Microservices using WildFly Swarm, Docker and Couchbase

June 27, 2016containers, couchbase, redhat, wildflycouchbase, docker, microservice, nosql, wildflyarungupta

Containers, Microsoervices, and NoSQL provide an awesome threesome for building your modern applications. These applications need to be agile, meet constantly evolving customer demands, be pervasive, and should work across mobile, web and IoT platforms.

This blog will explain a simple microservices stack using WildFly Swarm, Docker, and Couchbase. Complete code and instructions in this blog are documented at: github.com/arun-gupta/wildfly-swarm-couchbase.

Let’s understand the key components of this stack first!

WildFly Swarm allows to package and run JavaEE applications by packaging them with just enough of the server runtime to java -jar your application. With built-in service discovery, single sign-on using Keycloak, monitoring using Hawkular, and many more features, WildFly Swarm provides all the necessary components to develop your microservice.

docker-for-mac

Docker for Mac provides native support for running Docker containers on Mac OSX. It relies upon Hypervisor.framework in OSX. Docker engine runs in an Alpine Linux distribution on top of an xhyve Virtual Machine, and even the VM is managed by Docker. There is no need for Docker Machine or VirtualBox, and it integrates with OSX security sandbox model. DockerCon 2016 removed the private beta restriction from Docker for Mac, and so its available for everybody now.

NoSQL provides the agility and flexibility of schema-less databases. This allows the application to evolve independently and rapidly without going through cumbersome database migrations. Couchbase offers true horizontal scaling with homogenous architecture, as opposed to non-scalable master/slave architecture. It also offers auto-sharding, SQL-like query language for JSON (N1QL), mobile database and synchronization with the backend server, and much more.

The complete sample application in this blog is at: github.com/arun-gupta/wildfly-swarm-couchbase.

WildFly Swarm Application

Let’s look at the Java EE REST endpoint:

package com.couchbase.wildfly.swarm;

. . .

@Path("airline")
public class AirlineResource {

    @Inject Database database;
        
    @GET
    public String getAll() {
        N1qlQuery query = N1qlQuery.simple("SELECT * FROM `travel-sample` LIMIT 10");
        N1qlQueryResult result = database.getBucket().query(query);
        return result.allRows().toString();
    }
    
. . .
}

package com.couchbase.wildfly.swarm;

. . .

@Path("airline")

public class AirlineResource {

@Inject Database database;

@GET

public String getAll() {

N1qlQuery query = N1qlQuery.simple("SELECT * FROM `travel-sample` LIMIT 10");

N1qlQueryResult result = database.getBucket().query(query);

return result.allRows().toString();

}

. . .

}

It uses standard JAX-RS annotation to convert a POJO into a REST endpoint. Couchbase Java API provide a fluent API and used N1QL statement to query the documents and return the results. The N1QL statement returns the first 10 elements from the query result. Learn more about N1QL syntax in this interactive tutorial.

Database abstraction is defined as:

package com.couchbase.wildfly.swarm;

. . .

@Singleton
@Startup
public class Database {
    
    CouchbaseCluster cluster;
    Bucket bucket;
        
    public CouchbaseCluster getCluster() {
        if (null == cluster) {
            String couchbaseURI = System.getenv("COUCHBASE_URI");
            if (null == couchbaseURI) {
                System.err.println("WARING: No COUCHBASE_URI specified, defaulting to localhost");
                couchbaseURI = "localhost:8093";
            }
            System.out.println("Couchbase endpoint: " + System.getenv("COUCHBASE_URI"));
            cluster = CouchbaseCluster.create(couchbaseURI);
        }
        return cluster;
    }
    
    public Bucket getBucket() {
        if (null == bucket) {
            bucket = getCluster().openBucket("travel-sample");
        }
        return bucket;
    }
}

package com.couchbase.wildfly.swarm;

. . .

