 SSH in to the master node of the Docker Swarm cluster allocated to running containerized custom applicatins and beats. Clone this repo and change directory as per the instructions in the previous section
 
 Execute the following commands to deploy filebeat and metricbeat:
-  * `export ELASTIC_VERSION=6.4.0`
+  * `export ELASTIC_VERSION=6.4.3`
   * `docker network create --driver overlay elastic`
   * Edit "filebeat-docker-compose.yml" file. Change environment variables for Kibana and Elasticseaerch hosts
   * `docker stack deploy --compose-file filebeat-docker-compose.yml filebeat`  _(Filebeat starts as a global service on all docker swarm nodes. It is only configured to picks up container logs for all services at '`/var/lib/docker/containers/*/*.log`' (container stdout and stderr logs) and forward thtem to Elasticsearch. These logs will then be available under filebeat index in Kibana. You will need to add additional configurations for other log locations.
