-# roundcubemail-docker
-Resources to build Docker images for Roundcube Webmail
+# Running Roundcube in a Docker Container
+
+The simplest method is to run the official image:
+
+```
+docker run -e ROUNDCUBEMAIL_DEFAULT_HOST=mail -d roundcube/roundcubemail
+```
+
+## Configuration/Environment Variables
+
+The following env variables can be set to configure your Roundcube Docker instance:
+
+`ROUNDCUBEMAIL_DEFAULT_HOST` - Hostname of the IMAP server to connect to
+
+`ROUNDCUBEMAIL_DEFAULT_PORT` - IMAP port number; defaults to `143`
+
+`ROUNDCUBEMAIL_SMTP_SERVER` - Hostname of the SMTP server to send mails
+
+`ROUNDCUBEMAIL_SMTP_PORT`  - SMTP port number; defaults to `587`
+
+`ROUNDCUBEMAIL_PLUGINS` - List of built-in plugins to activate. Defaults to `archive,zipdownload`
+
+`ROUNDCUBEMAIL_UPLOAD_MAX_FILESIZE` - File upload size limit; defaults to `5M`
+
+By default, the image will use a local SQLite database for storing user account metadata.
+It'll be created inside the `/var/www/html` directory and can be backed up from there. Please note that
+this option should not be used for production environments.
+
+### Connect to a MySQL Database
+
+The recommended way to run Roundcube is connected to a MySQL database. Specify the following env variables to do so:
+
+`ROUNDCUBEMAIL_DB_TYPE` - Database provider; currently supported: `mysql`, `pgsql`, `sqlite`
+
+`ROUNDCUBEMAIL_DB_HOST` - Host (or Docker instance) name of the database service; defaults to `mysql` or `postgres` depending on linked containers.
+
+`ROUNDCUBEMAIL_DB_USER` - The database username for Roundcube; defaults to `root` on `mysql`
+
+`ROUNDCUBEMAIL_DB_PASSWORD` - The password for the database connection
+
+`ROUNDCUBEMAIL_DB_NAME` - The database name for Roundcube to use; defaults to `roundcubemail`
+
+Before starting the container, please make sure that the supplied database exists and the given database user
+has privileges to create tables.
+
+Run it with a link to the MySQL host and the username/password variables:
+
+```
+docker run --link=mysql:mysql -d roundcube/roundcubemail
+```
+
+### Advanced configuration
+
+Apart from the above described environment variables, the Docker image also allows to add custom config files
+which are merged into Roundcube's default config. Therefore the image defines a volume `/var/roundcube/config`
+where additional config files (`*.php`) are searched and included. Mount a local directory with your config
+files - check for valid PHP syntax - when starting the Docker container:
+
+```
+docker run -v ./config/:/var/roundcube/config/ -d roundcube/roundcubemail
+```
+
+Check our wiki for a reference of [Roundcube config options](https://github.com/roundcube/roundcubemail/wiki/Configuration).
+
+## Building a Docker image
+
+Use the `Dockerfile` in this directory to build your own Docker image.
+It pulls the latest build of Roundcube Webmail from the Github download page and builds it on top of a `php:7.1-apache` Docker image.
+
+Build it from this directory with
+
+```
+docker build -t roundcubemail .
+```
