Previously, minikube has been shipped with the default CNI config
(/etc/cni/net.d/k8s.conf) in its rootfs. This complicated a lot
when using a custom CNI plugin, as the default config was picked
by kubelet before the custom CNI plugin has installed its own CNI
config. So, the end result was that some Pods were attached to a
network defined in the default config, and some got managed by
the custom plugin.
This commit introduces the flag "--enable-default-cni" to
"minikube start" to trigger the provisioning of the default CNI
config.

* Change restart policy on gvisor pod
Change the restart policy on the gvisor pod to Always. This way, if a
user runs
minikube addons enable gvisor
minikube stop
minikube start
when the addon manager tries to restart the gvisor pod, it will be
restarted and gvisor will start running automatically. This PR also adds an
integration test for this functionality.
* Test stop and start
* Revert test to delete
Revert test to delete for now, for some reason "stop" and then "start"
is failing both locally and in Jenkins for VirtualBox with a "panic test
timed out after 30 min" error
This PR adds the code for enabling gvisor in minikube. It adds the pod
that will run when the addon is enabled, and the code for the image
which will run when this happens.
When gvisor is enabled, the pod will download runsc and the
gvisor-containerd-shim. It will replace the containerd config.toml and
restart containerd.
When gvisor is disabled, the pod will be deleted by the addon manager.
This will trigger a pre-stop hook which will revert the config.toml to
it's original state and restart containerd.
This change is a bit of a hack to make IP routing work over the virtio-net interface - it forces the virtio-net interface (bridge100) created by hyperkit/xhyve to reset via removing and readding the single member of the interface. Without this "reset" packets are just simply lost most of the time, despite a completely healthy IP route.
This error was also the reason for a large percentage of our integration test failures. While reducing the flakiness of tunnel related tests I also increased the timeout requirement and adding retries to the nginx request in TestTunnel.

Previously we were mixed between the two forms. This commit picks %v,
which is consistent with the Kubernetes code base. They both effectively
do the same thing in this case, though %v works with any object, and %s
only with string objects.
Make future failures to this test easier to debug. Here's an example of
the test failure I ran into:
--- FAIL: TestFunctional/EnvVars (0.58s)
cluster_env_test.go:36: SetEnvFromEnvCmdOutput: Error: No variables were parsed from docker-env output:
set -gx DOCKER_TLS_VERIFY "1";
set -gx DOCKER_HOST "tcp://192.168.39.199:2376";
set -gx DOCKER_CERT_PATH "/usr/local/google/home/tstromberg/.minikube/certs";
set -gx DOCKER_API_VERSION "1.35";
# Run this command to configure your shell:
# eval (minikube docker-env)
* Separate start args from args passed to every command. This is so
that we can call `minikube logs` and `minikube status` with the proper
flags (for the bootstrapper)
* Add a NewMinikubeRunner function to make getting a minikube runner
easier.
We were using an alpha v1.6 kubectl to run 1.5 and 1.6 branches of
minikube at the same time. Since we've merged in 1.6, we will always
use 1.6 kubectl. I've updated the slaves to have it.
In TestStartStop(), check for stopped status once in 5 seconds,
up to 30 seconds, instead of always sleeping for 30 seconds
before stopping it. That way we can reduce duration of the test.
To do that, we need to split out MinikubeRunner.CheckStatus() into
CheckStatusNoFail() that doesn't lead to T.Fatalf(). Other call sites
of CheckStatus() would not be then affected.
