In this chapter, we went through the typical Swarm administration procedures and options. After showing how to add managers and workers to the cluster, we explained, in detail, how to update clusters and node properties, how to check the Swarm health and we encountered Shipyard and Portainer as UIs. After this we focussed on infrastructure, it's now time to use our Swarms. We'll turn the key and put in motion some real application in the next chapter, by creating real services and tasks.
