我有以下YAML文件:
seleniumhub:
image: selenium/hub
ports:
- 4444:4444
firefoxnode:
image: selenium/node-firefox-debug
ports:
- 4577
links:
- seleniumhub:hub
expose:
- "5900"
chromenode:
image : selenium/node-chrome-debug
ports:
- 4578
links:
- seleniumhub:hub
expose:
- "5900"
docker ps:
time="2017-04-01T17:57:44+03:00" level=info msg="Unable to use system certificate pool: crypto/x509: system root pool is not available on Windows"
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

7d95d3e73016 selenium/hub "/opt/bin/entry_po..." 7 seconds ago Up 6 seconds 0.0.0.0:4444->4444/tcp dockercompose_seleniumhub_1
但每当我在Docker快速启动终端中运行以下命令时:
docker port 9d2ccb193b54 5900
我得到了以下内容:
错误:没有为9d2ccb193b54发布公共端口'5900 / tcp'
我无法通过VNC连接到节点机器

firefoxnode
尝试此配置:
image: selenium/node-firefox-debug
ports:
- 4577
- 5900
links:
- seleniumhub:hub
expose:
- "5900"
expose
不会将端口发布到主机,只能访问链接的服务。它适用于容器间通信。 ports
会将该端口暴露给主机。
答案 1 :(得分:0)
对于暴露端口,其语法为:
ports:
- "host:container"
在你的情况下:
image: selenium/node-firefox-debug
ports:
- 4577
- "5900:5900"
links:
- seleniumhub:hub
此致
