Rebooting also useless.
Turns out it was because of turned on VPN on network settings. Answer found here

There are many question around this topic, but not the specific info I am after.
Host OS is Mac, and recently had to uninstall Docker Desktop due to their licensing change. So instead we have moved to minikube, and it is all working great with VirtualBox driver.
But ideally we would like to use the hyperkit driver, as it requires less resources than virtualbox, and is (anecdotally) faster. This also all works great until we connect to our VPN (using cisco anyconnect) and then all outbound networking from within the minikube VM stops working. e.g.
k8> minikube ssh "traceroute 8.8.8.8"
traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 46 byte packets
1 host.minikube.internal (192.168.64.1) 0.154 ms 0.181 ms 0.151 ms
2 * * *
Everything else is is fine, inbound networking via ingress is all good. And maven-docker-plugin is happily creating images with the minikube docker daemon. Just nothing outbound.
So figured I'd try to work with VPNKit as I have read it is meant to address this issue. But cannot find a lot of detailed documentation, and so am struggling.
We have tried starting VPNKit with minimal config:
vpnkit --ethernet /tmp/vpkit-ethernet.socket --debug
And then attempt to start minikube, but it fails:

💡 Suggestion: Hyperkit is broken. Upgrade to the latest hyperkit version and/or Docker for Desktop. Alternatively, you may choose an alternate --driver

And in the vpnkit log we see:
time="2022-02-14T06:07:57Z" level=debug msg="usernet: accepted vmnet connection"
time="2022-02-14T06:07:57Z" level=warning msg="Uwt: Pipe.listen: rejected ethernet connection: EOF"
time="2022-02-14T06:08:07Z" level=debug msg="usernet: accepted vmnet connection"
time="2022-02-14T06:08:07Z" level=warning msg="Uwt: Pipe.listen: rejected ethernet connection: EOF"
So kind of implies something is not right with how I started vpnkit. Have played with IP args to ensure it all matches, but does not help.
My guess is that the --ethernet=path arg is not the right type of socket. I have seen there is also --vsock-path=path but specifying this does not appear to create the socket file like --ethernet=path does. Do I have to create this some other way?
Or are there other config options I need to mess with. e.g. I thought --gateway-forwards=path could help, but can find no documentation on file format or contents.
So, I guess two main questions:
Is what we are trying even possible? Is it the the right way to go about it? Or is it much more complicated than simply running the vpnkit command?
If we are on the right track, does anyone have experience with this, and know how to set up the socket for minikube+vpnkit+hyperkit? What args, config, or other setup is required?
And just to note: --hyperkit-vpnkit-sock=auto is not an option for us, as we do not have docker installed, and so the docker socket file does not exist.
And just in case its a version issue:

I'm going crazy; I have spent way too much time and would immensely appreciate any help.
Here's the problem:
When I launch Docker Desktop, the engine stays on Stopped, and never launches.
I'm on Windows 11
I've installed the WSL 2 backend (following these steps), noticed Hyper-V was not installed so I installed it
I've tried to uninstall and reinstall docker desktop
I've tried to launch docker desktop as admin
I've tried using: 'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon
I'm really stuck.
When I run self diagnose:
"C:\Program Files\Docker\Docker\resources\com.docker.diagnose.exe" check
I get this (trimmed a bit to comply to character limit):

