Chef

Chef – instalacja klienta i dodanie go przez użycie knife

Instalacja klienta jest prosta: wykonujemy jeden skrypt, który ściągnie i zainstaluje wszystko: 

[root@server1 ~]# curl -L https://www.opscode.com/chef/install.sh | sudo bash

WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING

You are installing an omnibus package without a version pin.  If you are installing
on production servers via an automated process this is DANGEROUS and you will
be upgraded without warning on new releases, even to new major releases.
Letting the version float is only appropriate in desktop, test, development or
CI/CD environments.

Thank you for installing Chef!

Gdy mamy skonfigurowany knife, dodanie kolejnego klienta nie stanowi problemu:
