```
docker build --rm -t registry.codemate.se/jetty .
```
+
+## Usage
+
+It's as simple as:
+
+```
+docker pull registry.codemate.se/jetty
+docker run -d registry.codemate.se/jetty
+```
+
+### Customize exposed port
+
+By default, the port `8080` (jetty) is mapped to a random port on the docker host. To customize, run:
+
+```
+docker run -p 8080:8080 -d registry.codemate.se/jetty
+```
+
+More info about port redirection can be found in the official Docker [documentation](http://docs.docker.io/en/latest/use/port_redirection/).
+
+### Persist application data on the docker host
+
+Jetty is configured to scan /opt/app/webapps when starting. To persist data to the docker host simply map a host directory to /opt/app. In the host directory create a webapps folder where place war, xml, or exploded webapps.
+
+MySQL is configured to store data files in '/opt/app/mysql-data' which will also cause it to be persisted to the host.
+
+```
+docker run -v /data/jetty-demo-app:/opt/app -d registry.codemate.se/jetty
+```
+
+### Running a different Jetty version
+
+By default, the container downloads and installs Jetty 9.2.2.v20140723 on the first boot. To specify which version to install, set the environment variable `JETTY_VERSION`:
+
+```
+docker run -e JETTY_VERSION=9.2.2.v20140723 -d registry.codemate.se/jetty
+```
+
+### Overriding Jetty files
+
+By providing an environment variable name `JETTY_OVERLAY` that points to a directory or URL of a gzipped tar file you can apply an overlay on the Jetty installation. A directory will be recursively copied, and a tarball will be unzipped and extracted in the root of the Jetty installation directory. The overlay enables you to add custom Jetty configurations.
+
+```
+docker run -e JETTY_OVERLAY=http://10.0.0.1/jetty-config.tgz -d registry.codemate.se/jetty
+docker run -e JETTY_OVERLAY=/opt/app/jetty-config -d registry.codemate.se/jetty
+```
+
+The overlay is fetched using curl so file URLs are valid:
+
+```
+JETTY_OVERLAY="file:////opt/app/jetty-config,tgz"
+```
+
+If you need to provide basic auth credentials simply prefix the url with the credentials, for example:
+
+```
+JETTY_OVERLAY="-u username:password http://10.0.0.1/jetty-config.tgz"
+```
+
+### Initializing MySQL
+
+By providing an environment variable name `MYSQL_INIT` that points to an SQL script you initialize the MySQL database.
+
+```
+docker run -e MYSQL_INIT=http://10.0.0.1/jetty-init.sql -d registry.codemate.se/jetty
+```
+
+Basic auth credentials and file URLs can be used as mentioned in the overlay section.
+
+### Combined options
+
+The following example shows the options we use to start a client site:
+
+```
+docker run \
+ --name ethbutik
+ -e JAVA_OPTIONS="-javaagent:/opt/app/lib/spring-agent-2.5.6.jar -Djavamonitor.uniqueid=10" \
+ -e EXIM=yes \
+ -v $DIR:/opt/app \
+ -p 8080:8080 \
+ -d registry.codemate.se/jetty
+```
+
+
