How do I use proxy in microk8s.docker

I’m in china, so I can’t access k8s.gcr.io directly, and I use ‘lantern’ as a http/socks proxy to access it. So when I try to exec command microk8s.enable istio, the status of istio pod is always ContainerCreating the output of command kubectl describe is

Warning  FailedScheduling        64s (x3 over 65s)  default-scheduler                0/1 nodes are available: 1 node(s) had taints that the pod didn't tolerate.
  Normal   Scheduled               59s                default-scheduler                Successfully assigned istio-system/grafana-6b99c54645-pghj4 to tianyu-virtual-machine

I followed the article: https://docs.docker.com/config/daemon/systemd/#httphttps-proxy And now I can pull images via default docker(not microk8s.docker):

tianyu@tianyu-virtual-machine:~$ docker pull k8s.gcr.io/kube-apiserver:v1.13.3
v1.13.3: Pulling from kube-apiserver

Status: Image is up to date for k8s.gcr.io/kube-apiserver:v1.13.3

But when I try to pull image via microk8s.docker, the output is:

tianyu@tianyu-virtual-machine:~$ microk8s.docker pull k8s.gcr.io/kube-apiserver:v1.13.3 
[sudo] password for tianyu: 
Error response from daemon: Get https://k8s.gcr.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

How do I use proxy in microk8s.docker? or Can microk8s use default docker(not microk8s.docker)? or can I share the images between docker and microk8s.docker?

Ah I see, microk8s uses containerd on my system. The right file to edit is /var/snap/microk8s/current/args/containerd-env.

Hi @15050050972

Did you follow the proxy setup instructions in https://github.com/ubuntu/microk8s#deploy-behind-a-proxy ?

You will need to edit /var/snap/microks8/current/args/dockerd-env and restart MicroK8s (or just the dockerd shipped with MicroK8s).
