<p class="admonition-title">Important</p>
<p>No matter the method you use for upgrading, <em>if you use template overrides,
make sure your templates are compatible with the new version of ingress-nginx</em>.</p>
</div>
<h2 id="without-helm">Without Helm<a class="headerlink" href="#without-helm" title="Permanent link"></a></h2>
<p>To upgrade your ingress-nginx installation, it should be enough to change the version of the image
in the controller Deployment.</p>
<p>I.e. if your deployment resource looks like (partial example):</p>
<div class="highlight"><pre><span></span><code><span class="nt">kind</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">Deployment</span>
<span class="nt">metadata</span><span class="p">:</span>
<span class="nt">name</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">nginx-ingress-controller</span>
<span class="nt">namespace</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">ingress-nginx</span>
<span class="nt">spec</span><span class="p">:</span>
<span class="nt">replicas</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">1</span>
<span class="nt">selector</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">...</span>
<span class="nt">template</span><span class="p">:</span>
<span class="nt">metadata</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">...</span>
<span class="nt">spec</span><span class="p">:</span>
<span class="nt">containers</span><span class="p">:</span>
<span class="p p-Indicator">-</span> <span class="nt">name</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">nginx-ingress-controller</span>
<span class="nt">image</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.30.0</span>
<span class="nt">args</span><span class="p">:</span> <span class="l l-Scalar l-Scalar-Plain">...</span>
</code></pre></div>
<p>simply change the <code>0.30.0</code> tag to the version you wish to upgrade to.
The easiest way to do this is e.g. (do note you may need to change the name parameter according to your installation):</p>
<div class="highlight"><pre><span></span><code>kubectl set image deployment/nginx-ingress-controller \
nginx-ingress-controller=quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.32.0
</code></pre></div>
<p>For interactive editing, use <code>kubectl edit deployment nginx-ingress-controller</code>.</p>
<h2 id="with-helm">With Helm<a class="headerlink" href="#with-helm" title="Permanent link"></a></h2>
<p>If you installed ingress-nginx using the Helm command in the deployment docs so its name is <code>ngx-ingress</code>,
you should be able to upgrade using</p>
<div class="highlight"><pre><span></span><code>helm upgrade --reuse-values ngx-ingress stable/nginx-ingress
</code></pre></div>
