|
|
<p>Anytime we reference a TLS secret, we mean a PEM-encoded X.509, RSA (2048) secret.</p>
|
|
<p>You can generate a self-signed certificate and private key with:</p>
|
|
<div class="highlight"><pre><span></span><code>$ openssl req -x509 -nodes -days <span class="m">365</span> -newkey rsa:2048 -keyout <span class="si">${</span><span class="nv">KEY_FILE</span><span class="si">}</span> -out <span class="si">${</span><span class="nv">CERT_FILE</span><span class="si">}</span> -subj <span class="s2">"/CN=</span><span class="si">${</span><span class="nv">HOST</span><span class="si">}</span><span class="s2">/O=</span><span class="si">${</span><span class="nv">HOST</span><span class="si">}</span><span class="s2">"</span>
|
|
</code></pre></div>
|
|
|
|
<p>Then create the secret in the cluster via:</p>
|
|
<div class="highlight"><pre><span></span><code>kubectl create secret tls <span class="si">${</span><span class="nv">CERT_NAME</span><span class="si">}</span> --key <span class="si">${</span><span class="nv">KEY_FILE</span><span class="si">}</span> --cert <span class="si">${</span><span class="nv">CERT_FILE</span><span class="si">}</span>
|
|
</code></pre></div>
|
|
|
|
<p>The resulting secret will be of type <code>kubernetes.io/tls</code>.</p>
|
|
<h2 id="default-ssl-certificate">Default SSL Certificate<a class="headerlink" href="#default-ssl-certificate" title="Permanent link"> ¶</a></h2>
|
|
<p>NGINX provides the option to configure a server as a catch-all with
|
|
<a href="http://nginx.org/en/docs/http/server_names.html">server_name</a>
|
|
for requests that do not match any of the configured server names.
|
|
This configuration works without out-of-the-box for HTTP traffic.
|
|
For HTTPS, a certificate is naturally required.</p>
|
|
<p>For this reason the Ingress controller provides the flag <code>--default-ssl-certificate</code>.
|
|
The secret referred to by this flag contains the default certificate to be used when
|
|
accessing the catch-all server.
|
|
If this flag is not provided NGINX will use a self-signed certificate.</p>
|
|
<p>For instance, if you have a TLS secret <code>foo-tls</code> in the <code>default</code> namespace,
|
|
add <code>--default-ssl-certificate=default/foo-tls</code> in the <code>nginx-controller</code> deployment.</p>
|
|
<p>The default certificate will also be used for ingress <code>tls:</code> sections that do not
|
|
have a <code>secretName</code> option.</p>
|
|
<h2 id="ssl-passthrough">SSL Passthrough<a class="headerlink" href="#ssl-passthrough" title="Permanent link"> ¶</a></h2>
|
|
<p>The <a href="../cli-arguments/"><code>--enable-ssl-passthrough</code></a> flag enables the SSL Passthrough feature, which is disabled by
|
|
default. This is required to enable passthrough backends in Ingress objects.</p>
|
|
<div class="admonition warning">
|
|
<p class="admonition-title">Warning</p>
|
|
<p>This feature is implemented by intercepting <strong>all traffic</strong> on the configured HTTPS port (default: 443) and handing
|
|
it over to a local TCP proxy. This bypasses NGINX completely and introduces a non-negligible performance penalty.</p>
|
|
</div>
|
|
<p>SSL Passthrough leverages <a href="https://en.wikipedia.org/wiki/Server_Name_Indication">SNI</a> and reads the virtual domain from the TLS negotiation, which requires compatible
|
|
clients. After a connection has been accepted by the TLS listener, it is handled by the controller itself and piped back
|
|
and forth between the backend and the client.</p>
|
|
<p>If there is no hostname matching the requested host name, the request is handed over to NGINX on the configured
|
|
passthrough proxy port (default: 442), which proxies the request to the default backend.</p>
|
|
<div class="admonition note">
|
|
<p class="admonition-title">Note</p>
|
|
<p>Unlike HTTP backends, traffic to Passthrough backends is sent to the <em>clusterIP</em> of the backing Service instead of
|
|
individual Endpoints.</p>

