Configure static IP addresses

Version 1.2 (unsupported)keyboard_arrow_down

Google recommends that you create static IP addresses for the two ingress gateways that are exposed outside the cluster:

Gateway Description
apigee-mart-istio-ingressgateway The Istio ingress gateway used by the MART service to communicate with the management plane.
istio-ingressgateway The Istio ingress gateway used to send and receive API proxy traffic by the message processor load balancers.

These gateways are provisioned with load balancers. By default, the IP addresses for these load balancers are ephemeral. That means whenever one of the services is deleted and restored, it gets a new load balancer IP.

This topic explains how to define static IP addresses for Apigee hybrid deployed on GKE and Anthos GKE (GKE On-Prem).

Configure static IP addresses on GKE

  1. Follow the instructions in Reserving a static external IP address to create two static IP addresses. You can give the addresses any name you wish, for example: apigee-hybrid-mart and apigee-hybrid-runtime. When you finish, you will have two IP numbers to use in the cluster configuration in the next step. For example: 35.225.131.189 and 34.66.75.196
  2. In your overrides file, add the following loadBalancerIP configurations to the ingress component:

    Syntax

    The configuration has the following structure and syntax. Values in red, bold italics are property values that you must provide:

    ingress:
  enableAccesslog: true
  runtime:
    loadBalancerIP: runtime_IP
  mart:
    loadBalancerIP: mart_IP

    Example

    The following example shows the completed configuration with example property values added:

    ingress:
  enableAccesslog: true
  runtime:
    loadBalancerIP: 35.225.131.189
  mart:
    loadBalancerIP: 34.66.75.196

  3. Apply your overrides file to the cluster. Because only the istio component needs to be updated, you can use the -c istio flag. For example:

    $APIGEECTL_HOME/apigeectl init -f my-overrides.yaml -c istio

Configure static IP addresses for Anthos GKE

  1. Refer to the Anthos GKE documentation and create two static IP addresses by following the Anthos GKE specific instructions. When you finish, you will have two IP numbers to use in the cluster configuration in the next step. For example: 35.225.131.189 and 34.66.75.196
  2. Open your overrides file.
  3. Add the following configuration for ingress:

    Syntax

    The configuration has the following structure and syntax. Values in red, bold italics are property values that you must provide:

    ingress:
  enableAccesslog: true
  runtime:
    loadBalancerIP: runtime_IP
  mart:
    loadBalancerIP: mart_IP

    Example

    The following example shows the completed configuration with example property values added:

    ingress:
  enableAccesslog: true
  runtime:
    loadBalancerIP: 35.225.131.189
  mart:
    loadBalancerIP: 34.66.75.196
  4. Save the file.

  5. Apply your overrides file to the cluster. Because only the istio component needs to be updated, you can use the -c istio flag. For example:

    $APIGEECTL_HOME/apigeectl init -f my-overrides.yaml -c istio