@Singleton

@Startup

public class Database {

CouchbaseCluster cluster;

Bucket bucket;

public CouchbaseCluster getCluster() {

if (null == cluster) {

String couchbaseURI = System.getenv("COUCHBASE_URI");

if (null == couchbaseURI) {

System.err.println("WARING: No COUCHBASE_URI specified, defaulting to localhost");

couchbaseURI = "localhost:8093";

}

System.out.println("Couchbase endpoint: " + System.getenv("COUCHBASE_URI"));

cluster = CouchbaseCluster.create(couchbaseURI);

}

return cluster;

}

public Bucket getBucket() {

if (null == bucket) {

bucket = getCluster().openBucket("travel-sample");

}

return bucket;

}

This is a singleton EJB that is eagerly initialized. It uses Couchbase Java SDK to connect to Couchbase. Database endpoint can be specified using the COUCHBASE_URI environment variable.

Next up is pom.xml for configuring the WildFly Swarm and Couchbase Java Client:

It uses WildFly Swarm “bill of materials” to pull in all the dependencies. Only the specific dependencies needed for the build are specified in <dependencies>. These are then packaged in the “fat jar”.

WildFly Swarm Maven plugin is used to package and run the application:

COUCHBASE_URI is used to read the host of where Couchbase database server is running.

Run Couchbase Server

Run the Couchbase server using Docker for Mac:

docker run -d --name db -p 8091-8093:8091-8093 -p 11210:11210 arungupta/couchbase

docker run -d --name db -p 8091-8093:8091-8093 -p 11210:11210 arungupta/couchbase

The arungupta/couchbase is built upon the standard Couchbase image and uses Couchbase REST API to configure the server.

Wait for a couple of minutes for the sample bucket to be populated with the JSON documents.

Invoke the Couchbase CLI tool cbq create a primary index on the sample bucket:

docker run -it --link db:db arungupta/couchbase cbq -u Administrator -p password -engine http://db:8093 -s "create primary index `travel-sample-primary-index` on `travel-sample`;"

docker run -it --link db:db arungupta/couchbase cbq -u Administrator -p password -engine http://db:8093 -s "create primary index `travel-sample-primary-index` on `travel-sample`;"

This will show the output as:

Connected to : http://db:8093/. Type Ctrl-D or \QUIT to exit.

 Path to history file for the shell : /root/.cbq_history 
{
    "requestID": "d0b2e4dd-b702-49e2-971c-a4c640ddb498",
    "signature": null,
    "results": [
    ],
    "status": "success",
    "metrics": {
        "elapsedTime": "3.154540272s",
        "executionTime": "3.154493281s",
        "resultCount": 0,
        "resultSize": 0
    }
}

Connected to : http://db:8093/. Type Ctrl-D or \QUIT to exit.

Path to history file for the shell : /root/.cbq_history

{

"requestID": "d0b2e4dd-b702-49e2-971c-a4c640ddb498",

"signature": null,

"results": [

"status": "success",

"metrics": {

"elapsedTime": "3.154540272s",

"executionTime": "3.154493281s",

"resultCount": 0,

"resultSize": 0

}

This output shows that result of creating index was successful.

One of the advantages of running Docker for Mac is that all the containers are accessible at localhost. This means Couchbase Web Console can be accessed at localhost:8091.

This screen ensures that Couchbase is configured correctly.

Run WildFly Swarm Microservice

Package and run the self-contained microservice as:

mvn wildfly-swarm:run

mvn wildfly-swarm:run

If Couchbase is running on a different host, then the command will change to:

mvn -DCOUCHBASE_URI=<IP> wildfly-swarm:run

mvn -DCOUCHBASE_URI=<IP> wildfly-swarm:run

It shows the output as:

So you built a simple microservice using WildFly Swarm accessing a Couchbase database running as a Docker container.

Now, ideally this WildFly Swarm service should be packaged as a Docker image and then that Docker image would serve as the service. A Maven profile with the name docker is already added to pom.xml but issue #3 is making that scenario fail.

