ref: Add embded rust and router

- Use embed rust to load and resolve file from `content/post` folder, so
the whole process is a bit more dynamic.

- Add router to to resolve the path. It is the first step to try to get
the code a bit cleaner.

+    <p>
+        If you turned off your DHCP server follow these steps to connect to FritzBox settings.
+        <br/>
+    <ul>
+        <li> Set your computer IP to 170.254.1.2 and your mask to 255.255.0.0</li>
+        <li> Then go to 169.254.1.1, login and re-enable the DHCP server:</li>
+    </ul>
+    </p>
+    <p>
+        On gnome turn the wired connection off on again to apply the settings.
+    </p>
+    <p>
+        <strong>Note</strong>: why in the hell does FritzBox 7490 require a land-line telephone to be physically factory

+    <h2>K8S private gitlab registry using podman</h2>
+    <p>
+        This is based on <a
+            href="https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/">Log in to
+        Docker Hub</a>. It is just a bit different to use podman.
+    </p>
+    <p>
+        First we should take a look at podman-login man page:
+    <pre>
+        <code>man podman login</code>
+    </pre>
+    </p>
+    <p>
+        It will give some valueable information like the location of auth.json file. Now we can login using podman:
+    <pre>
+        <code>podman login registry.gitlab.com</code>
+    </pre>
+    </p>
+    <p>Then check the <i> auth.json </i>file located at <i>${XDG_RUNTIME_DIR}/containers/auth.json</i> (as described
+        by the manual). It will contain your auth config:
+    <pre>
+        <code>
+{
+	"auths": {
+		"registry.gitlab.com": {
+			"auth": "..."
+		}
+	}
+}
+        </code>
+    </pre>
+    </p>
+    <p>
+        Now copy that file over to the server and register it in k8s with the following command:
+    <pre>
+        <code>
+kubectl create secret generic regcred \
+    --from-file=.dockerconfigjson=auth.json \
+    --type=kubernetes.io/dockerconfigjson
+
+        </code>
+    </pre>
+    </p>
+    <p>
+        Once you have created you can list by kubectl get secret:
+    <pre>
+        <code>
+NAME     TYPE                                  DATA   AGE
+regcred  kubernetes.io/dockerconfigjson        1      53s
+        </code>
+    </pre>
+    </p>
