`set -e` does not catch errors in bash command substituions like `echo $(bad cmd)` so bazel thinks it succeeded and cached the result. PiperOrigin-RevId: 321412327

VM Images & Tests
All commands in this directory require the gcloud project to be set.
For example: gcloud config set project gvisor-kokoro-testing.
Images can be generated by using the vm_image rule. This rule will generate a
binary target that builds an image in an idempotent way, and can be referenced
from other rules.
For example:
vm_image(
name = "ubuntu",
project = "ubuntu-1604-lts",
family = "ubuntu-os-cloud",
scripts = [
"script.sh",
"other.sh",
],
)
These images can be built manually by executing the target. The output on
stdout will be the image id (in the current project).
For example:
$ bazel build :ubuntu
Images are always named per the hash of all the hermetic input scripts. This allows images to be memoized quickly and easily.
The vm_test rule can be used to execute a command remotely. This is still
under development however, and will likely change over time.
For example:
vm_test(
name = "mycommand",
image = ":ubuntu",
targets = [":test"],
)
