Puppet training is available as "online live training" or "onsite live training". Resource references identify a specific Puppet resource by its type and title. Puppet’s strength is in reusable code. This can be used to run a configuration management tool, bootstrap into a cluster, etc. exe ), Puppet will use the PATHEXT environment variable to resolve the appropriate binary. The long name of a module is formatted as <username>-<modulename>. # and subscribing to that one resource. Example of cron resource: See the filebucket resource type for more details.

If a given resource is already in the desired state, Puppet performs no actions. It's generally better to write resources in Puppet, as resources created with create_resource are difficult to read and troubleshoot. Classes are named blocks of Puppet code that are stored in modules and applied later when they are invoked by name. The remote-exec provisioner invokes a script on a remote resource after it is created. Additionally, some resources like exec will support attributes that work like a conditional, but only accept a command output as condition. newtype (:yumgroup) do @doc = "Manage Yum groups A typical rule will look like this: yumgroup { 'Development tools': ensure => present, } " ensurable newparam (:name) do isnamevar desc 'The name of the group' end end.

For example, to generate metadata for your production environment, run: puppet generate types --environment. I think that the simplest solution is to have the lifecycle of the 7-Zip package managed by exec resources rather than as package resources. 2. You can add classes to a node’s catalog by either declaring them in your manifests or assigning them from an external node classifier (ENC). The changes parameter gets passed a hash of change requests, keyed by the resource's name. Like “if” statements, case statements choose one of several blocks of arbitrary Puppet code to execute. msiexec /qn /norestart /i puppet-agent-<VERSION>-x64. If necessary, changes the system to enforce the desired state. Exec resources do not work that way. ) A caution: There’s a widespread tendency to use collections of execs to manage resources that aren’t covered by an existing resource type. 0. ) (See the notes on refreshing below.
