playboook syntax?

I still have some problems with the yaml syntax, or something is broken in the parsing (which seems less likely).

[root@se1ts00x andreasda]# ansible-playbook playbook-tc2-resolver.yaml -k

Hi,

the error message is a bit misleading, your error is actually on line 5,
you missed a “:” after the “name” attribute. Here is the corrected version
of your yaml:

Many thanks! I have been staring at that yaml example on the gihub page and still I did not see that missing colon.

Oddly, I get these errors, even though the templating works just fine, since I can see it when I run "ansible -m command -a 'ls -l /tmp/resolv.conf'".

failed: [frostdw01.tc2] => copy src=/var/tmp/ansible.jWg694/source dest=/tmp/resolv.conf => {"changed": true, "failed": true, "md5sum": "42f278b0052ab986d21f12a1b2b5f7a5", "msg": "", "parsed": false}

stderr: [frostdw01.tc2] => Traceback (most recent call last):

    debug("current secontext is %s" % ':'.join(cur_context))

The debug line should definitely be removed then.

This is 0.3 or 0.4 (devel)?

That is 0.3.1 which I guess mean I should try 0.4 to see if it differ. I will update as soon as the new rpm is ouyt, since this is on a RHEL 6 machine. (Yeah, I have way too many differing machines in my server park...)

Ah, I had a git clone on that machine already. Yes, 0.4 works fine.
