I am trying to learn how to test custom resource watcher in the Fabric8, I follow the example from this link https://github.com/r0haaaan/kubernetes-mockserver-demo/blob/master/src/test/java/io/fabric8/demo/kubernetes/mockserver/CustomResourceMockTest.java
My custom resource is "UserACL", I am using Java junit5, this is my fabric8 version.
implementation group: 'io.fabric8', name: 'kubernetes-client', version: '5.9.0'
implementation group: 'io.fabric8', name: 'kubernetes-api', version: '3.0.12'
testImplementation group: 'io.fabric8', name: 'kubernetes-server-mock', version: '5.9.0'
This test case failed, seem there is no any WatchEvent emitted, so countLatch never count down.
Could anybody help take a look and point out what's wrong here? Anything is missing in the following code. I appreciate it in advanced.

I checked your code; after resolving these problems I was able to get test working:
You're setting MockServer expectations using server.expect() for mocking watch call. But you've initialized KubernetesMockServer to enable CRUD mode (this doesn't require any expectations). You need to do this instead (see false being passed as second argument which disables CRUD mode):
#Rule
public KubernetesServer server = new KubernetesServer(true, false);
In Watch expectations path I can see that UserACL resource is a namespaced one. All Namespaced scope resources in KubernetesClient must implement io.fabric8.kubernetes.api.model.Namespaced interface:
#Group("custom.example.com")
#Version("v1")
#Kind("UserACL")
public static final class UserACL extends CustomResource<UserACLSpec, UserACLStatus> implements Namespaced { }
(Optional) I'm not sure whether you're using JUnit4 or JUnit5, I also had to update org.junit.Test to org.junit.jupiter.api.Test and also add #EnableRuleMigrationSupport annotation in order to run this test on my JUnit5 project:
#EnableRuleMigrationSupport
public class TestKafkaHelperUtilFourth {
After making these changes, test seemed to run okay for me:

I'm trying to connect and query to DB2 using vertx-db2-client, but it is not working. I'm using Spring Boot 2.6.6 and vertx-db2-client library to perform query in reactive way. I've created a class which implements CommandLineRunner

