4.3 Install MicroTx

Use Helm to install MicroTx on a Kubernetes cluster.

1. Navigate to the helmcharts folder for MicroTx.

   cd installation_directory/otmm-RELEASE/otmm/helmcharts

2. Deploy MicroTx using the configuration details provided in the values.yaml file. Run one of the following commands based on whether you want to install only the coordinator or you want to install the console as well.

   Syntax

   helm install <release name> --namespace <namespace> <chart directory> --values <values.yaml>

   Example

   • Use the following command to install MicroTx as an application named tmm-app in the otmm namespace.

     helm install tmm-app --namespace otmm tmm/ --values tmm/values.yaml

   • Use the following command to install the MicroTx console and MicroTx as an application named tmm-app in the otmm namespace.

     helm install tmm-app --namespace otmm tmm/ --values tmm/ee/values.yaml

   Where,

   • tmm-app is the name of the application that you want to create.

   • otmm is the namespace in Kubernetes cluster, where you want to install MicroTx.

   • installation_directory/otmm-RELEASE/otmm/helmcharts/tmm is the folder that contains the chart.yaml file for MicroTx.
   • installation_directory/otmm-RELEASE/otmm/helmcharts/tmm/values.yaml is the location of the values.yaml file, the application's manifest file, in your local machine. This file contains the deployment configuration details for MicroTx. It does not contain properties that are specific to the MicroTx console.
   • installation_directory/otmm-RELEASE/otmm/helmcharts/tmm/ee/values.yaml is the location of the values.yaml file, the application's manifest file, in your local machine. This file contains the deployment configuration details for the MicroTx coordinator as well as the MicroTx console.
