+# Dockerfiles
+
+Dockerfile2 is an alternative to the `Dockerfile` which is
+used with docker-compose.
+
+It allows an external configuration via an `application.properties`
+lying on the docker host and which is made available to the
+docker container via volumes.
+
+Build the image e.g. from within the backend folder with
+
+```
+$ docker build -t sonarquest-backend -f Docker/Dockerfile2 .
+```
+
+The image expects the configuration files to be in folder `/root/conf/`.
+
+Example setup with an external h2 file database:
+
+let `sqb` be the current directory.
+Define an `application.properties` in folder `sqb` with content
+
+```
+spring.datasource.url=jdbc:h2:file:/tmp/sonarQuest/sonarQuest
+```
+
+Start the container with
+
+```
+docker run -v `pwd`:/root/conf -v /tmp/sonarQuestDb:/tmp/sonarQuest sonarquest-backend
+```
+
+The h2 database file will then be created (or used) in the host's folder
+`/tmp/sonarQuestDb`.
