standalone_self_upgrade.cf

Table of Contents

$(sys.inputdir)/standalone_self_upgrade.cf is an independent policy set entry like promises.cf and update.cf. The policy is executed by an independent agent executed from the update.cf entry when the class trigger_upgrade is defined and the host is not seen to be running the desired version of the agent. The policy is designed for use with Enterprise packages, but can be customized for use with community packages.

main

Prototype: main

Description: This bundle drives the self upgrade. It actuates the appropriate bundles to download binaries to the hub for serving to clients, caching the software to remote clients, and managing the version of cfengine installed on non hubs.

Implementation:

bundle agent main
{
  classes:

      "policy_server_dat_unstable"
        expression => isnewerthan( "$(sys.workdir)/policy_server.dat", "$(sys.workdir)/outputs" ),
        comment => "If $(sys.workdir)/policy_server.dat is newer than the
                    outputs directory, it can indicate that the current agent
                    execution is a result of bootstrap. For stability we want to
                    skip upgrades during bootstrap. The outputs directory should
                    be newer than the policy_server.dat on the next agent run
                    and allow upgrade then.";
