google-chrome - docker 官方 dind 构建 (docker :latest) with chromiuim

Question

过去两天我一直在尝试在 docker:latest docker 镜像上安装和运行 chromuim。 ( docker 中的 docker )。

我尝试了多个 docker 文件:

from docker:latest

RUN apk add --no-cache python py2-pip curl bash chromuim ttf-freefont xvfb nodejs nodejs-npm udev    
RUN curl -sSL https://sdk.cloud.google.com | bash
ENV PATH $PATH:~/google-cloud-sdk/bin

RUN pip install docker-compose
RUN npm install -g @angular/cli swagger 
ENV CHROME_BIN=/usr/bin/chromium-browser

这安装了不支持 headless 的 chrome 57。
所以我怀疑我可以用 xvbf 运行它，但是运行这个 chrome 失败了:

Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted
[8:8:1124/085514.600081:FATAL:zygote_host_impl_linux.cc(182)] Check failed: ReceiveFixedMessage(fds[0], kZygoteBootMessage, sizeof(kZygoteBootMessage), &boot_pid). 
Aborted (core dumped)

所以我尝试安装 chrome 61(支持 headless )。
但为此，您需要更新 Dockerfile 以使用 edge。
我尝试立即升级/或安装 61。我总是缺少字体。
我得到的最接近的是调整我的 dockerfile 以使用 lighthose 之一

from docker:latest

RUN apk add --no-cache python py2-pip curl bash xvfb nodejs nodejs-npm udev    
RUN curl -sSL https://sdk.cloud.google.com | bash
ENV PATH $PATH:~/google-cloud-sdk/bin

RUN pip install docker-compose
RUN npm install -g @angular/cli swagger 
ENV CHROME_BIN=/usr/bin/chromium-browser

xvfb-chromium.sh (虽然不需要，因为你可以 docker run/bin/bash 进入容器)

#!/bin/sh

_kill_procs() {
  kill -TERM $chromium
  wait $chromium
  kill -TERM $xvfb
}

parameters=$@


# We need to test if /var/run/dbus exists, since script will fail if it does not

[ ! -e /var/run/dbus ] && mkdir /var/run/dbus

/usr/bin/dbus-daemon --system

# Setup a trap to catch SIGTERM and relay it to child processes

# Start Xvfb

printf "Starting xvfb window server..."

while [  1 -gt $xvfb  ]; do printf "..."; sleep 1; done

printf "xvfb started\n\n"

#printf "Starting chromium, with debugger on port $CHROME_DEBUGGING_POST...\n\n"

#wait4ports tcp://127.0.0.1:$CHROME_DEBUGGING_PORT

printf "\n\n==============================\nlaunching lighthouse run\n==============================\n\n"

#wait $chromium
wait $xvfb

然后我得到另一个错误:

Error relocating /usr/lib/chromium/chrome: FT_Set_Default_Properties: symbol not found

不知道如何解决这个问题，任何帮助将不胜感激。

你可以试试这个链接https://github.com/c0b/chrome-in-docker
它从 chrome channel 下载 google-chrome Linux 版本，无论是稳定版，还是 beta 版，或者开发者版；它把 google-chrome 变成了一个 headless 浏览器，
