高山无法满足的约束：缺少包裹 [英] Alpine unsatisfiable constraints: missing packages

问题描述

我正在尝试基于 alpine：3.7 创建一个docker映像，但是在安装某些 apk add 。

I am trying to create a docker image based on alpine:3.7, but I get errors while installing some packages with apk add.

示例：

ERROR: unsatisfiable constraints:
  apache2-suexec (missing):
    required by: world[apache2-suexec-custom]
  host (missing):
    required by: world[host]
  lpr (missing):
    required by: world[lpr]
  time (missing):
    required by: world[time]

原因是这些软件包在高山存储库中尚不存在。我该如何解决这些问题？有任何可从中下载它们的存储库吗？

The cause is that these packages do not exist in alpine repositories yet. How can I solve these issues? Is there any repository from which I can download them?

我正在使用此行

FROM alpine:3.7

RUN apk update \
    && apk upgrade \
    && apk --no-cache add --update tcl apache2 apache2-suexec ca-certificates \ 
    apk-tools curl build-base supervisor lpr time dcron host rsync libxml2-utils libxslt

推荐答案

以下软件包存在问题： apache2-suexec ，主机， lpr 和时间

You have an issue with the following packages: apache2-suexec, host, lpr and time.

Alpine的软件包结构不同于主要的Linux操作系统：

Alpine has some other package structure than main Linux OSs:

• apache2-suexec 是 apache2 软件包的一部分；


• host 是 bind-tools 软件包的一部分；


• lpr 是 cups-client 软件包的一部分；


• 时间已经在高山图像中了。它使用 busybox 的 time 实用工具。

• apache2-suexec is a part of apache2 package;
• host is a part of bind-tools package;
• lpr is a part of cups-client package;
• time is already in alpine image. It uses busybox's time utility.

因此，最终的 Dockerfile 是：

FROM alpine:3.7

RUN apk update \
    && apk upgrade \
    && apk --no-cache add --update tcl apache2 ca-certificates \ 
    apk-tools curl build-base supervisor cups-client dcron bind-tools rsync libxml2-utils libxslt