<h2 id="http-strict-transport-security">HTTP Strict Transport Security<a class="headerlink" href="#http-strict-transport-security" title="Permanent link"> ¶</a></h2>
|
|
<p>HTTP Strict Transport Security (HSTS) is an opt-in security enhancement specified
|
|
through the use of a special response header. Once a supported browser receives
|
|
this header that browser will prevent any communications from being sent over
|
|
HTTP to the specified domain and will instead send all communications over HTTPS.</p>
|
|
<p>HSTS is enabled by default.</p>
|
|
<p>To disable this behavior use <code>hsts: "false"</code> in the configuration <a href="../nginx-configuration/configmap/">ConfigMap</a>.</p>
|
|
<h2 id="server-side-https-enforcement-through-redirect">Server-side HTTPS enforcement through redirect<a class="headerlink" href="#server-side-https-enforcement-through-redirect" title="Permanent link"> ¶</a></h2>
|
|
<p>By default the controller redirects HTTP clients to the HTTPS port
|
|
443 using a 308 Permanent Redirect response if TLS is enabled for that Ingress.</p>
|
|
<p>This can be disabled globally using <code>ssl-redirect: "false"</code> in the NGINX <a href="../nginx-configuration/configmap/">config map</a>,
|
|
or per-Ingress with the <code>nginx.ingress.kubernetes.io/ssl-redirect: "false"</code>
|
|
annotation in the particular resource.</p>
|
|
<div class="admonition tip">
|
|
<p class="admonition-title">Tip</p>
|
|
<p>When using SSL offloading outside of cluster (e.g. AWS ELB) it may be useful to enforce a
|
|
redirect to HTTPS even when there is no TLS certificate available.
|
|
This can be achieved by using the <code>nginx.ingress.kubernetes.io/force-ssl-redirect: "true"</code>
|
|
annotation in the particular resource.</p>

<div class="admonition tip">

<p class="admonition-title">Tip</p>

<p>Kube-Lego has reached end-of-life and is being

replaced by <a href="https://github.com/jetstack/cert-manager/">cert-manager</a>.</p>
|

</div>

|
<p><a href="https://github.com/jetstack/kube-lego">Kube-Lego</a> automatically requests missing or expired certificates from <a href="https://letsencrypt.org">Let's Encrypt</a>
|
|
by monitoring ingress resources and their referenced secrets.</p>
|
|
<p>To enable this for an ingress resource you have to add an annotation:</p>
|
|
<div class="highlight"><pre><span></span><code><span class="go">kubectl annotate ing ingress-demo kubernetes.io/tls-acme="true"</span>
|
|
</code></pre></div>
|
|
|
|
<p>To setup Kube-Lego you can take a look at this <a href="https://github.com/jetstack/kube-lego/tree/master/examples">full example</a>.
|
|
The first version to fully support Kube-Lego is Nginx Ingress controller 0.8.</p>
|
|
<h2 id="default-tls-version-and-ciphers">Default TLS Version and Ciphers<a class="headerlink" href="#default-tls-version-and-ciphers" title="Permanent link"> ¶</a></h2>
|
|
<p>To provide the most secure baseline configuration possible,</p>
|
|
<p>nginx-ingress defaults to using TLS 1.2 and 1.3 only, with a <a href="../nginx-configuration/configmap/#ssl-ciphers">secure set of TLS ciphers</a>.</p>
|
|
<h3 id="legacy-tls">Legacy TLS<a class="headerlink" href="#legacy-tls" title="Permanent link"> ¶</a></h3>
|
|
<p>The default configuration, though secure, does not support some older browsers and operating systems.</p>
|
|
<p>For instance, TLS 1.1+ is only enabled by default from Android 5.0 on. At the time of writing,
|
|
May 2018, <a href="https://developer.android.com/about/dashboards/#Platform">approximately 15% of Android devices</a>
|
|
are not compatible with nginx-ingress's default configuration.</p>
|
|
<p>To change this default behavior, use a <a href="../nginx-configuration/configmap/">ConfigMap</a>.</p>
|
|
<p>A sample ConfigMap fragment to allow these older clients to connect could look something like the following
|
|
(generated using the Mozilla SSL Configuration Generator)<a href="https://ssl-config.mozilla.org/#server=nginx&config=old">mozilla-ssl-config-old</a>:</p>
