2020-07-13iptables: remove useless ip6tables VM rulesKevin Krakauer
This rule isn't restored when the Kokoro VM is restarted, so it's not doing anything. And the problem it was meant to solved is instead addressed by https://github.com/google/gvisor/pull/3207. PiperOrigin-RevId: 321026846
2020-06-26Enable docker IPv6 in kokoroKevin Krakauer
We need docker IPv6 for ip6tables tests. Docker has spotty IPv6 support, so just enabling IPv6 in daemon.json breaks the Ruby image test (AFAICT it breaks anything that tries to use IPv6 to reach the internet). An ip6tables NAT rule is added to handle this. We could make these changes as part of scripts/, but these would overwrite global values and possibly break users' systems. PiperOrigin-RevId: 318508209

2020-05-20Upgrade to Bazel 3.1.0.Nicolas Lacasse
This upgrades the Kokoro images, bazel toolchains used by RBE runners, and rules_go, gazelle, and go toolchain versions. PiperOrigin-RevId: 312522097

2020-04-24Standardize all Docker images.Adin Scannell
This change moves all Docker images to a standard location, and abstracts the build process so that they can be maintained in an automated fashion. This also allows the images to be architecture-independent. All images will now be referred to by the test framework via the canonical `gvisor.dev/images/<name>`, where `<name>` is a function of the path within the source tree. In a subsequent change, continuous integration will be added so that the images will always be correct and available locally. In the end, using `bazel` for Docker containers is simply not possible. Given that we already have the need to use `make` with the base container (for Docker), we extend this approach to get more flexibility. This change also adds a self-documenting and powerful Makefile that is intended to replace the collection of scripts in scripts. Canonical (self-documenting) targets can be added here for targets that understand which images need to be loaded and/or built. PiperOrigin-RevId: 308322438
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
