Getting Started

Installing the package

Add to build.gradle.kt dependencies block.

dependencies {
    implementation("tech.s-co.hetznerkloud:0.1.+")
    // or if you always want the latest version
    implementation("tech.s-co.hetznerkloud:latest.release")
}

Usage

import tech.sco.hetznerkloud.CloudApiClient
import tech.sco.hetznerkloud.ApiToken
import tech.sco.hetznerkloud.request.FilterFields
import tech.sco.hetznerkloud.request.SortingFields
import tech.sco.hetznerkloud.request.SortingDirection

fun main() {
    
    runBlocking {
        val apiToken = ApiToken.load(Path("/some/path/token.txt"))

        val client = CloudApiClient(apiToken)
        
        client.servers.all(
            filter = setOf(Pair(FilterFields.Server.STATUS, "running")), 
            sorting = setOf(Pair(SortingFields.Server.CREATED, SortingDirection.DESC))
        ).map {
            println("Id: ${it.id}")
            println("Name: ${it.name}")
        }
    }
}

Error handling

You can find all the various errors in the src/kotlin/tech/sco/hetznerkloud/model/Error.kt file.

All errors are wrapped in the Failure throwable object which will also hold the request object that caused the error, that should help you in debugging potential issues.

import tech.sco.hetznerkloud.CloudApiClient
import tech.sco.hetznerkloud.ApiToken
import tech.sco.hetznerkloud.request.CreateSSHKey

fun main() {
    
    runBlocking {
        val apiToken = ApiToken.load(Path("/some/path/token.txt"))

        val client = CloudApiClient(apiToken)

        try {
            client.sshKeys.create(CreateSSHKey(name = "login key", labels = emptyMap()))
        } catch (f: Failure) {
            when {
                f.error is UnauthorizedError -> println(f.request!!.headers)
            }
        }
        
    }
}

Ktor client plugins

You can extend the behaviour of the Ktor client used under the hood by adding official or custom plugins.

By default, the following ones are installed and used by this library:

• Auth
• Content Negotiation
• Kotlinx Serialization

For example let's add retry behaviour with a plugin:

val client = CloudApiClient(ApiToken("xxx-xxx-xxx")) {
    install(HttpRequestRetry) {
        retryOnServerErrors(maxRetries = 5)
    }
}
