Gradle plugin examples

Description

The project demonstrates how gradle plugins can be written. There are examples of custom domain object container implementations

How to use

1. Pull the project and publish the plugins to maven local repository: gradlew publishToMavenLocal
2. apply a plugin to your project. The deployment plugin is an extension of the servers plugin. Thus, only one plugin can be applied.

build.gradle.kts

plugins {
  id("com.holovchenkoa.servers") version "0.0.0-SNAPSHOT"
  id("com.holovchenkoa.deployment") version "0.0.0-SNAPSHOT"
}

Plugins create a bunch of tasks that can be found in "servers" folder

Servers plugin

clusters {
    register("mssql-cluster") {
        nodes.add("mssql-node1")
        nodes.add("mssql-node2")
    }
    register("RDP-cluster") {
        // empty cluster
    }
}

serversConfiguration {
    this.servers.register("mssql-node1") {
        port = 1433
    }
    this.servers.register("mssql-node2") {
        port = 14330
    }
}

Deployment plugin

Plugin creates tasks dynamically based on added configuration. By default, only one ("AWS") server is added and only one "deployToAws" task is available in "servers" folder.

deploymentConfiguration {

val doNotDeploy = listOf("mssql-node1")
val azureServer = project.objects.newInstance(Azure::class.java, "myAzureCloud", doNotDeploy)

// Note: There are difference between Azure and AWS classes. 
// Thus Aws can be created only using  project.objects.named()
// And Azure can be created only using project.objects.newInstance()
//    val azureServer = project.objects.named(Azure::class.java, "myAzureCloudNamed")


cloudProviders.add(azureServer)

    // Custom domain named object implementation example
    cloudProviders.add(object : CloudProvider() {
        override fun deploy(servers: List<String>) {
            println("Deploying in private cloud: Servers count: ${servers.size}")
            servers.forEach(::println)
        }

        override fun getName(): String = "PrivateCloud"

    })
}

Tasks

To see available tasks execute gradlew tasks Here tasks names:
