What is Rapidoid?

Rapidoid is an extremely fast HTTP server and modern Java web framework / application container, with a strong focus on high productivity and high performance.

How to use this image

To quickly start Rapidoid and display some basic usage help, run:

Rapidoid can be used in different ways:

• as a web tool, to quickly prototype RESTful web services from the command line • as a HTTP server, to serve static resources • as a Java web application framework/container, to deploy a web application JAR

Quickly prototyping SQL-powered RESTful web services

To quickly prototype SQL-powered RESTful web services from the command line, you need to link the database container to the Rapidoid container. The MySQL containers should be linked under name mysql, and PostgreSQL containers under name postgres.

This example starts a new MySQL container and links it under name mysql in the Rapidoid container, where a RESTful service is defined by specifying SQL query for the route GET /users. The service returns the result (a list of MySQL users) in JSON format.

Note: Please wait for several seconds for the MySQL database to initialize, and then you can visit http://localhost:8888/users (or http://your-host:8888/users) in your web browser.

Syntax for the service prototyping arguments:

Serving static files

Rapidoid will automatically serve static files from the folders: /app/static. To serve the contents of the /your-www-root directory, please mount it as /app/static:

Configuration

Rapidoid will try to read the configuration from /app/config.yml. The configuration can also be specified with command-line arguments or environment variables.

To configure a custom port (by default 8888) for the default and the Admin server, run the following command. If rapidoid-admin.port is not configured, the default server is also used as Admin server, so only one port will be opened (rapidoid.port).

Then you can visit http://localhost:4444/\_ping (or http://your-host:4444/_ping) and http://localhost:9999/\_status (or http://your-host:9999/_status) in your web browser.

The same setup can be configured with environment variables:

For more details, please see the full list of configuration options and their default values.

Security

Rapidoid's HMAC-based security token mechanism requires all containers to share the same secret key when scaling out a web application:

While this is an easy way to get started, for security reasons it is recommended to store the secret key in the /app/config.yml file, with proper permissions.

Note: For production use, you must replace your-secret-key with a real, private secret key.

Note: If no secret key is specified, a random secret key will be generated, which is acceptable when deploying a single container.

Full bootstrap of Rapidoid's Admin Center

To bootstrap a full-blown Admin Center in Rapidoid, you will also need to configure a password for the built-in admin user:

Please replace admin-pass with a real password for the admin user. Then you can login to the Admin Center by visiting http://localhost:8888/\_ (or http://your-host:8888/_) in your web browser.

Note: For production use, you must replace your-secret-key with a real, private secret key (please see the Security section).
