple application servers to increase capacity to enterprise-scale
  • Bug Fix: correctly handles If-None-Match with ETag
  • Bug Fix: returns empty listing for nonexistent folder
  • Implements current spec: draft-dejong-remotestorage-22

See the modular-server-specific documentation for usage.

Monolithic (old) Server

  • Stores user documents in server file system
  • More thoroughly tested
  • Implements older spec: draft-dejong-remotestorage-01

See the monolithic-server-specific documentation for usage.

Storage security

In production, we recommend that you restrict access to the files managed by your armadietto server as much as possible. This is particularly true if you host your storage on a machine with other web applications; you need to protect your files in the event that one of those apps is exploited.

You should take these steps to keep your storage safe:

  • Pick a unique Unix user to run your server process; no other process on the box should run as this user: sudo useradd armadietto --system --no-create-home

  • Do not run other applications as root, or as any user that could access files owned by your armadietto user

  • Make sure the directory path/to/storage cannot be read, written or executed by anyone but this user: sudo chmod 0700 /path/to/storage && sudo chown armadietto:armadietto /path/to/storage

  • Do not run armadietto as root; if you need to bind to port 80 or 443 use a reverse proxy like nginx, Apache2, caddy, lighttpd or enable bind capability: setcap 'cap_net_bind_service=+ep' `which armadietto`

  • Ideally, run your storage inside a container or on a dedicated machine

If you're using the Redis backend, apply similar access restrictions to the database and to any files containing the database access credentials.

Serving over HTTPS

Since RemoteStorage is a system for storing arbitrary user-specific data, and since it makes use of OAuth 2.0, we strongly recommend you serve it over a secure connection. You can boot the server to listen for HTTP or HTTPS requests or both.
If armadietto is behind a reverse proxy on the same machine, the proxy can handle TLS, so armadietto only needs to set enable and force in the https configuration. The reverse proxy must set the header x-forwarded-proto (or x-forwarded-ssl or x-forwarded-scheme) in the request passed to Armadietto. Armadietto does not yet support the Forwarded header.

This configuration boots the app on two ports, one secure and one plaintext:

const server = new Armadietto({
  store: store,
  http: {
    host: '127.0.0.1',
    port: 8000
  },
  https: {
    force: true,
    host:  '127.0.0.1',
    port:  4343,
    key:   'path/to/ssl.key',
    cert:  'path/to/ssl.crt',
    ca:    'path/to/ca.pem'    // optional
  },
  logging: {
    stdout: ["debug"],
    log_files: ["error"],
    log_dir: "./some-log-dir"
  }

});

server.boot();

For example, if you use certificates from Lets Encrypt, you will set

    cert: "/etc/letsencrypt/live/domainname/cert.pem",
    key: "/etc/letsencrypt/live/domainname/privkey.pem"

where domainname is (usually) the DNS name of your server.

The force: true line in the https section means the app will:

  • Return HTTPS URLs in WebFinger responses
  • Force sign-up and OAuth login pages onto an HTTPS connection
  • Refuse to process POST authentication requests over insecure connections
  • Block insecure storage requests and revoke the client's access

Armadietto considers a request to be secure if:

  • armadietto itself acts as an SSL terminator and the connection to it is encrypted
  • The X-Forwarded-SSL header has the value on
  • The X-Forwarded-Proto header has the value https
  • The X-Forwarded-Scheme header has the value https

So you can have an SSL-terminating proxy in front of armadietto as long as it sets one of those headers, and does not let external clients set them. In this setup, you can set https.force = true but omit https.port; this means armadietto itself will not accept encrypted connections but will apply the above behaviour to enforce secure connections.

Debugging an installation

Set the environment DEBUG to enable logging. For example DEBUG=true armadietto -c /etc/armadietto/conf.json
