Learn how to deploy Dispatcher configuration files using Cloud Manager

Deploy Dispatcher configurations with Cloud Manager deploying-dispatcher-configurations

Cloud Manager can deploy web server and Dispatcher configuration files if they are stored in the Git repository with standard AEM content packages.

To use this capability, the Maven build produces a .zip file, which contains at least two directories: conf and conf.d. This .zip file can be produced using the maven-assembly-plugin.

Projects generated by Cloud Manager using the built-in project creation wizard have the correct Maven project structure created automatically. This approach is recommended if you are new to Adobe Managed Services (AMS).

When you deploy to a Dispatcher instance, the directories on the instance are replaced with those directories from your Git repository. To set the appropriate environment variables in /etc/sysconfig/httpd correctly, collaborate with your Customer Success team because web server and Dispatcher configuration files often require environment-specific details.

Dispatcher configuration for existing managed service customers steps-for-configuring-dispatcher

To complete the initial Dispatcher configuration, do the following:

  1. Obtain the current production configuration files from your Customer Success team.
  2. Remove environment-specific data, such as publish renderer IPs, and replace it with variables.
  3. Define required variables in key-value pairs for each target Dispatcher and add them to the variables folder on each instance.
  4. Test the updated configurations on your staging environment.
  5. Once tested, request your Customer Success team to deploy to production.
  6. Commit the files to your Git repository.
  7. Deploy through Cloud Manager.
NOTE
Migrating Dispatcher and web server configurations to your Git repository is done during Cloud Manager onboarding, but can also be done later.

Example example

The specific file and directory structure varies based on the specifics of your project, but this example provides a clear explanation of how to structure your project to include Apache and Dispatcher configurations.

  1. Create a subdirectory named dispatcher.

    Use any name here, but the directory name created in this step must be the same as the name used in step 1.

  2. This subdirectory contains a Maven module that builds the Dispatcher .zip file using the maven-assembly-plugin. In the dispatcher directory, create a pom.xml file with this content, changing the parent reference, artifactId, and name as necessary.

                                </descriptors>

                    </executions>
                </plugin>
            </plugins>
        </build>
    </project>
    
    • As in Step 1, the artifactId and name can be other values. dispatcher is used here as an example.
  3. The maven-assembly-plugin requires a descriptor to define how the .zip file is created. To create this descriptor, create a file in the dispatcher subdirectory named assembly.xml with the following content. Note that this file name is referenced on line 26 in the pom.xml file above.

    code language-xml
    <assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0 http://maven.apache.org/xsd/assembly-2.0.0.xsd">
      <id>distribution</id>
      <formats>
        <format>zip</format>
      </formats>
      <includeBaseDirectory>false</includeBaseDirectory>
      <fileSets>
        <fileSet>
          <directory>${basedir}/src</directory>
          <includes>
            <include>**/*</include>
          </includes>
          <outputDirectory></outputDirectory>
        </fileSet>
      </fileSets>
    </assembly>
    
  4. Create a subdirectory named src (as referenced in the assembly descriptor above on line 11) inside the Dispatcher subdirectory to store the actual Apache and Dispatcher configurations. Within this src directory, create directories named conf, conf.d, conf.dispatcher.d, and conf.modules.d.

  5. Populate the conf, conf.d, conf.dispatcher.d, and conf.modules.d directories with your configuration files. For example, the default configuration consists of these files and symbolic links.

  6. Finally, in the pom.xml file at your project’s root, add a <module> element to include the Dispatcher module.

    For example, if your existing module list is the following:

    code language-xml
        <modules>
            <module>core</module>
            <module>ui.apps</module>
            <module>ui.content</module>
        </modules>
    

    Change it to the following:

    code language-xml
        <modules>
            <module>core</module>
            <module>ui.apps</module>
            <module>ui.content</module>
            <module>dispatcher</module>
        </modules>
    
    • As noted in step 1, the value of the <module> element must match the directory name created.
  7. To test, run mvn clean package in the project root directory. You see lines like this in the output.

    code language-none

    You can also unzip this file to view its contents.
