5 likes5,470 views
- 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.

Continuous Testing with Molecule, Ansible, and GitHub Actions
Continuous Testing with Molecule, Ansible, and GitHub ActionsJeff Geerling The presentation uses an example and explanation from Chapter 13 in my book, Ansible for DevOps: https://www.ansiblefordevops.com
Make sure you never commit a broken playbook using Molecule, Ansible, and GitHub Actions. Jeff Geerling discusses his CI workflows using GitHub Actions to manage hundreds of Ansible-based projects, including playbooks, roles, collections, and even Kubernetes Operators. Learn how Molecule makes developing and testing Ansible content easier, and how you can integrate it with GitHub Actions—or any other CI environment—for easy Ansible CI.

DevOps for Humans - Ansible for Drupal Deployment Victory!
DevOps for Humans - Ansible for Drupal Deployment Victory!Jeff Geerling 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.
What's New in v2 - AnsibleFest London 2015
What's New in v2 - AnsibleFest London 2015jimi-c This document discusses version 2 (V2) of Ansible, which refactors portions of Ansible's core executor engine to address technical debt. Key changes in V2 include improved error messages, new block and strategy execution plugins, execution-time evaluation of included tasks, and better object-oriented design. The goal is to improve testability and make it easier to add new features without breaking existing functionality. V2 can be tested now and will become the default in March 2015, while Ansible 1.9 will be the last major release using the original code.
Cyansible
CyansibleAlan Norton 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.

Ansible and AWS
Ansible and AWSPeter Sankauskas 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.
Ansible + Drupal: A Fortuitous DevOps Match
Ansible + Drupal: A Fortuitous DevOps MatchJeff Geerling This document discusses using Ansible to automate the deployment of Drupal 8 on a cluster of Raspberry Pis, called the #Dramble. It begins with an introduction to Ansible and how it can be used to solve problems with growing infrastructure and complex Drupal deployments. It then demonstrates how to define servers in Ansible inventory, run ad-hoc commands, and build playbooks to provision servers and deploy Drupal 8. Benchmarks show the #Dramble can handle over 2,000 requests per second when caching is enabled, but only 14 requests per second without caching. More opportunities for improving Drupal 8 performance on the #Dramble are discussed.

Network Automation with Ansible
Network Automation with AnsibleAnas 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.

How Ansible Makes Automation Easy
How Ansible Makes Automation EasyPeter Sankauskas - Ansible is an automation tool that allows users to automate installation, configuration, deployment and provisioning tasks. It uses YAML files called playbooks to execute tasks in order.
- Playbooks can automate a wide range of tasks including installing and configuring services, deploying code, provisioning infrastructure, and creating machine images.
- Ansible makes automation easy through features like easy to read playbooks, thousands of reusable modules, extensive documentation, and flexibility to run against different operating systems and environments.

Chasing AMI - Building Amazon machine images with Puppet, Packer and Jenkins
Chasing AMI - Building Amazon machine images with Puppet, Packer and JenkinsTomas Doran Using puppet when configuring EC2 machines seems a natural fit. However bringing up new machines from a community image with puppet is not trivial and can be slow, and so not useful for auto-scaling.
The cloud also offers a solution to ongoing server maintenance, allowing you to launch fresh instances whenever you upgrade your applications (Immutable or Phoenix servers). However to predictably succeed, you need to freeze the puppet code alongside the application version for deployment.
The solution to these issues is generating custom machine images (AMIs) with your software inlined. This talk will cover Yelp's use of a Packer, Jenkins and Puppet for generating AMIs. This will include how we deal with issues like bootstrapping, getting canonical information about a machine's environment and cluster state at launch time, as well as supporting immutable/phoenix servers in combination with more traditional long lived servers inside our hybrid cloud infrastructure.

