这是一个企业网络，因此我们让 Zscaler 充当 MITM。

为什么我认为容器中的卷曲应该可以正常工作？因为我将所有相同的证书目录从主机挂载到容器中：
- /etc/ssl
- /usr/local/share/ca-证书
- /usr/share/ca-证书
因此，大概容器“看到”与主机相同的证书。那么为什么它不起作用呢？
编辑1
这是一个注入了 Zscaler 证书的企业网络。如果您不在类似的环境中，您将无法干净地重现它。我的问题是概念性的 - 我似乎通过各种安装在容器中复制我的主机环境，但当主机通过时容器会失败。
编辑2
为了进行实验，我切换到以下 Dockerfile：
FROM nginxinc/nginx-unprivileged:1.23.3-alpine-slim
USER 0
ARG chip_user_pwd
RUN apk update && \
apk add --no-cache sudo curl busybox-extras bind-tools nmap-ncat openssl netcat-openbsd openssh git strace && \
adduser -u 1000 -D chip && \
echo "chip:$chip_user_pwd" | chpasswd && \
echo "chip ALL=(ALL) ALL" > /etc/sudoers.d/chip && \
chgrp -R chip /etc/nginx/conf.d && \
chmod 0440 /etc/sudoers.d/chip
COPY default.conf.template /etc/nginx/templates/default.conf.template
USER 101
（我用它来解决问题）
运行容器的命令行是：
docker run --cap-add=SYS_PTRACE -d -v /etc/ssl:/etc/ssl -v /usr/local/share/ca-certificates:/usr/local/share/ca-certificates -v /usr/share/ca-certificates:/usr/share/ca-certificates OurACR.azurecr.io/chip/toolbox sleep 1d
它显示与卷曲图像相同的行为。我跑了strace（感谢https://jvns.ca/blog/2020/04/29/why-strace-doesnt-work-in-docker/有关说明）在容器和主机上。
两者都读自/etc/ssl/certs/ca-certificates.crt:
然而，一旦读完，他们就会做不同的事情：
最后，在主机上运行的进程开始读取 ZScaler 证书之一，而在容器上运行的进程我不知道是什么：
在哪里：
mark@L-R910LPKW:~$ ls -l /etc/ssl/certs/f36a1d00.0
lrwxrwxrwx 1 root root 54 Apr 21 16:46 /etc/ssl/certs/f36a1d00.0 -> 'Zscaler_Intermediate_Root_CA_=zscalertwo.net=_=t=_.pem'
mark@L-R910LPKW:~$
因为 strace 包含很多噪音。很想知道如何以有意义的方式减少它。
忘记说了。主机加载/lib/x86_64-linux-gnu/libssl.so.3，docker 容器加载/lib/libssl.so.3。也许这很重要。

该curlimages/curl映像未将curl配置为使用CA目录路径，并且还使用默认的CA证书捆绑路径/cacert.pem.因此/etc/ssl/certs，curl 不会检查绑定您的目录（通常可能在您的系统上运行）。
您可以通过传递例如-v /etc/ssl/certs/ca-certificates.crt:/cacert.pem作为 docker 参数（如果/etc/ssl/certs/ca-certificates.crt包含所有 CA 证书）将证书包绑定到预期位置，或者在您已绑定的情况下/etc/ssl:/etc/ssl，您可以--capath /etc/ssl/certs作为curl 参数传递。
