+  } else {

+  }
+}
+</code>
+/etc/docker/daemon.json
+<code>
+{
+  "log-driver": "syslog",
+  "log-opts":
+    {

+Restart rsyslog, the docker daemon and then all containers to switch to the new driver. Otherwise the docker daemon shows the following error message for the affected containers: "Configured log driver does not support reads, enabling local file cache for container logs".