I'm not seeing any connection issues. The error that I see right after the deployment is below:
2022-04-11 15:35:11.740 INFO 2736 --- [ main] c.h.t.p.ServiceApp : Started ServiceApp in 3.746 seconds (JVM running for 4.719)
Failure: SQLState.NET_VCM_VCS_LENGTHS_INVALID: VCM and VCS lengths are mutually exclusive but both were set: vcsLen=255 vcmLen=12336
I'm not sure what is this "Failure: **" means. Can anyone please help me understand this and how to fix. Database connection parameters are correct. I've just masked here. I was following this documentation for the example.
I've recently started using testcontantainers for unit/integration testing database operations in my Quarkus webapp. It works fine except I cannot figure out a way to dynamically set the MySQL port in the quarkus.datasource.url application property. Currently I'm using the deprecated withPortBindings method to force the containers to bind the exposed MySQL port to port 11111 but the right way is to let testcontainers pick a random one and override the quarkus.datasource.url property.
My unit test class
#Testcontainers
#QuarkusTest
public class UserServiceTest {
#Container
private static final MySQLContainer MY_SQL_CONTAINER = (MySQLContainer) new MySQLContainer()
.withDatabaseName("userServiceDb")
.withUsername("foo")
.withPassword("bar")
.withUrlParam("serverTimezone", "UTC")
.withExposedPorts(3306)
.withCreateContainerCmdModifier(cmd ->
((CreateContainerCmd) cmd).withHostName("localhost")
.withPortBindings(new PortBinding(Ports.Binding.bindPort(11111), new ExposedPort(3306))) // deprecated, let testcontainers pick random free port
);
#BeforeAll
public static void setup() {
// TODO: use the return value from MY_SQL_CONTAINER.getJdbcUrl()
// to set %test.quarkus.datasource.url
LOGGER.info(" ********************** jdbc url = {}", MY_SQL_CONTAINER.getJdbcUrl());
}
// snip...
}
my application.properties:
%test.quarkus.datasource.url=jdbc:mysql://localhost:11111/userServiceDb?serverTimezone=UTC
%test.quarkus.datasource.driver=com.mysql.cj.jdbc.Driver
%test.quarkus.datasource.username=foo
%test.quarkus.datasource.password=bar
%test.quarkus.hibernate-orm.dialect=org.hibernate.dialect.MySQL8Dialect
The Quarkus guide to configuring an app describes how to programmatically read an application property:
String databaseName = ConfigProvider.getConfig().getValue("database.name", String.class);
but not how to set it. This tutorial on using test containers with Quarkus implicates it should be possible:
// Below should not be used - Function is deprecated and for simplicity of test , You should override your properties at runtime
SOLUTION:
As suggested in the accepted answer, I don't have to specify host and port in the datasource property. So the solution is to simply replace the two lines in application.properties:
%test.quarkus.datasource.url=jdbc:mysql://localhost:11111/userServiceDb
%test.quarkus.datasource.driver=com.mysql.cj.jdbc.Driver
with
%test.quarkus.datasource.url=jdbc:tc:mysql:///userServiceDb
%test.quarkus.datasource.driver=org.testcontainers.jdbc.ContainerDatabaseDriver
(and remove the unnecessary withExposedPorts and withCreateContainerCmdModifier method calls)
Please read the documentation carefully. The port can be omitted.
https://www.testcontainers.org/modules/databases/jdbc/
now (quarkus version 19.03.12) it can be a bit simpler.
Define test component that starts container and overrides JDBC props
import io.quarkus.test.common.QuarkusTestResourceLifecycleManager;
import org.testcontainers.containers.PostgreSQLContainer;
public class PostgresDatabaseResource implements QuarkusTestResourceLifecycleManager {
public static final PostgreSQLContainer<?> DATABASE = new PostgreSQLContainer<>("postgres:10.5")
.withDatabaseName("test_db")
.withUsername("test_user")
.withPassword("test_password")
.withExposedPorts(5432);
#Override
public Map<String, String> start() {
DATABASE.start();
return Map.of(
"quarkus.datasource.jdbc.url", DATABASE.getJdbcUrl(),
"quarkus.datasource.db-kind", "postgresql",
"quarkus.datasource.username", DATABASE.getUsername(),
"quarkus.datasource.password", DATABASE.getPassword());
}
#Override
public void stop() {
DATABASE.stop();
}
}
use it in test
import io.quarkus.test.common.QuarkusTestResource;
import io.quarkus.test.junit.QuarkusTest;
import org.junit.jupiter.api.Test;

I'm migrating a J2EE EJB application to Spring services. It's a desktop application which has a Swing GUI and to communicate to the J2EE server it uses RMI. I have created a simple spring service with spring boot which exports a service by using spring remoting, RMIServiceExporter. The client is a rich client and have a complicated architecture so i'm trying make minimum changes to it to call the spring rmi service.
So in summary I have a plain RMI client and a spring RMI server. I have learned that spring rmi abstracts pure java rmi so in my case they don't interoperate.
I will show the code below but the current error is this. Note that my current project uses "remote://". So after I have got this error I have also tried "rmi://". But, in both cases it gives this error.
javax.naming.CommunicationException: Failed to connect to any server. Servers tried: [rmi://yyy:1099 (No connection provider for URI scheme "rmi" is installed)]

I have searched for how we can interoperate spring rmi and plain/pure java rmi and i read several answers from similar questions at stackoverflow and web but i couldn't find anything useful or fits my case because even the best matched answer says only that it doesn't interoperate.
I thought that maybe i need to turn my swing gui client to spring by using spring boot but i couldn't be sure about application context since i don't want to break existing client code. So i have looked for maybe there is something like partial spring context so that maybe i can put only my CommManager.java client code to it and spring only manages this file.
And then I thought that maybe I need to change my RMI server to force spring to create some kind of plain/pure Java RMI instead of default spring RMI thing. I say thing because I read something about spring rmi that explains it's an abstraction over rmi and we can force it to create standard RMI stub.
While I'm searching for a solution i have encountered the Spring Integration but I couldn't understand it really since it looks like an other abstraction but it also tell something about adapters. Since I have seen "adapter" maybe it is used for this kind of integration/legacy code migration cases. But I couldn't go further.

