“Infrastructure As Code”
Some Samples
package { "apache2":
ensure => latest
}
service { "apache2":
ensure => running,
require => Package["apache2"],
subscribe => File[httpdconf],
}
Some Samples
package "apache2" do
package_name node[:apache][:package]
action :install
end
template "/etc/www/configures-apache.conf" do
notifies :restart, "service[apache2]”
end
service “apache2”
