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.

This example file provides a basic configuration for a small-footprint hybrid runtime installation, a configuration that is suitable for a your first installation.
overrides.yamland add the required property values, shown below. A detailed description of each property is also provided below:
overrides.yamlfile has the following structure and syntax. Values in red, bold italics are property values that you must provide. They are also described in the table below.

The configuration file tells Kubernetes how to deploy the hybrid components to a cluster. Next, you will apply this configuration to your cluster.
