Finally, as you make changes and new layers are added, you'll always have a top layer (think frosting) that is a writable layer. 2. Layered file system What makes this truly efficient is that Docker caches the layers the first time we build them. So, let's say that we have an image with Ubuntu and then add Apache and build the image. Next, we build MySQL with Ubuntu as the base. The second build will be much faster because the Ubuntu layer is already cached. 2, are already baked. We simply need to bake the pistachio (MySQL) layer, assemble, and add the icing (writable layer).

The replicas element defines the desired number of pods, the selector tells the controller which pods to watch, and finally, the template element defines a template to launch a new pod. The template section contains the same pieces we saw in our pod definition earlier. An important thing to note is that the selector values need to match the labels values specified in the pod template.