Answer: See this presentation to find out! Jeff Geerling is the author of Ansible for DevOps and a Technical Architect at Acquia, who has worked on many large and small scale Drupal websites.
High Performance Drupal
High Performance DrupalJeff Geerling "Drupal is always so fast!" ... said no one, ever.
Drupal has a reputation as being a slow CMS, but that reputation is undeserved; there are many small things that impact a Drupal site's performance in sometimes substantial ways. This session will highlight many 'quick wins' that will get your site performing like a champ in no time!
Then we'll take a demonstration site that has many elements of real-world 'slow' Drupal sites, show how to do a quick performance evaluation/triage, and change the site from loading in 4-5 seconds to loading in less than a second, and maxing out at 2 requests per second to a speedy 4,000+ requests per second!
The session will also discuss the importance of a plan, benchmarking, and assumptions when you do performance work on your own Drupal site.

Ansible presentation
Ansible presentationJohn Lynch 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

OSCamp 2019 | #3 Ansible: Automated Tests of Ansible code with GitLab, Vagran...NETWAYS Ansible playbooks and roles are code and as any other code it should be tested automatically before it is applied in production environments. But unit tests are not as usefull for Ansible code. We need integrations tests with a fresh linux system everytime. We test with the triple-A concept:
• Arrange: boot one or more fresh linux VMs (Vagrant, Virtualbox)
• Act: apply Ansible code to test
• Assert: test state of the VMs with another Ansible playbook
More topics:
• Why testing the Ansible code too?
• How to test on every git commit?
• Troubles to create a testing environment
Testing Ansible
Testing AnsibleAnth Courtney - Ansible provides built-in modules and functionality for testing playbooks and roles, including syntax checking, validating idempotency, and asserting expected outcomes. Common approaches include testing against virtual environments and embedding functional tests within playbooks and roles.
- Tools like Molecule and Tox help standardize and automate testing Ansible roles across different environments and versions, and support continuous integration workflows. Following principles of testing outcomes over implementations and keeping tests focused helps ensure effective yet maintainable testing.

Ansible 202 - sysarmy
Ansible 202 - sysarmySebastian Montini Ansible is a simple yet powerful automation engine that uses YAML syntax. It is fast, efficient, and secure as it does not require agents or open ports on servers. Ansible uses inventory to list hosts and groups, modules to define units of work, facts to discover node details, and playbooks to define lists of plays and tasks. Playbooks can use tags to selectively run certain tasks. Roles help organize and reuse groups of tasks. Galaxy allows installing roles from online repositories. Variables precedence determines which value is used. Vault encrypts sensitive files.

Reuse, Reduce, Recycle in Serverless World
Reuse, Reduce, Recycle in Serverless WorldDmitri Zimine Slides for the talk at @ServerlessConf San Francisco 2018
Reuse is fundamental to any software development. Serverless development, however, still misses a coherent end-to-end resuability story. AWS Application Repository, Serverless Components from @goserverless, and LogicApps' Connectors are all the steps in the right direction. But we are still far away from npm/pip install developer's paradise. What is missing, and the what is path forward?
In this talk, I reflect on the current state of reusability in Serverless, share relevant learnings from establishing reusability in DevOps tools, and show a working code, a proof of concept for an open-source catalog of reusable Serverless functions. How exactly? We recycled StackStorm Exchange - a mature opensource action catalog - with a plugin to serverless framework. Come and see the details, and bring your ideas to discuss how we promote reusability in Serverless.

