Hi,
Just a note on how we dealt with a little config management management ;-)
issue.
We were interested in a way to manage multiple versions of CFE client scripts
served from a single CFE server. I took the idea of using a
"policy_server.dat" file that identifies the server a client will contact and
added a file "policy_path.dat" that identifies the top path that the client
will fetch files from. This seemed like a handy way to allow some clients to
be configured from a development configuration while the production config goes
unchanged. We are also likely to use it to serve a frozen or tagged
configuration to some clients.
One the server, the client configs are stored below paths such as:
/var/cfengine/masterfiles
/var/cfengine/masterfiles-devel
/var/cfengine/masterfiles-frozen
Then in the update.cf the .dat files are read into variables:
vars:
"policy_server_dat"
comment => "IP of my policy host, read from file",
string => readfile("$(sys.workdir)/policy_server.dat",40);
"policy_path_dat"
comment => "Path to my config on policy host, read from file",
string => readfile("$(sys.workdir)/policy_path.dat",80);
We have defaults built into the update.cf if these files aren't read.
Remember to allow access to all needed paths in the server access_rules block.
