Rapidoid is an extremely fast HTTP server and modern Java web framework / application container, with a strong focus on high productivity and high performance. > [www.rapidoid.org](http://www.rapidoid.org)  # How to use this image To quickly start Rapidoid and display some basic usage help, run: ```console $ docker run --rm rapidoid --help ``` 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. ```console docker run -d --name some-mysql -e MYSQL_ROOT_PASSWORD=db-pass mysql docker run -it --rm \ -p 8888:8888 \ --link some-mysql:mysql \ rapidoid \ profiles=mysql \ jdbc.host=mysql \ jdbc.password=db-pass \ '/users <= SELECT user FROM mysql.user' ``` **Note:** Please wait for several seconds for the MySQL database to initialize, and then you can visit [http://localhost:8888/users](http://localhost:8888/users) (or `http://your-host:8888/users`) in your web browser. **Syntax for the service prototyping arguments**: ```console '[GET|POST|PUT|DELETE|PATCH] <= ' ``` ## 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`: ```console $ docker run -it --rm \ -p 8888:8888 \ -v /your-www-root:/app/static \ rapidoid ``` ## 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`). ```console $ docker run -it --rm \ -p 4444:4444 \ -p 9999:9999 \ rapidoid \ rapidoid.port=4444 \ rapidoid-admin.port=9999 \ app.services=ping \ admin.services=status ``` Then you can visit [http://localhost:4444/\_ping](http://localhost:4444/_ping) (or `http://your-host:4444/_ping`) and [http://localhost:9999/\_status](http://localhost:9999/_status) (or `http://your-host:9999/_status`) in your web browser. The same setup can be configured with environment variables: ```console $ docker run -it --rm \ -p 4444:4444 \ -p 9999:9999 \ -e RAPIDOID_PORT=4444 \ -e RAPIDOID-ADMIN_PORT=9999 \ rapidoid \ app.services=ping \ admin.services=status ``` For more details, please see the [full list of configuration options and their default values](http://www.rapidoid.org/the-default-configuration.html). ## Security Rapidoid's HMAC-based security token mechanism requires all containers to share the same secret key when scaling out a web application: ```console $ docker run -it --rm \ -p 8888:8888 \ -e SECRET=your-secret-key \ rapidoid ``` 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: ```console $ docker run -d \ --restart=always \ -p 8888:8888 \ -e SECRET=your-secret-key \ -e USERS_ADMIN_PASSWORD=admin-pass \ rapidoid \ admin.services=center ``` 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/\_](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). # How to extend this image (application JAR deployment) To use this image as base image for your web application, simply add your application JAR as `/app/app.jar`: ```dockerfile COPY /app/app.jar ``` # License View [license information](https://www.apache.org/licenses/LICENSE-2.0) for the software contained in this image.