Maven: Managing Software Projects for Repeatable Results
Maven: Managing Software Projects for Repeatable ResultsSteve Keener Maven is a tool for managing Java-based software projects that provides a standard way to manage builds, documentation, dependencies, and project metadata. It simplifies common project tasks like compiling code, generating reports, and managing dependencies. Maven uses a Project Object Model (POM) file to store build settings and dependencies for a project. It maintains a central repository of dependencies to avoid duplicate copies of files. Maven builds can be configured to compile code, test it, package artifacts, and generate reports through a standardized process. Maven archetypes provide project templates to quickly generate new projects with common configurations.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.
Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...
Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...Ranjan Baisak As software complexity grows, traditional static analysis tools struggle to detect vulnerabilities with both precision and context—often triggering high false positive rates and developer fatigue. This article explores how Graph Neural Networks (GNNs), when applied to source code representations like Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs), and Data Flow Graphs (DFGs), can revolutionize vulnerability detection. We break down how GNNs model code semantics more effectively than flat token sequences, and how techniques like attention mechanisms, hybrid graph construction, and feedback loops significantly reduce false positives. With insights from real-world datasets and recent research, this guide shows how to build more reliable, proactive, and interpretable vulnerability detection systems using GNNs.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.

Ansible 2 and Ansible Galaxy 2
- 1. Ansible 2 Ansible Galaxy 2 Jeff Geerling (geerlingguy) Ansible St. Louis Meetup - 2016-03-09
- 3. Ansible 2 - Motivation • Architecture overhaul • New YAML parsing engine • 100% backwards compatibility (playbooks) • Ran out of Van Halen songs
- 5. Task Blocks --- - hosts: all tasks: - block: - name: Script to connect the app to a monitoring service. script: monitoring-connect.sh rescue: - name: This will only run in case of an error in the block. debug: msg="There was an error in the block." always: - name: This will always run no matter what. debug: msg="This always executes." when: ansible_os_family == 'RedHat' become: yes tags: ['monitoring', 'redhat']
- 6. (Actually) Helpful Errors $ ansible-playbook test.yml ERROR! Syntax Error while loading YAML. The error appears to have been in '/Users/jeff.geerling/test/test.yml': line 9, column 1, but may be elsewhere in the file depending on the exact syntax problem.
- 7. Dynamic Includes - include: test.yml with_items: - 1 - 2 - 3 when: runtime_variable_is_true
- 8. Execution Strategies • Built-in: • linear - standard one-by-one, wait for all hosts • free - hosts go as fast as they can
- 9. New Modules • More for OpenStack, AWS, VMware, Windows, etc • package module! • apk, bundler, expect, find, iptables, pear, puppet...
- 10. Variable Improvements • Settable with vars at play, block, role, task levels • Scoped to tasks contained within tasks: - block: - name: Script to connect the app to a monitoring service. script: monitoring-connect.sh rescue: - name: This will only run in case of an error in the block. debug: msg="There was an error in the block." vars: workspace: "/tmp"
- 11. Inventory • Added meta: refresh_inventory to force reload
- 12. Breaking Changes • Plugin API • Ansible API • Template code (doesn't turn bools/numbers into strings) • Empty/null variables (doesn't turn into strings)
- 13. More on Ansible 2 • Ansible 2.0 Launch (Ansible Blog) • Ansible 2.0 Changelog • Ansible 2.0 and Windows
- 14. Galaxy 2 - Motivation • Galaxy was more or less unchanged since launch in 2014. • Role maintainers had to do a lot of manual work. • Best practices started forming in the community (e.g. testing). • 'Organizations' weren't a thing; everything namespaced to individuals.
- 15. Better metrics • GitHub stars and watchers • Download counts • Travis test status built in
- 16. Better role import UX • Roles can be imported from Organizations or individual users on GitHub. Easy as clicking 'import' • To switch a role from username to organization, delete then import again
- 17. Better role management • Role management on Galaxy is much better
- 18. Travis CI Integration • Use Travis CI notification: to automatically notify Galaxy on role updates and new tags: 1. Add Travis token to your Galaxy role settings 2. Enable the repo in Travis CI 3. Add notification config to .travis.yml notifications: webhooks: https://galaxy.ansible.com/api/v1/notifications/
- 19. ansible-galaxy cli • Role scaffold (init) includes basic Travis integration • Better search, import, delete, setup and login
- 20. More on Galaxy 2 • Ansible Galaxy 2.0 Launches
