Minikube: localkube: panic: unable to read certificate-authority /var/lib/localkube/\var\lib\localkube\certs\ca.crt

[F21]

Is this a BUG REPORT or FEATURE REQUEST? (choose one): BUG REPORT

Please provide the following details:

Environment:

Minikube version: minikube version: v0.22.2

• OS: Windows 10 64-bit (Creators Update with latest updates)
• VM Driver: VirtualBox
• ISO version: v0.23.4
• Install tools: n/a
• Others: n/a

What happened:
Minikube provisioned the VM, but it does not work correctly.

What you expected to happen:
The Minikube cluster should work correctly.

How to reproduce it (as minimally and precisely as possible):

1. Downloaded minikube 0.22.2 and placed it in my PATH.
2. Deleted C:/users/user/.minikube and C:/users/user/.kube
3. Ran minikube start.
4. The VM provisions correctly.
5. Tried to get into the dashboard:

$ minikube dashboard
Could not find finalized endpoint being pointed to by kubernetes-dashboard: Error validating service: Error getting service kubernetes-dashboard: services "kubernetes-dashboard" not found

$ minikube dashboard
Could not find finalized endpoint being pointed to by kubernetes-dashboard: Error validating service: Error getting service kubernetes-dashboard: Get https://192.168.99.101:8443/api/v1/namespaces/kube-system/services/kubernetes-dashboard: dial tcp 192.168.99.101:8443: connectex: No connection could be made because the target machine actively refused it.

1. Docker in minikube showed no containers running at all:

$ minikube ssh "docker ps -a"
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

1. In addition, since my CWD is C:/users/user/Desktop, I see this folder created C:/users/user/Desktop/C_/users/user/.minikube.

Output of minikube logs (if applicable):

Anything else do we need to know:

The certificate actually does exist

$ pwd

$ ls
apiserver.crt  ca.crt  proxy-client-ca.crt  proxy-client.crt
apiserver.key  ca.key  proxy-client-ca.key  proxy-client.key
$

But obviousy it is in /var/lib/localkube/certs, not /var/lib/localkube/\var\lib\localkube\certs\

is the fix provided in #1982 ready to use ? can I download the latest .exe and install it fresh

[IljaKroonen]

After looking at some URLs I found out how to download the new executable (1982 is the # of the MR)

https://storage.googleapis.com/minikube-builds/1982/minikube-windows-amd64.exe

[EricssonVNFCloud]

Thanks buddy !!! do you know whether we need to remove the old one before installing this new one ??

[IljaKroonen]

I just replaced the executable in my installed folder, ran minikube delete and minikube start, and everything worked

[EricssonVNFCloud]

I am still getting this error:

minikube config set WantKubectlDownloadMsg false

Could not find finalized endpoint being pointed to by kubernetes-dashboard: Error validating service: Error getting service kubernetes-dashboard: Get https://19

[richardjharding]

I just tried the build on the link above 1982 and still can't get minikube running on hyperv - this the output I get

[tjsb]

I am having the same issue.

[maarten-daalder-isaac]

On Windows 10 the build provided by IljaKroonen works now, before I had the weird /var/...\var...\certs issue as well.

I started Minikube with the following command:
minikube start --vm-driver hyperv --hyperv-virtual-switch minikube-virt-switch --kubernetes-version v1.7.5 -v 999 --disk-size 4g
Then I could run minikube dashboard without problems.

[secat]

@r2d4 Is there going to be an official release version 0.22.3?

[EricssonVNFCloud]

On Windows 10 the build provided by IljaKroonen works now, before I had the weird /var/...\var...\certs issue as well.

I started Minikube with the following command:
minikube start --vm-driver hyperv --hyperv-virtual-switch minikube-virt-switch --kubernetes-version v1.7.5 -v 999 --disk-size 4g
Then I could run minikube dashboard without problems.

Can you provide more details ??
What is your hyperv version ??
Windows 10 , 32 bit or 64 bit ??

[EricssonVNFCloud]

Seems minikube is Jinxed on Windows.

[richardjharding]

I had the same experience -at first the build linked above failed with cert issues but after deleting and issuing another minikube start its all working

win10 build 15063.608
minikube is reporting 0.22.2 but its the build from link to 1982 above
hyperv 10.0.15063.502

hope that helps

[maarten-daalder-isaac]

Hi @EricssonVNFCloud,

64bit Windows 10, version 1703 OS build 15063.608
HyperV version 10.0.15063.502

Of course, I had to create a virtual switch first.

[rwenz3l]

Same for me with virtualbox. Seems to be resolved, when creating a new machine with the build 1982 that was linked.

[endophage]

Build 1982 is failing on startup for me.

