Alpine安装telnet

物理机centos 安装netstat

yum -y install net-tools

Alpine镜像中的telnet在3.7版本后被转移至busybox-extras包中，需要使用apk单独安装。

执行命令

apk update
apk add busybox-extras

出现报错

bash-5.0$  apk update
ERROR: Unable to lock database: Permission denied
ERROR: Failed to open apk database: Permission denied

用root方式进入容器

bash-5.0# apk update
