Puppet supports most of the conditional structures you can find with traditional programming languages, like if/else and case statements. 04; In Puppet, the combined configuration to be applied to a host is called a catalog, and the process of applying it is called a run. 4+, your original code would be possible. As a result, you cannot write a single pattern that matches all the files you want to remove. If set to false, file content won't be backed up. However, we need to execute the semanage command to manage port settings. require means that the the resource passed to require must be applied before the calling resource. 5.

Providers implement the same resource type on different kinds of systems. When writing Puppet manifests to manage Windows systems, there are two extra issues to take into account when writing file paths: directory separators and file system redirection. There is always only one resource being applied, the next one will always wait for the previous to finish. Each resource describes the desired state for some aspect of a system, like a specific service or package. /usr/local/bin/pip install nltk. It can build a catalog from the manifest (e.

If a given resource is already in the desired state, Puppet performs no actions. In other words, if you use standard Puppet relationships to ensure that tooling is managed prior to classes or resources that use the deferred functions using that tooling, then it will operate as expected and the function will execute properly. Technically, you could use: exec { "root_bashrc": command => "bash -c 'source /root/. Description. Parameters. Resource definition: the type. This is the documentation for Puppet's built-in resource types and providers.

In simple cases, "applying" an Exec involves running its command, and the success or failure of the resource is based on the command's exit status. Some packages (Git is a notable example) will change their display names with every version released. Puppet variables are evaluated and used (only) as part of the catalog-building process, so their values are needed before any Exec runs. Resource types. To specify that a resource must.
