check_openmanage

-A plugin for Nagios which checks the hardware health of Dell PowerEdge(11G, 12G and 13G) servers.

- It uses OMSA, running on the monitored system

Building Multi-container Architecture

Introducing Docker Compose

- a tool for defining and running multi-container Docker applications

- A single command creates and start all the services from your configuration

- Multiple isolated environments on a single host

- Preserve volume data when containers are created

- Only recreate containers that have changed

- Variables and moving a composition between environments

- Multiple isolated environments on a single host
