Step 6: Create the overrides

Version 1.13 keyboard_arrow_down

Specify configuration overrides

The Apigee hybrid installer uses defaults for many settings. However, there are a few settings that do not have defaults. You must provide values for these settings, as explained next.

Before you begin

We recommend you review the following scenarios to determine if you want to configure your cluster for them. These configurations are optional.

Configure the cluster

By convention, configuration overrides are written in a file named overrides.yaml typically stored in your $APIGEE_HELM_CHARTS_HOME directory.

  1. Create a new file named overrides.yaml in your $APIGEE_HELM_CHARTS_HOME directory.

    The overrides.yaml provides the configuration for your unique Apigee hybrid installation. The overrides file in this step provides a basic configuration for a small-footprint hybrid runtime installation, suitable for your first installation.

  2. In overrides.yaml, add the required property values, shown below. A detailed description of each property is provided below.

    Select the tab for your installation, production, Production or non-production (demo, evaluation, or proof-of-concept installations), Non-prod depending on your choice in Step 4: Create service accounts.

    For installations in production environments, look at the storage requirements for the Cassandra database in Configure Cassandra for production.

    If you are installing Apigee hybrid on GKE and you plan to use Workload Identity to authenticate hybrid components, select either the Prod: Workload Identity or Non-prod: Workload Identity tab to configure your overrides.yaml file.

    Production

    Make sure the overrides.yaml file has the following structure and syntax. Values in red, bold italics are property values that you must provide. You can edit their values on this page. They are described in the table below.

    There are differences between the different platforms for the Google Cloud project region and Kubernetes cluster region. Choose the platform where you are installing Apigee hybrid.

  3. When you are finished, save the file.

The following table describes each of the property values that you must provide in the overrides file. For more information, see Configuration property reference.

Variable Description UNIQUE_INSTANCE_IDENTIFIER

A unique string to identify this instance. This can be any combination of letters and numbers up to 63 characters.

You can create multiple organizations in the same cluster, but the instanceID must be the same for all orgs in the same Kubernetes cluster.

APIGEE_NAMESPACE

The Kubernetes namespace for your Apigee hybrid components.

The default value is apigee.

ANALYTICS_REGION In GKE, You must set this value to the same region where the cluster is running. In all other platforms, select the closest analytics region to your cluster that has Analytics support (see the table in Part 1, Step 2: Create an organization. This is the value you assigned to the environment variable ANALYTICS_REGION previously. PROJECT_ID Identifies the Google Cloud project where the apigee-logger and the apigee-metrics push their data. This is the value assigned to the environment variable PROJECT_ID. CLUSTER_NAME Your Kubernetes cluster name. This is the value assigned to the environment variable CLUSTER_NAME. CLUSTER_LOCATION The region where the cluster is running. This is the region where you created the cluster in Step 1: Create a cluster.

This is the value you assigned to the environment variable CLUSTER_LOCATION previously.

ORG_NAME The ID of your Apigee hybrid organization. This is the value assigned to the environment variable ORG_NAME. CONTROL_PLANE_LOCATION Required if you are using Data residency with your Apigee hybrid installation. This is the location where customer core content like proxy bundles is stored. For a list see Available Apigee API control plane regions. It is the value assigned to the CONTROL_PLANE_LOCATION environment variable in Step 2: Create an organization. ENVIRONMENT_GROUP_NAME The name of the environment group your environments are assigned to. This is the group you created in Project and org setup - Step 3: Create an environment group. This is the value assigned to the environment variable ENV_GROUP. PATH_TO_CERT_FILE
PATH_TO_KEY_FILE Enter the path and filename of the self-signed TLS key and certificate files that you generated previously in Step 5: Create TLS certificates. These files must be located in the APIGEE_HELM_CHARTS_HOME/apigee-virtualhosts/certs directory. For example: 
sslCertPath: certs/keystore.crt
sslKeyPath: certs/keystore.key
 INGRESS_NAME The name of the Apigee ingress gateway for your deployment. This can be any name that meets the following requirements:

See ingressGateways[].name in the Configuration property reference

SVC_ANNOTATIONS_KEY: SVC_ANNOTATIONS_VALUE (Optional). This is a key-value pair that provides annotations for your default ingress service. Your cloud platform uses annotations to help configure your hybrid installation, for example setting the loadbalancer type to either internal or external.

Annotations vary from platform to platform. Refer to your platform documentation for required and suggested annotations.

Comment out or delete this section if you are not using it.

SVC_LOAD_BALANCER_IP (Optional). An IP address you have reserved for your load balancer. On platforms that support specifying the load balancer IP address, the load balancer will be created with this IP address. On platforms that do not allow you to specify the load balancer IP, this property is ignored.

Comment out or delete this section if you are not using it.

ENVIRONMENT_NAME Use the same name that you used when you created an environment in the UI, as explained in Project and org setup - Step 3: Create an environment group. *_SERVICE_ACCOUNT_FILEPATH The path and filename account of the service account JSON files in your corresponding chart directory. Provide the names with the path relative to the chart directory. For example:

For non-production environments, the name of the single service account is PROJECT_ID-non-prod.json by default.

For production environments, the name of the service account key file that you generated with the create-service-account tool in Step 4: Create service accounts.

You can see the service account files in each corresponding chart directory.

The default names of the and corresponding chart directories for the service accounts are:

Service account file name Chart directory
Storage Object Admin PROJECT_ID-apigee-cassandra.json apigee-datastore/
Logs Writer PROJECT_ID-apigee-logger.json apigee-telemetry/
Apigee Connect Agent PROJECT_ID-apigee-mart.json apigee-org/
Monitoring Metric Writer PROJECT_ID-apigee-metrics.json apigee-telemetry/
No role required PROJECT_ID-apigee-runtime.json apigee-env/
Apigee Synchronizer Manager PROJECT_ID-apigee-synchronizer.json apigee-env/
Apigee Analytics Agent PROJECT_ID-apigee-udca.json apigee-org/
Apigee Runtime Agent PROJECT_ID-apigee-watcher.json apigee-org/
*_SERVICE_ACCOUNT_EMAIL The service account email addresses for the Google service accounts (GSA) you need to supply if you are using Workload Identity on GKE. These are the service accounts you created in Step 4: Create service accounts. You can find the email addresses for the service accounts with the following command: 
gcloud iam service-accounts list --project ${PROJECT_ID} --filter "apigee"

Summary

The configuration file tells Kubernetes how to deploy the hybrid components to a cluster. Next, you will enable synchronizer access so the Apigee runtime and management planes will be able to communicate.
