+You can provide your own Docker image. The Docker image that will be used create the web application container is specified in the @docker_image@ file in the root of the collection. You can also specify @--image@ on the command @arv-web@ line to choose the docker image (this will override the contents of @docker_image@).

+h3. Reloading the web service
+
+Stopping the Docker container and starting it again can result in a small amount of downtime. When the collection containing a new or updated web application uses the same Docker image as the currently running web application, it is possible to avoid this downtime by keeping the existing container and only reloading the web server. This is accomplished by providing a file called @reload@ in the root of the collection, which should contain the commands necessary to reload the web server inside the container.
