.deploy_repos(yum_path, origin_server, destination_server, dryrun = false) ⇒ Object

Deprecated.

this command is exactly as awful as you think it is. – Ryan McKern 12/2015

Parameters:

  • yum_path (String) —

    path for rpm repos on local and remote filesystem

  • origin_server (String) —

    remote host to start the rsync from

  • destination_server (String) —

    remote host to send rsynced content to

  • dryrun (Boolean) (defaults to: false) —

    whether or not to use ‘–dry-run’

def deploy_repos(yum_path, origin_server, destination_server, dryrun = false)

  Pkg::Util::Net.remote_execute(origin_server, rsync_command)
end

.generate_repo_configs(source = "repos", target = "repo_configs", signed = false) ⇒ Object

Generate yum configuration files that point to the repositories created on the distribution server with packages created from the current source repo commit. There is one for each dist/version that is packaged (e.g. el5, el6, etc). Files are created in pkg/repo_configs/rpm and are named pl-$project-$sha.conf, and can be placed in /etc/yum.repos.d to enable clients to install these packages.

Deprecated.

this command will die a painful death when we are able to sit down with Operations and refactor our distribution infra. At a minimum, it should be refactored alongside its Debian counterpart into something modestly more generic.

  • Ryan McKern 11/2015

Returns an rsync command that can be executed on a remote host to copy local content from that host to a remote node.

Parameters:

  • origin_path (String) —

    path for RPM repos on local filesystem

  • destination_path (String) —

    path for RPM repos on remote filesystem

  • destination (String) —

    remote host to send rsynced content to. If nil will copy locally

  • dryrun (Boolean) (defaults to: false) —

    whether or not to use ‘–dry-run’

Returns:

  • (String) —

    an rsync command that can be executed on a remote host to copy local content from that host to a remote node.