Query JSON using SQL with Couchbase Query Workbench – Coffee on Couchbase

January 11, 2016couchbasecouchbase, json, n1ql, nosql, sqlarungupta

You’d like to query JSON document database using SQL-like syntax?

Couchbase has N1QL for you.

N1QL is a declarative query language that extends SQL for JSON. You can query data via native framework and language integration, a fluent API, or the JDBC/ODBC drivers.

N1QL enables you to query JSON documents without any limitations – sort, filter, transform, group, and combine data with a single query. That’s right. You can combine data from multiple documents with a JOIN. That flexible data model you were promised? This is it. You’re no longer limited to “single table” and “table per query” data models.

N1QL Tutorial is a great resource to learn the concepts of querying JSON documents using SQL-like syntax. Here are some examples:

SELECT children[0].fname AS cname
    FROM tutorial
       WHERE fname='Dave'

SELECT children[0].fname AS cname

FROM tutorial

WHERE fname='Dave'

SELECT fname, age, age/7 AS age_dog_years 
    FROM tutorial 
        WHERE fname = 'Dave'

SELECT fname, age, age/7 AS age_dog_years

FROM tutorial

WHERE fname = 'Dave'

SELECT relation, COUNT(*) AS count
    FROM tutorial
        GROUP BY relation
            HAVING COUNT(*) > 1

SELECT relation, COUNT(*) AS count

FROM tutorial

GROUP BY relation

HAVING COUNT(*) > 1

SELECT t.relation, COUNT(*) AS count, AVG(c.age) AS avg_age
    FROM tutorial t
    UNNEST t.children c
    WHERE c.age > 10
    GROUP BY t.relation
    HAVING COUNT(*) > 1
    ORDER BY avg_age DESC
    LIMIT 1 OFFSET 1

SELECT t.relation, COUNT(*) AS count, AVG(c.age) AS avg_age

FROM tutorial t

UNNEST t.children c

WHERE c.age > 10

GROUP BY t.relation

HAVING COUNT(*) > 1

ORDER BY avg_age DESC

LIMIT 1 OFFSET 1

SELECT
product.name, 
COUNT(reviews) AS reviewCount,
ROUND(AVG(reviews.rating),1) AS AvgRating,
category 
 FROM reviews AS reviews
JOIN product AS product 
 ON KEYS reviews.productId
UNNEST product.categories AS category
WHERE category = "Appliances"
GROUP BY category, product
ORDER BY AvgRating 
DESC LIMIT 3

SELECT

product.name,

COUNT(reviews) AS reviewCount,

ROUND(AVG(reviews.rating),1) AS AvgRating,

JBoss EAP 7 and NoSQL using Java EE and Docker

December 21, 2015containers, couchbase, javaee, jboss, redhatcouchbase, docker, javaee7, jboss, nosqlarungupta

JBoss EAP 7 Beta is now released, many congratulations to Red Hat and particularly to the WildFly team!

There are plenty of improvements coming in this release as documented in Release Notes. One of the major themes is Java EE 7 compliance.

JBoss EAP 7 and Java EE 7

IBM and Oracle already provide commercially supported Java EE 7-compliant Application Servers. And now Red Hat will be joining this party soon as well. Although WildFly has supported Java EE 7 for 2+ years but commercial support is a critical for open source to be adopted enterprise-wide. So this is good news!

You can learn all about different Java EE 7 APIs in the DZone Refcardz that I authored along with @alrubinger.

Java EE 7 Refcardz

There are plenty of “hello world” Java EE 7 Samples that should all run with JBoss EAP. Hopefully somebody will update the pom.xml and add a new profile.

Why NoSQL?

