I'm a very new to Puppet, but I cannot wrap my head around this simple problem: I want to define a resource that simply execute a sequence of scripts, one after the other, waiting for one's execution to finish before launching the next. The exec has refreshonly => true, which only allows Puppet to run the command when some other resource is changed. Resource reference or data type. You can get involved by fixing bugs, influencing new feature direction, publishing your modules, and engaging with the community to share knowledge and. You will seldom need to specify this — Puppet will usually discover the appropriate provider for your platform. Puppet is declarative - you tell it what state you want a system, and it goes and creates it. To complete our tour of the basic elements of a manifest, let's take a closer look at the resource types that you have already used, and some of the more import. Refresh: mount resources can respond to refresh events (via notify, subscribe, or the ~> arrow). You can classify nodes using an external node classifier (ENC), which is a script or application that tells Puppet which classes a node must have. Among them, notice (), info (), and debug () seem the. Chaining arrows forming relationships between three resources, using resource references. create_resource has it's own condition weather it will execute but it needs to be called every time just after the exec. If a given resource is already in the desired state, Puppet performs no actions. Puppet: Exec from class when Exec from another class is successful. Puppet will not automatically retrieve source files for you, and usually just passes the value of source to the package installation command. One thing that you can do (and I don't recommend) and that is not "puppet way" is following:Making Puppet exec work The exec resource from Puppet, the automation framework, is a mysterious beast. What worked was putting the definition in the class where I want to use some exec resources, but that is basically the same as defining the path for every exec. pp --ordering=random ). ” There is also a set of values whose data type is “data type. It is messy and not best practice though. ” These values represent the other data types. pp node 'puppet-agent' { include user include sudoers include exec } Run Puppet: Puppet uses the same exec resource type on both *nix and Windows systems, and there are a few Windows-specific best practices and tips to keep in mind. If you want to add variables to your commands' (quite sparse) environments then the environment parameter of the Exec resource is usually the most appropriate way to do it, but you cannot use command substitutions there. In this example, there is an array of command names to be used in each symlink’s path and target. ; Prevent Puppet from making changes, by setting the noop. This is especially useful when managing Windows systems, because. This tool is a part of the policycoreutils-python package, which is not installed on Red Hat Enterprise Linux systems by default. The RESOURCE_TYPE is how you tell Puppet the type of resource you’re declaring. user. Back to overview of ora_exec. exec { "initialize-footool": require => Package ["footool"] } file { "/etc/default/footool": before => Exec ["initialize-footool"] } read more like english than just requires on the exec.

It would be quicker (and dirtier) to use an Exec resource to run an appropriate command: exec { 'ensure correct file permissions': command => 'chmod 0644 $(/bin/grep file. Use per-resource default attributes when possible. 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. Puppet and Windows handle directory separators and line endings in files somewhat differently, so you must be aware of the differences when you are writing manifests to manage Windows systems. On an upgrade we are pushing a new tar-file to the puppet master and let puppet update the server. Providers. The exec has refreshonly => true, which only allows Puppet to run the command when some other resource is changed. Ordering follows from that, but so also. notify. do the exec only when notfied. Any command. If omitted, this attribute’s value defaults to the resource’s title. Some providers may also accept URLs or network drive paths. Providers.

However, we need to execute the semanage command to manage port settings. ) The state managed by an exec resource represents whether the specified command needs to be executed during the catalog run. If you do need to do it via say the exec resource, then @16c7x's statement is correct. A resource declaration is an expression that describes the desired state for a resource and tells Puppet to add it to the catalog. puppet apply -e "exec { '/usr/bin/false': }" Notice: Compiled catalog for alexs-macbook-pro. exec { "Change status and start-up of Win service": command => 'C:\Windows\System32\WindowsPowerShell\v1.

There's a generalizable form of this dependency that might be helpful in reducing the repetition of the require statement. group. approved. However, the problem with the exec is that it is not idempotent. The benefits over existing modules such as puppet-staging: Implemented via types and provider instead of exec resource.
