MATRIXX Installation and Upgrade
Installing MATRIXX
A cloud native MATRIXX installation consists of containers installed with the MATRIXX Helm chart in a multi-node Kubernetes cluster (or clusters), requiring MATRIXX images and MATRIXX Engine custom resource definitions and controllers.
Obtain and Host Images
Obtain the images, Helm chart, and utility scripts from MATRIXX, and host the images in an image repository so that they can be retrieved and instantiated as containers.

MATRIXX Release Notes
MATRIXX Architecture
MATRIXX Installation and Upgrade
- About MATRIXX Installation and Upgrade
  MATRIXX Installation and Upgrade describes the tasks required to install MATRIXX components as containers using Kubernetes and Helm.
- Cloud Native Infrastructure Requirements
  Cloud native MATRIXX deployments have infrastructure requirements for third-party software versions, Kubernetes pod characteristics, and container characteristics. Nodes running MATRIXX components have operating system, memory, networking, and storage requirements.
- Topology Operator and Engine Operator Feature Differences
  Different MATRIXX features are supported depending on whether your installation is based on Topology Operator or Engine Operator.
- Installing MATRIXX
  A cloud native MATRIXX installation consists of containers installed with the MATRIXX Helm chart in a multi-node Kubernetes cluster (or clusters), requiring MATRIXX images and MATRIXX Engine custom resource definitions and controllers.
  - Obtain and Host Images
    Obtain the images, Helm chart, and utility scripts from MATRIXX, and host the images in an image repository so that they can be retrieved and instantiated as containers.
  - Installing and Configuring Helm
    The Helm package manager 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.
  - Install the MATRIXX Charts in the Kubernetes Cluster
    After you install Helm and configure a private chart repository containing the MATRIXX charts, use Helm to install MATRIXX in the Kubernetes cluster.
  - Install in Multiple Namespaces
    Installing MATRIXX across multiple Kubernetes namespaces allows sub-groups of components to be upgraded without affecting the operation of other components.
  - Add or Remove a Domain in a Multi Domain Deployment
    When adding or removing domains, identify (or remove) the domain ID in the topology section of your Helm values file(s) and redeploy the common SBA Gateway CHF (for inbound traffic) and Traffic Routing Agent (TRA-RT/DR) instances for the deployment.
  - Engine Management
    Two different methods of MATRIXX Engine management are available: Topology Operator (default), and Engine Operator.
- Topology Operator Installation and Upgrade Examples
  These examples show how you can configure the installation of multiple MATRIXX Engines in a single namespace, multiple namespaces in a single cluster, and multiple clusters.
- Configuring MATRIXX
  MATRIXX is configured using Helm properties. Questions and answers in create_config.info files can also provide configuration using configuration sources. For information about how to configure MATRIXX, see the discussions of those topics in MATRIXX Configuration.
- Topology Operator
  The Topology Operator method of MATRIXX Engine pod management utilizes multiple custom resources (CRs) and operator pods working together to manage the installation and upgrade of multiple sub-domains and engines across Kubernetes clusters, including the loading of pricing and taxation data.
- Scaling MATRIXX
  Use Helm and Kubernetes to manually add or remove pods as necessary. You can also use Kubernetes to manage resources available to MATRIXX Engine pods.
- Network Enablers in a Kubernetes Cluster
  For Call Control Framework (CCF), only the deployment of Network Enablers (NEs) in a Kubernetes cluster is different from a standard deployment.
- Deploying Cloud Native CAMEL Gateway
  When deploying CAMEL Gateway as part of the reference architecture, you can use any namespace within the Kubernetes clusters. You can make multiple deployments into multiple namespaces, for example, to have different environments for testing and production.
- Enabling MEF Publishing
  An SSH key, used for password-less SSH login, is required to enable _glossary/mef.html 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.
- Encrypted Interface Engine Replay Overview
  Transport-layer security (TLS) encryption can be enabled for replay between processing and publishing pods and between engines.
- MATRIXX Reference for MongoDB
  Cloud native MATRIXX deployments support MongoDB as an event store using the MongoDB Enterprise Operator for Kubernetes.
- MATRIXX Reference for Apache Kafka
  The Event Streaming Framework provides a connector for sending event stream data to Apache Kafka. Using 5G event streaming also requires Apache Kafka, which is not provided with MATRIXX. You can use a Helm chart to install and configure Apache Kafka.
- MATRIXX Reference for Ingress
  A Kubernetes Ingress exposes HTTP and HTTPS routes from outside the cluster to services within the cluster.
- Debugging and Failure Recovery
  MATRIXX components store log files in persistent storage on the node by default, in a persistent volume (PV) at the location specified in global.storage.localStorageDir property (/home/data by default).
- Upgrading Engine Operator-Based MATRIXX Installations
  Upgrading cloud native MATRIXX has several stages.
- Migrating to Topology Operator
  This example shows migration from a MATRIXX version XXXX deployment managed by Engine Operator to a deployment managed by Topology Operator. The same approach applies when migrating from Engine Controller.
- Migration from a Bare Metal to a Cloud Native Deployment
  Migrating from a bare metal MATRIXX deployment to a cloud native deployment (from the same MATRIXX version) requires temporarily using a hybrid platform made up of components from both deployments. This hybrid environment allows migration to the cloud native deployment without disruption of services.
- The Admin Service
  Operations teams can use the Admin Service to administer a MATRIXX deployment with domain-specific commands based on the components that are installed. It allows administration of the installation without providing unrestricted direct access to the Kubernetes cluster. You can secure commands based on user roles and audit command usage.
- Uninstall MATRIXX Engine with Helm
  Use the helm uninstall command to uninstall MATRIXX Engine components installed from the Helm chart.

Glossary

Obtain and Host Images

Obtain the images, Helm chart, and utility scripts from MATRIXX, and host the images in an image repository so that they can be retrieved and instantiated as containers.

Procedure

Download manifest.txt, which contains a list of the available images.
Download each image listed in manifest.txt from the MATRIXX repository:
```
docker pull matrixx_repository/image:version
```

Use the docker tag command to define your repository:

docker tag matrixx_repository/image:version my_repository/image:version

Confirm the new image versions have been created correctly:
docker images
Push each image to your repository:
```
docker push my_repository/image:version
```
