AIRSHIP | A NEW OPEN INFRASTRUCTURE PROJECT FOR O P E N|SWhat T A C&KWhy: Airship Architecture: What The focus is a declarative platform to introduce Open. Stack on Kubernetes (OOK), and the lifecycle mgmt. of the resulting cloud, with the scale, speed, resiliency, flexibility & operational predictability demanded Why of Network Clouds. DECLARATIVE CONTAINER BASED Sites are declared using YAML, including both hard assets & soft assets. You manage the document and Airship implements it. ONE WORKFLOW Containers are the unit of software delivery for Airship. This allows progress from dev, to testing, and production with confidence. ARCHITECTURALLY FLEXIBLE One workflow that handles both initial deployments and future site updates with virtually no difference in interacting with the two Airship to manages our entire cloud platform, not just Open.

Appendix
THE AIRSHIP SUB PROJECTS Security Containerizati on Treasure Map: Divingbell: is the documentation project that outlines a reference architecture for automated cloud provisioning and management, leveraging the Airship interoperable opensource tools. is a lightweight solution for 1) Bare metal configuration management for a few very targeted use cases and 2) Bare metal package manager orchestration Shipyard: is the directed acyclic graph controller for Kubernetes and Open. Stack control plane life cycle management, and a component of the Undercloud Platform (UCP). Drydock: is a python REST orchestrator to translate a YAML host topology to a provisioned set of hosts and provide a set of postprovisioning instructions. 20 Quality Deckhand: is a storage service for YAML-based configuration documents, which are managed through version control and automatically validated. Deckhand provides users with a variety of different document types that describe complex configurations using the features listed below. © 2018 AT&T Intellectual Property. All Rights Reserved.

THE AIRSHIP SUB PROJECTS Armada: is a tool for managing multiple Helm charts with dependencies by centralizing all configurations in a single Armada YAML and providing life-cycle hooks for all Helm releases. Note: Armada is an enhancement to the helm client. Still using the helm tiller service, we deploy multiple charts with data-driven yamls. Promenade: is a tool for bootstrapping a resilient Kubernetes cluster and managing its life-cycle via Helm charts. Berth: is a deliberately minimalist VM runner for Kubernetes. Pegleg: Security Containerizati on Quality Open Source Projects that Airship Leverages/Integrates with: Open. Stack-Helm: is a Open. Stack project to provide a collection of Helm charts that simply, resiliently, and flexibly deploy Open. Stack and related services on Kubernetes Helm: is a tool for managing Kubernetes charts. Charts are packages of pre-configured Kubernetes resources. Kubernetes (K 8 s): is a open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. document aggregator providing early linting © 2018 AT&T Intellectual Property.