So, my problem is how to interoperate pure/plain/standard java rmi client which is in a swing GUI with spring rmi server?
Edit #1:
By the way if you can provide further explanations or links about internal details of spring RMI stub creation and why they don't interoperate i will be happy. Thanks indeed.
And also, if you look at my getRemoteBean method which is from legacy code, how does this lookup string works? I mean where does rmi registry file or something resides at server or is this the default format or can i customize it?
Edit #2:
I have also tried this kind of lookup in the client:
private void initializeSpringEJBz(RemoteInvocation remoteInvocation) throws Exception {
HelloWorldRMI helloWorldService = (HelloWorldRMI) Naming.lookup("rmi://xxx:1099/helloworldrmi");
System.out.println("Output" + helloWorldService.sayHelloRmi("hello "));
//hw = remoteInvocation.getRemoteObject(HelloWorldRMI.class, "helloworldrmi");

Edit #3:
While I'm searching i found that someone in a spring forum suggested that to force spring to create plain java rmi stub we have to make some changes on the server side so i have tried this:
import java.rmi.server.RemoteObject;
public interface HelloWorldRMI extends **Remote** {
public String sayHelloRmi(String msg) throws **RemoteException**;
...
}
...
public class HelloWorldRMIimpl extends **RemoteObject** implements HelloWorldRMI {
...
}
Is the code above on the right path to solve the problem?
Beside that the first problem is the connection setup as you can see in the beginning of the question. Why i'm getting this error? What is the difference between "rmi://" and "remote://" ?
While I was trying to figure out, I could be able to find a solution. It's true that Spring RMI and Java RMI do not interoperate but currently i don't have enough knowledge to explain its cause. I couldn't find any complete explanation about internals of this mismatch yet.
The solution is using plain Java RMI in Spring backend by using java.rmi.*(Remote, RemoteException and server.UnicastRemoteObject).
java.rmi.server.UnicastRemoteObject is used for exporting a remote object with Java Remote Method Protocol (JRMP) and obtaining a stub that communicates to the remote object.
Edit:
I think this post is closely related to this interoperability issue: Java Spring RMI Activation
Spring doesn't support RMI activation. Spring includes an RmiServiceExporter for calling remote objects that contains nice improvements over standard RMI, such as not requiring that services extend java.rmi.Remote.
Solution:
This is the interface that server exports:
package com.xxx.ejb.interf;
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface HelloWorldRMI extends Remote {
public String sayHelloRmi(String msg) throws RemoteException;
}
and this is the implementation of exported class:
package com.xxx.proxyserver.service;
import com.xxx.ejb.interf.HelloWorldRMI;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import java.util.Date;
public class HelloWorldRMIimpl extends UnicastRemoteObject implements HelloWorldRMI {
public HelloWorldRMIimpl() throws RemoteException{
super();
}
#Override
public String sayHelloRmi(String msg) {
System.out.println("================Server Side ========================");
System.out.println("Inside Rmi IMPL - Incoming msg : " + msg);
return "Hello " + msg + " :: Response time - > " + new Date();
}
}
and the RMI Registry is:
package com.xxx.proxyserver;
import com.xxx.proxyserver.service.CustomerServiceImpl;
import com.xxx.proxyserver.service.HelloWorldRMIimpl;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.util.Collections;
#SpringBootApplication
public class ProxyServerApplication {
public static void main(String[] args) throws Exception
{
Registry registry = LocateRegistry.createRegistry(1200); // this line of code automatic creates a new RMI-Registry. Existing one can be also reused.
System.out.println("Registry created !");
registry.rebind("just_an_alias",new HelloWorldRMIimpl());
registry.rebind("path/to/service_as_registry_key/CustomerService", new CustomerServiceImpl());
SpringApplication app = new SpringApplication(ProxyServerApplication.class);
app.setDefaultProperties(Collections.singletonMap("server.port", "8084")); // Service port
app.run(args);
}
}
Client:
...
HelloWorldRMI helloWorldService = (HelloWorldRMI)Naming.lookup("rmi://st-spotfixapp1:1200/just_an_alias");
