[SOLVED] firewall-cmd fails in cloud-init

Post by matobinder » 2015/04/17 18:40:10

So I'm trying to build some CentOS7 machines via OpenStack 5. I cannot get firewall-cmd to work from within the cloud-init file. The error seems to be more CentOS related than cloud-init. But here goes. I have a real simple cloud-init file. Basically this

..
runcmd:
- /bin/yum install firewalld -y
- /bin/systemctl enable firewalld
- /bin/systemctl start firewalld
- /bin/firewall-cmd --permanent --zone=public --add-port=12345/tcp

The first 3 commands work fine, but the firewall-cmd errors out with this message

"
cloud-init: ERROR:dbus.proxies:Introspect error on :1.9:/org/fedoraproject/FirewallD1/config: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
"

I did a bit of searching, and it sounds like in some cases this is because its not ran as root? I thought all cloud-init files ran as root. I really want to be able to configure cert ports while spinning up a lot of VMs.

If you do not receive a reply to your request, here in the forum, it might be best to ask for help on the main CentOS mailing list.

Good suggestion to post in the main forum, got an answer almost immediately. I just needed to use firewall-offline-cmd.

Here's a link to that thread, so if some one finds this one, they can see the other quickly.
