+# Horizon Spring Parent
+
+This repository provides spring starter library that provides common functionality and models used by all Horizon components. 
+Basically it is a spring-boot-starter which provides some autoconfigurations for common tasks across the spring-boot components.
+
+* HorizonAutoConfiguration:
+  * HorizonMetricsHelperAutoConfiguration
+  * HorizonTracerAutoConfiguration
+  * CacheAutoConfiguration
+  * MongoAutoConfiguration
+  * KafkaAutoConfiguration
+* KubernetesClientAutoConfiguration
+
+Additionally, the horizon-spring-parent contains a core project with different classes and interfaces as well as constants 
+for topics in the area of caching (hazelcast), kafka, kubernetes, metrics, tracing and logging.
+
+## How to build
+
+This project uses gradle as build tool.
+
+To build the project, run the following command:  
+```
+./gradlew clean build
+```
+
+## How to use
+
+Add the following to your `build.gradle`:  
+```
+def horizonParentVersion = '1.0.0'
+
+dependencies {
+  implementation "de.telekom.eni:horizon-spring-boot-starter:${horizonParentVersion}"
+}
+```
+
+This library will provide an autoconfigured `HorizonTracer` bean that you can use in order to do tracing in an Horizon component.
+
+### Configuration parameters
+
+```yaml
+kubernetes:
+  enabled: true
+  rover:
+    token: # no default
+  kubeConfigPath:
+  informer:
+    resyncperiod:

+    groupId: default-group
+    partitionCount: 10
+    autoCreateTopics: false
+    autoOffsetReset: latest
+    isolationLevel: read_committed
+    maxPollRecords: 500
+    lingerMs: 0
+    acks: 1
+  cache:
+    enabled: false
+    name: cache
+    kubernetesServiceDns: # no default
+    deDuplication:
+      enabled: false
+      defaultCacheName: deDuplication
+      ttlInSeconds: 0
+      maxIdleInSeconds: 1800
+
+pandora:
+  tracing:
+    name: unsetLocalServiceName
+    debugEnabled: false
+```
+
+#### Special configurations
+
+* If a `spring.profiles.active` is set with 'dev' or 'test', the kubernetes client will be configured using a configuration 
+  file with the static path `KUBERNETES_DEV_CONFIG_FILE_PATH=kubernetes/config/config.laptop-dev-dev-system`
+* Within tracing all horizon pubsub components appear under a common service name `pandora.tracing.name` in the tracing 
+  system. This is useful to identify the service in the tracing system. The actual component name in the trace is also marked 
+  in the span as tag `component`. All pubsub components use the value `horizon`.
