我有一个非常简单的docker容器,可以安装' google-chrome-stable'按照these instructions。
在容器内部,我无法启动并访问调试服务器:
# start chrome in debug mode
$ google-chrome-stable --no-sandbox --remote-debugging-port=9222
# verify that I can reach the debugging server
$ curl 127.0.0.1:9222
curl: (7) Failed to connect to localhost port 9222: Connection refused
在容器外部(OSX 10.12.6),相同的过程可以正常工作:
# start chrome in debug mode
$ chrome --no-sandbox --remote-debugging-port=9222
# verify that I can reach the debugging server
$ curl localhost:9222
curl localhost:9222
<html>
<head>
<title>Inspectable pages</title>
...
必须有一些我失踪的东西,因为即使环境不同,它们似乎是相同的工作流程。
有人可以说明这里发生了什么吗?
::使用更多调试信息进行更新::
使用--enable-logging --v=1
标志运行命令,我得到这些日志[没有一个看起来很了不起]:

答案 0 :(得分:-1)
事实证明,在没有--headless
标志的情况下,我所做的事情已经完成。
# start chrome in debug mode
$ google-chrome-stable --no-sandbox --remote-debugging-port=9222 --headless
# debugging server works as expected
$ curl 127.0.0.1:9222