System.out.println("Output" + helloWorldService.sayHelloRmi("hello from client ... "));
...
I've recently tried using the new AWS DocumentDB service as my DB in a Spring application.
The cluster has been created in the same VPC as the EKS on which I deploy my application. Security groups allow connections between all nodes in the VPC.
AWS exposes a mongo URI like this for my DB cluster:
mongodb://<my-user>:<insertYourPassword>#<my-cluster-endpoint>:27017/?ssl_ca_certs=rds-combined-ca-bundle.pem&replicaSet=rs0
My question:
How do I make my Spring code work with this kind of connection?
I have tried adding the followig to my application.properties file:
spring.data.mongodb.uri=mongodb://<my-user>:<insertYourPassword>#<my-cluster-endpoint>:27017/admin?ssl_ca_certs=rds-combined-ca-bundle.pem&replicaSet=rs00
spring.data.mongodb.database=admin
server.ssl.key-store=classpath:rds-combined-ca-bundle.pem
And placing the PEM file in /src/main/resources
However the code still fails to connect to the DB cluster.
I get this message as an error: No server chosen by com.mongodb.client.internal.MongoClientDelegate
Followed by a Exception in monitor thread while connecting to server ...
And finally a timeout exception: com.mongodb.MongoSocketReadTimeoutException: Timeout while receiving message
It looks kind of like a security group issue but I have no problem connecting with mongo shell from the same EC2 running the Spring application Pod.
Any ideas?
As mentioned in the documentation,
By design, you access Amazon DocumentDB (with MongoDB compatibility) resources from an Amazon EC2 instance within the same Amazon VPC as the Amazon DocumentDB resources. However, suppose that your use case requires that you or your application access your Amazon DocumentDB resources from outside the cluster's Amazon VPC. In that case, you can use SSH tunneling (also known as "port forwarding") to access your Amazon DocumentDB resources.
Connect from outside VPC
Your Amazon DocumentDB cluster should be running in your default virtual private cloud (VPC). To interact with your Amazon DocumentDB cluster, you must launch an Amazon Elastic Compute Cloud (Amazon EC2) instance into your default VPC, in the same AWS Region where you created your Amazon DocumentDB cluster.
Follow the guide to connect to the cluster
AWS DocumentDB cluster
GitHub Reference: spring-boot-aws-documentdb
Update:
To connect through SSL, use below logic by setting SSL_CERTIFICATE pointing to aws region specific intermediate certificate.
This can be downloaded from SSL certs and copy it to base directory.
Alternatively, you can provide absolute path to the variable SSL_CERTIFICATE.

The answer provided by #Sunny Pelletier worked for me with a mashup of #Frank's answer in our Java setup.
So for me, I wanted a solution that worked for our local docker setup and for any of our AWS environments that have active profiles and other env vars set in our environment via the CDK.
I first started with a simple Configuration POJO to setup my properties outside the spring.data.mongo.* paradigm. You don't have to do this and can just let Spring handle it as it normally does to create the MongoClient.
My default local dev application.yml and corresponding config class.
mongo:
user: mongo
password: mongo
host: localhost
port: 27017
database: my-service
#Data
#Configuration
#ConfigurationProperties(prefix = "mongo")
public class MongoConnectConfig {
private int port;
private String host;
private String user;
private String database;
private String password;
}
Then, I created two AbstractMongoClientConfiguration child classes; one for local and one for non-local. The key here is that I didn't create my own MongoClient. The reason is because I want all the good Spring Boot initialization stuff that you get with the framework. For example, the auto-registration of all the converters and such.
Instead, I leveraged the customization hook provided by AbstractMongoClientConfiguration.configureClientSettings(MongoClientSettings.Builder builder) to then aggregate the custom settings like the .pem piece.
The other part is that I leveraged profiles to enable/disable the configurations to make it "seamless" for local developers; we don't use any profiles other than default for local development so it's easier to get setup without having to "know" so much from the start.

