The main goal is to provide a new implementation for the outdated Dialog Editor in the ManageIQ Admin and Operations User Interface while keeping in touch with modern web 2.0 righ client interfaces. Its current implementation is done in the interpreted programming language Ruby and requires evaluation on the server, that is generally time consuming, because of the need to exchange the data between user and server after almost every user’s interaction with the editor, and this forces the user to spend an uncomfortably long amount of time in the editor. The work on this bachelor thesis is done in collaboration with the Red Hat company, specificaly with the CloudForms and the UX Design team. The goal was reached by using the AngularJS JavaScript framework and several light- weight JavaScript libraries that will be described later in the document and the Patternfly UI framework, developed by Red Hat UX Design team. 1.2 Outline In this thesis there will be an analysis of the implementation and familiarization with every part related to the implementation itself. The ManageIQ project will be described at the beginning of this document in Chapter2. In Chapter3 there will be an analysis of the current status of the Dialog Editor. In Chapter4 I will describe how I designed the new version of the Dialog Editor. Used technologies for the implementation will be described in Chapter5. Explanation of the new Dialog Editor implementation will be in the Chapter6 and its effectivity and the users comfort will be presented in Chapter7. The results of the work will be summarized in Chapter8. 3 Chapter 2 ManageIQ ManageIQ is a management and automation platform that gives administrators the possi- bility to simplify control of their virtual, private, and hybrid cloud infrastructures. Many cloud based projects, like Openstack, Amazon EC2, Google Compute Engine or Microsoft Azure are supported by ManageIQ and that allows administrators to manage the diverse environments by one tool. It can automatically discover these environments wherever they are running and bring them all under one management roof. [3] ManageIQ is an open source community-driven project implemented in Ruby on Rails. It is developed since 2006, when ManageIQ, Inc. was founded as a startup. In late 2012 ManageIQ was acquired by Red Hat to be used as the basis for the Red Hat CloudForms hybrid cloud management platform, and has been open-sourced in June 2014 [7]. At the time of open-sourcing ManageIQ, the dual-license GPL and Apache License had to be used, but all the time the intention was to be single-licensed under the Apache License exclusively. This step was finaly achieved in March 2016 and was announced with an explanation ofthe choice on the ManageIQ project site 1 [1]. All the future plans of the ManageIQ community are described in the collaborative organization tool Trello 2 and can be discussed in many ways, mostly through IRC or discussion forums. A part of ManageIQ is a standalone interface called the Self Service User Interface that was introduced in Red Hat CloudForms 4.0 in December 2015 3. It is a portal allowing end users to manage their own services in a simpler interface than ManageIQ itself [2]. In the ManageIQ Admin and Operations User Interface the user can specify a service dialog that is used at the moment of the ordering of a service. Also another possible usage of the service dialog is for service automation. For such dialogs we need to have a Dialog Editor in ManageIQ Self Service User Interface, comfortable and easy to use for end users. Development of the ManageIQ Self Service User Interface is taking place in its own repository, because the whole interface is a 100% REST API driven JavaScript application. The source code for the ManageIQ Self Service User Interface can be found on the web-based Git repository hosting service GitHub 4. The reason for mentioning the Self Service User Interface in this thesis is that this standalone interface is where the new Dialog Editor will be used. 1https://manageiq.org/ 2https://trello.com 3http://cloudformsblog.redhat.com/2015/11/08/red-hat-cloudforms-4-0-public-beta-2/ 4https://github.com/ManageIQ/manageiq-ui-self_service 4 Chapter 3 Analysis of the current status The initial step to implementation was an investigation of the current implementation. There was a need to find answers for some major questions related to the implementation, such as: “What is the Service Dialog?”, “What does the Service Dialog consist of?” or “What are the required preferences for the Dialog?”. 3.1 Service Dialog In the ManageIQ interface, Service Dialogs can be found under the Automate ! Customiza- tion tab, and there under accordion with the label Service Dialogs. Service Dialogs can be used in several situations. The most common, when user wants to provision 1 a service. The dialog in its final form is basically an HTML form that is used to take input fromthe user. This input is then passed to Automation methods. Creating a new dialog can be divided into eight basic steps: 1. Navigate to the previously mentioned tab Automate ! Customization. 2. Select the accordion with the label Service Dialog. 3. From the toolbar select the Configuration ! Add a new Dialog option. 4. Fill in the information for the Dialog. 5. Fill in the information for a Tab (or more Tabs). 6. Fill in the information for a Box (or more Boxes). 7. Add and configure Elements in the Boxes. 8. Save the dialog. Every dialog has at least one tab that has been assigned a Description and a Label. The user can also choose whether the form should have a Submit and Cancel button, as you can see in Figure 3.1. After adding and filling in all the required information for a new tab, the user canadd a box that will be included under the tab. The same information needs to be provided for the box. 1obtain cloud service ordered from a cloud service catalog 5 A part of ManageIQ database scheme that de- scribes tables where the dialog content is stored can be seen in Figure 3.2.

  • Leveraging Containers and Openstack
    Leveraging Containers and OpenStack A Comprehensive Review Introduction Imagine that you are tasked to build an entire private cloud infrastructure from the ground up. You have a limited budget, a small but dedicated team, and are asked to pull off a miracle. A few years ago, you’d build an infrastructure with applications running in virtual machines, with some bare-metal machines for legacy applications. As infrastructure has evolved, virtual machines (VMs) enabled greater levels of efficiency and agility, but VMs alone don’t completely meet the needs of an agile approach to application deployment. They continue to serve as a foundation for running many applications, but increasingly, developers are looking toward the emerging trend of containers for leading-edge application development and deployment because containers offer increased levels of agility and efficiency. Container technologies like Docker and Kubernetes are becoming the leading standards for building containerized applications. They help free organizations from complexity that limits development agility. Containers, container infrastructure, and container deployment technologies have proven themselves to be very powerful abstractions that can be applied to a number of different use cases. Using something like Kubernetes, an organization can deliver a cloud that solely uses containers for application delivery. But a leading-edge private cloud isn’t just about containers, and containers aren’t appropriate for all workloads and use cases. Today, most private cloud infrastructures need to encompass bare-metal machines for managing infrastructure, virtual machines for legacy applications, and containers for newer applications. The ability to support, manage and orchestrate all three approaches is the key to operational efficiency.

  • Ansible 2.2 Documentation Release 2.4
    Ansible 2.2 Documentation Release 2.4 Ansible, Inc October 06, 2017 Contents 1 About Ansible 1 i ii CHAPTER 1 About Ansible Welcome to the Ansible documentation! Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates. Ansible’s main goals are simplicity and ease-of-use. It also has a strong focus on security and reliability, featuring a minimum of moving parts, usage of OpenSSH for transport (with other transports and pull modes as alternatives), and a language that is designed around auditability by humans–even those not familiar with the program. We believe simplicity is relevant to all sizes of environments, so we design for busy users of all types: developers, sysadmins, release engineers, IT managers, and everyone in between. Ansible is appropriate for managing all envi- ronments, from small setups with a handful of instances to enterprise environments with many thousands of instances. Ansible manages machines in an agent-less manner. There is never a question of how to upgrade remote daemons or the problem of not being able to manage systems because daemons are uninstalled. Because OpenSSH is one of the most peer-reviewed open source components, security exposure is greatly reduced. Ansible is decentralized–it relies on your existing OS credentials to control access to remote machines. If needed, Ansible can easily connect with Kerberos, LDAP, and other centralized authentication management systems. This documentation covers the current released version of Ansible (2.3) and also some development version features (2.4).
