This document outlines the curriculum for a 4-week Red Hat OpenStack 17 study group. Week 4 focuses on deploying the overcloud and troubleshooting. The agenda includes creating an NFS server, preparing template files, deploying the overcloud, and previewing the next session. The template files define roles, networks, ports, and services for the overcloud nodes. Deploying the overcloud uses these templates to install OpenStack services onto the nodes from the repository containers.
[Open infra] how to calculate the cloud system operating rateNalee Jang
油
This document provides information on how to calculate the cloud system operating rate, including:
- It discusses OpenStack and Kubernetes, and how to find an efficient virtualization ratio for OpenStack by calculating the number of virtual machines that can be created based on hardware specifications and flavor types.
- It also covers how to calculate the cloud operating ratio by considering core functions like OpenStack live migration, necessary core items, and finding the ratio based on hardware and workload.
OpenStack services can be containerized to provide a more lightweight and portable deployment option compared to virtual machines. The document discusses how OpenStack services like Nova, Neutron, Cinder etc. run as individual containers that share the host operating system and can be configured by modifying files in a shared directory. Logs and operations like start/stop/restart can also be managed from the host through the container IDs. Overall, containerization allows OpenStack deployments to benefit from advantages like agility, density and simplified operations.
[Red Hat] OpenStack Automation with AnsibleNalee Jang
油
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 the OpenStack Korea User Group, which was created in February 2011. It holds seminars and events such as the OpenStack Days Korea conference every February and an OpenStack Birthday Party every July. It has over 4,700 members and holds a technical seminar once a month. The group has a homepage at openstack.or.kr and a Facebook group. Upcoming events include the 3rd OpenStack Days Korea conference in February 2016.
1. The document discusses how OpenStack can be used to build private and hybrid clouds for enterprises using open source technology free from vendor lock-in.
2. It provides examples of how OpenStack can enable continuous software delivery, cloud-enable applications, and provide IT as a service while reducing reliance on proprietary virtualization.
3. Asdtech offers turnkey OpenStack services including consultancy, cloud setup, custom development, migration, support and training to help enterprises orchestrate their existing infrastructure or build new clouds.
- The document discusses OpenStack, an open source cloud computing platform. It describes the current version, components, architecture, installation methods, and how to configure DevStack using a localrc file.
- A demo is provided of building a private cloud using DevStack on Ubuntu, configuring Nova, networking, and virtual machines.
- In conclusion, it claims that anyone can learn OpenStack in just two days by setting goals and following the instructions.
