+[Ingress流量控制任务](/zh/docs/tasks/traffic-management/ingress/ingress-control)描述了如何配置入口网关以向外部公开HTTP服务。此任务描述如何使用TLS或双向TLS公开安全的HTTPS服务。
+
+## 准备工作{#before-you-begin}
+
+1. 执行[准备工作](/zh/docs/tasks/traffic-management/ingress/ingress-control#before-you-begin)中的步骤。完成[Ingress流量控制](/zh/docs/tasks/traffic-management/ingress/ingress-control)中[确定Ingress的IP和Port](/zh/docs/tasks/traffic-management/ingress/ingress-control/#determining-the-ingress-ip-and-ports)部分任务。执行完这些步骤后，您应该已部署Istio和 [httpbin]({{< github_tree >}}/samples/httpbin)服务，并设置了环境变量 `INGRESS_HOST` 和 `SECURE_INGRESS_PORT` 。
+
+1.  对于macOS用户，请验证您是否使用通过LibreSSL库编译的curl：
+
+    {{< text bash >}}
+    $ curl --version | grep LibreSSL
+    curl 7.54.0 (x86_64-apple-darwin17.0) libcurl/7.54.0 LibreSSL/2.0.20 zlib/1.2.11 nghttp2/1.24.0
+    {{< /text >}}
+
+    如果上述命令输出的是如图所示的LibreSSL版本，则curl命令应按照此任务中的说明正确运行。否则，请尝试使用curl的其他实现，例如在Linux机器上。
+
+## 生成客户端和服务器证书和密钥{#generate-client-and-server-certificates-and-keys}
+
+对于此任务，您可以使用自己喜欢的工具来生成证书和密钥。下面的命令使用[openssl](https://man.openbsd.org/openssl.1)
+
+1.  创建用于服务签名的根证书和私钥：
+
+    {{< text bash >}}
+    $ openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -subj '/O=example Inc./CN=example.com' -keyout example.com.key -out example.com.crt
+    {{< /text >}}
+
+1.  为 `httpbin.example.com` 创建证书和私钥：:
+
+    {{< text bash >}}
+    $ openssl req -out httpbin.example.com.csr -newkey rsa:2048 -nodes -keyout httpbin.example.com.key -subj "/CN=httpbin.example.com/O=httpbin organization"
+    $ openssl x509 -req -days 365 -CA example.com.crt -CAkey example.com.key -set_serial 0 -in httpbin.example.com.csr -out httpbin.example.com.crt
+    {{< /text >}}
+
+### 配置单机TLS入口网关
+
+1.  确定已在[准备工作](/zh/docs/tasks/traffic-management/ingress/ingress-control#before-you-begin)环节完成[httpbin]({{< github_tree >}}/samples/httpbin)服务的部署。
+
+1.  为Ingress网关创建Secret:
+
+    {{< text bash >}}
+    $ kubectl create -n istio-system secret tls httpbin-credential --key=httpbin.example.com.key --cert=httpbin.example.com.crt
+    {{< /text >}}
+
+    {{< warning >}}
+    Secret 名字 **不能** 以 `istio` 或 `prometheus` 开头, 且不能包含 `token` 字段。
+    {{< /warning >}}
+
+1.  为端口443定义一个带有 `servers:` 部分的网关，并将 `credentialName` 的值指定为 `httpbin-credential`。这些值与secret名称相同。 TLS模式的值应为 `SIMPLE`。
+
+    {{< text bash >}}
+    $ cat <<EOF | kubectl apply -f -
+    apiVersion: networking.istio.io/v1alpha3
+    kind: Gateway
+    metadata:

+    spec:
+      selector:
+        istio: ingressgateway # use istio default ingress gateway
+      servers:
+      - port:
+          number: 443
+          name: https
+          protocol: HTTPS
+        tls:
+          mode: SIMPLE
+          credentialName: httpbin-credential # must be the same as secret
+        hosts:
+        - httpbin.example.com
+    EOF
+    {{< /text >}}
+
+1.  配置网关的入口流量路由，定义相应的虚拟服务。
+
+    {{< text bash >}}
+    $ cat <<EOF | kubectl apply -f -
+    apiVersion: networking.istio.io/v1alpha3
+    kind: VirtualService
+    metadata:
+      name: httpbin
+    spec:
+      hosts:
+      - "httpbin.example.com"
+      gateways:
+      - mygateway
+      http:
+      - match:
+        - uri:
+            prefix: /status
+        - uri:
+            prefix: /delay
+        route:
+        - destination:
+            port:
+              number: 8000
+            host: httpbin
+    EOF
+    {{< /text >}}
+
+1.  发送HTTPS请求访问 `httpbin` 服务：
+
+    {{< text bash >}}
+    $ curl -v -HHost:httpbin.example.com --resolve "httpbin.example.com:$SECURE_INGRESS_PORT:$INGRESS_HOST" \
+    --cacert example.com.crt "https://httpbin.example.com:$SECURE_INGRESS_PORT/status/418"
+    {{< /text >}}
+
+    The `httpbin` service will return the
+    [418 I'm a Teapot](https://tools.ietf.org/html/rfc7168#section-2.3.3) code.
+
+1.  删除网关的secret，并创建一个新的secret来修改入口网关的凭据。
+
+    {{< text bash >}}
+    $ kubectl -n istio-system delete secret httpbin-credential
+    {{< /text >}}
+
+    {{< text bash >}}
+    $ mkdir new_certificates
+    $ openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -subj '/O=example Inc./CN=example.com' -keyout new_certificates/example.com.key -out new_certificates/example.com.crt
+    $ openssl req -out new_certificates/httpbin.example.com.csr -newkey rsa:2048 -nodes -keyout new_certificates/httpbin.example.com.key -subj "/CN=httpbin.example.com/O=httpbin organization"
+    $ openssl x509 -req -days 365 -CA new_certificates/example.com.crt -CAkey new_certificates/example.com.key -set_serial 0 -in new_certificates/httpbin.example.com.csr -out new_certificates/httpbin.example.com.crt
+    $ kubectl create -n istio-system secret tls httpbin-credential \
+    --key=new_certificates/httpbin.example.com.key \
+    --cert=new_certificates/httpbin.example.com.crt
+    {{< /text >}}
+
+1.  `curl` 使用新证书链访问 `httpbin` 服务：
+
+    {{< text bash >}}
+    $ curl -v -HHost:httpbin.example.com --resolve "httpbin.example.com:$SECURE_INGRESS_PORT:$INGRESS_HOST" \
+    --cacert new_certificates/example.com.crt "https://httpbin.example.com:$SECURE_INGRESS_PORT/status/418"

+          \_     _/
+            `"""`
+    {{< /text >}}
+
+1. 如果使用先前的证书链访问httpbin，将返回失败。
+
+    {{< text bash >}}
+    $ curl -v -HHost:httpbin.example.com --resolve "httpbin.example.com:$SECURE_INGRESS_PORT:$INGRESS_HOST" \

+### 为多个主机配置TLS入口网关 {#configure-a-TLS-ingress-gateway-for-multiple-hosts}
+
+您可以为多个主机（例如 `httpbin.example.com` 和 `helloworld-v1.example.com` ）配置入口网关。入口网关检索与特定凭据名称相对应的唯一凭据。
+
+1.  要恢复httpbin的凭据，请删除secret并重新创建。
+
+    {{< text bash >}}
+    $ kubectl -n istio-system delete secret httpbin-credential
+    $ kubectl create -n istio-system secret tls httpbin-credential \

+    EOF
+    {{< /text >}}
+
+1.  配置网关的流量路由。定义相应的虚拟服务。

+### 配置双向TLS入口网关 {#configure-a-mutual-TLS-ingress-gateway}
+
+您可以扩展网关的定义以支持[双向TLS](https://en.wikipedia.org/wiki/Mutual_authentication)。删除入口网关的secret并创建一个新的，以更改入口网关的凭据。服务器使用CA证书来验证其客户端，并且必须使用名称 `cacert` 来持有CA证书。

+{{< /text >}}
+
+1. 更改网关的定义, 将TLS模式设置为 `MUTUAL` 。
+
+    {{< text bash >}}
+    $ cat <<EOF | kubectl apply -f -

+       hosts:

+    EOF
+    {{< /text >}}
+
+1. 尝试使用先前的方法发送HTTPS请求，并查看失败的详情：

+    {{< /text >}}
+
+1.  生成客户端证书和私钥：
+
+    {{< text bash >}}
+    $ openssl req -out client.example.com.csr -newkey rsa:2048 -nodes -keyout client.example.com.key -subj "/CN=client.example.com/O=client organization"
+    $ openssl x509 -req -days 365 -CA example.com.crt -CAkey example.com.key -set_serial 1 -in client.example.com.csr -out client.example.com.crt
+    {{< /text >}}
+
+1. 重新发送带客户端证书和私钥的 `curl` 请求。使用--cert标志传递客户端证书，使用--key标志传递私钥。
+
+    {{< text bash >}}
+    $ curl -v -HHost:httpbin.example.com --resolve "httpbin.example.com:$SECURE_INGRESS_PORT:$INGRESS_HOST" \
+    --cacert example.com.crt --cert client.example.com.crt --key client.example.com.key \
+    "https://httpbin.example.com:$SECURE_INGRESS_PORT/status/418"

+          \_     _/
+            `"""`
+    {{< /text >}}
+
+Istio支持读取不同的Secret格式，以支持与各种工具（例如[cert-manager](/zh/docs/ops/integrations/certmanager/))的集成：
+
+* 如上所述，包含 `tls.key` 和 `tls.crt` 的TLS secret。对于双向TLS，可以使用 `ca.crt` 密钥。
+* 包含 `key` 和 `cert` 的通用Secret。对于双向TLS，可以使用 `cacert` 密钥。
+* 包含 `key` 和 `cert` 的通用Secret。对于双向TLS，还可以单独设置名为 `<secret>-cacert` 的通用secret，该secret含 `cacert` 密钥。例如，`httpbin-credential` 包含 `key` 和 `cert`，而 `httpbin-credential-cacert` 包含 `cacert`。
+
+## Troubleshooting {#troubleshooting}
+
+*   检查 `INGRESS_HOST` 和 `SECURE_INGRESS_PORT` 环境变量的值。核实以下命令的输出，确保它们具有有效值：
+
+    {{< text bash >}}
+    $ kubectl get svc -n istio-system
+    $ echo "INGRESS_HOST=$INGRESS_HOST, SECURE_INGRESS_PORT=$SECURE_INGRESS_PORT"
+    {{< /text >}}
+
+*   检查 `istio-ingressgateway` 控制器的日志中是否有错误消息：
+
+    {{< text bash >}}
+    $ kubectl logs -n istio-system "$(kubectl get pod -l istio=ingressgateway \
+    -n istio-system -o jsonpath='{.items[0].metadata.name}')"
+    {{< /text >}}
+
+*   如果使用macOS，请按照[准备工作](#before-you-begin)部分中的说明，验证您正在使用通过[LibreSSL](http://www.libressl.org)库编译的curl。
+
+*   验证secret是否已在 `istio-system` 命名空间中成功创建:
+
+    {{< text bash >}}
+    $ kubectl -n istio-system get secrets
+    {{< /text >}}
+
+    `httpbin-credential` 和 `helloworld-credential` 应该显示在secret列表中。
+
+*   检查日志以确认入口网关代理已将密钥/证书对推送到入口网关。
+
+    {{< text bash >}}
+    $ kubectl logs -n istio-system "$(kubectl get pod -l istio=ingressgateway \
+    -n istio-system -o jsonpath='{.items[0].metadata.name}')"
+    {{< /text >}}
+
+    日志应显示已添加`httpbin-credential` secret。如果使用双向TLS，则还应显示 `httpbin-credential-cacert` secret。验证日志是否显示网关代理接收到来自入口网关的SDS请求（资源名称为 `httpbin-credential`），且入口网关已获得密钥/证书对。如果使用双向TLS，则日志应显示密钥/证书已发送到入口网关，网关代理已收到带有 `httpbin-credential-cacert`资源名称的SDS请求，并且入口网关已获得根证书。
+
+## 清除 {#cleanup}
+
+1.  删除网关配置，虚拟服务定义和secret：
+
+    {{< text bash >}}
+    $ kubectl delete gateway mygateway
+    $ kubectl delete virtualservice httpbin