Lastly, we place the rds-combined-ca-bundle.pem in the src/main/resources/certs/ folder.
Side Notes:
Again, I believe you should be able to get away with using the default spring.data* properties and your MongoClient should have used them.
Ignore the #SneakyThrows here, I just did that for code brevity purposes, handle your checked exceptions as you see fit.
I guess we can see why Kotlin syntax can be considered "cleaner" huh? :)
I can confirm the solution provided by #Barath allows you to secure the AWS DocumentDB TLS connection inside the Java application itself. This is a much cleaner approach compared to the one described by AWS on https://docs.aws.amazon.com/documentdb/latest/developerguide/connect_programmatically.html which requires you to run a script on your server which is more complicated and difficult for automated deploys etc.
To further set up the connection itself in the Spring application I used the following #Configuration class, which allows you to connect to a local MongoDB for testing during development, and the AWS one once deployed with settings from the properties file.
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;

return dbName;
}

return MongoClients.create(mongoClientSettings);
}
private String getConnectionString() {
if (activeProfile.contains("local")) {
return String.format("mongodb://%s:%s/%s", dbUri, dbPort, dbName);
}
return String.format("mongodb://%s:%s#%s:%s/%s?ssl=true&replicaSet=rs0&readpreference=secondaryPreferred&retrywrites=false",
dbUser, dbPassword, dbUri, dbPort, dbName);
}
}
I actually faced the same issue as you did, but now AWS uses rds-combined-ca-bundle.pem which combines together many certificates into one.
If you don't want to create a trust-store using their outdated documentation, you can do it yourself and have the rds-combined-ca-bundle.pem into your application generating the key-store at runtime.
I managed to get this to work with this code sample. This has been tested with spring:2.4, mongo-driver: 4.1.1 and documentDB using mongo 4.0 compatibility.
val endOfCertificateDelimiter = "-----END CERTIFICATE-----"
// rds-combined-ca-bundle.pem contains more than one certificate. We need to add them all to the trust-store independantly.
val allCertificates = ClassPathResource("certificates/rds-combined-ca-bundle.pem").file.readText()
.split(endOfCertificateDelimiter)
.filter { it.isNotBlank() }
.map { it + endOfCertificateDelimiter }
val certificateFactory = CertificateFactory.getInstance("X.509")
val keyStore = KeyStore.getInstance(KeyStore.getDefaultType())
keyStore.load(null) // This allows us to use an in-memory key-store
allCertificates.forEachIndexed { index, certificate ->
val caCert = certificateFactory.generateCertificate(certificate.byteInputStream()) as X509Certificate
keyStore.setCertificateEntry("AWS-certificate-$index", caCert)
}
val trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm())
trustManagerFactory.init(keyStore)
val sslContext = SSLContext.getInstance("TLS")
sslContext.init(null, trustManagerFactory.trustManagers, null)
builder.applyToSslSettings {
it.enabled(true)
.context(sslContext)
}
Here is a solution that worked for me just call the setSslProperties method before you connect to your documentdb.
/**
* This method sets the SSL properties which specify the key store file, its type and password.
*
* #throws Exception
*/
private static void setSslProperties() throws Exception {
System.setProperty("javax.net.ssl.trustStore", createKeyStoreFile());
System.setProperty("javax.net.ssl.trustStoreType", KEY_STORE_TYPE);
System.setProperty("javax.net.ssl.trustStorePassword", DEFAULT_KEY_STORE_PASSWORD);
}
/**
* This method returns the path of the Key Store File needed for the SSL verification during the IAM Database Authentication to
* the db instance.
*
* #return
* #throws Exception
*/