If you are building a traditional enterprise application then you might be fine using an RDBMS. There are plenty of advantages of using RDBMS but using a NoSQL database instead has a few advantages:

No need to have a pre-defined schema and that makes them a schema-less database. Addition of new properties to existing objects is easy and does not require ALTER TABLE. The unstructured data gives flexibility to change the format of data any time without downtime or reduced service levels. Also there are no joins happening on the server because there is no structure and thus no relation between them.
Scalability, agility and performance is more important than the entire set of functionality typically provided by an RDBMS. This set of databases provide eventual consistency and/or transactions restricted to single items but more focus on CRUD.
NoSQL are designed to scale-out (horizontal) instead of scale-up (vertical). This is important knowing that databases, and everything else as well, is moving into the cloud. RBDMS can scale-out using sharding but requires complex management and not for the faint of heart. Queries requiring JOINs across shards is extremely inefficient.
RDBMS have impedance mismatch between the database structure and the domain classes. An Object Relational Mapping, such as one provided by Java Persistence API or Hibernate is needed in such case.
NoSQL databases are designed for less management and simpler data models lead to lower administration cost as well.

So you are all excited about NoSQL now and want to learn more:

Why NoSQL?
Why do successful enterprises rely on NoSQL?
Top 10 Enterprise NoSQL Usecases

In short, there are four different types of NoSQL databases:

Document: Couchbase, Mongo, and others
Key/Value: Couchbase, Redis, and others
Graph: Neo4J, OrientDB, and others
Column: Cassandra and others

Java EE 7 provides Java Persistence API that does not provide any support for NoSQL. So how do you get started with NoSQL with JBoss EAP 7?

This blog will show how to query a Couchbase database using simple Java EE application deployed on JBoss EAP 7 Beta.

What is Couchbase?

Couchbase is an open-source, NoSQL, document database. It allows to access, index, and query JSON documents while taking advantage of integrated distributed caching for high performance data access.

Developers can write applications to Couchbase using different languages (Java, Go, .NET, Node, PHP, Python, C) multiple SDKs. This blog will show how you can easily create a CRUD application using Java SDK for Couchbase.

Run JBoss EAP 7

There are two ways to start JBoss EAP 7.

Download and Run

Download JBoss EAP 7 Beta and unzip.

Start the application server as:

Docker Run

In a containerized world, you just docker run to run your JBoss EAP. However, JBoss EAP image does not exist on Docker Hub and so the image needs to be explicitly built. You still need to explicitly download JBoss EAP and then use the following Dockerfile to build the image:

# Use latest jboss/base-jdk:8 image as the base
FROM jboss/base-jdk:8

# Set the JBOSS_VERSION env variable
ENV JBOSS_VERSION 7.0.0.Beta
ENV JBOSS_HOME /opt/jboss/jboss-eap-7.0/

COPY jboss-eap-$JBOSS_VERSION.zip $HOME

# Add the JBoss distribution to /opt, and make jboss the owner of the extracted zip content
# Make sure the distribution is available from a well-known place
RUN cd $HOME \
    && unzip jboss-eap-$JBOSS_VERSION.zip \
    && rm jboss-eap-$JBOSS_VERSION.zip

# Ensure signals are forwarded to the JVM process correctly for graceful shutdown
ENV LAUNCH_JBOSS_IN_BACKGROUND true

# Expose the ports we're interested in
EXPOSE 8080 9990

# Set the default command to run on boot
# This will boot JBoss EAP in the standalone mode and bind to all interface
CMD ["/opt/jboss/jboss-eap-7.0/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]

# Use latest jboss/base-jdk:8 image as the base

FROM jboss/base-jdk:8

# Set the JBOSS_VERSION env variable

ENV JBOSS_VERSION 7.0.0.Beta

ENV JBOSS_HOME /opt/jboss/jboss-eap-7.0/

COPY jboss-eap-$JBOSS_VERSION.zip $HOME

# Add the JBoss distribution to /opt, and make jboss the owner of the extracted zip content

# Make sure the distribution is available from a well-known place

RUN cd $HOME \

&& unzip jboss-eap-$JBOSS_VERSION.zip \

&& rm jboss-eap-$JBOSS_VERSION.zip

# Ensure signals are forwarded to the JVM process correctly for graceful shutdown

ENV LAUNCH_JBOSS_IN_BACKGROUND true

# Expose the ports we're interested in

EXPOSE 8080 9990

# Set the default command to run on boot

# This will boot JBoss EAP in the standalone mode and bind to all interface

CMD ["/opt/jboss/jboss-eap-7.0/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]

The image is built as:

docker build -t arungupta/jboss-eap:7-beta .

docker build -t arungupta/jboss-eap:7-beta .

