在 Alpine docker 容器中运行 geckodriver [英] Running geckodriver in an Alpine docker container
问题描述
我正在尝试在 Alpine 3.10 docker 容器中运行 GeckoDriver v0.26.0，特别是 python:3.6.6-alpine3.10.
I'm trying to run GeckoDriver v0.26.0 inside an Alpine 3.10 docker container, specifically python:3.6.6-alpine3.10.
在弄清楚一些事情之后，我碰壁了:
After figuring some things out, I've hit a wall:
/ # geckodriver --version
Error relocating /usr/bin/geckodriver: __register_atfork: symbol not found
Error relocating /usr/bin/geckodriver: __res_init: symbol not found
我错过了什么?
首先启动 docker 容器:
First spin up the docker container:
docker run -it python:3.6.9-alpine3.10 /bin/sh
然后尝试安装 GeckoDriver
Then try installing GeckoDriver
/ # wget https://github.com/mozilla/geckodriver/releases/download/v0.26.0/geckodriver-v0.26.0-linux64.tar.gz
/ # tar -zxf geckodriver-v0.26.0-linux64.tar.gz -C /usr/bin
/ # geckodriver --version
/bin/sh: geckodriver: not found.
真的吗?但我刚刚提取了它......嗯......好吧.它提取正确吗?$PATH 是否正确?
Really? but I just extracted it... Hmm... OK. Did it extract correctly? Is $PATH correct?
/ # ls -lah /usr/bin/geckodriver
-rwxr-xr-x 1 1000 1000 6.7M Oct 12 10:19 /usr/bin/geckodriver
/ # echo $PATH
/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
是的.好的，让我们谷歌一下.好吧，也许我应该检查file信息.默认情况下，Alpine 没有.
Yes. OK, Let's google things. Well perhaps I should check the file info. Alpine doesn't have that by default.

同一问题的答案 说要检查 /lib64/ld-linux-x86-64.so.2:
/ # ls /lib64
ls: /lib64: No such file or directory
不见了.好的，我们如何得到它?Alpine package repo 说它是 libc6-compat 的一部分.很酷的安装它，一切都会工作......对吗?
Missing. OK, how do we get that? The Alpine package repo says it's part of libc6-compat. Cool install that and things will work... right?

...好吧，至少它现在将其识别为可执行文件...好的，所以我们需要 libgcc_s.so.1.在 libgcc 中.有道理.
... Well at least it recognizes it as an executable file now... OK, so we need libgcc_s.so.1. That's in libgcc. Makes sense.

什么?我们在 /lib64 中有 ld-linux-x86-64.so.2，它在哪里看?我确实注意到 gcompat 包为 /lib/ld-linux-x86-64.so.2，也许它在那里寻找?
What? We have ld-linux-x86-64.so.2 in /lib64, where's it looking? I did notice that the gcompat package as /lib/ld-linux-x86-64.so.2, maybe it's looking there?

这就是我所在的地方.谷歌搜索 __register_atfork 和 __res_init 不会返回任何有用的东西.
And that's where I'm at. Googling for __register_atfork and __res_init don't return anything useful.
推荐答案
所以问题的根本原因似乎是 Alpine 使用了 musl libc 和 GeckoDriver(间接)使用 glibc.
So the root cause of the issue appears to be that Alpine uses musl libc and GeckoDriver (indirectly) uses glibc.
SGerrand 有一个很棒的 glibc 兼容层包，用于 Alpine Linux使用.
SGerrand has a great glibc compatibility layer package for Alpine Linux which we'll make use of.

# And of course we need Firefox if we actually want to *use* GeckoDriver
apk add firefox-esr=60.9.0-r0
# Then install GeckoDriver
wget https://github.com/mozilla/geckodriver/releases/download/v0.26.0/geckodriver-v0.26.0-linux64.tar.gz

注意事项:
- 仅在
python:3.6.9-alpine3.10docker 镜像上测试. - Alpine 3.10 仅具有 Firefox ESR 60.幸运的是 GeckoDriver v0.26 具有最低版本的 FireFox 60.
- Alpine Edge 分支有 Firefox-ESR 86 和 Firefox 70.
- Only tested on the
python:3.6.9-alpine3.10docker image. - Alpine 3.10 only has Firefox ESR 60. Luckily GeckoDriver v0.26 has a minimum version of FireFox 60.
- The Alpine Edge branch has Firefox-ESR 86 and Firefox 70.
