Is Istio Auth enabled or not ? 未启用身份验证，我使用istio-demo.yaml来安装istio

What happened ：我尝试使用外部示例（ServiceEntry）：

cat <<EOF | istioctl create -f -
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: httpbin-ext
spec:
  hosts:
  - httpbin.org
  ports:
  - number: 80
    name: http
    protocol: HTTP
EOF

cat <<EOF | istioctl create -f -
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: google-ext
spec:
  hosts:
  - www.google.com
  ports:
  - number: 443
    name: https
    protocol: HTTPS
EOF

I keep getting errors when I try to curl from the sleep pod:

root@sleep-6ccf857cc6-b9jh4:/#  curl http://httpbin.org/headers -I
HTTP/1.1 503 Service Unavailable
content-length: 19
content-type: text/plain
date: Thu, 14 Jun 2018 10:40:20 GMT
server: envoy

root@sleep-6ccf857cc6-b9jh4:/# curl -I https://www.google.com
curl: (35) Unknown SSL protocol error in connection to www.google.com:443

Some log output from the istio proxy sidecar of the sleep pod:

    我在AWS上运行此功能，但能够在istio / github / issues页面的帮助下修复此问题...

    不得不将RESOLUTION：DNS添加到serviceentry

    cat <<EOF | istioctl create -f -
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: httpbin-ext
spec:
  hosts:
  - httpbin.org
  ports:
  - number: 80
    name: http
    protocol: HTTP
  resolution: DNS
EOF

cat <<EOF | istioctl create -f -
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: google-ext
spec:
  hosts:
  - www.google.com
  ports:
  - number: 443
    name: https
    protocol: HTTPS
  resolution: DNS
EOF
