命令 '/bin/sh -c apk add .... 返回一个非零代码：6

Question

docker build 命令没有构建我正在尝试制作的 docker 机器。我搜索了整个网络，我找不到答案。以下是我的dockerfile。我认为问题始于 fetch http://dl-cdn.alpinelinux.org/alpine/v3.4/main/x86_64/APKINDEX.tar.gz

FROM python:3.5-alpine
MAINTAINER ******* <code@******.com>


ENV INSTALL_PATH /web
RUN mkdir -p ${INSTALL_PATH}
COPY . ${INSTALL_PATH}
WORKDIR ${INSTALL_PATH}

RUN apk add --no-cache --virtual .build-deps build-base libffi-dev postgresql-dev uwsgi-python supervisor \
        && pip install --trusted-host github.com --process-dependency-links -e . \
        && find /usr/local \( -type d -a -name test -o -name tests \) \
           -o \( -type f -a -name '*.pyc' -o -name '*.pyo' \) -exec rm -rf '{}' + \
        && runDeps="$(scanelf --needed --nobanner --recursive /usr/local \
           | awk '{ gsub(/,/, "\nso:", $2); print "so:" $2 }' \
           | sort -u | xargs -r apk info --installed | sort -u \
        )" \
        && apk add --virtual .rundeps $runDeps && apk del .build-deps

输出如下：

Answer 1

对我来说，通过关闭我的 VPN 解决了​​这个问题。

Answer 2

在获取过程中，dns 名称服务器无法解析地址。原因可能是有防火墙

Ubuntu 在 /etc/default/docker 文件中有 google dns 服务器

DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"

这里有更多解决dns问题的细节Docker - Network calls fail during image build on corporate network

Answer 3

分离每个命令，看看它们中的哪一个是导致问题的确切原因。而不是使用 && 一个接一个地连接。将带有apk add 的 RUN 命令仅用于一个包，然后以相同的方式为另一个包。

通过这种方式，您将看到究竟是哪一个导致了问题。

这仅用于“调试”。解决问题后，您可以再次将它们放在一起。
