我有以下用于 zookeeper 的 Dockerfile,我正在尝试为它创建一个图像,但它给了我一个错误。我最近开始使用 Docker,并开始使用 Zookeeper 设置,所以我无法理解。这个错误是什么意思?
FROM ubuntu:trusty

下面是我得到的错误:

/bin/sh: 1: apk: not found
The command '/bin/sh -c apk add --no-cache bash su-exec' returned a non-zero code: 127
我在这里做错了什么吗?为什么找不到
apk
? 最佳答案
由于 larsks mentions , apk
适用于 Alpine 发行版,您选择了 FROM ubuntu:trusty
,它是基于 Debian 的 apt-get
命令。将您的 FROM 行更改为 FROM alpine:3.4
以切换到具有 apk
支持的基于 Alpine 的图像。
关于ubuntu -/bin/sh : 1: apk: not found while creating docker image,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/40445243/
