Ansible is an IT automation tool that allows users to easily automate routine system administration tasks. It uses YAML files called playbooks to configure, deploy, and manage applications and infrastructure. Ansible Core is the command line version of Ansible that includes tools like ansible and ansible-playbook. Ansible Tower provides a web-based interface and additional features like job templates, workflows, dashboards, and APIs for advanced automation.

Here are some recommendations for completing this code:
- JButton b = new JButton("Click Me");
- parent.add(b);
- b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// button click logic
}
});
This creates a basic JButton, adds it to the parent panel, and registers an anonymous listener to handle button clicks.
When flexibility met simplicity: the friendship of OpenStack and AnsibleMajor Hayden
Ansible is an open source tool that automates IT infrastructure and reduces complexity. It can manage OpenStack deployments and operations through flexible automation while keeping OpenStack's flexibility. The presentation showed how Ansible can help OpenStack operators, administrators and deployers automate tasks like launching instances, managing projects and users, and deploying OpenStack itself. It concluded by recommending ways to get started with Ansible like reading the documentation, joining communities, and finding open source projects that use Ansible with OpenStack.
This document summarizes how Ansible is used at Glogster. It discusses that Ansible was chosen over other tools like Puppet for its simplicity. Ansible is used to deploy RPM packages, manage services, and disable/enable monitoring across environments. It is also used with Jenkins for deployments and isolated tests. Ansible is ideal for security patches, package updates, and new server provisioning via roles, tags, and replacing tools like cssh/pssh. The document encourages keeping everything in Git, avoiding redundant logic, using tags, and treating Ansible as both tests and documentation for servers. It also discusses desires like using Docker, wrapping infrastructure in a single playbook, using dynamic inventory, and keeping facts in cache.
[Red Hat] OpenStack Automation with AnsibleNalee Jang
This document discusses using Ansible to automate OpenStack tasks. It begins with an introduction to the speaker and their background working with OpenStack, CloudForms, and Ansible. It then discusses the iterative nature of infrastructure work and how automation can help. The document introduces Ansible and how it can be used for provisioning, configuration management, security, and application deployment. It provides an overview of how to set up an environment for OpenStack automation with Ansible, including designing playbooks and tasks. Specific examples are given for automating image registration, network creation, SSH key generation, security group configuration, flavor creation, and instance deployment. The presentation emphasizes that many of the required playbooks already exist online and can be reused.
The document discusses IBM's involvement with open source software over time, from early contributions to Linux and Apache projects in the late 1990s and 2000s to current strategies. It provides examples of key open source projects IBM has led or contributed to substantially, such as Eclipse, Linux, Apache Web server, and POWER architecture. The document also outlines the benefits of open source development practices like transparency, peer review, and scalability.

Voice Enabled Home Automation using Amazon EchoIRJET Journal
This document summarizes a student project that uses Amazon Echo and a Raspberry Pi to enable voice control of home appliances. The system allows non-smart home devices to be controlled using voice commands to an Amazon Echo. When a command is given to turn a device on or off, the Echo communicates with a Raspberry Pi over WiFi using a Node.js program. The Pi then uses a Python program and relays to physically control the appliances. The design uses a publisher-subscriber model for communication and Amazon Web Services for infrastructure. The project aims to make basic home automation more affordable and accessible.
Ansible is an open-source configuration management tool that uses an agentless architecture with SSH or WinRM to install and run modules temporarily on nodes. It has both open source and enterprise versions. Playbooks are used to automate tasks and modules implement specific provisioning functions. While Ansible supports Windows, there are some challenges like PowerShell's double-hop CredSSP limitation and YAML syntax sensitivity.
OpenNebulaConf 2014 - OpenNebula as alternative to commercial virtualization ...OpenNebula Project
This document discusses Runtastic's transition from using rented hardware to implementing an Opennebula virtualization solution. It describes Runtastic's infrastructure needs, alternatives considered like VMware and OpenStack, and why Opennebula was chosen. The current productive Opennebula setup at Runtastic is outlined, including 30 Cisco nodes, NFS storage, and over 250 VMs. Future plans with Opennebula like adding nodes and contextualization are also mentioned.
OpenNebula Conf 2014 | OpenNebula as alternative to commercial virtualization...NETWAYS
It wasn’t more then 4 months between the first getting in touch with Opennebula and our productive Opennebula cluster beeing fired up. It was a quick decision that turned our to be the absolute right one. Since a little more than a year we are on our evolving way with Opennebula.
So what have we been looking for and why did we end up with Opennebula? How does our setup look like in the moment and what are our future plans with Opennebula? Learnings from a year with Opennebula.

Cloudfoundry + K8S : Prendre le meilleur des deux mondesErwan Bornier
This document summarizes a presentation about using CloudFoundry and Kubernetes together. It discusses how CloudFoundry BOSH can provide release engineering, deployment, and lifecycle management for Kubernetes clusters through a project called CF Container Runtime (CFCR). This allows using Kubernetes for container orchestration while leveraging BOSH capabilities. It also presents Pivotal's approach to providing a unified platform for developing, deploying and managing applications on CloudFoundry and Kubernetes through shared services, security, networking and other capabilities.
Knative is a platform for deploying and managing serverless workloads on Kubernetes. It provides a simpler way for developers to deploy and run stateless applications and functions. Knative is comprised of three main components - Serving, Build and Eventing. Serving provides a scale-to-zero compute runtime leveraging Istio for traffic routing. Build enables container image building from source. Eventing offers event consumption and publishing through channels and subscriptions. Riff is designed for running functions in response to events and extends Knative by providing additional capabilities like event sources, buses and invokers. Pivotal supports serverless workloads through products like Pivotal Application Service, Pivotal Container Service and Pivotal Function

Top Java IDE keyboard shortcuts for Eclipse, IntelliJIDEA, NetBeans (report p...ZeroTurnaround
This document summarizes and compares keyboard shortcuts across three popular Java IDEs: Eclipse, IntelliJ IDEA, and NetBeans. It divides common actions into eight categories such as search, file navigation, and code completion. While the default shortcuts differ between IDEs, they can all be customized. The document aims to help developers learn shortcuts and features of their IDE or potential alternatives.

Griffon is an open source desktop application development platform for the Java Virtual Machine (JVM) that is inspired by Grails. It uses conventions over configurations and allows for polyglot programming. Griffon provides commands to create, run, test, and package applications and plugins. It supports common deployment formats and UI toolkits.
Cloud hybridation leveraging on Docker 1.12Ludovic Piot
Since many apps are not about just a single container, this talk discusses the ability and benefits of creating an hybrid Docker cluster capacity leveraging on Linux+Windows OS and x86+ARM architectures.
Moreover, the Docker nodes composing this cloud will be hosted across several providers (local DC, cloud vendors such as Azure or AWS), in order to face various scenarios (cloud migration, elasticity…).
The pillars of DevOps are Culture, Automation, Measurement and Sharing. Docker is a rare tool at enables DevOps through all 4 pillars. These slides take a look at how Docker can affect each pillar in your organization through a Lean lens.
