Set up Magnolia PaaS

This page guides you on setting up everything you need to set up a new Magnolia PaaS project.

Check you have the correct prerequisites, create your project, and then get ready to deploy your Magnolia PaaS project.

Prerequisites

There are a few things that you need before you can get started with developing for your Magnolia PaaS project.

Java

Currently, the minimum supported Java version for Magnolia PaaS is Java 11 (LTS).

Magnolia needs at least a Java Runtime Environment (JRE) to run. Check if there’s a version of Java already installed on your computer by opening the terminal or command prompt and typing java -version. If the system reports a version number, Java is installed on your computer.

See Certified stack page to confirm that the version installed is supported.

Maven

Download and Install Maven 3. Follow the OS-specific installation instructions from the Maven website (e.g. setting PATH environment variable).

In order to verify Maven has been installed correctly:

Open a terminal or a shell and run:

`mvn -v`
Maven keeps your user configuration and local repository under th ${user.home}/.m2/ directory.

Setting up credentials

To encrypt your Nexus credentials, execute the following command in your terminal or shell

mkdir -p ~/.m2 ; read -s -p 'Please enter your master Maven password: ' MASTPASS && \
echo "<settingsSecurity><master>`mvn --encrypt-master-password $MASTPASS`</master></settingsSecurity>" > ~/.m2/settings-security.xml ; \
unset MASTPASS

After you have set up Password Encryption above, switch to your shell and run the following command:

mvn org.sonatype.plugins:nexus-m2settings-maven-plugin:1.6.5:download -DnexusUrl=link:https://nexus.magnolia-cms.com -DtemplateId=magnolia-enterprise

Testing Maven settings

A simple way to test your settings: Try to build a project with Maven which is dependent on a Magnolia Enterprise module. Try to build a DX Core bundle from the Magnolia official Maven archetypes:

mvn archetype:generate -Dfilter=info.magnolia.maven.archetypes:magnolia

Mirroring

If you have your own Repository Manager, the following are the repositories you can mirror:

  1. You need a Magnolia account to access these repositories. For mirroring, please get a "robots" account with us.

  2. There are a few third-party artifacts that we have customized and released ourselves. We usually move back to regular releases when fixes are publicly released in these.

  3. A few artifacts Magnolia uses which are not available in the Maven Central Repository.

IDE

Make sure you have a Java IDE installed. It could be:

Create a project using the Maven archetype

Create a custom cloud bundle from the following Maven Archetypes:

mvn archetype:generate \
    -DarchetypeGroupId=info.magnolia.maven.archetypes \
    -DarchetypeArtifactId=magnolia-dx-core-custom-cloud-archetype \
    -DarchetypeVersion=1.8 \
    -DarchetypeRepository=https://nexus.magnolia-cms.com/content/repositories/magnolia.public.releases

You will be prompted to enter the following info:

  • groupId: The Maven groupId of your cloud bundle (ie: info.magnolia.demo)

  • artifactId: The Maven artifactId of your cloud bundle (ie: magnolia-demo-ecommerce)

  • version: The Maven version of your cloud bundle (ie: 1.0-SNAPSHOT). The final version is generated on release.

  • package: The Maven base package of your cloud bundle (usually same a the groupId)

  • magnolia-bundle-version: The Magnolia version to be used in your cloud bundle (ie: 6.2.42)

  • project-name: The project name (ie: magnolia-demo-ecommerce)

  • shortname: The name of the project to be used in the Magnolia URLs (ie: https://dev.shortname.magnolia-platform.com/author)

  • region: The AWS region the database backup bucket is located in (ie: eu-central-1)

The command will then create the Magnolia Java Webapp project.

The Java webapp in Magnolia PaaS has a typical structure.

Webapp structure example
custom
├── .gitignore
├── .gitlab-ci.yml (1)
├── .m2
│   └── settings.xml
├── README.md
├── custom-webapp
│   ├── Dockerfile
│   ├── pom.xml
│   ├── src
│   └── target
├── pom.xml
└── values.yml (2)
1 The .gitlab-ci.yml file ensures your development changes are automatically picked up.
2 The values.yml file ensures your Magnolia PaaS application is deployed to the your cluster.

On the first level you will find the pom.xml file which automatically contains the magnolia-dx-core-custom-cloud-parent artifact.

Testing the project

Open a terminal and go to the newly created project and then execute the following Maven build command:

mvn clean package

Starting Magnolia locally

Load the project in your IDE and configure the Tomcat server with the following system variables.

-Xms1024m
-Xmx2048m
-Dmagnolia.develop=true
-Dmagnolia.superuser.enabled=true
-Dmagnolia.utf8.enabled=true
-Dmagnolia.update.auto=true
-Dmagnolia.resources.dir="/opt/magnolia/light-modules"
-Dmagnolia.repositories.home="/opt/magnolia/repositories"
-Dmagnolia.webapp="Goofy Author"
-Dmagnolia.inject.config="createPath:/modules/enterprise/license\;setProperty:/modules/enterprise/license,owner,
your_email\;setProperty:/modules/enterprise/license,key,your_license_hash“

Custom cloud parent project

The custom cloud parent project automatically excludes the following modules:

It includes the following modules:

  • Instrumentation: Exposes the Magnolia metrics to the monitoring service.

  • Configuration injection: Facilitates the customization of Magnolia.
