+# Anatomy of a Pod
+
+- The containers inside a pod share the network namespace (`--net=container:<container_id>`)
+
+   => the one of the "pause" containers
+
+- This means that if the container "pause" is killed all other container are killed
+
+- This is the reason for this container to do nothing but being alive
+
+- Containers can contact other container port via `localhost`
+
+- Containers don't share filesystem except the volumes you want to mount on each of them
