Everything lives in Git and Flux reconciles it. But there&rsquo;s still one pair of commands I reach for constantly when developing or debugging an app:</p> <div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"><code class="language-bash" data-lang="bash"><span style="display:flex;"><span>k kustomize <span style="color:#75715e"># inspect the rendered output</span> </span></span><span style="display:flex;"><span>k apply -k . <span style="color:#75715e"># apply it manually when I need to</span> </span></span></code></pre></div><p>This post walks through what these commands actually do, how they fit into a Flux-based workflow, and a real example from my <code>n8n</code> deployment on a Raspberry Pi 5 k3s cluster.</p>
