I installed k8s dashboard as written in "https://github.com/kubernetes/dashboard".
However, I cannot access this URL. http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/
I receive
「Error trying to reach service: 'proxyconnect tcp: dial tcp: lookup $http_proxy: no such host」.(I can access this URL. http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/)
Here is my status. My cluster seem to be no problem. (And I'm under proxy circumstances, but there is no problem docker pull.)

I'm sorry I'm not good at English. Please answer this question.

Error trying to reach service: 'proxyconnect tcp: dial tcp: lookup $http_proxy: no such host'First thing which I noticed is that you use the same url for http and https:
# docker info | grep Proxy
HTTP Proxy: http://10.227.74.6:3128
HTTPS Proxy: http://10.227.74.6:3128For HTTPS Proxy url should start with https.
Modify /etc/sysconfig/docker file, example:
# cat /etc/sysconfig/docker
HTTP_PROXY="http://10.227.74.6:3128"
HTTPS_PROXY="http://10.227.74.6:3128"
NO_PROXY="localhost,127.0.0.1,10.227.74.4,10.227.74.37,10.96.0.0/12,10.244.0.0/16"Then configure /etc/bashrc file:
# cat /etc/bashrc
export http_proxy="http://10.227.74.6:3128"
export https_proxy="https://10.227.74.6:3128"
export no_proxy="localhost,127.0.0.1,10.227.74.4,10.227.74.37,10.96.0.0/12,10.244.0.0/16"After applying changes restart the Docker daemon.
Please follow those steps during proxy setup: proxy-configuration.
More information about setting proxy you can find here: proxy-server.
It might be an intermittent issues due to your corporate proxy settings. The URL is working for me.
