How to run a command on every node in a Docker Swarm cluster
Docker Swarm is a great way to deploy Docker Containers on AWS or Azure, both of which are supported cloud providers for Docker Community Edition (CE) and Enterprise Edition (EE).
A common admin task can be needing to run a command on all nodes on a cluster, either for monitoring or when debugging problems.
Executing Containers on all nodes in a cluster is easy, and the docker stats command lets you easily view the memory, CPU, network and IO usage of all Containers on an individual node.
