Hi. I'm hoping that someone can help me with a simple example. We are
trying to use puppet to update a server binary to a group of machines.
Here's pseudocode for what I'm trying:
if (server_binary has changed) {
1) stop the old server
2) overwrite the old server binary by
fetching the new server binary from puppet
3) start the new server
}
Here's the puppet manifest I wrote to handle this, but it isn't working
properly. It is not working as intended, and is 1) downloading the new
binary and then 2) stopping the server, which screws up our data. I've
been looking through the documentation, and it isn't clear which
permutation of before, require, subscribe, or notify is necessary to
accomplish this. Hope someone can enlighten me. - Mat
file { "/usr/local/sbin/server_binary":
source => "puppet:///files/server_binary",
require => Exec["stop-server"],
before => Exec["start-server"]
}
# Stops the server
exec { "/usr/local/sbin/stop-server":
alias => "stop-server",
refreshonly => true
}
# Starts the server
exec { "/usr/local/sbin/start-server":
alias => "start-server",
refreshonly => true
}
