Docker desktop - kubernetes failed to start

8/8/2020

I have installed Docker Desktop (version : 2.3.0.4) and enabled Kubernetes. I deployed couple of PODS and everything was working fine, Since yesterday I am facing a weird issue mentioned below:

Unable to connect to the server: dial tcp 127.0.0.1:6443: connectex: No 
connection could be made because the target machine actively refused it.

As such, no changes were made on my system. I am using Linux Containers on Windows 10 machine.

Following steps I have tried:

  1. Restarted the Docker Desktop
  2. Tried the same with minikube and Docker Desktop both
  3. Tried to disable the firewall but due to some permissions, I am not able to turn it off.
  4. I have reset the kubernetes cluster as well.

As @N-ate mentioned above, after clicking Clean/Purge Data which removes all downloaded images from my computer, now docker and kubernates are running properly.
As you can see in the image below, I only have kubernates images running on docker and it takes most of the allocated memory. I guess the failure of starting kubernates was related to this memory issue. docker and kuber running image

Finally,I found the solution for this.

VPN was causing the issue, I am using my office laptop and after restart, VPN was enabled and logged-in and due to this Kubernetes was not working.

After disabling the VPN, Kubernetes cluster working fine.

Hope that helps others as well.

For me, just "Clean and Purge" wasn't enough. Here is what I did.

  1. Log off VPN
  2. Go to bug and "Clean and Purge Data"
  3. Also choose "Reset to Factory Defaults"
  4. Restart Docker Desktop
  5. Choose "Enable Kubernetes"

At this point, the "Starting" took a while for Kubernetes to be enabled. Now's it all good.
