Subject: Template expansion with lists
Author: neilhwatson
Link to topic: https://cfengine.com/forum/read.php?3,23033,23033#msg-23033
It is possible to have a list expanded in a template? My attempts so far have
meet with failure:
# cat promises.cf
body common control {
bundlesequence => {
"main",
};
inputs => {
"cfengine_stdlib.cf",
};
host_licenses_paid => "50";
}
bundle agent main {
vars:
"time_servers" slist => {
"tick.example.com",
"tock.example.com",
"clock.example.com"
};
"other" string => "Other config option";
methods:
"any" usebundle => ntp_tmp_1("@(main.time_servers)","$(other)"),
handle => "main_methods_ntp_tmp_1",
comment => "call motd_tmp_44 bundle";
}
bundle agent ntp_tmp_1 (server, other){
vars:
"tmpfile" string => "/var/tmp/cf_templates/ntp.conf";
files:
"/etc/demo_ntp.conf"
perms => mog("0644","root","root"),
create => "true",
edit_defaults => empty,
edit_line => expand_template("$(tmpfile)");
reports:
cfengine_3::
"Server: $(server)";
}
# cat /var/tmp/cf_templates/ntp.conf
@{ntp_tmp_1.server}
@{server}
${server}
${ntp_tmp_1.server}
${ntp_tmp_1.other}
# cf-agent -IKf ./promises.cf
!! Unknown user $(user) in promise
R: Server: tick.example.com
R: Server: tock.example.com
R: Server: clock.example.com
# cat /etc/demo_ntp.conf
@{ntp_tmp_1.server}
@{server}
${server}
${ntp_tmp_1.server}
Other config option
I had hoped to see some attempt at expansion for the slist called server. Is
this even possible?
