我将应用程序容器化,这是自动化Selenium测试的测试驱动程序。 Selenium服务器(也称为Selenium Hub)运行在另一个Container,以及localhost:4444下的Firefox节点。 但我的应用无法达到它:

我通过docker-compose:
启动了这些容器
version: '2'
services:
hub:
image: selgrid:1.1
ports:
- "4444:4444"
firefox:
#pull latest from docker hub
image: selenium/node-firefox
volumes:
- /dev/urandom:/dev/random
depends_on:
- hub
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=4444
testautomation:
#run testautomation app
image: volumetest
links:
- "hub"
ports:
- "9005:9005"
我想我的docker-compose有一个错误,但我无法弄明白。请帮忙! 顺便说一句:我在Windows 7上运行并使用Docker和Vagrant VM。在我的Vagrantfile中,我将端口4444和9005映射到主机系统。如果我打开本地浏览器并访问localhost:4444,我可以看到selenium网格控制台。为什么它不适用于我的应用容器?
答案 0 :(得分:2)
在您的应用容器localhost
中表示当前容器。因此,您需要使用服务的名称。在您的情况下,hub
所以连接到hub:4444
答案 1 :(得分:0)
移植到docker-compose版本2后,我遇到了同样的问题。 这是我得到的日志
Connect to localhost:4444 [localhost/127.0.0.1] failed: Connection refused
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
以下是docker-compose yml文件的样子:
version: '2'
services:
seleniumhub:
image: selenium/hub
ports:
- 4444:4444
firefoxnode:
image: selenium/node-firefox-debug
ports:
- 5900
environment:
- HUB_PORT_4444_TCP_ADDR=seleniumhub
- HUB_PORT_4444_TCP_PORT=4444
webdrivertests:
image: vodqa/gridtests
volumes:
- ./temp:/usr/src/app/target
environment:
- HUB_PORT_4444_TCP_ADDR=seleniumhub
- HUB_PORT_4444_TCP_PORT=4444
command: bash -c "cd /usr/src/app && mvn test"
在我的测试中,我尝试使用以下方式访问集线器:
new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),desiredCapabilitiesff );
