Question

Docker 映像 selenium/standalone-firefox:3.4.0-chromium 是否设计为同时包含 Firefox 和 Chrome 驱动程序？

现在我有这个 Dockerfile 来构建一个 selenium 服务器：

FROM selenium/standalone-firefox:3.4.0-chromium
USER root
ENV NODE_ENV test
RUN mkdir -p /usr/local/cdt-tests/csv-data
COPY ./csv-data /usr/local/cdt-tests/csv-data
USER seluser

它适用于 Firefox，但我收到了这个与 Chrome 相关的错误：

所以我唯一的猜测是 Docker 映像实际上并未设计为包含 Google Chrome Selenium 驱动程序？那么为什么它的图像名称中有“铬”呢？困惑。

Answer 1

没有。在这种情况下，“铬”是一个版本指示符。查看https://hub.docker.com/r/selenium/standalone-firefox/tags/，您会看到铋、锑、砹、铜。该项目显然使用元素作为版本或构建标识符。
