IBM Containers running Spring Boot Applications with IBM Bluemix

There is now a new command line plugin for IBM containers on Bluemix so you can push and run docker images using CF CLI itself. The steps below show you how to set this up and I use a basic spring boot application as a docker image to test this out.

Steps

Take a note of the docker local host IP. In this example it was as follows, as I test my docker image on my laptop prior to pushing it to Bluemix.

-> docker is configured to use the default machine with IP 192.168.99.100

1. Install the latest CF command line, I used the following version.

pasapicella@pas-macbook-pro:~/bluemix_apps/CONTAINERS/ibm-containers/gs-rest-service/complete$ cf --version
cf version 6.14.0+2654a47-2015-11-18

https://github.com/cloudfoundry/cli

2. Install IBM Containers Cloud Foundry plug-in

pasapicella@pas-macbook-pro:~$ cf install-plugin https://static-ice.ng.bluemix.net/ibm-containers-mac

**Attention: Plugins are binaries written by potentially untrusted authors. Install and use plugins at your own risk.**

Note: Default plugin directory as follows

$HOME/.cf/plugins

3. Login to IBM Containers

pasapicella@pas-macbook-pro:~/bluemix_apps/CONTAINERS$ cf ic login

Authenticating with registry at host name registry.ng.bluemix.net
OK
Your container was authenticated with the IBM Containers registry.
Your private Bluemix repository is URL: registry.ng.bluemix.net/apples

You can choose from two ways to use the Docker CLI with IBM Containers:

Option 1: This option allows you to use "cf ic" for managing containers on IBM Containers while still using the Docker CLI directly to manage your local Docker host.
    Use this Cloud Foundry IBM Containers plug-in without affecting the local Docker environment:

    Example Usage:
    cf ic ps
    cf ic images

Option 2: Use the Docker CLI directly. In this shell, override the local Docker environment to connect to IBM Containers by setting these variables. Copy and paste the following commands:
    Note: Only Docker commands followed by (Docker) are supported with this option.

     export DOCKER_HOST=tcp://containers-api.ng.bluemix.net:8443
     export DOCKER_CERT_PATH=/Users/pasapicella/.ice/certs/containers-api.ng.bluemix.net/0bcbcada-bd11-4372-b416-955dff3078a1
     export DOCKER_TLS_VERIFY=1

    Example Usage:
    docker ps
    docker images4. View docker images

IBM Bluemix Secure Gateway Service with Oracle

I previously blogged about using the IBM Bluemix Secure Gateway Service as follows

http://theblasfrompas.blogspot.com.au/2015/11/ibm-bluemix-secure-gateway-service-step.html

I decided I would extend on this and Connect a Spring Boot Application to Oracle and consume Oracle data using the Secure Gateway Service.

The full demo is as follows

https://dl.dropboxusercontent.com/u/15829935/bluemix-docs/secure-gateway-oracle/index.html

IBM Bluemix Secure Gateway Service Step by Step Demo

I created this simple step by step guide on how to use the IBM Secure Gateway Service. Very simple demo which shows how easy it is to set this up and open a world of possibilities from on premise resources directly exposed via Bluemix whether it's PUBLIC or Dedicated/LOcal Instances

IBM Bluemix Admin Console Command Line (CLI) Installation

The IBM Bluemix Dedicated/Local Administration Console also includes support for CLI to enable common management tasks to be performed using the Cloud Foundry Command Line by adding a plugin to enable support for it's commands.

Note: The Bluemix Admin CLI plugin requires version 6.11.2 or later.

Admin Console UI

Admin Console - Installing Command Line

The CLI to the admin console is installed as follows. The reference to this is found in your own Dedicated/Local install via a link as follows with "cli" appended to the Admin Console URL

Spring Security Demo with a Bootstrap Look and Feel

I decided to take the Spring Security demo at the following link , and add Bootstrap to it. In the end it's basically the same code and the Form Based Login will accept one user "pas/welcome1".

http://spring.io/guides/gs/securing-web/

Here is the updated demo with Bootstrap added to the UI pages. You can deploy this to Bluemix using the "Deploy to Bluemix" directly from GitHub and it will as you to Sing into IBM devOps prior to deploying it directly into your Bluemix Environment.

IBM Bluemix - Spring Boot Elasticsearch Repositories demo

I decided to take the Elasticsearch repositories as part of the Spring Data project for a test drive. The Spring boot Elasticsearch repositories are described in the link below.

http://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.repositories

In this example I create a basic Spring Boot application using Elasticsearch, Web, Rest Repositories along with Thymeleaf / Bootstrap as the view pages. The code for this is on GitHub which also provides the "Deploy to Bluemix" button to deploy to your own instance of this application into your own Bluemix accout.

https://github.com/papicella/SpringBootElasticSearch

Like all Spring Data Repositories you can create an interface and be given basic CRUD operations to the Elastisearch DOCUMENT as shown below.

EmployeeRepository.java

 
package pas.au.ibm.bluemix.elastic;

import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;

import java.util.List;

public interface EmployeeRepository extends ElasticsearchRepository<Employee, String>
{
    public List<Employee> findByFirstNameContaining(String firstName);
} 

Employee.java

  
package pas.au.ibm.bluemix.elastic;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;

@Document(indexName = "employee", type = "employee", shards = 1, replicas = 0, refreshInterval = "-1")
public class Employee
{
    @Id
    private String id;
    private String firstName;
    private String lastName;
    private String job;
    private int deptNo;

    public Employee()
    {
    }

....

If you don't have a IBM DevOps Jazzhub account the manifest.yml can be used if you clone the project, and compile it using maven with "mvn package". Be sure to alter the application name / host to be a unique name within Bluemix.

IBM Bluemix - Specify only Liberty buildpack features you require

I am more often then not using spring boot applications on IBM Bluemix and most of what I need is packaged with the application from JPA or JDBC, drivers, Rest etc. Of course with IBM Bluemix we can specify which build pack we wish to use but by default for java applications LIberty is used.

When a stand-alone application is deployed, a default Liberty configuration is provided for the application. The default configuration enables the following Liberty features:

• beanValidation-1.1
• cdi-1.2
• ejbLite-3.2
• el-3.0
• jaxrs-2.0
• jdbc-4.1
• jndi-1.0
• jpa-2.1
• jsf-2.2
• jsonp-1.0
• jsp-2.3
• managedBeans-1.0
• servlet-3.1
• websocket-1.1
• icap:managementConnector-1.0
• appstate-1.0

Here is how I strip out some of what isn't required in my Liberty runtime container to a bare minimal of what I need.

manifest.yml

applications:
 - name: pas-speedtest
   memory: 512M
   instances: 1

IBM Bluemix - Triggerring backing service creation from "Deploy to Bluemix" button

I recently posted about the "Deploy to Bluemix" button which will automatically deploy an application into IBM Bluemix from a single click.

http://theblasfrompas.blogspot.com.au/2015/09/adding-deploy-to-bluemix-button-to-my.html

If the application requires backing services they can automatically be created using the"declared-services" tag as shown below. Declared services are a manifest extension, which creates or looks for the required or optional services that are expected to be set up before the app is deployed, such as a data cache service. You can find a list of the eligible Bluemix services, labels, and plans by using the CF Command Line Interface and running cf marketplace

manifest.yml

declared-services:
  redis-session:
    label: rediscloud
    plan: 30mb
applications:
 - name: pas-sbsessions
   memory: 512M
   instances: 2
   path: ./target/SpringBootHTTPSession-0.0.1-SNAPSHOT.jar
   host: pas-sbsessions
   domain: mybluemix.net
   buildpack: java_buildpack
   services:
    - redis-session

Note: Declared services is an IBM extension of the standard Cloud Foundry manifest format. This extension might be revised in a future release as the feature evolves and improves.

Adding the "Deploy to Bluemix" Button to my Bluemix Applications in GitHub

Not before time I finally added my first "Deploy to Bluemix" button on my GitHub projects for Bluemix applications. The screen shot below shows this for the Spring Session - Spring Boot Portable Cloud Ready HTTP Session demo.

Here is what it looks like when I do deploy this using the "Deploy to Bluemix" button and requires me to log in to IBM Bluemix. What happens when you use this button it adds the prohect code via FORK to your own DevOps projects , adds a pipeline to compile/deploy the code and finally deploys it as you Expect it to do.

Spring Session - Spring Boot application for IBM Bluemix

The following guide shows how to use Spring Session to transparently leverage Redis to back a web application’s HttpSession when using Spring Boot.

http://docs.spring.io/spring-session/docs/current/reference/html5/guides/boot.html

The demo below is a simple Spring Boot / Thymeleaf/ Bootstrap application to test Session replication using Spring Session - Spring Boot within IBM Bluemix. Same demo will run on Pivotal Cloud Foundry as well.

Integrating Telstra Public WIFI API into Bluemix

I previously blogged about Integrating Telstra Public SMS Api as shown below.

http://theblasfrompas.blogspot.co.nz/2015/08/integrating-telstra-public-sms-api-into.html

Here I show how I integrated Telstra Public WIFI Api into IBM Bluemix. This Api from Telstra is documented as follows. You need to register on http://t.dev to get the credentials to use thier API which I have previously done which then enables me to integrate it onto Bluemix

https://dev.telstra.com/content/wifi-api

Once again here is the Api Within the Bluemix Catalog, these screen shots show the Api has been added to the Bluemix Catalog which can then be consumed as a service.

Finally here is a Web based application using Bootstrap so it renders quite well on mobile devices as well which allows you to enter your Latitidue, Longitude and Radius to find Telstra WIFI Hotspots using the Telstra WIFI Api on IBM Bluemix

Integrating Telstra Public SMS API into Bluemix

In the post below I will show how I integrated Telstra public SMS Api into my Bluemix catalog to be consumed as a service. This was all done from Public Bluemix using the Cloud Integration Service.

Step 1 - Create a T.DEV account

In order to get started you need to create an account on http://dev.telstra.com in order to be granted access to the SMS API. Once access is granted you need to create an application which enables you to add/manage Telstra API keys as shown below.

1.1 Create an account an http://dev.telstra.com

1.2. Once done you should have something as follows which can take up to 24 hours to get approved as shown by the "approved" icon

Step 2 - Test the SMS Telstra API

At this point we want to test the Telstra SMS API using a script, this ensures it's working before we proceed to Integrating it onto Bluemix.

2.1. Create a script called setup.sh as follows

#Obtain these keys from the Telstra Developer Portal APP_KEY="yyyy-key" APP_SECRET="yyyy-secret" curl "https://api.telstra.com/v1/oauth/token?client_id=$APP_KEY&client_secret=$APP_SECRET&grant_type=client_credentials&scope=SMS"

2.2. Edit the script above to use your APP_KEY and APP_SECRET values from the Telstra Developer Portal

2.3. Run as shown below

pas@Pass-MBP:~/ibm/customers/telstra/telstra-apis/test$ ./setup.sh { "access_token": "xadMkPqSAE0VG6pSGEi6rHA5vqYi", "expires_in": "3599" }

2.4. Make a note of the token key returned, you will need this to send an SMS message
2.5. Create a script called "sendsms.sh" as shown below.

# * Recipient number should be in the format of "04xxxxxxxx" where x is a digit # * Authorization header value should be in the format of "Bearer xxx" where xxx is access token returned # from a previous GET https://api.telstra.com/v1/oauth/token request. RECIPIENT_NUMBER=0411151350 TOKEN=token-key curl -H "Content-Type: application/json" \ -H "Authorization: Bearer $TOKEN" \ -d "{\"to\":\"$RECIPIENT_NUMBER\", \"body\":\"Hello, pas sent this message from telstra SMS api!\"}" \ "https://api.telstra.com/v1/sms/messages"

2.6. Replace the token key with what was returned at step 2.4 above
2.7. Replace the RECIPIENT_NUMBER with your own mobile number to test the SMS API.
2.8. Run as shown below.

pas@Pass-MBP:~/ibm/customers/telstra/telstra-apis/test$ ./sendsms.sh {"messageId":"1370CAB677B59C226705337B95945CD6"}

Step 3 - Creating a REST based service to Call Telstra SMS API

At this point we can now Integrate the Telstra SMS API into Bluemix. To do that I created a simple Spring Boot Application which exposes a RESTful method to call Telstra SMS API using Spring's RestTemplate class. I do this as it's two calls you need to make to call the Telstra SMS API. A REST based call to get a ACCESS_TOKEN , then followed by a call to actually send an SMS message. Creating a Spring Boot application to achieve this allows me to wrap that into one single call making it easy to consume and add to the Bluemix Catalog as a Service.

More Information on The Cloud Integration service can be found here. Cloud Integration allows us to expose RESTful methods from Bluemix applications onto the catalog via one simple screen. We could alos use Bluemix API management service as well.

https://www.ng.bluemix.net/docs/services/CloudIntegration/index.html

Below shows the application being pushed into Bluemix which will then be used to add Telstra SMS API service into the Bluemix catalog.

Step 4 - Add the RESTful method to IBM Bluemix catalog to invoke the Telstra SMS API

4.1 To expose our RESTful method we simply define the end point using the Cloud Integration service as shown below.

The image showing the Cloud Integration service with the Telstra API exposed and available to be consumed as a Service on Bluemix.

This was created using the Bluemix Dashboard but can also be done using the Cloud Foundry command line "cf create-service ..."

Step 5 - Create a Application client which will invoke the Telstra SMS service

At this point we are going to push a client application onto Bluemix which consumes the Telstra SMS API service and then uses it within the application. WE do this to verify the service works creating a simple HTML based application which invokes the service which has a manifest.yml file indicating it wants to consume the service which is now exposed on the catalog within Bluemix as per above.

5.1. The manifest.yml consumes the service created from the API in the catalog

applications: - name: pas-telstrasmsapi-client   memory: 512M   instances: 1   host: pas-telstrasmsapi-client   domain: mybluemix.net   path: ./target/TelstraSMSApiClient-0.0.1-SNAPSHOT.jar   env:    JBP_CONFIG_IBMJDK: "version: 1.8.+"   services:     - TelstraSMS-service

5.2. Push the application as shown below.

Using JRE 1.8 for the Liberty Buildpack in Bluemix

The latest Liberty biuldpack update now adds the ability to switch to JRE 1.8 runtime. Given I am now switching to JDK 1.8 for all my projects this has come in very handy, and of course Spring Boot favors JDK 1.8 as well. The default is still JRE 1.7 so to switch to 1.8 set an ENV variable as follows in your manifest.yml as shown below.

manifest.yml

applications:
- name: pas-myapp
  memory: 512M
  instances: 1
  host: pas-myapp
  domain: mybluemix.net
  path: ./target/myapp-1.0-SNAPSHOT.jar
  env:
   JBP_CONFIG_IBMJDK: "version: 1.8.+"

Accessing your Cloud Integration API end point from Javascript

I previously created a Cloud Integration endpoint using a Bluemix Application Itself. The application was a Sprint Boot application exposing a single REST endpoint. The screen shots below show what has been added to the Catalog as private API's in my organization. The demo below shows how to access the API using a Javascript client in this case NodeJS from the command line.

Here is how we can access that API using a Javascript SDK which we can download from the Cloud Integration service itself.

1. Click on the "Cloud Integration" service itself
2. Select your API endpoint
3. Under "Access SDK's" select "Javascript SDK" and unzip it onto your file system

Note: We will use NodeJS to run this code

4. Install the required packages using the following command

> npm install

5. Ensure you import the API module as follows , as we are not using NPM for the API itself. The code is commented out so simply add it back in and change the reference to use "sdk"

// Alternatively, if you are not using npm, then import the API class module.
var sdk = require('./lib/SpringBootHelloWorldAPI.js');
console.log("Imported API class module ok");

6. The full code is as follows which enables us to display the function call output within the method itself. There are many ways to do this but just so we invoke it this is good enough.

  
// Import the SDK package.
//var sdk = require('SpringBootHelloWorldAPI');

// Alternatively, if you are not using npm, then import the API class module.
var sdk = require('./lib/SpringBootHelloWorldAPI.js');
console.log("Imported API class module ok");

// Create a new instance of the API class.
var api = new sdk.SpringBootHelloWorldAPI();

// Set the API credentials.
// TODO: replace username and password with those from the API definition.
//api.setAPICredentials('username', 'password'); // The API credentials are optional.

// Example for the HelloWorldService operation.
function example_HelloWorldService() {

 // Set up the request parameters for the HelloWorldService operation.
 var request = {};

        console.log("About to call service method");

 // Invoke the HelloWorldService operation.
 api.HelloWorldService(request, function (error, callback) {

  // Handle any errors from the HelloWorldService operation.
  if (error) {
   console.log(error);
   throw error;
  }

                func_result = callback;
                console.log(func_result);

 });

}

example_HelloWorldService();

7. Edit ./lib/SpringBootHelloWorldAPI.js and change the final line of JavaScript code to be as follows

module.exports.SpringBootHelloWorldAPI = SpringBootHelloWorldAPI;

8. Finally call the API using the Javascript client as follows
 
pas@Pass-MacBook-Pro:~/bluemix-apps/cloud-integration/client-api/springboot-hello/javascript$ node example.js
Imported API class module ok
About to call service method
{ id: 48, content: 'Hello, World!' }

Auto Scaling Service within Bluemix

I decided to test out the Auto Scale service in IBM Bluemix following this example which shows how to also use the Blazemeter service to Load test the application to simulate extra memory requirement on the application.

https://developer.ibm.com/bluemix/2015/04/03/handle-unexpected-bluemix-auto-scaling/

The demo is quite straight forward to setup and the screen shots below show what the service output gives in terms of auto scaling history and of course metric statistics for the selected policy configuration.