And then you can run the JBoss EAP 7 container as:

docker run -it -p 8080:8080 arungupta/jboss-eap:7-beta

Notice, how application and management ports are bound to all network interfaces. This will simplify to deploy the application to this JBoss EAP instance later.

Stop the server as we will show an easier way to start it later.

Start Application Server and Database

The Java EE application will provide a HTTP CRUD interface over JSON documents stored in Couchbase. The application itself will be deployed on JBoss EAP 7 Beta. So it would require to start Couchbase and JBoss EAP.

Use the Docker Compose file from github.com/arun-gupta/docker-images/blob/master/jboss-eap7-nosql/docker-compose.yml to start Couchbase and JBoss EAP 7 container:

mycouchbase:
  container_name: "db"
  image: couchbase/server
  ports:
    - 8091:8091
    - 8092:8092 
    - 8093:8093 
    - 11210:11210
jboss:
  image: arungupta/jboss-eap:7-beta
  environment:
    - COUCHBASE_URI=db
  ports:
    - 8080:8080
    - 9990:9990

mycouchbase:

jboss:

image: arungupta/jboss-eap:7-beta

environment:

- COUCHBASE_URI=db

ports:

- 8080:8080

- 9990:9990

The application is started as:

docker-compose --x-networking up -d

Configure Couchbase Server

Clone couchbase-javaee application. This Java EE application uses Couchbase Java SDK APIs to connect to the Couchbase server. The bootstrap code is:

CouchbaseCluster.create(System.getenv("COUCHBASE_URI"));

CouchbaseCluster.create(System.getenv("COUCHBASE_URI"));

and is invoked from Database abstraction.

Couchbase Server can be configured using REST API. These REST APIs are defined in a Maven profile in pom.xml of this application. And so configure Couchbase server as:

mvn install -Pcouchbase -Ddocker.host=$(docker-machine ip couchbase)

Why Couchbase over MongoDB? #SayNoToMongoDB

October 21, 2015couchbasecouchbase, mongodb, nosqlarungupta

MongoDB is one of the most popular NoSQL databases. Its easy to start, has good documentation, works well with a few nodes. But it starts to fall apart as the number of users increase or more nodes are added.

Do you keep struggling with MongoDB? Thought about Couchbase over MongoDB? But don’t know where to start.

Why are companies switching from MongoDB to Couchbase?

MongoDB is hard to scale from a single replica set to a fully sharded environment
MongoDB’s performance rapidly degrades with increasing users
MongoDB is significantly susceptible to data loss under failure
MongoDB requires a third-party cache to help it perform
When deployed in multiple geographies, MongoDB can’t perform all writes locally
MongoDB lacks a mobile solution
MongoDB is time-consuming to manage and maintain

Read how Couchbase avoids all of these problems in Struggling With MongoDB.

Couchbase vs MongoDB Architectural Differences and Their Impact whitepaper provide more details.

Talk to a Couchbase Solutions Engineer and learn if/how Couchbase can yield better results for your non-performing MongoDB.

Viber replaced MongoDB with 50% fewer Couchbase servers. AT&T, Comcast, eBay, GE, LinkedIn, Marriott, PayPal, Tesco, Verizon, VISA, Wells Fargo and many other customers are using Couchbase.

You can too! Why wait?

Getting Started with Couchbase using Docker

October 12, 2015containers, couchbase, techtipcouchbase, docker, nosqlarungupta

Couchbase Server 4.0 was recently released and can be downloaded and easily installed. Getting Started with Couchbase explains in very simple and easy steps on how to get started with Couchbase. But when living in a container world, everything is a Docker image. And Couchbase also has a Docker image.

