How to write a Puppet script Linux

I need puppet to execute a script that is inside an installed app. In addition I need to run only if it detects an older version of the and is not on a certain server and then install the new version. The particular task you seem to be trying to perform with your Exec duplicates standard behavior of the Package resource Just search for puppet using your package manager of choice. For example, on Ubuntu 10.04 you'd want puppet and puppet-common for the managed systems, and puppetmaster for the central server (if you have multiple systems) - tasks - sql_linux.sh - sql_linux.json - sql_windows.ps1 - sql_windows.json - sql.json puppet-agent: Present if the target has the Puppet agent package installed. To convert an existing script to a task, you can either write a task that wraps the script, or you can add logic in your script to check for parameters in environment. If you are managing a cloud of 1,000 virtual servers that are identical or differ in very predictable ways, this approach is not optimized for that case (and you should write an article for the next issue of Linux Journal). This approach is based around the ideas outlined in the excellent book Puppet 3 Beginners Guide by John Arundel. The basic.

The Puppet exec resource allows users to run commands and scripts on nodes. This can be used with bash on Linux, but with the PowerShell provider, it can run PowerShell on Windows and Linux nodes as well. There are a few important parameters to use when writing an exec resource with PowerShell. These are command, onlyif, returns and unless In this document we describe an installation of Puppet configuration manager on a Ubuntu Linux 14.04 Trusty Tahr. The installation will be followed by a simple puppet manifest example to make sure that installation was successful and puppet ready to use as standalone deployment In the first part of this tutorial, we showed how to use Vagrant to automate and manage local virtual machines for a software development environment. We defined a simple Vagrantfile to specify certain attributes for a VM to run a simple web app, and got it running using Vagrant's command line tools. In this part [

Each script argument entered at the command line has a default variable name. The first argument after the script name is assigned to the variable $1, the second argument to $2, and so on. This is a simple script displays information about a user to understand about script shell argument Apart from default file permissions in linux, there are three types of special permissions in LINUX. 1) Set User ID/SetUID i.e. SUID (Can be set on files and directories) 2) Set Group ID/SetGID i.e. SGID (Can be set on files and directories YAML - Basics - Now that you have an idea about YAML and its features, let us learn its basics with syntax and other operations.

We will go through the steps of installation in different Linux distributions, the most popular ones, in the next small tutorial. Install Ansible on Centos/RedHat system They always wanted to automate these tasks, so as to get more time to work on other projects or learn new concepts and scripting languages. Tasks can be automated by writing scripts, but in companies with a larger network, scripts don't come in handy. This is where Puppet comes to the rescue as with the help of Puppet one can

Puppet Forge is a catalogue of modules created by Puppet, our partners, and community that helps IT ops practitioners supercharge and simplify their automation processes. With step-by-step guides and tutorials, Puppet Forge provides a platform for you to grow your skills with Puppet, whatever your current level
  2. Preparing Preparing and Running Make. To prepare to use make, you must write a file called the makefile that describes the relationships among files in your program and provides commands for updating each file. In a program, typically, the executable file is updated from object files, which are in turn made by compiling source files
  3. If you are using macOS, the recommended installation is done via Python PIP: sudo pip install ansible. See the Ansible installation documentation for other distributions.. Working with Ansible Inventory. Ansible uses an INI-style file called an Inventory to track which servers it may manage. By default this file is located in /etc/ansible/hosts.In this article, I will use the Ansible Inventory.

Getting Started With Puppet Code: Manifests and Modules

  1. Built as cross-platform software, Puppet and Puppet Enterprise operate on multiple Unix-like systems (including Linux as well as Solaris, BSD, Mac OS X, AIX, HP-UX) and has Microsoft Windows support. [8] [9] Puppet itself is written in Ruby , while Facter is written in C++ , while Puppet Server and Puppet DB are written in Clojure
  2. The first step is to create the initial PowerShell script that is going to be used for custom script extensions. Our script will start small and simple; we will save the two lines below as VMExtension.ps1, and the script itself will create a registry key and a folder, and both will be AppX
  3. After your script is done working with the object, you use ConvertTo-JSON to give it the correct format. For the above object, this would look like this. Add the body. Now you can pass that JSON object in Invoke-RestMethod. In the case of the API we are testing here, this is the code you would run (change the parameters to your own version)
  4. Write yourself a shell script called n. Put this in it: With many Linux systems this will be enough to have a file /var/log/user.log opened and appended to, with others you may need to define a handling for that facility and log level (or, whichever facility you choose - the local0 to local7 facilities are usually free to assign to things.
  5. In my experience, Linux is easier to configure with Puppet (my servers are configured from top to bottom with it). Windows is a bit harder; PowerShell and PowerShell DSC help a lot, but sometimes I have to either use GPOs, or configure some apps and services manually because they are not designed to be managed by config. management tools or don.
  6. imize complexity, the solution was developed on Ansible, in conjunction with common Linux tools such as YUM, Bash scripts and SSH keys. No agent software installation or additional security infrastructure was required, thus the customer incurred zero appreciable cost for the technology
  7. I presume you are aware of the wc command for counting number of lines.We can use the same wc command with ls command to count the number of files in a directory.. This task seems simple but could soon turn slightly complex based on your need and definition of counting files

The above recipe contains a simple 'file' resource which creates a text file called test and puts in the content This is a test file on the system desktop. If you are familiar with writing Chef for Linux, you will see how they have kept the 'file' resource the same for both platforms. (This is one of the advantages I observed. All software on a Linux system is divided into packages that can be installed, uninstalled, upgraded, queried, and verified.

Debian Squeeze is moving to a dependency-based ordering of init scripts rather than numbering the scripts sequentially.

If more than 32 computer names are passed, PowerShell will queue the surplus computers until the script completes in one of the first 32 PSSessions I am building the project in a shell script build.sh.
