如何在 Ubuntu Docker 镜像上安装 /etc/services

当你使用基于 Ubuntu 的 docker 镜像如

Dockerfile

FROM ubuntu:22.04

FROM ubuntu:22.04

默认情况下，/etc/services 未安装。

但是，你可以通过安装 netbase apt 包来轻松安装它：

Dockerfile

# netbase provides /etc/services
RUN apt update && apt install -y netbase && rm -rf /var/lib/apt/lists/*

# netbase provides /etc/services
RUN apt update && apt install -y netbase && rm -rf /var/lib/apt/lists/*
