java - 在 docker 容器内使用 headless chrome 运行 gauge java 规范

Question

我正在尝试在 docker 容器内使用 headless Chrome 运行一组仪表规范。

我尝试像这样设置 Dockerfile:

FROM maven:latest

RUN apt-get update && apt-get install -q -y unzip curl

ENV DEBIAN_FRONTEND=noninteractive

# requirements for chrome headless

apt-get update &&\

rm -rf /var/lib/apt/lists/*


# Install Google Chrome
RUN curl -sS -o - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - && \
    echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list && \
    apt-get -yqq update && \
    apt-get -yqq install google-chrome-stable && \
    rm -rf /var/lib/apt/lists/*

# Install gauge
RUN apt-get install unzip
RUN curl -L https://github.com/getgauge/gauge/releases/download/v1.0.5/gauge-1.0.5-linux.x86_64.zip -o /gauge-1.0.5-linux.x86_64.zip
RUN unzip -o gauge-1.0.5-linux.x86_64.zip -d /usr/local/bin

# Install gauge plugins
RUN gauge install java && \
    gauge install screenshot

ENTRYPOINT ["mvn"]

注意:这里有少量专有内容我必须删除，但这应该不会产生影响。

另请注意，我工作的 CI 系统负责处理很多事情，例如将卷安装到容器中，从 git 获取存储库，分配端口等。

当 CI 系统使用此容器运行仪表规范时，它们都会失败并出现如下错误:

看来 headless chrome 实例甚至没有启动。但是，我无法弄清楚为什么。

Answer 1

尝试将 --no-sandbox 选项传递给 chromedriver 实例。

示例:

   ChromeOptions options = new ChromeOptions();
   options.addArguments(“--no-sandbox”);
   new ChromeDriver(options);
