我们计划在项目中使用Envoy，因此我开始在Envoy github上提供的简单示例中弄混，而我的公司代理也遇到了困难。
我尝试的第一件事很简单，就是通过Envoy服务一个网站www.onisep.fr(我故意选择了没有HTTPS的网站)。
我的单个Envoy docker 形象:
FROM envoyproxy/envoy:latest
ENV HTTP_PROXY http://mycompany.proxy:8080
ENV HTTPS_PROXY http://mycompany.proxy:8080
CMD apt-get update && apt-get -y install curl -y
CMD /usr/local/bin/envoy -c /etc/front-envoy.yaml --service-cluster front-proxy --log-level trace
注意:注意代理配置
我的特使配置:
static_resources:
listeners:
- address:
socket_address:
address: 0.0.0.0
port_value: 80
filter_chains:
- filters:
- name: envoy.http_connection_manager

route_config:

virtual_hosts:

typed_config: {}
clusters:

connect_timeout: 10.0s
lb_policy: round_robin

port_value: 80
admin:
access_log_path: "/dev/null"
address:
socket_address:
address: 0.0.0.0
port_value: 8001
当我转发到公司网络上的网站时，该配置工作正常。但是，一旦我使用该网络之外的地址，就会遇到问题:
在我的浏览器中:

显然我的公司代理是问题所在，Envoy无法访问该网站。
我没有找到有关Envoy中Internet代理配置的任何资源。
我缺少什么配置？
谢谢
最佳答案
当您使用单个docker镜像进行测试时，建议您传递docker容器IP。请按照以下示例更改配置。
〜docker ps -q | xargs -n 1 docker inspect --format'{{range .NetworkSettings.Networks}} {{。IPAddress}} {{end}} {{.Config.Hostname}} {{.Config.Image}}'| sed's / // /'
=> 172.19.0.2 e7b03f46f33e parjun8840 / flaskapp:v3
更改文件内容: front-envoy.yaml
clusters:
- name: onisep
connect_timeout: 10.0s
lb_policy: round_robin
type: STATIC
hosts:
socket_address:
address: 172.19.0.2
port_value: 80
请告诉我，是否对您有用？
