This is a Kotlin DSL to create Kubernetes manifests in a typesafe and convenient way.
Replace K8S_VERSION with the desired Kubernetes version in the example below.
Copy that snippet to the dependencies section of your pom.
<dependency>
<groupId>de.loosetie.k8s</groupId>
<artifactId>lt-k8s-dsl</artifactId>
<version>1.0.0-K8S_VERSION</version>
</dependency>
Now in your code you're able to create Kubernetes manifests by using the k8sApi { ... } Function
import de.loosetie.k8s.dsl.k8sApi
import de.loosetie.k8s.dsl.util.jackson.Mappers.yamlPrinter
val manifests = k8sApi {
// your IDE will tell you, what's possible here
}
// the following lines will serialize the manifest definitions to yaml
maifests.forEach {
val jsonString = yamlPrinter
.writeValueAsString(it)
println(jsonString)
}
Good starting points are:

Just change the version of your lt-k8s-dsl dependency, and your compiler will tell you about breaking changes
