Dokcerfile如何在使用(RUN yum -y install vim)时配置yum源
时间: 2023-05-15 12:05:28 浏览: 123
您可以在 Dockerfile 中使用以下命令来配置 yum 源并安装 vim:
```
RUN yum install -y wget && \
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo && \
yum install -y vim
```
这将使用 wget 命令下载阿里云的 CentOS 7 yum 源,并使用 yum 安装 vim。

这是一个 Docker 构建过程的输出,其中包括加载 .dockerignore 文件、加载 Dockerfile、从 Docker Hub 上下载 centos 镜像、安装 vim 软件包等步骤。但是在安装 vim 时出现了错误,可能是由于网络连接问题或者 yum 源配置问题导致的。

这段代码的作用是在 Ubuntu 或者 CentOS 系统中安装 Docker。代码中定义了两个函数 `install_docker_in_ubuntu` 和 `install_docker_in_centos`,分别用来在 Ubuntu 和 CentOS 系统中安装 Docker。在主函数中,通过检查系统名称来确定是在 Ubuntu 还是 CentOS 系统中运行脚本,然后调用相应的安装函数来安装 Docker。
代码的语法看起来没有问题,也没有出现之前提到的语法错误。如果你遇到了问题,可以把出错的信息贴出来,让我来帮你分析一下。
