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.
- If you are planning on installing hybrid in multiple regions, read Multi-region deployment before continuing.
- Apigee hybrid provides default passwords for the Cassandra users. Apigee recommends changing the default user passwords. See Configuring TLS for Cassandra for details.
- If you want to configure the storage and heap settings for Cassandra, see Configure storage and heap settings.
- As described in Part 1: Project and Org setup--Step 1: Enable APIs, For production installation scenarios, configure persistent solid state disk (SSD) storage for Cassandra. Apigee does not support using local SSDs for Apigee hybrid. For details, see Add SSD storage for production deployments.
Configure the cluster
By convention, configuration overrides are written in a file named overrides.yaml
typically stored in your $APIGEE_HELM_CHARTS_HOME
directory.
- Create a new file named
overrides.yaml
in your$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. - 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.

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.
