This project is a component of theOperator Framework, anopen source toolkit to manage Kubernetes native applications, calledOperators, in an effective, automated, and scalable way. Read more intheintroduction blog post.

Operators make it easy to manage complex statefulapplications on top of Kubernetes. However writing an operator today canbe difficult because of challenges such as using low level APIs, writingboilerplate, and a lack of modularity which leads to duplication.

Operator SDK is under Apache 2.0 license. See theLICENSE file for details.

To use java-operator-plugins for java operators we need to clone the operator-sdk repo.

• Add the kubebuilder plugin togo.mod

github.com/operator-framework/java-operator-plugins v0.0.0-20210225171707-e42ea87455e3

• Replace the java-operator-plugins path in go-mod pointing to the local dir of your kube-builder repo. Example.

github.com/operator-framework/java-operator-plugins => /Users/sushah/go/src/github.com/sujil02/java-operator-plugins

• Add the java-operator-sdk import

quarkusv1 "github.com/operator-framework/java-operator-plugins/pkg/quarkus/v1alpha"

• Introduce the java bundle inGetPluginsCLIAndRoot() method.

quarkusBundle, _ := plugin.NewBundle("quarkus"+plugins.DefaultNameQualifier, plugin.Version{Number: 1},&quarkusv1.Plugin{},)

• Add the created quarkusBundle to thecli.New

    cli.WithPlugins(ansibleBundle,gov2Bundle,gov3Bundle,helmBundle,quarkusBundle,),

go mod tidymake install

Now that the plugin is integrated with theoperator-sdk you can run theinit command to generate the sample java operator

• Use the quarkus plugin flag
• Pick the domain and project name as prefered.

operator-sdk init --plugins quarkus --domain xyz.com --project-name java-op

Once the operator is scaffolded check for the following files

├── PROJECT├── pom.xml└── src    └── main        ├── java        │   └── com        │       └── xyz        │           └── JavaOpOperator.java        └── resources            └── application.properties
