Ubuntu Server 配置

1、配置镜像点

cd /etc/apt
cp sources.list sources.list.bak
vim sources.list

2、Ubuntu 20.04，阿里云

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

3、安装Docker

apt-get remove docker docker-engine docker.io containerd runc

apt-get update

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

　这一步如果出错，可以先按下面的安装依赖项

apt-get install 
    apt-transport-https 
    ca-certificates 
    curl 
    gnupg-agent 
    software-properties-common

4、添加 docker镜像加速

sudo vim /etc/docker/daemon.json

　　

{
  "registry-mirrors": ["https://xxxxxx.mirror.aliyuncs.com"]
}

　　

sudo systemctl daemon-reload

sudo systemctl restart docker

5、安装 .net

hub地址 .NET - Docker Hub

.net 5 sdk - docker

docker pull mcr.microsoft.com/dotnet/sdk:5.0

　　

aspnet 5 - docker

dotnet-dcoker 项目地址:GitHub - dotnet/dotnet-docker: Docker images for .NET Core and the .NET Core Tools.

docker pull mcr.microsoft.com/dotnet/aspnet:5.0

6、结果

root@xxx:/etc/apt# docker images
