<h4 id="aws">AWS<a class="headerlink" href="#aws" title="Permanent link">¶</a></h4>
|
|
<p>In AWS we use an Elastic Load Balancer (ELB) to expose the NGINX Ingress controller behind a Service of <code class="codehilite">Type=LoadBalancer</code>.
|
|
Since Kubernetes v1.9.0 it is possible to use a classic load balancer (ELB) or network load balancer (NLB)
|
|
Please check the <a href="https://aws.amazon.com/elasticloadbalancing/details/">elastic load balancing AWS details page</a></p>
|
|
<h5 id="elastic-load-balancer-elb">Elastic Load Balancer - ELB<a class="headerlink" href="#elastic-load-balancer-elb" title="Permanent link">¶</a></h5>
|
|
<p>This setup requires to choose in which layer (L4 or L7) we want to configure the ELB:</p>
|
|
<ul>
|
|
<li><a href="https://en.wikipedia.org/wiki/OSI_model#Layer_4:_Transport_Layer">Layer 4</a>: use TCP as the listener protocol for ports 80 and 443.</li>
|
|
<li><a href="https://en.wikipedia.org/wiki/OSI_model#Layer_7:_Application_Layer">Layer 7</a>: use HTTP as the listener protocol for port 80 and terminate TLS in the ELB</li>
|
|
</ul>
|
|
<p>For L4:</p>
|
|
<p>Check that no change is necessary with regards to the ELB idle timeout. In some scenarios, users may want to modify the ELB idle timeout, so please check the <a href="#elb-idle-timeouts">ELB Idle Timeouts section</a> for additional information. If a change is required, users will need to update the value of <code class="codehilite">service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout</code> in <code class="codehilite">provider/aws/service-l4.yaml</code></p>
|
|
<p>Then execute:</p>
|
|
<div class="codehilite"><pre><span></span><span class="go">kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/service-l4.yaml</span>
|
|
<span class="go">kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/patch-configmap-l4.yaml</span>
|
|
</pre></div>
|
|
|
|
<p>For L7:</p>
|
|
<p>Change line of the file <code class="codehilite">provider/aws/service-l7.yaml</code> replacing the dummy id with a valid one <code class="codehilite">"arn:aws:acm:us-west-2:XXXXXXXX:certificate/XXXXXX-XXXXXXX-XXXXXXX-XXXXXXXX"</code></p>
|
|
<p>Check that no change is necessary with regards to the ELB idle timeout. In some scenarios, users may want to modify the ELB idle timeout, so please check the <a href="#elb-idle-timeouts">ELB Idle Timeouts section</a> for additional information. If a change is required, users will need to update the value of <code class="codehilite">service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout</code> in <code class="codehilite">provider/aws/service-l7.yaml</code></p>
|
|
<p>Then execute:</p>
|
|
<div class="codehilite"><pre><span></span><span class="go">kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/service-l7.yaml</span>
|
|
<span class="go">kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/patch-configmap-l7.yaml</span>
|
|
</pre></div>
|
|
|
|
<p>This example creates an ELB with just two listeners, one in port 80 and another in port 443</p>
|
|
<p><img alt="Listeners" src="../images/elb-l7-listener.png" /></p>
|
|
<h5 id="elb-idle-timeouts">ELB Idle Timeouts<a class="headerlink" href="#elb-idle-timeouts" title="Permanent link">¶</a></h5>
|
|
<p>In some scenarios users will need to modify the value of the ELB idle timeout. Users need to ensure the idle timeout is less than the <a href="http://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout">keepalive_timeout</a> that is configured for NGINX. By default NGINX <code class="codehilite">keepalive_timeout</code> is set to <code class="codehilite">75s</code>.</p>
|
|
<p>The default ELB idle timeout will work for most scenarios, unless the NGINX <a href="http://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout">keepalive_timeout</a> has been modified, in which case <code class="codehilite">service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout</code> will need to be modified to ensure it is less than the <code class="codehilite">keepalive_timeout</code> the user has configured.</p>
|
|
<p><em>Please Note: An idle timeout of <code class="codehilite">3600s</code> is recommended when using WebSockets.</em></p>
|
|
<p>More information with regards to idle timeouts for your Load Balancer can be found in the <a href="https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/config-idle-timeout.html">official AWS documentation</a>.</p>
