Puppet 7. That is, if there is a change in 2 or more files, then the exec resource have to be called only once. Resources are the fundamental unit for modeling system configurations. All parameters are optional. The Puppet “exec” resource allows users to run commands and scripts on nodes. To install packages into a directory controlled by a non-root user, you can either use an exec to unzip a tarball or use a recursive file resource to copy a directory into place. A stringified regular expression. -> (ordering arrow; a hyphen and a greater-than sign) — Applies the resource on the left before the resource on the right. Puppet variables are evaluated and used (only) as part of the catalog-building process, so their values are needed before any Exec runs. When using exec resources with the powershell provider, the command parameter must be single-quoted to prevent Puppet from interpolating $(. Puppet Unscheduling all events on Stage [main] I have an issue with Puppet and want to understand it better. However, unfortunately, there is no way to make file_line match over multiple lines and replace with new content. This can be used with bash on Linux, but with the PowerShell provider, it can run PowerShell on Windows and Linux nodes as well. Deploy it with Puppet, and yes, do use an exec resource if you want Puppet to trigger the update. ) (See the notes on refreshing below. Implemented via types and provider instead of exec resource. exe -NoProfile -NoLogo -NonInteractive -Command "& {set-service Spooler -Status Running. (Just tested similar configuration with Puppet 2.

If you do need to do it via say the exec resource, then @16c7x's statement is correct. Resources. Wrapping the service resource into an if block like I did with the exec resource doesn't work either since the service resource does multiple things: It starts the service if it isn't. Since Puppet uses the same exec resource type on both *nix and Windows systems, there are a few Windows-specific caveats to keep in mind. ) (See the notes on refreshing below. Then, you can install the Nuget package via the package resource in Puppet. filter by arbitrary "foo_update" # tag and relate it to all Package resources Exec. [1]A key feature of Puppet is its idempotency: the ability to repeatedly apply a manifest to guarantee a desired resource state on a system, with the same results every time. The exec has refreshonly => true, which allows Puppet to run the command only when some other resource is changed.

Puppet offers expert training in methods that work best for you. Returns the smallest Integer greater or equal to the argument. on whatever server is used to compile the catalog, NOT on the host where the catalog is actually applied. In the minimal example above we first give the command a. (Puppet automatically creates a local filebucket named puppet if one doesn’t already exist. Puppet doesn't work that way - The earlier exec will have it's onlyif condition evaluated, not execute a command, and the file resource will happen after the exec, regardless of it executing the command. In most cases, managing sudo on your agents involves. If you really want to use puppet apply, intead of the more comment puppet agent, you can either :. In this example, the ntp package must be installed before the ntp. Returns the smallest Integer greater or equal to the argument. All parameters are optional. puppet apply -e "exec { '/usr/bin/false': }" Notice: Compiled catalog for alexs-macbook-pro. Therefore, they should not be set outside of site. Now you have a basic Puppet setup. Running Powershell command directly using Puppet exec resource. 1 and drop Puppet 4 #84 (bastelfreak) Implemented enhancements: Features request: SCL repos #66;. The most important point that I was trying to convey to you in my previous message was that Puppet does not use a mechanism anything like that to set up the environment for the Exec's commands. They are subtypes of the fairly abstract Resource data type. It is purely sequential. The optional :parent argument should be the name of a parent class. This is a very old issue with Puppet that has no good solution as of now. refreshonly => true, } The important bit here is the ~> . log, depending on the flag used) to a Support ticket, making sure to remove any sensitive information. The following example shows you how to create resources in Puppet using the low-level types and provider method. The most important point that I was trying to convey to you in my previous message was that Puppet does not use a mechanism anything like that to set up the environment for the Exec's commands. ) (See the notes on refreshing below. In addition to the resource types included with Puppet, you can install custom resource types as modules from the Forge. The default search pattern is the name of the service, but you can specify it with the pattern attribute. Calling puppet defined resource with multiple parameters, multiple times. The resources type fits basic needs, by allowing to purge all resources not managed by Puppet.

When validating multiple issues per file are reported up to the settings of max_error, and max_warnings. The exec type provides a simple way to run those commands via puppet (on the puppet client, not the master) and harness them in your modelling, whether as a dependency of another resource, an easy way to accomplish something puppet doesn't yet provide or as part of a gradual migration. A manifest is a file containing Puppet configuration language that describes how resources should be configured. ). Match expressions. What you present has no chance of working anything like how you intend. File contents can be managed directly with the content attribute, or downloaded from a remote source using the source attribute; the latter can. This effectively means that if any resource or class forms a relationship with the container, it will form the same relationship. There are a large number of built-in resource types and the Puppet 5. The exec resource type executes external commands on the client. The Exec doesn't execute at all and I have noticed that a little later in the /var/log/messages there is. Then, you can install the Nuget package via the package resource in Puppet. I want to execute an exec resource if a service is not found, skip the exec resource if the service is found.

An "if" statement takes a Boolean condition and an arbitrary block of Puppet code, and executes the code block only if the condition is true. Exec to be notified if desired. But either way the trailing exit statement in the command will return a non-zero exit code if that happens. ) The state managed by an exec resource represents whether the specified command needs to be executed during the catalog run.

That is mediated, where desired, by the resource's unless, onlyif, and / or creates parameters, as described in that resource type's documentation. All parameters are optional. There is a sort-of-related question where the user does this. If a given resource is already in the desired state, Puppet performs no actions.
