Hi Mark (and Jeff)
Firstly - thanks so much for this module. It's a nice example of
making hard things possible!
Now I seem to have stumbled on a bug but unfortunately not a fix.
* Distribution: Net::Amazon::EC2
* Version: 0.18
* Perl version:
This is perl 5, version 14, subversion 2 (v5.14.2) built for
i686-linux-gnu-thread-multi-64int
(with 53 registered patches, see perl -V for more detail)
* Operating System vendor and version (Find this by running the
command uname -a)
Linux ip-10-229-77-105 3.2.0-23-virtual #36-Ubuntu SMP Tue Apr 10
23:58:38 UTC 2012 i686 i686 i386 GNU/Linux
* Issue:
- When I call run_instances it's fine until I add the UserData
parameter. At this point I get the output below.
The encode_base64 output I'm using for the UserData parameter is
IyEvYmluL2Jhc2gKCnVzZXJtb2QgLXAgbXlGVExGQTJYdDMvNiBzdHVkZW50ICY+IC90bXAvdXNl
cm1vZC5vdXQKCg==
(is it a problem it contains a newline?)
It is generated with
my $user_data =
encode_base64(
'#!/bin/bash
usermod -p myFTLFA2Xt3/6 student &> /tmp/usermod.out
');
- When I paste the base64 userdata above into
https://console.aws.amazon.com when creating an instance, it works
fine.
Kind regards,
Andrew