This blog will explain how you can easily start a Couchbase Server 4.0 as a Docker image.

Install and Configure Docker

Docker is natively supported on Linux. So apt get docker-engine on Ubuntu or yum install docker-engine on CentOS will get you ready to use Docker.

On Mac or Windows, this is achieved by install Docker Machine. Docker Machine to Setup Docker Host explain in detail on how to install and configure Docker Machine.

Here is a brief summary to get you started with Docker:

Download Docker client:

> curl -L https://get.docker.com/builds/Darwin/x86_64/docker-1.8.3 > /usr/local/bin/docker
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

> chmod +x /usr/local/bin/docker-machine

Create Docker Machine host:

> docker-machine create --driver=virtualbox default
Creating VirtualBox VM...
Creating SSH key...
Starting VirtualBox VM...
Starting VM...
To see how to connect Docker to this machine, run: docker-machine env default

> docker-machine create --driver=virtualbox default

Creating VirtualBox VM...

Creating SSH key...

Starting VirtualBox VM...

Starting VM...

To see how to connect Docker to this machine, run: docker-machine env default

Setup Docker client to connect to this host:

> eval $(docker-machine env default)

> eval $(docker-machine env default)

Now your current shell is configured where the Docker client can run containers on the Docker Machine.

Run Couchbase Docker Container

Starting a Docker container on this machine is pretty straight forward. The CLI downloads the image from Docker Hub and then runs it on the Machine:

> docker run -d -p 8091:8091 couchbase

In this CLI, run command runs the container using the image id specified as the last argument, -p publish port 8091 from the container to 8091 on the Docker Machine, -d runs the container in background and prints the container id.

Watch the container status as:

> docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                                                           NAMES

Find out IP address of the Docker Machine:

> docker-machine ip default
192.168.99.100

> docker-machine ip default

192.168.99.100

Access the setup console at 192.168.99.100:8091, make sure to specify the exact IP address in your case. This will show the screen:

Configure Couchbase Server

First run of Couchbase Server requires you to configure it, lets do that next!

Click on the Setup button. Scroll to bottom of the screen, change the Data RAM Quota to 500 (MB-16530), and click on Next.
In Couchbase, data is stored in buckets. The server comes pre-installed with some sample buckets. Select the travel-sample bucket to install it and click on Next.
Configure the bucket by taking defaults:

Click on Next.
Enter personal details, agree to T&C, click on Next:
Provide administrator credentials:
Click on Next to complete the installation. This brings up Couchbase Web Console:

It takes a few seconds for the travel-sample bucket to be fully loaded. And once that is done, your Couchbase server is ready to roll!

Hibernate OGM: NoSQL solutions for Java EE (Hanginar #4)

January 13, 2015jboss, redhathanginar, hibernate, javaee, nosqlarungupta

Hibernate OGM brings the power and simplicity of JPA for NoSQL datastores.

It provides one standard way to access a variety of NoSQL datastores such as Infinispan, Ehcache, MongoDB, Neo4J. And support for others is coming. It even allows rich querying capabilities and convert them into datastore-specific query (if supported). You can even mix/match Persistence Unit in persistence.xml for a RBDMS and NoSQL datastore.

This hanginar (#1, #2, #3) with Emmanuel Bernard (@emmanuelbernard) shows how to get started with Hibernate OGM. It specifically addresses the following questions:

What NoSQL datastores are supported?
Can I build support for other datastores?
What application servers can it run on?
Do I need Hibernate for it, or does it work with EclipseLink?
Can I have a SQL and NoSQL PU in persistence.xml and access them from Java EE application?
Can I use this in Java SE applications?

Learn everything about Hibernate OGM at hibernate.org/ogm/.

Source code used in the webinar is at github.com/hibernate/hibernate-demos/tree/hanginar-201501.

Enjoy!
