MATRIXX Cloud Native Installation and Configuration
Enabling MEF Publishing in Kubernetes
An SSH key, used for password-less SSH login, is required to enable MATRIXX Event File (MEF) publishing in Kubernetes. A secret holds the SSH private key, and the key is specified in Helm values. The SSH key allows administrators to write to a target directory in a secure manner without having to enter a passphrase.

Architecture Overview
MATRIXX Cloud Native Installation and Configuration
- About MATRIXX Cloud Native Installation and Upgrade
  MATRIXX Cloud Native Installation and Upgrade describes the tasks required to install MATRIXX Digital Commerce components as containers, using Docker and Kubernetes.
- MATRIXX Docker Images and Supporting Files
  The MATRIXX Digital Commerce software for Docker and Kubernetes is delivered in Docker images. The Helm chart and base configuration files are delivered in TAR archives.
- Installing MATRIXX Digital Commerce
  A containerized MATRIXX Digital Commerce deployment consists of containers running in pods in a multi-node Kubernetes cluster, requiring MATRIXX Digital Commerce Docker images and MATRIXX Engine and Traffic Routing Agent custom resource definitions and controllers.
- Obtain and Host Docker Images
  Obtain the Docker images, utility scripts, and YAML manifest files from MATRIXX, and host the Docker images in a registry so that they can be retrieved and instantiated as containers by Kubernetes.
- Installing and Configuring Helm
  Helm provides a mechanism for deploying Kubernetes manifest files in a controlled manner, and facilitates application upgrade, scaling, and where necessary, rollback. To use the MATRIXX Helm chart, install the Helm software, create a chart repository, and load the MATRIXX Helm chart and sub-charts into your repository.
- Required Helm Role Access Permissions
  The user account that deploys MATRIXX Digital Commerce has specific Helm role requirements.
- Installing MATRIXX Digital Commerce in the Kubernetes Cluster
  Installing cloud native MATRIXX Digital Commerce involves adjusting and rebuilding the MATRIXX Engine sideloader Docker image, then installing with Helm.
- Configuring MATRIXX Digital Commerce Using Helm
  Configure MATRIXX Digital Commerce by adding values for properties from the MATRIXX Helm chart to the values.yaml file. The MATRIXX Helm chart includes component sub-charts in a hierarchy of reusable components.
- Using the MATRIXX Helm Chart
  MATRIXX Digital Commerce is delivered as multiple Docker images that can be deployed in different configurations.
- MATRIXX Cloud Native Reference Architecture
  A MATRIXX Digital Commerce reference configuration runs in Kubernetes clusters in a private or public cloud.
- EKS Reference Architecture
- Enabling MEF Publishing in Kubernetes
  An SSH key, used for password-less SSH login, is required to enable MATRIXX Event File (MEF) publishing in Kubernetes. A secret holds the SSH private key, and the key is specified in Helm values. The SSH key allows administrators to write to a target directory in a secure manner without having to enter a passphrase.
  - Enable MEF Publication in Kubernetes
    Enable MEF publication in Kubernetes by answering the MEF publication-related questions when running the create_config.py script to enable the publishing blade to generate MEFs in Kubernetes. For more information about MEF publishing, see the discussion about MEF automatic publishing in MATRIXX Engine Integration.
  - Configure MEF Publishing in Kubernetes
    Follow this procedure to configure MEF publishing in Kubernetes.
- Debugging and Failure Recovery
  The MATRIXX Engine controller and MATRIXX Engine manager pods create, configure, and start the MATRIXX Engine(s) in a deployment.
- Obtain Version Information from Kubernetes
  You can obtain version and build information for the MATRIXX Engine, while running, with Kubernetes commands.
- Upgrading Kubernetes
  Upgrade Kubernetes by upgrading the cluster where the standby MATRIXX Engine, is running, and then upgrading the cluster where the active MATRIXX Engine is running.
- Upgrading Cloud Native MATRIXX Digital Commerce
  Upgrading or reconfiguring a Cloud Native MATRIXX Digital Commerce installation involves obtaining and hosting the Docker images and Helm charts, preparing configuration, generating new pricing information, and finally upgrading the deployment.
- Control Scripts for Containerized Installations
- Uninstall MATRIXX Engine with Helm
  Use the helm uninstall command to uninstall MATRIXX Engine components installed from the Helm chart.

Enabling MEF Publishing in Kubernetes

An SSH key, used for password-less SSH login, is required to enable MATRIXX Event File (MEF) publishing in Kubernetes. A secret holds the SSH private key, and the key is specified in Helm values. The SSH key allows administrators to write to a target directory in a secure manner without having to enter a passphrase.

Important: Configure MEF publishing, configure the Helm charts, and enable MEF publishing in Kubernetes before deployment.

The Kubernetes secret stores the SSH private key in id_rsa and the known_hosts file so that the private key can be copied into the publishing pod. If either id_rsa or known_hosts is missing when configuring the Helm charts, MEF publishing will fail.

Important: For security purposes, periodically rotate SSH keys.
