The current GPU installer was built in 2017, from source that no longer
exists in Kubernetes ([adding commit][1]. The image was built on 2017-06-13.
Unfortunately, this installer no longer appears to work. When debugging
on the same node type as used by test-infra, it failed to build the
driver as the kernel sha was no longer available.
This lead to needing to find a new way to install GPUs. The smallest
logical change was switching to [cos-gpu-installer][2]
. There is a newer version of this available on [googlesource][3] that
I have not yet tested as it's not clear what the state of the project
is, as I couldn't find docs outside of the source itself.
We install things to the same location as previously to avoid needing
extra downstream changes. There are a couple of weird issues here
however, like needing to run the container twice to correctly update the
LD Cache.
