I create a Cloud Run client, however, couldn't find a way to list a service that is deployed with Cloud Run on GKE (for Anthos).
- Create the client:
HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
GoogleCredentials credential = GoogleCredentials.getApplicationDefault();
credential.createScoped("https://www.googleapis.com/auth/cloud-platform");
HttpRequestInitializer requestInitializer = new HttpCredentialsAdapter(credential);
CloudRun.Builder builder = new CloudRun.Builder(httpTransport, jsonFactory, requestInitializer);
return builder.setApplicationName(applicationName)
.setRootUrl(cloudRunRootUrl)
.build();
} catch (IOException e) {
e.printStackTrace();
}
- try to list services:
services = cloudRun.namespaces().services()
.list("namespaces/default")
.execute()
.getItems();
My "hello" service is deploy on a GKE cluster under the namespace default. The above code doesn't work because the client always see "default" as project_id and complains about permission stuff. If I put the project_id rather than "default", permission errors are gone, but no services will be found.
I tried another project that does have Google fully-managed cloud run services, the same code returns result (with .list("namespaces/")).
How to access the service on GKE?
And my next question would be, how to programmatically create Cloud Run services on GKE?
Edit - for creating a service As I couldn't figure out how to interact with Cloud Run on GKE, I took a step back to try fully managed one. The following code to create a service fails, and the error message just doesn't provide much useful insight, how to make it work?
Service deployedService = null;
// Map<String,String> annotations = new HashMap<>();
// annotations.put("client.knative.dev/user-image","gcr.io/cloudrun/hello");
ServiceSpec spec = new ServiceSpec();
List<Container> containers = new ArrayList<>();
containers.add(new Container().setImage("gcr.io/cloudrun/hello"));
spec.setTemplate(new RevisionTemplate().setMetadata(new ObjectMeta().setName("hello-fully-managed-v0.1.0"))
.setSpec(new RevisionSpec().setContainerConcurrency(20)
.setContainers(containers)
.setTimeoutSeconds(100)
)
);
helloService.setApiVersion("serving.knative.dev/v1")
.setMetadata(new ObjectMeta().setName("hello-fully-managed")
.setNamespace("data-infrastructure-test-env")
// .setAnnotations(annotations)
)
.setSpec(spec)
.setKind("Service");
try {
deployedService = cloudRun.namespaces().services()
.create("namespaces/data-infrastructure-test-env",helloService)
.execute();
} catch (IOException e) {
e.printStackTrace();
response.add(e.toString());
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(response);
}
