dotnet 基于 debian 创建一个 docker 的 sdk 镜像

  • 2020 年 3 月 12 日
  • 筆記

我不能用官方的镜像，因为我需要在小伙伴构建的 debian 镜像上面安装 dotnet sdk 用来做构建，其实在 docker 里面需要找到一个个文件，然后复制代码

这是小伙伴做的一个 jenkins 的镜像 jenkins/slave 我需要在这个镜像基础上安装 dotnet 进行构建

FROM jenkins/slave

在安装 dotnet 之前需要通过官方 https://github.com/dotnet/dotnet-docker 找到对应的 docker 文件，这样可以进行复制，可以看到官方是引用下面代码 buildpack-deps:buster-scm 这个库

FROM buildpack-deps:buster-scm

需要找到 buildpack-deps:buster-scm 的代码

找到这个库的代码 https://github.com/docker-library/buildpack-deps/blob/b0fc01aa5e3aed6820d8fed6f3301e0542fbeb36/buster/curl/Dockerfile 可以复制，但是这个库依赖 FROM buildpack-deps:buster-curl 这个库，通过 docker hub 找到 https://github.com/docker-library/buildpack-deps/blob/b0fc01aa5e3aed6820d8fed6f3301e0542fbeb36/buster/curl/Dockerfile 也可以复制

# https://github.com/docker-library/buildpack-deps/blob/b0fc01aa5e3aed6820d8fed6f3301e0542fbeb36/buster/curl/Dockerfile  # FROM debian:buster  RUN apt-get update && apt-get install -y --no-install-recommends           ca-certificates           curl           netbase           wget       && rm -rf /var/lib/apt/lists/*    RUN set -ex;       if ! command -v gpg > /dev/null; then           apt-get update;           apt-get install -y --no-install-recommends               gnupg               dirmngr           ;           rm -rf /var/lib/apt/lists/*;       fi    # FROM buildpack-deps:buster-curl  # https://github.com/docker-library/buildpack-deps/blob/99a1c33fda559272e9322b02a5d778bbd04154e7/buster/scm/Dockerfile  # procps is very common in build systems, and is a reasonably small package  RUN apt-get update && apt-get install -y --no-install-recommends           git           mercurial           openssh-client           subversion                     procps       && rm -rf /var/lib/apt/lists/*

使用 dotnet 官方地址下载速度太慢了，我请了小伙伴帮我下载，然后我将 dotnet-sdk-3.1.102-linux-x64.tar.gz 和 PowerShell.Linux.x64.7.0.0-rc.2.nupkg 放在 docker 文件相同文件夹

接下来是复制 dotnet 的代码

运行 docker build -t dotnet-sdk:3.0.102 . 就可以创建了
