（1）直接安装（版本较低）
（2）安装高版本

sudo apt -y install apt-transport-https ca-certificates curl software-properties-common

sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $( lsb_release -cs) stable"

sudo add-apt-repository "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu $( lsb_release -cs) stable"
sudo apt -y update
出现以下提示：
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
原因如下：
apt-key is used to manage the list of keys used by apt to authenticate packages. Packages which have been authenticated using these keys are considered trusted.
Use of apt-key is deprecated, except for the use of apt-key del in maintainer scripts to remove existing keys from the main keyring. If such usage of apt-key is desired, the additional installation of the GNU Privacy Guard suite (packaged in gnupg) is required.
apt-key(8) will last be available in Debian 11 and Ubuntu 22.04.
使用如下命令

cd /etc/apt/trusted.gpg.d/
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor >docker.gpg
echo "deb [arch= $( dpkg --print-architecture) ] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu " $( . /etc/os-release && echo " $VERSION_CODENAME " ) " stable" > /etc/apt/sources.list.d/docker.list
列出Docker版本
Centos
1
yum list docker-ce --showduplicates | sort -r
CentOS8 默认使用 podman 代替 docker ，所以需要 containerd.io
安装containerd.io
1
yum -y install https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
Ubuntu
1
sudo apt-cache madison docker-ce| awk '{print $3}'
安装指定版本
Centos

2
yum install docker-ce-<VERSION_STRING>
yum install docker-ce-19.03.15
Ubuntu

2
sudo apt -y install docker-ce= <VERSION_STRING>
sudo apt -y install docker-ce= 5:19.03.15~3-0~ubuntu-focal
修改加速器，添加私有仓库，修改docker默认存储位置

systemctl start docker
systemctl enable docker
为了避免每次命令都输入sudo，可以设置用户权限
1
sudo usermod -a -G docker $USER

yum makecache
1
yum install docker-ce-19.03.9-3.el7
使用之前的数据目录，指定之前的储存目录，我们之前Docker的储存目录是 /data/docker
修改docker默认存储位置，配置镜像加速器，添加私有仓库地址
1
systemctl enable --now docker
以前Docker版本为1.13.1,，在对其版本升级到18.06.1之后，启动旧版本创建的容器时遇到这个错误：
查资料得知：因为「当您从不兼容的版本升级docker并且升级后无法启动docker容器时会出现这种情况」，解决办法如下：
1
2
grep -rl 'docker-runc' /data/docker/containers/ | xargs sed -i 's/docker-runc/runc/g'
systemctl restart docker
/data/docker/containers/为docker存储目录
由于某些项目需要用到中文字体
Dockerfile中添加
1
COPY simsun.ttc /usr/share/fonts/simsun.ttc
执行以下命令查看系统中的中文字体
