+# Airlift Docker Builder
+
+For modules that contain a file named `.build-airlift-docker`,
+the Maven properties below are used to generate a docker image during the
+package phase and to deploy/push that image during the delpoy phase.  This 
+[docker file](../airbase-docker/src/main/resources/AirliftDockerfile) is
+used to build the image.
+
+Note: modules must also contain `.build-airlift` so that the Airlift
+launcher tarball is generated. The Maven build will fail if this file
+is missing.
+
+## Maven Properties
+
+| Name | Default Value | Details |
+| ----- | ------------- | ------- |
+| air.docker.skip | false | skip all docker executions |
+| air.docker.skip-build | false | skip docker build |
+| air.docker.skip-deploy | false | skip docker deploy |
+| air.docker.skip-tag | false | skip docker tagging |
+| air.docker.verbose | false | enable verbose mode for dockerfile-maven-plugin |
