WHAT’S NEXT @masonkatz
STACKI HAS 2 GOALS
1: Keep You Under the Threshold
Number of Servers

General Data Center
Clusters
PAIN
2: Stay Out of Your Way
DevOps / Configuration Tool
DHCP /DNS / TFTPNetworkDiskOS
In-housedevelopeddeployment
tools
- Disk Array Controller Configuration- Disk Partitioning Configuration
3: World Domination
UNRELEASED STUFF On Github right now
3.1
Bug Fixes
• network bridging • works for install network • still builds over one nic
• network bonding • command line • spreadsheets
Enhancements
• Host spreadsheets • 10x faster loading at scale
BIOS
iPXE • PXE on Steroids
• Supports • HTTP • WAN • iSCSI • Infiniband
Space Time
PXE
① c->* dhcp request ② s->c dhcp response ③ c->s tftp vmlinuz ④ c->s http ks.cfg ⑤ c->* http packages
iPXE
① c->* dhcp request ② s->c dhcp response ③ c->s tftp ipxe ④ c->* dhcp request ⑤ s->c dhcp response ⑥ c->* http vmlinuz ⑦ c->s http ks.cfg ⑧ c->* http packages
No More “Legacy Mode”
NETWORKING
IPv6 • Secondary Interfaces
• command line • Spreadsheets
• Primary is IPv4 • BIOS PXE • DHCP
• BTW – Turns 20 in 2018 (can drink in 2019)
API
STACK is the API • Today
• Shell (stack) • Python (stack.api.Call)
• Web Service • Django-based • Admin / User access control • Access all stack commands
• Remote Management • Shell (stack-ws) • Write your own client for *
CARTS & PALLETS
Simplify • Cart -> Pallet
• Usage • stack create pallet CART_DIRECTORY
• Convert site local carts into pallet .iso files • Developers might prefer this as well
• Wire Abstractions • Something simpler than XML • Not settled on anything yet …
backend.ini
[packages] foo

AddPackage(‘foo’) AddPackage(‘bar’)
if attr[‘rack’] = ‘10’: RunScript(‘script1.sh’)

REMOTE MANAGEMENT
Down The Stack • Support for DRAC, iLo, ?, IPMI
• Apply or Detect Configuration
• Power On/Off
• Setting (fixing) Boot Order
• Firmware Upgrades
• Serial Console
• Temperature Monitoring
100% Hands Free https://github.com/jmcdice/stack-tools
• Answer script for FE build
• Automatically turn on and build BE nodes
• Requires a custom stacki.iso • ks.cfg file • site.attrs file • extend-*.xml file(s)
• Working closely with Nokia (see git repo above)

OS
Multiple Versions • Today
• RHEL/CentOS 6.x FEs build 6.x BEs • RHEL/CentOS 7.x FEs build 7.x BEs
• Cross Building • RHEL/CentOS 7.x FEs build 7.x and 6.x BEs
Multi OS • Today
• Ubuntu • CoreOS
• These are lightweight • No Pallets / Carts • No Dynamic Profiles
• Go deeper with Ubuntu
• Explore SUSE, Fedora, Debian
