|
|
By default, the timeout is 15 seconds, but in this task you override the <code>reviews</code> service
|
|
timeout to 1 second.
|
|
To see its effect, however, you also introduce an artificial 2 second delay in calls

to the <code>ratings</code> service.</p><ol><li><p>Route requests to v2 of the <code>reviews</code> service, i.e., a version that calls the <code>ratings</code> service:</p><pre><code class=language-bash>cat <<EOF | kubectl apply -f -

|
|
because there is a hard-coded retry in the <code>productpage</code> service, so it calls the timing out <code>reviews</code> service
|
|
twice before returning.</p></blockquote></li></ol><h2 id=understanding-what-happened>Understanding what happened</h2><p>In this task, you used Istio to set the request timeout for calls to the <code>reviews</code>
|
|
microservice to half a second instead of the default of 15 seconds.
|
|
Since the <code>reviews</code> service subsequently calls the <code>ratings</code> service when handling requests,
|
|
you used Istio to inject a 2 second delay in calls to <code>ratings</code> to cause the
|
|
<code>reviews</code> service to take longer than half a second to complete and consequently you could see the timeout in action.</p><p>You observed that instead of displaying reviews, the Bookinfo product page (which calls the <code>reviews</code> service to populate the page) displayed
|
|
the message: Sorry, product reviews are currently unavailable for this book.
|
|
This was the result of it receiving the timeout error from the <code>reviews</code> service.</p><p>If you examine the <a href=/v1.0/docs/tasks/traffic-management/fault-injection/>fault injection task</a>, you'll find out that the <code>productpage</code>
|
|
microservice also has its own application-level timeout (3 seconds) for calls to the <code>reviews</code> microservice.
|
|
Notice that in this task you used an Istio route rule to set the timeout to half a second.
|
|
Had you instead set the timeout to something greater than 3 seconds (such as 4 seconds) the timeout
|
|
would have had no effect since the more restrictive of the two takes precedence.
|
|
More details can be found <a href=/v1.0/docs/concepts/traffic-management/#failure-handling-faq>here</a>.</p><p>One more thing to note about timeouts in Istio is that in addition to overriding them in route rules,
|
|
as you did in this task, they can also be overridden on a per-request basis if the application adds
|
|
an <code>x-envoy-upstream-rq-timeout-ms</code> header on outbound requests. In the header,
|
|
the timeout is specified in milliseconds instead of seconds.</p><h2 id=cleanup>Cleanup</h2><ul><li><p>Remove the application routing rules:</p><pre><code class=language-command>$ kubectl delete -f @samples/bookinfo/networking/virtual-service-all-v1.yaml@</code></pre><a hidden style=display:none href=https://raw.githubusercontent.com/istio/istio/release-1.0/samples/bookinfo/networking/virtual-service-all-v1.yaml></a></li><li><p>If you are not planning to explore any follow-on tasks, see the
