运行selenium firefox测试时，设备上路径/tmp/rust_mozprofile上没有剩余空间

Question

我使用的是selenium 4-beta3 (但使用selenium 3.14时，我遇到了同样的错误)

接下来是驱动程序配置

Capybara.register_driver :remote do |app|
  caps = Selenium::WebDriver::Remote::Capabilities.firefox(:acceptInsecureCerts = true)
  Capybara::Selenium::Driver.new(
    app,
    browser: :firefox,
    url: "http://selenium-hub:4444/wd/hub",
    capabilities: caps
  )
end

Docker-compose文件摘录：

version: '2'

services:
  firefox:
    depends_on:
    - selenium-hub
    environment:
    - SE_EVENT_BUS_HOST=selenium-hub
    - SE_EVENT_BUS_PUBLISH_PORT=4442
    - SE_EVENT_BUS_SUBSCRIBE_PORT=4443
#    - TMPDIR=/home/seluser/
    image: <via proxy from SeleniumHQ/docker-selenium/node-firefox:4.0.0-beta-3-20210426>
    volumes:
    - /dev/shm:/dev/shm
    ports:
    - 6902:5900
  selenium-hub:
    image: <via proxy from SeleniumHQ/docker-selenium/hub:4.0.0-beta-3-20210426 >
    ports:
    - 4442:4442
    - 4443:4443
    - 4444:4444

无论何时我尝试运行test -它都失败了，firefox日志列出了这个错误：

当我检查火狐docker容器时，/tmp文件夹是空的。

EDIT:

我尝试指向/dev/shm作为tem并分配足够的内存

    environment:
    - TMPDIR=/dev/shm
    shm_size: 4g

它工作了-当查看日志时，我看到firefox webdriver初始化正确，但现在它在/home/seluser/目录中缺少空间

dconf-CRITICAL **: unable to create directory '/home/seluser/.cache/dconf': No space left on device. dconf will not work properly.

已检查我的Docker桌面资源-磁盘映像大小空间不足。我增加了空间，测试开始工作了。
