How to Use Client other than Go Client

Fluid using kube-openapi and swagger-codegen to support multiple clients, including Java and Python.

Java Client: https://github.com/fluid-cloudnative/fluid-client-java

how to generate

$ cd $GOPATH/src/github.com/fluid-cloudnative
$ hack/sdk/gen-sdk.sh

hack/sdk/gen-sdk.sh script will generate Java and Python client in sdk folder. If you want to generate other client, You can modify script by adding these code:

java -jar ${SWAGGER_CODEGEN_JAR} generate -i ${SWAGGER_CODEGEN_FILE} -l <language> -o ${JAVA_SDK_OUTPUT_PATH} -c ${SWAGGER_CODEGEN_CONF} --model-package com.github.fluid-cloudnative.fluid

How to Use

It is suggested that you should use ApiClient and CustomObjectsApi from io.kubernetes:client-java. The only thing you should import from fluid-cloudnative.fluid:fluid-client-java is com.github.fluid_cloudnative.fluid.*

import io.kubernetes.client.openapi.ApiClient;
import io.kubernetes.client.openapi.apis.CustomObjectsApi;

import com.github.fluid_cloudnative.fluid.*;

public class MyExample {

// generate this client from a kubeconfig file or something else
ApiClient apiClient;

public void createAlluxioRuntime(String namespace, AlluxioRuntime runtime) throws ApiException {
CustomObjectsApi customObjectsApi = new CustomObjectsApi(apiClient);
customObjectsApi.createNamespacedCustomObject(
AlluxioRuntime.group,
AlluxioRuntime.version,
namespace,
AlluxioRuntime.plural,
runtime,
"true"
);
}

public AlluxioRuntime getAlluxioRuntime(String namespace, String name) throws Exception {
CustomObjectsApi customObjectsApi = new CustomObjectsApi(apiClient);
Object obj = customObjectsApi.getNamespacedCustomObject(
AlluxioRuntime.group,
AlluxioRuntime.version,
namespace,
AlluxioRuntime.plural,
name
);
Gson gson = new JSON().getGson();
return gson.fromJson(gson.toJsonTree(obj).getAsJsonObject(), AlluxioRuntime.class);
}

/*
Note that currently ClientJava can only support merge-patch+json
*/
public void patchAlluxioRuntime(String namespace, String name, String patchBody) throws ApiException {
CustomObjectsApi customObjectsApi = new CustomObjectsApi(apiClient);
customObjectsApi.patchNamespacedCustomObject(
AlluxioRuntime.group,
AlluxioRuntime.version,
namespace,
AlluxioRuntime.plural,
name,
patchpatchBody.getBytes()ody
);
}
}
