/bin/sh:find:在rockylinux:8的dockerfile中找不到命令

Question

我在os:rockylinux:8中创建了dockerfile。获取错误：/bin/sh: find: command not found

Dockerfile:

FROM rockylinux:8 AS builder
RUN mkdir /usr/share/dashboards
WORKDIR /usr/share/dashboards
RUN find /usr/share/dashboards

错误-

/bin/sh: find: command not found
The command '/bin/sh -c find /usr/share/dashboards' returned a non-zero code: 127

Answer 1

find命令不包含在基本rockylinux映像中，您必须安装findutils包才能使用它。

我刚刚测试过，这个有效：

FROM rockylinux:8 AS builder
RUN yum install -y findutils
WORKDIR /usr/share/dashboards
RUN find /usr/share/dashboards

现在，最好的做法是在构建开始时更新图像，这样你就可以获得最新的软件包和安全补丁，所以我实际上会这样做：

FROM rockylinux:8 AS builder
RUN yum -y update
RUN yum install -y findutils
WORKDIR /usr/share/dashboards
RUN find /usr/share/dashboards

稍后，您可以通过将两个yum命令放在同一条RUN指令中进行优化，并可能清理缓存，但这应该足以让您开始。

PS：在他们的编辑中，@DavidMaze指出Dockerfile中的mkdir行是多余的，因为WORKDIR指令已经创建了目录。
