我有一个docker-compose.yml文件，其中包含众所周知的环境变量，可以访问我们的公司代理：
---
version: '2.2'
# adapted from:
# https://github.com/SeleniumHQ/docker-selenium/wiki/Getting-Started-with-Docker-Compose
# docker-compose --force-recreate
services:
chrome:
privileged: True
image: "selenium/standalone-chrome:3.11.0"
ports:
- "4444:4444"
volumes:
- /dev/shm:/dev/shm
environment:
- TZ="UT"
- http_proxy=http://proxy.lan:8080
- https_proxy=http://proxy.lan:8080
- no_proxy=
#- SE_OPTS=-Dhttp.proxyHost=proxy.lan -Dhttp.proxyPort=8080
network_mode: host
当我在容器中运行wget时，代理将按预期使用。

但是，当我尝试使用SE_OPTS="-Dhttp.proxyHost=proxy.lan -Dhttp.proxyPort=8080"运行容器时，我看到了一个堆栈跟踪：
Exception in thread "main" com.beust.jcommander.ParameterException: Was passed main parameter '"-Dhttp.proxyHost=proxy.lan' but no main parameter was defined in your arg class.
有一个unmerged PR，但我担心在Se dev中可能感觉不到在企业环境中使用代理进行测试的紧迫性。也许有另一种解决方案。
