configuration-management

Problem I have a set of client machines that are a part of an enterprise web application. Each machine runs identical software, which is a PyQT-based web client that connects to a server. This client software is updated regularly and I would like to have some configuration/provisioning tool that allows to have the same environment on each machine and hence provide easy deployment and configuration of the software onto each of the clients' machines. The problem is that I have tried to use Chef, but it takes a lot of effort to actually maintain Chef knowledge and skills (we do not have a

What is the basic difference between convergence and idempotence in Chef? Convergence and idempotence are not Chef-specific. They're generally attributed to configuration management theory, though have use in other fields, notably mathematics. Let's start with the more basic, idempotent. We're going to ignore the mathematic use of idempotent, and focus instead on what configuration management people mean when they talk about it. That is: "multiple applications of the same action do not have side effects on the system state." A simple example of an idempotent operation is mkdir -p : mkdir -p

In an Ansible role I generate the user's SSH key. After that I want to print it to the screen and pause so the user can copy and paste it somewhere else. So far I have something like this: - name: Generate SSH keys for vagrant user user: name=vagrant generate_ssh_key=yes ssh_key_bits=2048 - name: Show SSH public key command: /bin/cat $home_directory/.ssh/id_rsa.pub - name: Wait for user to copy SSH public key pause: prompt="Please add the SSH public key above to your GitHub account" The 'Show SSH public key' task completes but doesn't show the output. TASK: [Show SSH public key] **************

I am working on a product suite which has 4 products. Right now, all of the configuration data is either in the XML or properties files.This approach is not maintainable as we have to manage different configuration file for different environment(for e.g. Production, Development etc). So, what is the best way to handle configuration data? Also, can we modularize this into a separate module? So that all products can use this module. We don't want to use the property files. I am looking for a solution in which we can move all of the configuration specific code as a new configuration module and

I have been managing Subversion as an engineering document storage repository for my company. It is working fairly well, however I have a question about how MS Office 2007 formats are (should be) handled by Subversion. I'm looking at an Excel 2007 spreadsheet (extension .xlsx) in my working copy that Subversion has applied the svn:mime-type property application/octet-stream . This means that Subversion is treated it as binary, right? I was hoping that the new MS Office document formats would be stored efficiently by Subversion. My understanding is that a full copy of a binary file will be made