OS: Windows 10 Pro
minikube: @IljaKroonen's build linked above
Hyper-V: 10.0.15063.0

```
$PS> minikube start -v 10 --vm-driver=hyperv --hyperv-virtual-switch=
...

Then it just retries every few seconds, printing that final line of the log over and over.

[JacekFeliksiakMYOB]

Hi there,

edit
I edited this message, because it is highly possible that it is cause by docker-machine:(
edit

I have the same problem after IljaKroonen build 1982. Before and after this changes I have the same status:

C:\Kubernetes\Workspace>minikube status
minikube: Running
cluster: Stopped
kubectl: Correctly Configured: pointing to minikube-vm at fe80::215:5dff:fe32:871a

my comand:

minikube start --kubernetes-version="v1.7.5" --vm-driver="hyperv" --memory=1024 --hyperv-virtual-switch="switch" --v=7 --alsologtostderr

my virtual switch - external / Ethernet

I am adding some logs

My cluster has a status of stopped as well. Windows 10 + Hyper-V (and yes there is a virtual-switch)

minikube start --kubernetes-version "v1.7.5" --vm-driver "hyperv" --memory=1024 --hyperv-virtual-switch "MiniKubeSwitch" -v 999 --disk-size 4g --alsologtostderr

Result:

>minikube.exe status
minikube: Running
cluster: Stopped
kubectl: Correctly Configured: pointing to minikube-vm at 10.0.0.44

What else can I provide to help fix this issue?

[r2d4]

This should be fixed by the latest release 0.22.3

Please help as I think I'm in the last step of setting up the minikube on my windows 10 machine

[richardjharding]

Hi
I sometimes see something similar - usually when the ip of the vm has changed eg when you change network connections on the host machine

Do you see anything when you do

minikube dashboard

it should pop up a browser with the dashboard - if not then what usually resolves it for me is

minikube stop
minikube start

That seems to sort out the certificates then minikube dashboard should work

[VenkateshSrini]

Hi,
My Bad. I updated the kubectl to 1.8.0. It is working now

[rlitman-10c]

Just tested on 0.22.3, it still happens (I did a clean install - removed the VM, .minikube, etc...). In previous versions (0.22.*) I once saw a kernel panic in minikube VM (but I don't know where to find logs for that event), machine restarted and docker daemon was running, but there were no k8s containers. As we use dhcp, the VM's IP address gets changed every time this happens, so my guess is VM gets restarted and that causes the k8s inside to "die".

Ditto! 0.22.3 cluster is still stopped. Is there a log I can send you?

[AneetaGeorge]

Hi, I'm facing similar issues. "minikube start" starts the cluster but when i try to run anything with kubectl it says "unable to connect to server : Service unavailable". Can someone please help me?

[maarten-daalder-isaac]

Using Hyper-V on Windows 10 Creator Update I had to do the following:

• Use a virtual switch that is bridged to a real network (External), because Hyper-V does not supply DHCP/DNS/Gateway server(s).
• Set a fixed MAC address, otherwise it would suddenly get a new IP address which messes things up
• Set a fixed memory amount, by default it gradually reduces the memory

[AneetaGeorge]

I'm using virtualbox in windows 10 64 bit . Is there any more details that I should provide?I'm really new to kubernetes

[shahrouzz]

I have similar issues with minikube 0.23 on windows 10 with the hyperv driver.
Everything starts up fine and then there is a kernel panic after using the cluster for a minute or two.

minikube 0.19.1 runs fine on with the same setup.

[neoGeneva]

I'm also seeing a kernel panic with minikube v0.23.0 on Windows 10 using the hyperv driver.

I get it pretty reliably while trying to install fabric8 using gofabric8 deploy --package system -n fabric8

I'm not familiar with debugging kernel panics, so I couldn't figure out how to use get any more of the log out other than what was displayed in the console:

Hey guys

I could reproduce this issue in the latest minikube on Windows 8.1

Environment:

Minikube version: minikube version: v0.23.0

OS: Windows 8.1 64-bit
VM Driver: VirtualBox
Install tools: n/a
Others: n/a

What happened:

1. After restarted windows without stopping minikube vm,
2. Next time, the minikube provisioned the VM, but it does not work correctly.

What you expected to happen:
The Minikube cluster should work correctly.

How to reproduce it (as minimally and precisely as possible):

Downloaded minikube 0.23.0 and placed it in my PATH.
Deleted C:/users/user/.minikube and C:/users/user/.kube
Ran minikube start.
The VM provisions correctly.
Tried to do something with the minikube (e.x deploying wordpress, mysql)
Then, shutdown/restart your PC without stopping the minikube vm
Finally, after we re-start the minikube, it could not work correct anymore.

$ minikube dashboard
Could not find finalized endpoint being pointed to by kubernetes-dashboard: Error validating service: Error getting service kubernetes-dashboard: Get https://192.168.99.100:8443/api/v1/namespaces/kube-system/services/kubernetes-dashboard: dial tcp 192.168.99.100:8443: connectex: No connection could be made because the target machine actively refused it.

$ minikube status
minikube: Running

after checking the logs

I noticed one issue:

[gbraad]

@neoGeneva was the kernel panic reproducible? it looks like an issue with the hypervisor communication driver. This is not really actively used in the Minikube iso, except for sending the IP address to the hypervisor over hvkvp AFAIR.

[neoGeneva]

@gbraad yeah, every time I try and install fabric8 (version 0.4.173) it has a kernel panic after a five or six minutes, even with a fresh install of minikube.

minikube logs returns -- No entries -- after the VM reboots, and I tried getting more logs out with netconsole, but I'm not familiar enough with debugging on Linux to get it going.

If there is anything else I can provide please let me know.

[neoGeneva]

@gbraad Just letting you know that I'm still seeing the issue even without fabric8, seems to be after about every 15-20 minutes I get a kernel panic.

[gbraad]

@neoGeneva this is a different issue, but can you share your system configuration, host OS, etc. Have you also tried using any other ISO (previous version or B2D)?

[neoGeneva]

@gbraad I think this is probably a different issue from this one, so I've opened a new issue: #2195

PS X:\Playground\kubernetesplay> minikube status

When the cluster is in this state above, just executing minikube start fixed the issue for me.

I'm having this issue as well - win 8.1 x64/Vbox

Tried running minikube start again as noted by @barbarosalp but no change.

[ALYSShow]

Same issue here. Running minikube start a couple of times doesn't seem to fix it. A restart didn't help as well.

It is worth noting that my setup was working normally for some time then suddenly stopped (might be after a restart without properly stopping minikube and docker-machine).

I got the same issue every time my Mac wakes up from sleep(it started okay before going to sleep though).

Closing open localkube issues, as localkube was long deprecated and removed from the last two minikube releases. I hope you were able to find another solution that worked out for you - if not, please open a new PR.
