Question

我正在尝试在docker容器上安装ping和ifconfig。但是，当我运行此dockerfile时，出现以下错误：

E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/libc/libcap2/libcap2_2.25-1.2_amd64.deb  Could not connect to archive.ubuntu.com:80 (91.189.88.142). - connect (111: Connection refused) Could not connect to archive.ubuntu.com:80 (91.189.88.152). - connect (111: Connection refused)

The command '/bin/sh -c apt-get update && apt-get install -y iputils-ping' returned a non-zero code: 100

这是我用来构建映像的Dockerfile：

FROM openanalytics/r-base

#iptools (ping, ifconfig)
RUN apt-get update && apt-get install -y iputils-ping
RUN apt-get install net-tools

安装iputils-ping和net-tools的命令是否错误？如果我注释掉iputils行并且仅单独安装Net-tools，则会收到类似的错误。

由于此行RUN curl https://packages.microsoft.com/config/ubuntu/18.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

，此操作失败

您要使用Microsoft源代码替换整个文件，>运算符将替换文件，您需要使用>>附加到文件，因此将命令更改为RUN curl https://packages.microsoft.com/config/ubuntu/18.04/prod.list >> /etc/apt/sources.list.d/mssql-release.list

>>附加到文件或创建文件（如果文件不存在）。 >覆盖文件（如果存在）或创建文件（如果不存在）。

这就是为什么它找不到软件包。源被上一条命令删除。

此外，您只需在添加新资源后一次执行apt-get更新。

并且您在安装ping的命令中缺少-y。

正确的命令：

RUN apt-get install net-tools -y

希望这会有所帮助。评论是否需要其他帮助。

无法在dockerfile中安装iputils和net-tools
