Docker:将 Linux korn Shell 添加到现有容器

Question

我对 docker 很陌生，我想将 Linux Korn Shell 添加到现有容器中。

我使用了这个命令:

  yum install ksh 

我收到这些错误:

    fastesmirror
    Loading mirror speeds from cached hostfile
    * epel: fedora-archive.ip-connect.vn.ua
    * epel-debuginfo: fedora-archive.mirror.liquidtelecom.com
    * epel-source: fedora-archive.mirror.liquidtelecom.com
    Setting up Install Process
    No package ksh available.
    Nothing to do

有人可以帮我安装 ksh 吗？

谢谢 !

PS:这是一个 Ubuntu 8.3.0

Answer 1

在 Ubuntu 上，您需要使用 apt-get 而不是 yum 来安装任何软件包。所以要安装ksh，需要使用命令apt-get -y install ksh .这是我的 Dockerfile-

FROM ubuntu:18.04

RUN apt-get -qqy update && apt-get dist-upgrade -qqy && apt-get -y install ksh

这是我的容器的输出，显示确实安装了 ksh -

root@qa6:~/amitp/p1# docker run -it 948453249b61 bash
root@ea237be38b71:/# ksh
# echo $0
ksh
#

更新 :
以上是在构建容器镜像时安装了 ksh 的容器。如果您有任何现有的 Ubuntu 容器正在运行，请使用如下所示的类似命令安装 ksh-

root@qa6:~/amitp/p1# docker run -it 72300a873c2c bash
root@5c844bb2b7ad:/# ksh
bash: ksh: command not found
root@5c844bb2b7ad:/# apt-get -qqy update && apt-get dist-upgrade -qqy && apt-get -y install ksh
