Hello,
I am trying to define CFEngine policy so that I can issue cf-runagent from
policy server to activate UpdateClass on remote clients. Inside the
UpdateClass, it will first shutdown application process, then pull binary from
policy server, then start the process. Here is what I did.
$cat vsrv.cf
bundle agent OnHost
{
vars:
"u_policyhost" string => "172.16.13.123";
reports:
cfengine::
"$(sys.fqhost) is ready to update VSRV configuration";
methods:
BinUpdate::
"vsrv" usebundle => UpdateWorkFlow;
}
bundle agent UpdateWorkFlow
{
reports:
windows::
"I am inside UpdateWorkFlow bundle";
processes:
"sleep"
signals => { "term","kill" },
classes => if_repaired("PullFiles");
#reports:
# PullFiles::
# "I am inside PullFiles section";
PullFiles::
files:
"/data/vsrv/."
comment => "Update Application Binary from CFEngine Repository
Server",
create => "true",
depth_search => u_recurse("inf"),
perms => u_workdir_perms("0755"),
copy_from => remote_cp("/data/vsrv","$(u_policyhost)"); # line
with problem,even I change it to "policyhost", still report hostname is not
defined
}
In my promises.cf
$cat promises.cf
body common control {
any::
bundlesequence => { @(g.bundlesequence) };
any::
inputs => {
"update.cf",
"cfengine_stdlib.cf",
"classes.cf",
"/var/cfengine/masterfiles/cf-execd.cf",
"/var/cfengine/masterfiles/cf-serverd.cf",
"cf-report.cf",
"cleanup.cf",
"$(g.sitesfiles)/vsrv.cf"
};
output_prefix => "cf3--";
}
# global vars
bundle common g {
vars:
"workdir" string => "/var/cfengine";
"masterfiles" string => "$(workdir)/masterfiles";
"binaryfiles" string => "$(workdir)/bin";
"inputfiles" string => "$(workdir)/inputs";
"sitesfiles" string => "$(workdir)/masterfiles/sites";
"policyhost" string => "172.16.13.123";
"bundlesequence" slist => { "update", "executor", "server","cleanup",
"OnHost" };
## "bundlesequence" slist => { "update", "executor", "server","cleanup"
};
}
body runagent control {
hosts => { "127.0.0.1", "10.127.247.0/24", "10.127.248.0/24" };
}
cf-promise doesn't report error. When I run cf-agent, it doesn't copy files
from policy server and error in debug message is as following:
#cf-agent -DBinUpdate -v
......
cf3--> Copy file /data/vsrv/. from /data/vsrv check
cf3--> Unable to lookup hostname ($(policyhost)) or cfengine service: hostname
nor servname provided, or not known
cf3--> Unable to lookup hostname ($(policyhost)) or cfengine service: hostname
nor servname provided, or not known
cf3--> No existing connection to $(policyhost) is established...
Why it ignores the local defined variable?
Thanks,
