Greetings! We are looking at overhauling our build system to move to
diskless booting. From our investigation we've landed on two potential
options that have been mentioned by multiple people.
Warewulf: Industry proven and supports building images from Containers.
OpenCHAMI: New comer, modern microservices approach that also supports
building images from Containers.
I've done some reading up on both but I would love to hear your
thoughts/experiences with either or both.
Here are our criteria:
1.
Can handle diskless booting for a 2k node cluster
2.
Good history of updates and responsiveness to issues
3.
Active and good sized community is a plus
4.
Good docs
5.
Conforms to "standards"
6.
Building images easily via CI pipeline would be great
Main use case is for us to replace our various (usually multi-day)
upgrades with this new system. We expect that we will still need to do
some level of node config outside of the new system (Puppet).
Thanks in advance.
