Project Update, Open Infrastructure Summit, Denver 2019 James Slagle, Emilien Macchi

April 2019

Hi!

What is TripleO?

• OpenStack on OpenStack (OoO)
• A project to install, upgrade and operate

OpenStack clouds using OpenStack APIs, including: ■ Heat ■ Ironic ■ Keystone ■ Mistral ■ Neutron ■ Nova ■ Swift ■ Zaqar

What a deployment looks like

What happened in Stein?

➡ First release where it’s 100% tested ➡ Tested on Fedora 28 (CentOS 8 will come later)

Python 3 ready

➡ Overcloud / Standalone

• Replacing ML2 OVS driver for Neutron
• Default driver in TripleO

➡ Undercloud: still work in progress

OVN (Open Virtual Network)

➡ Controlplane split

• controlplane nodes are deployed first
• then batches of compute/storage nodes can be added independently

without any update of the controlplane stack.

• separation of management operations between sites

➡ Distributed Compute/Storage Nodes

• deploy remote compute and storage nodes
• configure/create AZ per edge site
• services per site: nova, cinder, ceph, etcd
• separate clusters per site (ceph, etcd)

Edge Computing

Edge Computing

➔ Multiple stacks with split-controlplane

Edge Computing

➔ Multiple stacks with split-controlplane

➡ Provision baremetal over WAN using Spine/Leaf

• dhcrelay used to fwd dhcp

requests across L3

• Ironic direct deploy interface

instead of iscsi

Edge Computing - Spine/Leaf provisioning

➡ Support on the edge ➡ Bluestore support

• provide an alternative storage backend to filestore
• filestore remains the default

➡ Nautilus release by default

Ceph

➡ Podman is the new CLI to manipulate containers

• Integration with CRI-O
• Native pods support, optimized for Kubernetes
• No daemon, using systemd

➡ Buildah is the new CLI to manipulate images

• High compatibility with formats
• Complementary with Podman

➡ Apache now serves the local registry

• replace Docker Distribution on the Undercloud
• API compatibility is maintained

Containers

Docker is deprecated

➡ Deploy the overcloud with multiple layer 2 domains (e.g. 1/rack) ➡ Enables horizontal scalability ➡ Connectivity between L2 domains is done by routers

Routed networks

➡ Chrony replaces NTP ➡ Ironic Inspector supported on the Overcloud ➡ Nova multiple cells support (cells v2) ➡ TripleO UI is deprecated

Other news

Future roadmap

➡ Validation Framework ➡ In-flight validations ➡ Reducing Undercloud footprint in TripleO (Heat, Mistral, Zaqar, Swift) ➡ Improving HA when having network outages ➡ Ceph UI support ➡ Improving large scale deployments ➡ CI improvements

Cross-Project Work

➡ OpenStack Ansible: tempest role ➡ CI: zuul reproducer ➡
