4.2 Configure the values.yaml File

The installation bundle contains values.yaml file, the manifest file of the application, which contains the deployment configuration details for MicroTx.

Replace the sample values in the values.yaml file to provide the environment details, image details, and configuration details to deploy MicroTx.

While deploying MicroTx to a Kubernetes cluster, Helm pulls the MicroTx image from the remote Docker registry. In the values.yaml file, specify the image to pull and the credentials to use when pulling the images.

To provide configuration details for MicroTx:

1. Open one of the following values.yaml file in any code editor. These files contain sample values. Select a file based on the container platform that you are using, whether you want to use an Istio service mesh, and whether you want to deploy the MicroTx Free or Enterprise edition.

   The following table provides the relative path of the values.yaml file from installation_directory\otmm-RELEASE\otmm\helmcharts folder.

   File Path	Container Platform	Description
   .\tmm\ee	Kubernetes	Deploys MicroTx Enterprise edition in Istio service mesh.
   .\tmm	Kubernetes	Deploys MicroTx Free in Istio service mesh.
   .\tmmk8s\ee	Kubernetes	Deploys MicroTx Enterprise edition without using Istio service mesh.
   .\tmmk8s	Kubernetes	Deploys MicroTx Free without using Istio service mesh.
   .\tmm-istio-openshift\ee	OpenShift	Deploys MicroTx Enterprise edition in Istio service mesh.
   .\tmm-istio-openshift	OpenShift	Deploys MicroTx Free in Istio service mesh.
   .\tmm-openshift\ee	OpenShift	Deploys MicroTx Enterprise edition without using Istio service mesh.
   .\tmm-openshift	OpenShift	Deploys MicroTx Free without using Istio service mesh.

2. Replace the sample values with values that are specific to your environment.
   The tables in this section describe the properties for the environment, storage, authorization, authentication, and other configuration details that are required to install MicroTx.
3. Save your changes.

Topics

• Environment Details
  In the values.yaml file, provide information about the environment details in which you want to install MicroTx.
• Image Properties
  Under tmmImage, provide information about the MicroTx Docker image. It is mandatory to provide values for these properties.
• Transaction Coordinator Properties
  Under tmmConfiguration, provide information to configure MicroTx.
• Data Store Properties
  MicroTx uses a data store for persistence of the transaction state and to store the transaction logs.
• Istio Details
  If you are using an Istio service mesh, provide details about the Istio ingress gateway that you have set up in the values.yaml file.
• Caching Properties
  You can enable caching to improve performance. It optimizes the read and write operations for the transaction logs that are stored in etcd or Oracle Database.
• Logging Properties
  Under logging, provide details for the MicroTx logs.
• Metrics Property
  Under metrics, enable Prometheus to scrape the metrics logs of the MicroTx coordinator.
• Authorization Properties
  MicroTx supports authorization across participant services and coordinator by propagating the JWT token in every request.
• Authentication Properties
  Under authentication, enable JSON Web Token (JWT) authentication.
• Identity Provider Properties
  Under identityProvider, enter property values for the JSON Web Token (JWT) which the MicroTx coordinator uses for authentication.
• Encryption Key Properties
  Under encryption, specify the encryption key that MicroTx uses to encrypt the access and refresh tokens. You must provide values for these properties if you have enabled authTokenPropagationEnabled under tmmConfiguration.authorization.
• Transaction Token Properties
  Under transactionToken, specify the key pair that you want to use for transaction token.
• Console Configuration Properties
  Under tmmConsoleConfiguration, specify the properties for the MicroTx console.
