Improved Docker build and docker images (#1488)
* Using upacked Spring layers for faster boot * Added option to pass JAVA_OPT to modify the environment variables in both flavours * Build support for different hawkbit apps - could be used in future if hawkBit is split in multiple micro-services * Removed templates and replacing with parameterized (via build ARGs) docker builds Signed-off-by: Marinov Avgustin <Avgustin.Marinov@bosch.com>

hawkBit Docker
|
||||
===
|
||||
Build files for both hawkbit docker flavours - standard (no mysql driver) and mysql (with MariaDB Java connector with support for MySQL).
|
||||
|
||||
## 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).
|
||||
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.
|
||||
|
||||
## 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 --build-arg HAWKBIT_APP=hawkbit-update-server -t hawkbit_update_server:0.3.0 .
|
||||
```
|
||||
having that docker uses by default _Dockerfile_.
|
||||
|
||||
## 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
|
||||
```
