Puppet Hash Hiera

a "hash key" computation is provided automatically). A hiera_hash lookup works in the same way, only it gathers all matching values into a single hash and returns that hash. If the same key exists in multiple source hashes, Hiera will use the value from the highest-priority data source; it won’t recursively merge the values. Configure Hiera to provide these values in the next section. Puppet Bolt is an agentless multi-platform solution that allows you to get started with automation without the prerequisites of an agent or any Puppet knowledge. Hiera The trick is to structure your Hiera Data and use the same Fully Qualified Names in the keys. Modules making use of simple string data that has been retrieved from Hiera. YUM repositories. While Hiera is great in many ways, there are a few things it could do better. Puppet and nested hashes in hiera In Puppet, representing your data like a normal mortal would do leads you nowhere. Modules now contain Bolt Tasks that take action outside of a desired state managed by Puppet. But for those who know hiera well, and understand what bad data means, than read on. yaml with a hierarchy like this. The data and results are necessarily hashes, but just because your value is expected to be a hash does not mean you need or want hiera_hash(). Separating code and data can be tricky. HTTP backend for Hiera A puppet module to provide the ability to install and decrypt a gpg-encrypted file on the agent host. Anyway, so I took this as a starting point and started working on a Hiera based classifier for Puppet 4 - and by that I mean the very very latest Puppet 4, it uses a bunch of the things I blogged about recently and the end result is that the module is almost entirely built using the native Puppet 4 DSL. 比如certname=node1的节点在运行puppet agent --test时,puppetmaster就会去读取node1. It provides a command line tool hiera that we can use to interrogate direclty the Hiera data and functions to be used inside Puppet manifests: hiera() , hiera_array() , hiera_hash() , hiera_include() Hiera is installed by default with Puppet version 3 and is available as separated download on earlier version (Installation instructions).

One of the issues we encountered with puppet 4. 0 builtin hiera does. Use this lookup type only if the hash key has nested hashes. Используя стандартные функции Паппета, hiera(), hiera_array(), hiera_hash(), hiera_include() и create_resources(), как вы уже наверняка догадались, можно много чего напридумывать. The Puppet manifest is like a blueprint that maps the Hiera config to the machine configuration. This post tries to show you an idea on how to work with hashes in hiera. 7+ now integrates hiera into the same puppet gem. Understanding Advanced Puppet: Hiera, Iterations, Profiles & Resources If you've used Puppet, you probably know difficult is develop the modules needed for your requirements. Puppet is also fantastic for higher level application management—from simple tomcat/java apps to full Oracle and SQL servers. First, let’s cover what a YAML hash is. With that data separated from your Puppet code, you then can encrypt sensitive values, such as passwords and keys. Assumption:. The short answer is to use hiera whenever you expect to need a single lookup from a single part of your hierachy. When I say different data, I mean hiera tool returns an array of items collected throughout the hierarchy, while hiera_array() called from within a manifest returns an array of items from the very top level of hierarchy. pdf), Text File (. yaml vhosts: hostname: sitename:. At Puppet Labs, we’ve been busy over the last few months, working on overhauling our public modules to treat them as distinct pieces of software rather than less tested one-offs. Basically, `hiera_hash` and `hiera_array` with deep merge (using a global hiera. We use the Puppet DSL to grab a list of the "roles", then check each one to see if the requesting node is a member of it and include it if it is. For Example: Bob and Jill will have access to ALL hosts via root. To access a single member of an array or hash, use the name of the value followed by a dot (. The configuration file for the global layer is located, by default, in /hiera.

In Puppet 5, Puppet took the old hiera command and renamed it to puppet lookup along with other refinements. If the 'rpm_mon_base_pack' key appeared at multiple levels of your hierarchy, then the array returned by hiera_array () would contain the values from the other levels, too -- that's the main purpose of the funciton. It retrieves all of the (hash) values for a given key, then merges the hashes into a single hash. diff --git a/hieradata/common. Modules now contain Bolt Tasks that take action outside of a desired state managed by Puppet. This takes the opposite approach of the previous pull request, moving to using nil consistently instead of empty hashes and arrays consistently. GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

When hashes are merged (using the + operator), the keys in the constructed hash have the same order as in the original hashes, with the left hash keys ordered first, followed by any keys that appeared only in the hash on the right side of the merge. Bug #14509 hiera returns nil instead of empty hash if no parameters are set. While usually glueing hiera to puppet resources is not the most complex thing, I had a caveat: one particular hiera_hash had to be filtered and restructured and passed as a parameter for another Puppet resource. For customers new to configuration management with AWS OpsWorks for Puppet Enterprise (OWPE), a frequently-asked question is “How do I store sensitive data, such as database passwords, for use in my manifests?”. If the same key exists in multiple source hashes, Hiera will recursively merge hash or array values (with duplicate values removed from arrays). But you can't make it check if a hash (found in the hierarchy) contains (at least) all keys defined in default_hash. I put all of the server/role assignments into a hash in Hiera, and a scrap of Puppet code looks at this hash and pushes the custom fact as a file into any newly-added hosts. Puppet manifests contain the description of what to do with those values. codeDeploy 'production' puppet. I am iterating over many entries in a hiera hash, and wish to remove identical duplicate lines from hiera by setting defaults in the manifest (such as ensure, groups, managehome etc), and have the defaults overridden IF the duplicate key/value pair exists in hiera. 0 builtin hiera does. This takes the opposite approach of the previous pull request, moving to using nil consistently instead of empty hashes and arrays consistently. This is a huge win and really shows what can be done with the Data in Modules features and something that’s been impossible before. Then you can instruct puppet to perform a hiera lookup using a number of functions: hiera; hiera_array; hiera_hash. In this Puppet environment, users are listed in hiera in a hash. If the 'rpm_mon_base_pack' key appeared at multiple levels of your hierarchy, then the array returned by hiera_array () would contain the values from the other levels, too -- that's the main purpose of the funciton. Durch den grundsätzlichen anderen Aufbau von Windows im Vergleich zu Linux, MacOS X & Co. With Hiera, you can externalize your systems' configuration data and easily understand how those values are assigned to your servers. According to its self-reported version number, the Puppet Enterprise application running on the remote host is version prior to 2016. Hiera data is great for separating code and data.

Then on the second Puppet run, the host will have any role-specific Hiera settings / classes applied. Puppet uses Hiera to do two things: Store the configuration data in key-value pairs Look up what data a particular module needs for a given node during catalog compilation. Hiera 5’s custom backend system is much simpler than in earlier Hiera versions. Don't assign a hash with non-string keys to a resource attribute or class parameter, because Puppet cannot serialize non-string hash keys into the catalog. We'll see how to use the Puppet Forge to download existing modules, specifically the PuppetDB module.
