Small improvements to debugging and reducing integration test flakiness:
* added logging to kubeadm init in the SSHExecutor
* increasing timeout for RBAC creation via the kubernetes client set
* only log tunnel output to test logger
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.
After stopping any runtimes that aren't being used, if we're using
containerd then we need to restart it. This is because it competes with
cri-o to listen on port 10010, causing a necesary plugin to not be
installed. After stopping cri-o, we need to restart containerd so that
the plugin is installed.
I also added some preflight checks when using alternative runtimes.
kubeadm checks to make sure the Docker service is running, so I disabled
that. It also checks if a few ports are available; these are ports that
containerd uses, so I also added them to the ignore list.
This should finish the work started in #3211, which stopped alternative
runtimes but didn't restart containerd. I was able to run "minikube
start" with containerd locally with this change.
* Add config parameter for the cri socket path
Closes#3153
* Remove stray newline, when not using criSocket
* Add the --cri-socket parameter to configuration
Also fix the syntax for CRI-O, adding unix://
This commit introduces a new command, `minikube tunnel`, a LoadBalancer emulator functionality, that must be run with root permissions.
This command:
* Establishes networking routes from the host into the VM for all IP ranges used by Kubernetes.
* Enables a cluster controller that allocates IPs to services external `LoadBalancer` IPs.
* Cleans up routes and IPs when stopped (Ctrl+C), when `minikube` stops, and when `minikube tunnel` is ran with the `--cleanup` flag
- Updates Ingress-Controller Version to 0.19.0
- Adds Service Account for Ingress-Controller
- Adds Support for Prometheus
- Fixes bug with TCP/UDP ConfigMaps not Loading
- Adds more resource limits to default-backend
- Use new ingress class name
- Use app.kubernetes.io/xxxxxxxxxxx labels
This provides an additional level of security, by enforcing host checking, applying port randomization, and requiring explicit user intent to expose the service to the host.
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.
