3.4.1 Considerations for Deployment on Kubernetes

Consider the following factors while deploying MicroTx on Kubernetes.

The installation bundle provides Helm charts and this document provides details for a sample deployment of MicroTx in a Kubernetes cluster with Istio service mesh. If you are using another service mesh in a Kubernetes cluster, create your own Helm charts.

Supported Kubernetes Platforms

Deploy MicroTx in a Kubernetes cluster that is running in your data center or your cloud environment. MicroTx is tested with Kubernetes 1.21.x or compatible versions on the following platforms:

• Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE). See Creating a Kubernetes Cluster in Oracle Cloud Infrastructure documentation.
• Minikube
• Oracle Linux Container Native Environment

Deployment Across Multiple Kubernetes Clusters

You can deploy your application microservices and MicroTx within a single Istio service mesh in a single Kubernetes cluster.

When your application microservices are distributed across multiple Kubernetes cluster, or if you want MicroTx to communicate with Oracle Database or Tuxedo, then you can deploy MicroTx in a separate Kubernetes cluster. In such a scenario, each Kubernetes cluster will contain an Istio service mesh. You will have to configure ingress and egress gateways to enable communication between multiple Istio services meshes.
