+hawkBit Docker Build
+===
+This directory contains docker files for building both hawkBit docker flavours:
+* _standard_ - hawkBit images without mysql driver
+* _mysql_ - with MariaDB Java connector with support for MySQL.
+  
+Both flavours of are almost the same, just mysql has in addition a MariaDB Java connector and is started, by default, with mysql Spring profile.
+
+For every flavour there are two build types:
+* _default_ - uses officially released hawkBit versions, downloading them from https://repo1.maven.org
+* _development/dev_ - uses the local maven repository with built by developer (or just downloaded from any maven repository) hawkBit applications 
+
+## Build overview
+Building images supports the following build arguments (i.e. ARG-s which could be passed using _--build-arg_):
+* _JAVA_VERSION_ - **[OPTIONAL, if not set a default is used]** the Java version of the eclipse-temurin jre-alpine base image to be used.   
+* _HAWKBIT_APP_ - **[OPTIONAL, if not set _hawkbit-update-server_ is used]** the application to be build. Currently, there is just _hawkbit-update-server_ but in future, if hawkBit is split to micro-services, there could be different micro-service apps.
+* _HAWKBIT_VERSION_ - **[OPTIONAL, if not set a default, should be the last officially released version, is used]** the application version
+* _CONTAINER_PORT_ - **[OPTIONAL, if not set 8080 is used]** on which the app opens the http server (if available)
+* _MARIADB_DRIVER_VERSION_ (mysql flavours only!) - **[OPTIONAL, if not set a default is used]** the version of MariaDB connector to be used
+
+Additionally, tge _development_ builds shall be started with docker build context the local maven repository
+
+## Build standard
+Standard flavour could be build, for example, with:
+```shell
+docker build --build-arg HAWKBIT_APP=hawkbit-update-server -t hawkbit_update_server:0.3.0 . -f Dockerfile
+```
+or just by:
+```shell
+docker build -t hawkbit_update_server:0.3.0 .
+```
+having that docker uses by default _Dockerfile_ and the _hawkbit-update-server_ is the default _HAWKBIT_APP_.
+
+To build development docker images, e.g. snapshot based, you could use something like:
+```shell
+docker build -t hawkbit_update_server:0.4.0-SNAPSHOT -f Dockerfile_dev ~/.m2/repository
+```
+Note that here you have to use your maven repository containing the hawkBit app as docker build context, in the example case _~/.m2/repository_ 
+
+## Build mysql
+Mysql flavour could be build, for example, with:
+```shell
+docker build --build-arg HAWKBIT_APP=hawkbit-update-server -t hawkbit_update_server:0.3.0-mysql . -f Dockerfile-mysql
+```
+or just by:
+```shell
+docker build --build-arg -t hawkbit_update_server:0.3.0-mysql . -f Dockerfile-mysql
+```
+having that the _hawkbit-update-server_ is the default _HAWKBIT_APP_.
+
+To build development docker images, e.g. snapshot based, you could use something like:
+```shell
+docker build -t hawkbit_update_server:0.4.0-SNAPSHOT-mysql -f Dockerfile_dev-mysql ~/.m2/repository
+```
+Note that here you have to use your maven repository containing the hawkBit app as docker build context, in the example case _~/.m2/repository_

-## Build overview
-Images are built using _Dockerfile_ or _Dockerfile-mysql_. They accept _ARG_ build parameters _JAVA_VERSION_, _HAWKBIT_APP_ (by default hawkbit-update-server), HAWKBIT_VERSION_ (by default the last released hawkBit version), _CONTAINER_PORT_ (by default 8080) on which the app opens the http server (if available) and (for mysql flavour only) _MARIADB_DRIVER_VERSION_ (by default 3.1.4 at the time of writing).
