Hi,
I defined a method on a client, which can be activated by remote cf-runagent
on cfengine server as "cf-runagent -DBinUpdate -H ". Then it will kill
application process, pull new binary, then start application process. Here is
the bundle:
================================================
$cat -n vsrv.cf
1 #####################################################
2 # #
3 # configuration file for VSRV server #
4 # #
5 #####################################################
6 ##
7 ##
8 bundle agent OnHost
9 {
10 #vars:
11 # "policyhost" string => "172.16.13.123";
12
13
14 reports:
15 cfengine::
16 "$(sys.fqhost) is ready to update VSRV configuration";
17
18 methods:
19 BinUpdate::
20 "vsrv" usebundle => UpdateWorkFlow;
21
22 }
23
24 bundle agent UpdateWorkFlow
25 {
26 vars:
27 "policyhost" string => "172.16.13.123";
28
29 reports:
30 windows::
31 "I am inside UpdateWorkFlow bundle";
32
33 processes:
34 "sleep"
35 signals => { "term","kill" },
36 classes => if_repaired("PullFiles");
37
38 #reports:
39 # PullFiles::
40 # "I am inside PullFiles section";
41
42 PullFiles::
43 files:
44 "/data/vsrv/."
45 comment => "Update Application Binary from CFEngine Repo
sitory Server",
46 create => "true",
47 depth_search => u_recurse("inf"),
48 perms => u_workdir_perms("0755"),
49 copy_from => remote_cp("/data/vsrv","$(policyhost)");
50
51 }
52
================================================
If I define "policyhost" on line27, everything is working as expected. If I
define "policyhost" on line 11, it will show following errors:
=================================================
$cf-agent -DBinUpdate -v -K

=================================================
Per my understanding, promise types are executed in order -
vars,classes,methods,processes,commands,reports. Why I have to define variable
in the same bundle?
I also tried to define "policyhost" in common bundle with the same error. Here
is my promises.cf
==================================================
$ less promises.cf

body common control {
any::
bundlesequence => { @(g.bundlesequence) };

"update.cf",

"/var/cfengine/masterfiles/cf-serverd.cf",
"cf-report.cf",
"cleanup.cf",
"$(g.sitesfiles)/$(global.HostFunction).cf"
};
output_prefix => "cf3--";
}
# global vars
bundle common g {

"bundlesequence" slist => { "update", "executor", "server","cleanup", "O

## "bundlesequence" slist => { "update", "executor", "server","cleanup" }
;
}
body runagent control {
hosts => { "127.0.0.1", "10.127.247.0/24", "10.127.248.0/24" };
}
==================================================
What did I miss? Thanks in advance!
