2020-04-20Add a functional vm_test for root_test.Adin Scannell
This change renames the tools/images directory to tools/vm for clarity, and adds a functional vm_test. Sharding is also added to the same test, and some documentation added around key flags & variables to describe how they work. Subsequent changes will add vm_tests for other cases, such as the runtime tests. PiperOrigin-RevId: 307492245
2020-02-06Add logic to run from baked images.Zach Koopmans
Change adds the following: - logic to run from "baked images". See [GVISOR_DIR]/tools/images - installers which install modified files from a workspace. This allows users to run benchmarks while modifying runsc. - removes the --preemptible tag from built GCE instances. Preemptible instances are much more likely to be preempted on startup, which manifests for the user as a failed benchmark. I don't currently have a way to detect if a VM has been preempted that will work for this change. https://cloud.google.com/compute/docs/instances/preemptible#preemption_process https://cloud.google.com/compute/docs/instances/preemptible#preemption_selection PiperOrigin-RevId: 293697949
2020-01-22Add tools for generating images.Adin Scannell
This formalizes the adhoc scripts previously in kokoro. The image targets can be used by e.g. benchmarks in order to automated image prepation. PiperOrigin-RevId: 290982744
