# hawkBit DDI Server (EXPERIMENTAL!)
|
|
|
|
The hawkBit DDI Server is a standalone spring-boot application with an embedded servlet container. It should be started
|
|
with at least hawkbit-mgmt-server.
|
|
|
|
## On your own workstation
|
|
|
|
### Run
|
|
|
|
```bash
|
|
java -jar hawkbit-runtime/hawkbit-ddi-server/target/hawkbit-ddi-server-*-SNAPSHOT.jar
|
|
```
|
|
|
|
_(Note: you have to add the JDBC driver also to your class path if you intend to use another database than H2.)_
|
|
|
|
Or:
|
|
|
|
```bash
|
|
run org.eclipse.hawkbit.app.ddi.DDIStart
|
|
```
|
|
|
|
### Usage
|
|
|
|
The Management API can be accessed via http://localhost:8081/rest/v1
|
|
The root url http://localhost:8081 will redirect directly to the Swagger Management UI
|
|
|
|
### Clustering (Experimental!!!)
|
|
|
|
The micro-service instances are configured to communicate via Spring Cloud Bus. You could run multiple instances of any
|
|
micro-service but hawkbit-mgmt-server. Management server run some schedulers which shall not run simultaneously - e.g.
|
|
auto assignment checker and rollouts executor. To run multiple management server instances you shall do some extensions
|
|
of hawkbit to ensure that they wont run schedulers simultaneously or you shall configure all instances but one to do not
|
|
run schedulers!
|
|
|
|
## Optional Protostuff for Sprign cloud bus
|
|
|
|
The micro-service instances are configured to communicate via Spring Cloud Bus. Optionally, you could
|
|
use [Protostuff](https://github.com/protostuff/protostuff) based message payload serialization for improved performance.
|
|
|
|
**Note**: If Protostuff is enabled it shall be enabled on all microservices!
|
|
|
|
Add/Uncomment to/in your `application.properties` :
|
|
|
|
```properties
|
|
spring.cloud.stream.bindings.springCloudBusInput.content-type=application/binary+protostuff
|
|
spring.cloud.stream.bindings.springCloudBusOutput.content-type=application/binary+protostuff
|
|
```
|
|
|
|
Add to your `pom.xml` :
|
|
|
|
```xml
|
|
<dependency>
|
|
<groupId>io.protostuff</groupId>
|
|
<artifactId>protostuff-core</artifactId>
