This component is responsible for provisioning ZScaler Private Access Connector instances on Amazon Linux 2 AMIs.

Prior to provisioning this component, it is required that a SecureString SSM Parameter containing the ZScaler App Connector Provisioning Key is populated in each account corresponding to the regional stack the component is deployed to, with the name of the SSM Parameter matching the value of var.zscaler_key.

This parameter should be populated using chamber, which is included in the geodesic image:

chamber write zscaler key <value>

Where <value> is the ZScaler App Connector Provisioning Key. For more information on how to generate this key, see: ZScaler documentation on Configuring App Connectors.

Usage

Stack Level: Regional

The typical stack configuration for this component is as follows:

components:
  terraform:
    zscaler:
      vars:
        zscaler_count: 2

Preferably, regional stack configurations can be kept DRY by importing catalog/zscaler via the imports list at the top of the configuration.

import:
  ...
  - catalog/zscaler
