配置宿主机网卡转发
## 若未配置,需要执行如下
[root@test:~]$ cat <<EOF > /etc/sysctl.d/docker.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward=1
EOF
[root@test:~]$ sysctl -p /etc/sysctl.d/docker.conf
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: 没有那个文件或目录
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: 没有那个文件或目录
net.ipv4.ip_forward = 1
# 由于在网卡配置了IPV6INIT=no,把ipv6关闭了,所以没有bridge-nf-call-ip6tables 那两个文件。
使用yum安装并配置docker
添加阿里源
# 下载阿里源 repo 文件
[root@test:~]$ curl -o /etc/yum.repos.d/Centos-7.repo http://mirrors.aliyun.com/repo/Centos-7.repo

安装
[root@test:~]$ yum clean all && yum makecache
# yum 安装
[root@test:~]$ yum install docker-ce-20.10.6 -y
# 查看源中可用版本
[root@test:~]$ yum list docker-ce --showduplicates | sort -r
# 配置镜像加速源
[root@test:~]$ vim /etc/docker/daemon.json
{
"registry-mirrors" : [
"https://docker.mirrors.ustc.edu.cn"
]
}
# 设置开机自动启动
[root@test:~]$ systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@test:~]$ systemctl daemon-reload
# 启动 docker
[root@test:~]$ systemctl start docker
