第一章：docker环境安装

1.更新数据源：

  拿到新的服务器，第一件事情，更新数据源，ubuntu系统可以通过执行如下指令：
1

echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse' >> /etc/apt/sources.list && \

echo 'deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse' >> /etc/apt/sources.list && \

apt-get update -y && \

apt-get clean

debian系统如下：

cat >/etc/apt/sources.list <<EOF
deb http://mirrors.aliyun.com/debian stable main contrib non-free
deb http://mirrors.aliyun.com/debian stable-proposed-updates main contrib non-free
deb http://mirrors.aliyun.com/debian stable-updates main contrib non-free
deb-src http://mirrors.aliyun.com/debian stable main contrib non-free
deb-src http://mirrors.aliyun.com/debian stable-proposed-updates main contrib non-free
deb-src http://mirrors.aliyun.com/debian stable-updates main contrib non-free
EOF

更新：

root@xyxypi:apt update
root@xyxypi:~# apt upgrade

注意:如果执行失败，查一下内核

root@aml://# sudo dpkg  --print-architecture
arm64

如果返回时arm架构，是因为Ubuntu 18.04 使用apt-get 华为源支持 arm64 鲲鹏处理器，而阿里云163等等的，都不支持arm64，所以需要如下指令更新源:

wget -O /etc/apt/sources.list https://repo.huaweicloud.com/repository/conf/Ubuntu-Ports-bionic.list
apt-get update

2.安装 Docker

>> curl -fsSL get.docker.com -o get-docker.sh

>> sh get-docker.sh --mirror AzureChinaCloud

如果是debian 系统，则参考：
debian duocker安装

执行成功之后docker即安装成功，此时要更新docker镜像源daemon.json 文件
执行cd //  退到服务器主目录，执行 find -name "daemon.json" 找到自己的 daemon.json文件，一般在/etc/docker/daemon.json 目录下，然后执行vi /etc/docker/daemon.json 修改配置文件如下：（注意：insecure-registries 是后续要用到的远程镜像仓库地址）

     "native.cgroupdriver=systemd"
 ],
 "log-driver": "json-file",
 "log-opts": {
     "max-size": "100m"
 },
 "registry-mirrors": [
     "http://hub-mirror.c.163.com",
     "https://dockerhub.azk8s.cn"
 ],
 "insecure-registries": [
     "*.*.*.*:7000"

执行 docker version 即可看到如下docker 信息，表示安装正常
1
