Hi,
I have a custom provider that seems to run ok in isolation by itself.
In addition, puppet does not complain at all when it runs. However,
when I ensure => installed a package the desired package is never
installed.
There are a few differences between this and something such as the gem
provider, most importantly, I couldn't find anyway to get the provider
to run as a different user without doing direct system call.
Here's the provider
Puppet::Type.type(:package).provide :npm, :parent =>
Puppet::Provider::Package do
desc "node.js package management with npm"
commands :npm_cmd => "/home/node/opt/bin/npm"
raise Puppet::Error, "The npm provider can only be used as root" if
Process.euid != 0
def self.npm_list(hash)
begin
s = `sudo -u node sh -c \"export PATH=/home/node/opt/bin:$
{PATH}; npm ls installed\"`
list = s.split("\n").collect do |set|
if npm_hash = npm_split(set)
npm_hash[:provider] = :npm
if npm_hash[:name] == hash[:justme]
npm_hash
else
nil
end
else
nil
end
end.compact
rescue Puppet::ExecutionFailure => detail
raise Puppet::Error, "Could not list npm packages: #{detail}"
end
list.shift
end
def self.npm_split(desc)
split_desc = desc.split(/ /)
installed = split_desc[0]
name = installed.split(/@/)[0]
version = installed.split(/@/)[1]
if (name.nil? || version.nil?)
Puppet.warning "Could not match #{desc}"
nil
else
return {
:name => name,
:ensure => version
}
end
end
def install
output = `sudo -u node sh -c \"export PATH=/home/node/opt/bin:$
{PATH}; npm install http-console\"`
if output =~ /npm not ok/
raise Puppet::ExecutionFailure, "Failed to install
#{resource[:name]}"
end
end
def uninstall
output = `sudo -u node sh -c \"export PATH=/home/node/opt/bin:$
{PATH}; npm uninstall #{resource[:name]}\"`
if output =~ /npm not ok/
raise Puppet::ExecutionFailure, "Failed to uninstall
#{resource[:name]}"
end
end
def query
version = nil
self.class.npm_list(:justme => resource[:name])
end
end
Does anybody have an idea what's going wrong?
The other problem I'm having is that I have to manually copy the
provider to puppet lib from the module lib.
Thanks.
