Zach KoopmansandgVisor bot 6ec8414e15 Add GKE Sandbox MicroVM runtime support to gke_tester and testcluster.
- Add RuntimeTypeMicroVM with kata-clh handler, microvm RuntimeClass
  overhead, node selector, and toleration configurations.
- Automatically configure nested virtualization when creating MicroVM
  nodepools.
- Add GKE API environment (--env) and endpoint override (--endpoint)
  support for testing against common GKE environments (prod, staging,
  staging2, test). User flags take precedence over environment variables.
- Store endpoint in TestRange and Cluster protos to allow locating
  and deleting clusters across environments.
- Calculate memory requests with headroom to satisfy node allocatable
  limits on GKE nodepools.

Tests

The tests defined under this path are verifying functionality beyond what unit tests can cover, e.g. integration and end to end tests. Due to their nature, they may need extra setup in the test machine and extra configuration to run.

  • syscalls: system call tests use a local runner, and do not require additional configuration in the machine.
  • integration: defines integration tests that uses docker run to test functionality.
  • image: basic end to end test for popular images. These require the same setup as integration tests.
  • root: tests that require to be run as root. These require the same setup as integration tests.
  • util: utilities library to support the tests.

For the above noted cases, the relevant runtime must be installed via runsc install before running. Just note that they require specific configuration to work. This is handled automatically by the test scripts in the scripts directory and they can be used to run tests locally on your machine. They are also used to run these tests in kokoro.

Example:

To run image and integration tests, run:

make docker-tests

To run root tests, run:

make sudo TARGETS=test/root:root_test

There are a few other interesting variations for image and integration tests:

  • overlay: sets writable overlay inside the sentry
  • hostnet: configures host network passthrough, instead of netstack
  • kvm: runsc the test using the KVM platform, instead of systrap

The test will build runsc, configure it with your local docker, restart dockerd, and run tests. The location for runsc logs is printed to the output.
