OpenInfra Days Poland 2019 slides

1. Project Onboarding Poland OpenInfra Days 2019

2. “Airship is a collection of loosely coupled, but
interoperable, open source tools that
declaratively automate cloud provisioning.”
Airship Overview
• Orchestration: Batteries included
• Singular Deployment Method
• Predictable Upgrades
• Repeatable Multi-site Deployments
• Resiliency
Motivations

3. Airship Projects
Pegleg Document Aggregation
Shipyard Front door to Airship; orchestrates activities
Drydock Declarative bare-metal provisioning
Promenade Declarative HA Kubernetes installer
Deckhand Document management and layering
Armada Declarative management of complex Helm deployments
Divingbell Declarative bare-metal configuration management
Treasuremap Reference YAML manifests and CICD

Step 1:
Prepare for Deployment
Pegleg fetches YAML documents from Git
Pegleg feeds them to Shipyard, which forwards them to Deckhand for storage
Deckhand saves secrets to Barbican, other data to PostgreSQL
Airship components validate the YAML documents

5. Airship Control Plane Node(s)
Pegleg
MaaS
PromenadeDrydock
Shipyard
Armada
Deckhand
Shipyard invokes Drydock to perform bare metal provisioning
Drydock drives MaaS, which provisions the node(s)
Drydock retrieves a boot action Kubernetes join script from Promenade
The provisioned node joins the Kubernetes cluster upon reboot
