确保木偶在配置文件中存在

Question

After this existing block

prefix 2a03:2267:4e6f:7264:0000:0000:0000:0000/64
 {
 };

I want to add a new block, if it doesn't exist already:

prefix fdda:fee6:0187:0000:0000:0000:0000:0000/64
 {
 };

in /etc/radvd.conf ( not at the end of the file)

and then /etc/init.d/radvd restart

How do I manage this with puppet?

Answer 1

Install

puppet module install puppetlabs-stdlib

Then create a script addblock.pp:

file_line { "ensure $line in /etc/radvd.conf":
    path  => '/etc/radvd.conf',
    line  => "prefix fdda:fee6:0187:0000:0000:0000:0000:0000/64\n{\n};",
}


exec { "restart":
  command => '/etc/init.d/radvd restart',
  provider => shell,
  require => File_line["ensure $line in /etc/radvd.conf"],
}
