Let’s think about Bigger Picture !!!
Cluster of Nodes
Management Tools
Time to build Microservice Architecture to reduce the
deployment time and simplify the management tool

Running OMSA & SNMP inside Docker
$docker run --privileged -d -p 161:161/udp -p 1311:1311
--restart=always --net=host
-v /lib/modules/`uname -r`:/lib/modules/`uname -r`
--name=omsa82-snmpd
jdelaros1/openmanage-snmp
RHEL7 SLES12 12.04/14.04
Debian 7/8
CentOS7
Platform tested
OMSA + SNMP

7. Dell World Executive Summit
Running Nagios + Dell Monitoring Tool inside Docker
$docker run -d -p –net=host ajeetraina/nagios-docker
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

Work in progress..
- Using Docker Swarm to manage multiple Dell Monitoring Containers
- Implementing Out-of-Band Dell Monitoring Container
- Running Dell OpenManage Essential in a container
- Using Puppet for pushing Dell Monitoring Containers to huge Infrastructure
- Containerizing HPC tools

Docker is not magic. You create magic around Docker.
