1. Stacki aims to simplify server provisioning and management by keeping servers under a certain threshold and staying out of the way with tools for deployment, networking, and storage configuration. 2. Upcoming releases will focus on improvements to networking including IPv6 support, a new API, simplifying carts into pallet images, and expanding remote management capabilities to additional hardware. 3. Stacki supports multiple Linux distributions and aims to expand support for operating systems like Ubuntu while encouraging community development and contributions.

2. STACKI HAS 2 GOALS

3. 1: Keep You Under the Threshold
Number of Servers
ManagementComplexity
General Data Center
Clusters
PAIN

4. 2: Stay Out of Your Way
DevOps / Configuration Tool

tools
- Disk Array Controller Configuration
- Disk Partitioning Configuration

5. 3: World Domination

6. UNRELEASED STUFF
On Github right now

7. 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

8. BIOS

9. iPXE
• PXE on Steroids
• Supports
• HTTP
• WAN
• iSCSI
• Infiniband

10. 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

11. No More “Legacy Mode”

12. NETWORKING

13. IPv6
• Secondary Interfaces
• command line
• Spreadsheets
• Primary is IPv4
• BIOS PXE
• DHCP
• BTW – Turns 20 in 2018 (can drink in 2019)

14. API

15. 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 *

16. CARTS & PALLETS

17. 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 …

18. backend.ini
[packages]
foo
bar
[post]
script1.sh
script2.py
/export/stack/carts/local
bin/script1.sh
bin/script2.py
config/backend.ini
graph/
nodes/
RPMS/

19. config.py
if appliance == ‘backend’:
AddPackage(‘foo’)
AddPackage(‘bar’)
if attr[‘rack’] = ‘10’:
RunScript(‘script1.sh’)
function1()

20. REMOTE
MANAGEMENT

21. 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

22. 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)

23. ks.cfg
install
url --url file:///mnt/cdrom
lang en_US
keyboard us
network --onboot yes --device enp2s0f2
--bootproto static --ip 172.29.55.10
--netmask=255.255.255.0
--gateway 172.29.55.1
--noipv6 --hostname eldora.cloud-band.com
