Hi Adrian,
I'm not sure but I imagine by just trying to 'source' the profile within the
current puppet runtime the scope will be lost as it would be called within
an exec?
Obviously if you are not worried about running puppet multiple times you
might be able to source it in your 'prerun_command' script.
Otherwise I have one possible (albeit slightly hacky) option. Perhaps you
can drop to ruby to ensure you set the variable JAVA_HOME within the puppet
runtime. Let me give you an example I set-up on my machine:
/tmp/var.sh:
#!/bin/bash
echo $JAVA_HOME > /tmp/java_path
test.pp:
$dummy = inline_template("<% ENV['JAVA_HOME'] = '/opt/java_1.6.0_20' %>")
exec {"a":
command => "/tmp/var.sh",
}
notice(inline_template("<%= ENV['JAVA_HOME'] %>"))
And to run it:
$ puppet test.pp
notice: Scope(Class[main]): /opt/java_1.6.0_20
notice: /Stage[main]//Exec[a]/returns: executed successfully
$ cat /tmp/java_path
/opt/java_1.6.0_20
$
This shows that the environment variable is available at the scope when ruby
does an exec (the exec resource) and when you try to grab the variable
inline later on. Hopefully the gem provider should see this, but you'll have
to make sure the inline_template runs before the gem does its work. Putting
it in a class (like your "java" puppet class or something) and doing a
require on the class may solve this.
Of course there is probably a nicer less complicated way of doing this :-).
ken.
