Seaworthy: Production-grade Airship

Airship Seaworthy is a multi-node site deployment reference and continuous integration pipeline.

The site manifests are available at site/airship-seaworthy.

Pipeline

Airship Seaworthy pipeline automates deployment flow documented in Site Authoring and Deployment Guide.

The pipeline is implemented as Jenkins Pipeline (Groovy), see code for the pipeline at Jenkinsfile.

Versions

The manifest overrides (versions.yaml) are setup to deploy OpenStack Ocata.

The versions are kept up to date via updater.py, a utility that updates versions.yaml latest charts and (selected) images.

The pipeline attempts to uplift and deploy latest versions on daily bases.

Hardware

While HW configuration is flexible, Airship Seaworthy reference manifests reflect full HA deployment, similar to what might be expected in production.

Reducing number of control/compute nodes will require site overrides to align parts of the system such as Ceph replication, etcd, etc.

Airship Seaworthy site has 6 DELL R720xd bare-metal servers: 3 control, and 3 compute nodes. See host profiles for the servers here.

Control (masters)
  • cab23-r720-11
  • cab23-r720-12
  • cab23-r720-13
Compute (workers)
  • cab23-r720-14
  • cab23-r720-17
  • cab23-r720-19

Network

Physical (underlay) networks are described in Drydock site configuration here. It defines OOB (iLO/IPMI), untagged PXE, and multiple tagged general use networks.

Calico overlay for k8s POD networking uses IPIP mesh.

BGP peering is supported but not enabled in this setup, see Calico chart.
