OpenStack Basic to Advanced Installation and Administration

Explore OpenStack's major components, including the Horizon dashboard and Keystone identity service for token-based authentication, plus Neutron networking, Cinder storage, Glance images, Swift object storage, and Ceilometer telemetry.

Explore the OpenStack architecture with Keystone authentication, Horizon UI, and Glance image storage. Learn about Swift object storage, virtual machines (instances), and Neutron networking with Heat, Ironic, and Sahara.

Explore deployment topologies for a controller and compute nodes, detailing on-node services and agents, storage backends such as LVM or distributed storage, and neutron networking for VM connectivity.

Plan and design a three-node OpenStack deployment, detailing controller, network, and compute nodes, with emphasis on management network isolation, internet access, and VM networking.

Prepare the controller, network, and compute nodes, configure management and external networks, update hosts files, verify connectivity, and disable network manager and firewall to enable openstack installation.

Plan, create, and configure partitions and volumes for Swift and Cinder in OpenStack, using LVM on separate disks to provision block storage and object storage.

Create and customize the PackStack response file on the controller, generating a default file and editing it for passwords, IPs, networking, and Horizon SSL settings.

Set up trust from the controller to the network and compute nodes, run the OpenStack installation, and monitor logs to complete the controller, network, and compute node installation.

Perform post installation configuration to enable networking, create a flat public network with a subnet on the controller, reconfigure IPs, restart services, and verify external connectivity via Horizon.

Validate the OpenStack environment after installation by configuring networks, creating a router and subnets, provisioning a test image and VM, and confirming external connectivity with a floating IP.

Explore the Horizon user interface for OpenStack administration, managing instances, images, networks, volumes, and flavors. Understand project and admin perspectives, Keystone authentication, and API access through domain, users, and credentials.

Learn to create tenant networks with private subnets, connect virtual machines to internal and public networks, and configure gateways and floating IPs for internet connectivity.

Explore how the horizon dashboard and openstack command-line interface authenticate with keystone to obtain a token, then coordinate nova, glance, neutron, and cinder to boot a VM.

Explore the virtual machine life cycle in OpenStack, from building to active, suspended, soft deleted, and deleted states, and how transitions occur via the user interface.

Optimize OpenStack deployment by tuning bare metal and hypervisor configurations, creating flavors with memory and provisioning settings, and enabling Keystone memcache to improve Horizon performance.

Configure and validate OpenStack firewall rules with iptables, ensuring correct rule order, established connections, and proper reject handling using sample configurations for neutron tunneling and api exposure.

Extend OpenStack by adding a compute node: reuse the prior answers file, exclude existing hosts, set up trust and IPs, disable firewall, then register and verify via the Horizon console.

Add a storage node to an OpenStack cluster by configuring cinder volumes with LVM-based tender volumes, creating the cinder volume group, installing and enabling cinder services, and verifying in Horizon.

Explore how to use the OpenStack command line interface to list Neutron agents, servers, volumes, users, and images, and to use openstack --help for available options.
