2. In this session
This year, We enhance the start of the new IDC, I have
changed each time the application by mcollective's
puppet plugin from starting up this operation of the
puppet agent daemon.
• Why changed, What I wanted to
• What came to be, and what can no longer be
• Challenges for the future

Over 200 Servers

6. Why changed,
What I wanted to
Purpose of using the puppet has changed.
• As well as configuration management, to deploy
management.
• For testing, change the settings only some servers.

7. Configuration/Deploy Management
• Manifests to be taken from github.
• No automatic apply, using mco puppet agent.
• Mcollective/Deploy Management explained in the
session by Ms. Kondo.

8. puppet/mcollective/rabbitmq
(normal operation)
puppet
master
dlv server #1
rabbitmq
dlv server #2 dlv server #3 dlv server #4
mco puppet -I /.*/ runonce
puppet agent --test --color=false
me !
me !
me !me !

9. puppet/mcollective/rabbitmq
(single host)
puppet
master
server #1
rabbitmq
server #2 server #3 server #4
mco puppet -I /#4/ runonce
puppet agent --test --color=false
not me not me
not me
me !

10. What came to be,
and what can no longer be
• Apply specific manifests (branch) to a server using
mcollective (mco puppet agent).
• Apply Manifest to the server is no longer automatic.
• Need to ensure that do not change the settings
on the server, and check changes automatically.

11. Challenges for the future
• Version control of the catalog that have been
applied…
• Plugin agent result of puppet
• mco puppet status can’t catch error in catalog
compile. (syslog can do)

12. And others..
• Now, we can deliver dlv servers at instant power on.
• It use only cobbler and puppet, no use of
mcollective.
• If you have interested in, talk later.
