shows how to configure Istio to perform <a href=/v1.1/help/glossary/#tls-origination>TLS origination</a> for traffic to an external service.
|
|
The <a href=/v1.1/docs/examples/advanced-gateways/egress-gateway>Configure an Egress Gateway</a> example shows how to configure
|
|
Istio to direct egress traffic through a dedicated <em>egress gateway</em> service.
|
|
This example combines the previous two by describing how to configure an egress gateway to perform
|
|
TLS origination for traffic to external services.</p><h2 id=before-you-begin>Before you begin</h2><ul><li><p>Setup Istio by following the instructions in the <a href=/v1.1/docs/setup/>Installation guide</a>.</p></li><li><p>Start the <a href=https://github.com/istio/istio/tree/release-1.1/samples/sleep>sleep</a> sample

<a href=/v1.1/docs/examples/advanced-gateways/egress-tls-origination/>TLS Origination for Egress Traffic</a> example,

|
only this time using an egress gateway. Note that in this case the TLS origination will
