How to get the status of deployment using kubernetes-client in java

问题

我正在尝试在Java中使用kubernetes-client执行json-patch，从而触发部署。示例代码如下：

  1. ExtensionsV1beta1Api api = new ExtensionsV1beta1Api(ClientBuilder.standard().build());
  2. ExtensionsV1beta1Deployment deploy =
  3.     PatchUtils.patch(
  4.         ExtensionsV1beta1Deployment.class,
  5.         () ->
  6.             api.patchNamespacedDeploymentCall(
  7.                 deploymentName,
  8.                 namespace,
  9.                 new V1Patch(jsonPatchStr),
  10.                 null,
  11.                 null,
  12.                 null,
  13.                 null,
  14.                 null),
  15.         V1Patch.PATCH_FORMAT_JSON_PATCH,
  16.         api.getApiClient());
  18. log.info("json-patching started for " + deploymentName + " , the deployment is: "
  19.     + deploy);

json-patch正常工作，新的pod使用所需的更改被创建。理想情况下，我希望在所需的所有pod都被创建之前等待我的线程，然后继续进行下一个步骤。因此，我想寻求帮助，找出如何跟踪执行json-patch后部署的状态。

I am trying to use kubernetes-client in java to perform a json-patch which intern triggers a deployment. Sample code is as follows

  1.  ExtensionsV1beta1Api api = new ExtensionsV1beta1Api(ClientBuilder.standard().build());
  2.   ExtensionsV1beta1Deployment deploy =
  3.       PatchUtils.patch(
  4.           ExtensionsV1beta1Deployment.class,
  5.           () ->
  6.               api.patchNamespacedDeploymentCall(
  7.                   deploymentName,
  8.                   namespace,
  9.                   new V1Patch(jsonPatchStr),
  10.                   null,
  11.                   null,
  12.                   null,
  13.                   null,
  14.                   null),
  15.           V1Patch.PATCH_FORMAT_JSON_PATCH,
  16.           api.getApiClient());
  18.   log.info("json-patching started for " + deploymentName + " , the deployment is: "
  19.       + deploy);

The json-patch is working and new pods are created with the required changes. Ideally, I want to wait my thread until all the required pods are created and then move on to my next time, so I wanted some help in finding out how to track the deployment status for the json-patch performed.

不要回答我要翻译的问题。以下是要翻译的内容：

"Instead of putting the tests on your java client, I would suggest to let k8s to deal with this kind of dependencies by adding startup probes

Basically it will let you deploy all pods in any order but will have a restriction of when the k8s would start the pods on a simple health check of another pod