Please investigate the following 3 issues:
1 : The test: are the LinuxKit services running?
Failed with: failed to ping VM diagnosticsd with error: Get "http://ipc/ping": open \\.\pipe\dockerDiagnosticd: The system cannot find the file specified.
The Docker engine runs inside a Linux VM as a service. Therefore the services must have started.
2 : The test: are the backend processes running?
Failed with: 3 errors occurred:
* vpnkit-bridge.exe is not running
* vpnkit.exe is not running
* com.docker.proxy.exe is not running
Not all of the backend processes are running.
3 : The test: is the VM networking working?
Failed with: network checks failed: Post "http://ipc/check-network-connectivity": open \\.\pipe\dockerDiagnosticd: The system cannot find the file specified.
VM seems to have a network connectivity issue. Please check your host firewall and anti-virus settings in case they are blocking the VM.
I've authorized Docker Desktop through the firewall, but it didn't change anything. I'd be so grateful for any help!
I payed Docker Pro subscription to contact the support and got this answer that SOLVED it ! Pfiew I had really tried everything, couldn't have guessed that.
The answer :
Hi,
We have identified an issue in Docker Desktop 4.5.0 where the default backend selected after installing is not the correct one.
We will release a Docker Desktop 4.5.1 shortly to address this, in the meanwhile you can switch to the correct backend by editing the following file:
%APPDATA%\Docker\settings.json and at the bottom change the value for the wslEngineEnabled field to true.
After that Docker Desktop should start correctly.
Sorry for the inconvenience
And it worked !!
In a docker container I want to run k8s.
When I run kubeadm join ... or kubeadm init commands I see sometimes errors like
\"modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could
not open moddep file
'/lib/modules/3.10.0-1062.1.2.el7.x86_64/modules.dep.bin'.
nmodprobe:
FATAL: Module configs not found in directory
/lib/modules/3.10.0-1062.1.2.el7.x86_64",
err: exit status 1
because (I think) my container does not have the expected kernel header files.
I realise that the container reports its kernel based on the host that is running the container; and looking at k8s code I see
// getKernelConfigReader search kernel config file in a predefined list. Once the kernel config
// file is found it will read the configurations into a byte buffer and return. If the kernel
// config file is not found, it will try to load kernel config module and retry again.
func (k *KernelValidator) getKernelConfigReader() (io.Reader, error) {
possibePaths := []string{
"/proc/config.gz",
"/boot/config-" + k.kernelRelease,
"/usr/src/linux-" + k.kernelRelease + "/.config",
"/usr/src/linux/.config",
}
so I am bit confused what is simplest way to run k8s inside a container such that it consistently past this getting the kernel info.
I note that running docker run -it solita/centos-systemd:7 /bin/bash on a macOS host I see :
# uname -r
4.9.184-linuxkit
# ls -l /proc/config.gz
-r--r--r-- 1 root root 23834 Nov 20 16:40 /proc/config.gz
but running exact same on a Ubuntu VM I see :
# uname -r
4.4.0-142-generic
# ls -l /proc/config.gz
ls: cannot access /proc/config.gz
[Weirdly I don't see this FATAL: Module configs not found in directory error every time, but I guess that is a separate question!]
UPDATE 22/November/2019. I see now that k8s DOES run okay in a container. Real problem was weird/misleading logs. I have added an answer to clarify.
I do not believe that is possible given the nature of containers.
You should instead test your app in a docker container then deploy that image to k8s either in the cloud or locally using minikube.
Another solution is to run it under kind which uses docker driver instead of VirtualBox
https://kind.sigs.k8s.io/docs/user/quick-start/
It seems the FATAL error part was a bit misleading.
It was badly formatted by my test environment (all on one line.
When k8s was failing I saw the FATAL and assumed (incorrectly) that was root cause.
When I format the logs nicely I see ...

There are other errors later, which I originally though were a side-effect of the nasty looking FATAL error e.g. .... "[util/etcd] Attempt timed out"]} but I now think root cause is Etcd part times out sometimes.
Adding this answer in case someone else puzzled like I was.
I'm using Windows 10 Home and I got this error when connecting to docker:
ERRO[0044] failed to dial gRPC: cannot connect to the Docker daemon. Is 'docker daemon' running on this host?: dial tcp 192.168.99.101:2376: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Can anybody help? I have seen solutions for Linux and OS, but not for windows
I also use Window 10 Home edition,
On windows, run cmd in adminstrator mode
and run the folowing lines of code
docker-machine start
docker-machine.exe env --shell cmd > e:\servers\docker\setenv.bat
call e:\servers\docker\setenv.bat
del e:\servers\docker\setenv.bat
Continue in the same CMD instance to run your docker client commands
Dont forget to change docker folder path based on your environments.
Adding my answer from ERRO[0043] failed to dial gRPC: unable to upgrade to h2c, received 501:
Following one of the comments in https://github.com/docker-library/docker/issues/71, I enabled Experimental features in Settings->Daemon and the problem went away. I have no idea how or why it fixed it and another commenter there says they fixed it by disabling Experimental features.
I have installed docker on Windows 10, run it as administrator.
It's still in the process of launching (starting) after half an hour.

I am trying to reboot, shut down PC, virtualization is enable in bios.
Could you give me some advise to solve the problem?
I had a similar problem some weeks ago with a new user of our systems.
In my case i forgot to add the user to the docker-users group.
Further problems/solutions that i already had:
not enough memory, docker consumes some of it
Crashed containers
Firewall or other tools that block even local TCP access
Bad docker config in %ProgramData%\Docker\config\daemon.json, you could for example try to set it to an empty json file ({})
