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.
- 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.
  - Network Enabler Deployment Architecture
    Network Enablers (NEs) run inside their own Kubernetes pods, one pod per NE. A number of Kubernetes services are defined to allow connection to and from the NEs.
  - Access Groups and Network Enablers
    Network Enablers (NEs) are deployed in access groups, with all NEs in all access groups being fully meshed with all engines.
  - Network Enabler Kubernetes Services
    A number of Kubernetes services are created by Helm when it creates the engine services to allow connection to and from Network Enablers (NEs).
  - Installing the Multus Plug-in
    The Multus Container Network Interface (CNI) plug-in is a third-party tool for attaching multiple network interfaces (with static or dynamic IP addresses) to a pod. In a Network Enabler (NE) deployment, you use it to attach static IP addresses to the NE pod.
  - Configure Network Enablers
    Make configuration changes to enable Call Control Framework (CCF) in the Kubernetes cluster.
  - Deploying the Network Enabler
    Network Enablers (NEs) in Kubernetes clusters are deployed using the MATRIXX Helm chart. For information, see configuring MATRIXX using Helm.
  - Monitoring Network Enabler with Prometheus
    Network Enabler (NE) SNMP statistics can be monitored with Prometheus.
  - Network Enabler Logging in Kubernetes
    Network Enablers (NEs) log what are normally the contents of the mtx_debug.log file to the Kubernetes logging function.
- 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

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.

MATRIXX Engine, proxies, and other components in a Kubernetes cluster interact with NEs the same as they would in a non-containerized installation, although CCF must be configured in the global configuration.

The image keeps the standard base Linux /sbin/init command as its default start-up command, allowing the image to be used outside of Kubernetes and logged into using Docker if required. Kubernetes use overrides the Linux initialization to run a custom initialization script. The script configures and starts MTX services using process_control.cfg configured for non-daemon operation and with logging redirected to stdout, such that logs are available to Kubernetes logging.

NEs support the SIGTRAN protocol to connect to the network STPs which use Stream Control Transmission Protocol (SCTP) as a transport protocol. Nodes that host NEs must have the lksctp-tools and lksctp-tools-devel packages installed.

Note: SCTP support in Kubernetes v1.15 is an Alpha feature-gate and as such must be explicitly enabled. The way this is configured depends on the Kubernetes implementation being used and requires ensuring that the following is set: --feature-gates="SCTPSupport=true". In Kubernetes v1.20 and later versions, SCTP is enabled by default and this configuration is not required.