private static String createKeyStoreFile() throws Exception {
return createKeyStoreFile(createCertificate()).getPath();
}
/**
* This method generates the SSL certificate.
*
* #return
* #throws Exception
*/
private static X509Certificate createCertificate() throws Exception {
final CertificateFactory certFactory = CertificateFactory.getInstance("X.509");
final ClassLoader classLoader = MyClass.class.getClassLoader();
final InputStream is = classLoader.getResourceAsStream(SSL_CERTIFICATE);
return (X509Certificate) certFactory.generateCertificate(is);
}
/**
* This method creates the Key Store File.
*
* #param rootX509Certificate - the SSL certificate to be stored in the KeyStore
* #return
* #throws Exception
*/
private static File createKeyStoreFile(final X509Certificate rootX509Certificate) throws Exception {
final File keyStoreFile = File.createTempFile(KEY_STORE_FILE_PREFIX, KEY_STORE_FILE_SUFFIX);
try (final FileOutputStream fos = new FileOutputStream(keyStoreFile.getPath())) {
final KeyStore ks = KeyStore.getInstance(KEY_STORE_TYPE, KEY_STORE_PROVIDER);
ks.load(null);
ks.setCertificateEntry("rootCaCertificate", rootX509Certificate);
ks.store(fos, DEFAULT_KEY_STORE_PASSWORD.toCharArray());
}
return keyStoreFile;
}
Here are the constants.
public static final String SSL_CERTIFICATE = "rds-ca-2019-root.pem";
public static final String KEY_STORE_TYPE = "JKS";
public static final String KEY_STORE_PROVIDER = "SUN";
public static final String KEY_STORE_FILE_PREFIX = "sys-connect-via-ssl-test-cacerts";
public static final String KEY_STORE_FILE_SUFFIX = ".jks";
public static final String DEFAULT_KEY_STORE_PASSWORD = "changeit";
Here is the link for rds-ca-2019-root.pem file place that file inder resources folder.
let me know this works for you.
Here is a sample
setSslProperties();
final MongoCredential credential = MongoCredential.createCredential(userName, mongoProps.getDatabaseName(), password.toCharArray());
final MongoClientSettings settings = MongoClientSettings.builder()
.credential(credential)
.readPreference(ReadPreference.secondaryPreferred())
.retryWrites(false)
.applyToSslSettings(builder -> builder.enabled(true))
.applyToConnectionPoolSettings(connPoolBuilder ->
ConnectionPoolSettings.builder().
maxSize(1).build())
.applyToClusterSettings(builder ->
builder.hosts(Arrays.asList(new ServerAddress(clusterEndPoint, 27017))))
.build();
mongoClient = MongoClients.create(settings);
As pointed out by #mmr25 in comments to #Barath answer, The solution only works for when service needs to only connect to documentDB. You start getting "Gettting PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested" for other http requests.
To address this issue we need to only enable sslcontext for documentdb connections. To do we can use Netty as HttpClient for mongodb connections. To enable netty we need to add following maven dependency to your spring boot project:
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-tcnative-boringssl-static</artifactId>
<version>2.0.53.Final</version>
</dependency>
and put your pem file in your resources folder and define following beans in one of the class annotated with #Configutation annotations.
#Slf4j
#Configuration
public class MongoDbConfiguration {
private static final String AWS_PUBLIC_KEY_NAME = "rds-ca-2019-root.pem";

.build();
ConnectionString connectionString = new ConnectionString(mongoConnectionUri);
return MongoClients.create(
MongoClientSettings.builder()
.applyConnectionString(connectionString)
.applyToSslSettings(builder -> {

.streamFactoryFactory(NettyStreamFactoryFactory.builder()

}
}

The Simple solution is you can remove the TLS (SSL) option in AWS, then you can remove the "ssl_ca_certs=rds-combined-ca-bundle.pem" from your connection string. But if the application required the SSL DB connectivity, then you can use the
