I want to use JDK to call the rollback function of deploy, but after checking the source code, I failed. I want to implement the k8s command as an example kubectl rollout history deployment example-nginx --revision=2 -n nss #3921
Description
Hello, I have written a large number of test cases on my end, but none of them were able to successfully roll back using Kubernetes Java JDK. I hope that experts can provide help. Below is my test case code and environment
K8s version is: 1.21
Example of Writing:
` @test
public void rollbackDeploymentTest() {
ApiClient apiClient = kubeClient.getApiClient(null);
Configuration.setDefaultApiClient(apiClient);
AppsV1Api appsV1Api = new AppsV1Api(apiClient);
String deploymentName = "example-nginx";
String namespace = "xxx-test";
String revision = "4";
try {
// Deployment
V1Deployment deployment = appsV1Api.readNamespacedDeployment(deploymentName, namespace).execute();
if (deployment == null) {
System.err.println("not Deployment：" + deploymentName);
}
// Update Annotation, trigger rollback
deployment.getMetadata().getAnnotations().put("deployment.kubernetes.io/revision", revision);
// Update Deployment
appsV1Api.replaceNamespacedDeployment(deploymentName, namespace, deployment);
System.out.println("Rollback successful！");
} catch (ApiException e) {
// 打印详细错误日志
System.err.println(" Deployment : " + e.getResponseBody());
e.printStackTrace();
}
}
@Test
public void test(){
ApiClient apiClient = kubeClient.getApiClient(null);
Configuration.setDefaultApiClient(apiClient);
AppsV1Api appsV1Api = new AppsV1Api(apiClient);
String deploymentName = "example-nginx";
String namespace = "xxx-test";
String revision = "3";
Map<String, Object> patch = new HashMap<>();
Map<String, Object> spec = new HashMap<>();
Map<String, Object> rollbackTo = new HashMap<>();
rollbackTo.put("revision", revision);
spec.put("rollbackTo", rollbackTo);
patch.put("spec", spec);
String jsonPatch = JsonUtils.toJson(patch);
try {
V1Patch v1Patch = new V1Patch(jsonPatch);
// Use merge patch+json format
appsV1Api.patchNamespacedDeployment(deploymentName, namespace, v1Patch);
PatchUtils.patch(V1Deployment.class, () -> appsV1Api.patchNamespacedDeployment(deploymentName, namespace, v1Patch).fieldManager("kubectl-rollout").buildCall(null), V1Patch.PATCH_FORMAT_STRATEGIC_MERGE_PATCH, apiClient);
} catch (ApiException e) {
e.printStackTrace();
}
}`
