Baking in the cloud with packer and puppet

Packer is software that allows you to create machine images for multiple platforms from a single template configuration. It uses builders to create images for platforms like AWS, VirtualBox, Docker etc. and provisioners can be used to configure the images. Packer provides benefits like consistency between development and production environments, and ease of sharing and reuse of images.

This document summarizes an Ansible and AWS meetup. It discusses using Ansible to provision and configure AWS resources like EC2 instances, security groups, ELBs, and more through idempotent playbooks. Key points covered include Ansible's agentless architecture, dynamic AWS inventory plugin, core modules like ec2 and cloudformation, templates, roles for reuse, and examples of provisioning playbooks that launch instances and apply configurations. It also briefly mentions NetflixOSS projects that use Ansible like Aminator for AMIs and Asgard for provisioning.

This document provides an introduction to Ansible, describing it as a simple and lightweight automation tool that can be used to execute one-time tasks, perform system administration tasks, and configure servers and routers. It discusses Ansible's key features including being written in Python, being open source, and being easy to install and use. It also provides information on installing and configuring Ansible on various operating systems as well as how to use ad-hoc commands and playbooks with Ansible.

Blue/Green deployments have been an important, if rarely implemented, technique in the Continuous Delivery playbook for years. Their aim is simple: provision, deploy, test — and optionally roll-back — your application before it's served to the public. Betterment's deployment architecture takes a similar, but more straightforward approach, accomplishing the important goals sought out by Blue/Green practitioners. Dubbed 'Cyan' (a mixture of Blue/Green), Betterment uses Ansible to provision new instances, push the latest artifacts to them, and ensure that they're healthy before marking them ready for production. All this ensures fast, stable, zero-downtime rollout with minimal human interaction. We'll discuss Betterment's philosophical approach to shipping new code and then dive into the nitty-gritty Ansible that powers the whole thing.

Jeff Geerling, author of Ansible for DevOps, demonstrates basic Ansible usage on the Dramble, a cluster of six Raspberry Pi 2 computers. This presentation was delivered on July 8, 2015, at the Ansible St. Louis meetup, at Riot Games in Clayton, MO.

This document provides an overview of Ansible, an open source tool for configuration management and application deployment. It discusses how Ansible aims to simplify infrastructure automation tasks through a model-driven approach without requiring developers to learn DevOps tools. Key points: - Ansible uses YAML playbooks to declaratively define server configurations and deployments in an idempotent and scalable way. - It provides ad-hoc command execution and setup facts gathering via SSH. Playbooks can target groups of servers to orchestrate complex multi-server tasks. - Variables, templates, conditionals allow playbooks to customize configurations for different environments. Plugins support integration with cloud, monitoring, messaging tools. - Ansible aims to reduce complexity compared

Anas Tarsha presented on using Ansible for network automation. Ansible is an open source automation tool that is agentless and uses simple YAML files called playbooks to execute tasks sequentially. It can be used to generate device configurations, push configurations, collect running configs, upgrade devices, and more. Ansible modules run Python code directly on network devices to perform tasks. The demo showed using Ansible modules like ping, ios_command, and junos_command to execute show commands and change the hostname on both IOS and Junos devices. Additional resources were provided to learn more about using Ansible for network automation.

Ansible is an agentless configuration management and provisioning tool that is easy to use and secure. It uses an inventory file to define hosts and groups, and facts to gather information about hosts. Playbooks are written in YAML format to define tasks like provisioning, deploying applications, and configuration using modules. Playbooks can include roles and tasks. Ansible has over 250 modules for various tasks like packaging, source control, cloud services, and operating system functions. Additional tools include Vault for encrypting variables and Galaxy for sharing roles.

- Ansible 2 includes an architecture overhaul, new YAML parsing engine, and 100% backwards compatibility for playbooks. It introduces task blocks for error handling and dynamic includes. Execution strategies allow running tasks linearly or in parallel. Many new modules were added. - Galaxy 2 provides better metrics, role management, and Travis CI integration. It allows importing roles from organizations and individuals. The ansible-galaxy CLI was improved with features like role scaffolding and authentication.

Introduces Ansible as DevOps favorite choice for Configuration Management and Server Provisioning. Enables audience to get started with using Ansible. Developed in Python which only needs YAML syntax knowledge to automate using this tool.

Andrew Hamilton presented on using Ansible for deploying to cloud environments. He discussed that Ansible was chosen to provide a simple and repeatable way to build services and deploy them to configured environments. It allows deploying to multiple languages and cloud platforms. Ansible uses a simple execution model and YAML files. Its key advantages include being agentless over SSH, supporting dynamic inventories, and having modules for common tasks. Hamilton provided tips for using Ansible effectively in cloud environments, such as using dynamic inventories, separating variables, and testing changes thoroughly.

This document contains information about the sys/net/sec admin Yashar Esmaildokht, including their contact information and websites. It then provides a brief overview of the open-source automation tool Ansible, describing its main features and uses for configuration management, application deployment, and cloud provisioning. Requirements and versions of Ansible are listed. The document concludes with examples of Ansible concepts including playbooks, tasks, modules, variables, and host inventory organization.

Everyone knows it's a Good Idea™ to use a configuration management system (e.g. Puppet, Chef) to manage your Drupal infrastructure. But many people (myself included) have run into a wall of #wtfmoments when trying to learn the vagaries of traditional CM systems and their vendor-specific syntaxes. In 2012, Ansible was released, enabling normal human beings to manage their servers with an easy, but powerful, CM system that uses YAML (just like Drupal 8!) to define configuration and Jinja2 (very much like Twig!) for templates. Not only that, but Ansible is also an incredibly simple and very flexible Drupal deployment and continuous delivery tool. Learn how you can use Ansible to manage your infrastructure—including local development environments—and stop letting servers and deployments get in the way of development.
