I am trying to get the instances information with Google Cloud API in Java. When I send the list request I get an exception. Can you tell me why I getting this exception?
I do not know about the protocol buffers and the error message does not give much clue.
Best regards,
The code:
InputStream stream = GoogleComputeServiceImpl.class.getResourceAsStream("/google_service_account.json");
FixedCredentialsProvider fixedCredentialsProvider = FixedCredentialsProvider.create(
ComputeEngineCredentials.fromStream(stream));
InstancesClient instancesClient = InstancesClient.create(InstancesSettings.newBuilder().setCredentialsProvider(fixedCredentialsProvider).build());
ListInstancesRequest request =
ListInstancesRequest.newBuilder()
.setProject("my-project-name")
.setReturnPartialSuccess(true)
.setZone("europe-west3-c")
.build();
try {
InstancesClient.ListPagedResponse list = instancesClient.list(request);
list.iterateAll().forEach(instance -> {
log.info("Instance: " + instance.getName());
log.info("Description: " + instance.getDescription());
log.info("Hostname: " + instance.getHostname());
instance.getNetworkInterfacesList().forEach(networkInterface -> {
log.info("Network interface: " + networkInterface.getName());
networkInterface.getAccessConfigsList().forEach(accessConfig -> {
log.info("Access config: " + accessConfig.getName());
log.info("IP: " + accessConfig.getNatIP());
});
});
});
} catch (Exception e) {
log.error("Error: ", e);
}
The error I got:
