Mulesoft with Java Plugin

Mulesoft is an integration platform that helps different businesses connect their data, devices, and applications for both cloud computing and on-premise deployments. Mulesoft's Anypoint Platform™ is a solution for API-led connectivity that creates an application network of apps, data, and devices for both on-premise and cloud deployments. Traceable provides a Java policy that can help you in protecting your APIs. You can attach the Traceable policy to any API registered on the Anypoint platform for security and monitoring purposes. The following diagram shows the high-level deployment of Traceable policy in your environment. 

Before you begin

Before proceeding to attach Traceable policy to an API on your Mulesoft Anypoint Platform, make a note of the following points:

• Maven (mvn) must be installed.
  Note:

  Maven 3.9 has compatibility issues with the Mule plugin, we recommend using Maven 3.8 or earlier.
• Java 8 must be installed.
• You should have access and permission to upload artifacts to Mulesoft exchange in your organization's Mulesoft Anypoint Platform account.
  Note

  To upload Traceable's custom policy to Mulesoft Exchange, you must have the exchange contributor's role assigned to you. For more information, see Uploading a Custom Policy to Exchange.
• Keep the IP address of your Traceable agent handy. You would need this IP address to configure the Traceable's Mulesoft policy.

The process to attach Traceable's policy consists of two steps:

1. Download the policy from Traceable's download site and then upload to Mulesoft's Exchange
2. Attaching the policy to the API in Mulesoft.

Step 1 — Download the Java policy and upload to Mulesoft Exchange

Complete the following steps to download and unzip Traceable's Java policy:

1. Navigate to Traceable's download site and then navigate to agent > mulesoft-java-plugin > latest.
2. Unzip the downloaded file.
3. Change directory to Mulesoft policy directory.
   ActionScriptActionScript

   cd traceable-mule-policy

4. Install the Traceable extension to your local Maven. Enter the following command:
   ActionScriptActionScript

   mvn install:install-file -Dfile=$(ls | grep traceable-mule-extension) -DgroupId=ai.traceable.agent -DartifactId=traceable-mule-extension -Dversion=1.0.0 -Dclassifier=mule-plugin -Dpackaging=jar -DgeneratePom=true

5. Navigate to Traceable policy.
   ActionScriptActionScript

   cd traceable-java

6. Update the groupId in pom.xml file to your Mulesoft organization's ID.
   ActionScriptActionScript

   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
       <modelVersion>4.0.0</modelVersion>
   
   <!--UPDATE GROUP ID-->
       <groupId>4c2d42c8-910d-42fe-8f21-bc76f21ef3fe</groupId>
       <artifactId>traceable</artifactId>
       <version>1.15.0</version>

Policy deployment options

You have two options to deploy Traceable policy.  You can either use mvn or curl command to deploy the policy.

Option 1 - Deploy using mvn

Make a note of the following before proceeding with this option. For more information on mvn install, see Mulesoft documentation, Uploading a Custom Policy to Exchange.

• Traceable's Mulesoft agent earlier than 1.21.0 - If you are using Traceable's Mulesoft agent earlier than 1.21.0, then in your Maven installation directory, update the settings.xml file with your Exchange credentials. 
  ActionScriptActionScript

  <?xml version="1.0" encoding="UTF-8"?>
  <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

         <username>myusername</username>
         <password>mypassword</password>
      </server>
    </servers>
  </settings>

• Traceable's Mulesoft agent 1.21.0 and later - If you are using Traceable agent 1.21.0 or later, then in your Maven installation directory, update the settings.xml file with your Exchange credentials.
  ActionScriptActionScript

  ActionScript
  <?xml version="1.0" encoding="UTF-8"?>
  <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <servers>
      <server>
         <id>anypoint-exchange-v3</id>
         <username>myusername</username>
         <password>mypassword</password>
       </server>
    </servers>
  </settings>

myusername and mypassword are your username and password to log in to Mulesoft account.

Deploy the Traceable policy. Enter the following command:

mvn clean deploy

Verify in your Mulesoft Anypoint Platform Exchange whether Traceable policy is present or not.

Option 2 - Deploy using curl command

To deploy using curl command, you would need a bearer token. You can use your bearer token or use Connected App credentials. Enter the following commands to deploy:

1. Build the Traceable policy. Enter the following command:
   ActionScriptActionScript

   mvn clean install

2. Publish the policy by running the following. Make sure to enter all the values in the <> brackets. The traceable_versionis the version of Traceable's Mulesoft policy.
   ActionScriptActionScript

   curl -v \
     -H 'Authorization: bearer ' \
     -H 'x-sync-publication: true' \
     -F 'files.pom=@/path/to/traceable-mule-policy/traceable/pom.xml' \
     -F 'files.mule-policy.jar=@/path/to/traceable-mule-policy/traceable/target/traceable--mule-policy.jar' \
     -F 'files.policy-definition.yaml=@/path/to/traceable-mule-policy/traceable/traceable.yaml' \
     -F 'files.docs.zip=@docs.zip' \
   https://anypoint.mulesoft.com/exchange/api/v2/organizations/<org_id>/assets/<org_id>/traceable/<traceable_version>

3. Verify in your Mulesoft Anypoint Platform Exchange whether Traceable policy is present or not.

Step 2 – Install Mulesoft agent as a policy

Complete the following steps:

1. Login to your Anypoint Platform and navigate to API Manager.
2. Select the API to which you wish to apply the Traceable policy.
3. Navigate to the Policies menu and click on Add Policy.
4. Search and select the Traceable policy and click on Next.
5. Configure the various options and click on Apply.

Configure TLS (optional)

You can optionally configure TLS for communication between Mulesoft and Traceable's Platform agent. To configure TLS, complete the following steps:

1. Create a truststore with trust anchor certificate used for creating the certificates for Traceable Platform agent. Enter the following command:
   ActionScript

   keytool -import -alias serverkey -keystore <truststore_name> -file <trust_anchor_cert_name> -storetype JKS

   Here is a breakdown of each command argument:

   • "keytool" refers to the Java keytool program that is used for managing public and private keys, digital certificates, and keystores.
   • "-import" is a command that specifies that you want to import a certificate.
   •  "-alias" is used to specify a name for the certificate being imported.
   • "serverkey" is the name given to the imported certificate.
   • "-keystore" is used to specify the name and location of the truststore file where the certificate should be imported.
   •  "<truststore_name>" is the name of the truststore file where the certificate should be imported. Replace this with the actual filename and path.
   •  "-file" is used to specify the name and location of the trust anchor certificate file that should be imported.
   •  "<trust_anchor_cert_name>" is the name of the trust anchor certificate file that should be imported. Replace this with the actual filename and path.
   • Overall, this command imports a certificate with the name "serverkey" into the truststore with the specified name and location, using a trust anchor certificate with the specified name and location.

     For example,

     ActionScriptActionScript

     keytool -import -alias serverkey -keystore client_truststore.jks -file root_ca.crt -storetype JKS

     Note

     If you already have a truststore, make sure that it is in the jks format.
2. Navigate to the policy directory. Enter the following command:
   ActionScript

   cd traceable-mule-policy/traceable-java/src/main

3. Copy your truststore into resources/truststore directory.
4. Navigate to the policy template. Enter the following command:
   ActionScript

   cd mule

5. In template.xml file, find the following line and change dummy_truststore.jks with the name of your truststore and dummyPassword with the password set while creating the truststore.
   ActionScriptActionScript

   <tls:trust-store/>

   and change it into the following format:

   <tls:trust-store path="truststore/<truststore_name>" password="<truststore_password>" type="jks"/>

   dummy_truststore.jks is the name of the truststore and dummyPasswordis the password set while creating the truststore.

6. Navigate back to project's root directory (traceable-mule-policy) and deploy the policy.

Configuration options

The following table describes the various configuration options.

Verification

To verify whether the policy successfully attached to the API in Mulesoft, navigate to Traceable platform. Click on Administration > Data Collection > Tracing agents. Check if Mulesoft agent is displayed and the status is active. You can further check for spans in API Analytics or API Activity under API Catalog.

Upgrade and uninstall

To upgrade the policy, follow the steps in mentioned in Step -1 section to add the new policy to Mulesoft's Exchange. After you have added the new policy to Mulesoft Exchange, complete the following steps:

1. Navigate to the API for which you want to upgrade the policy.
2. Click on the Policies option.
3. Click on the menu item as shown below. 
4. Click on Check for updates to update the policy.

If you wish to uninstall the policy, click on Remove policy.

Enable debug logs

You can enable debug logs by completing the following steps:

1. In Runtime Manager in your Anypoint Platform, navigate to the application for which you wish the logs to be enabled.
2. Navigate to the logging tab.
3. Add a new entry with the level set to debug and org.traceable.ai.internal and org.traceable.ai.impl package name.
