1.配置Docker的加速器及数据目录

[root@node1 ~]# mkdir /etc/docker
[root@node1 ~]# mkdir /data/docker -p

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "graph": "/data/docker",
  "storage-driver": "overlay2",
  "insecure-registries": ["registry.access.redhat.com","quay.io"],
  "registry-mirrors": ["https://meme61ip.mirror.aliyuncs.com"],
  "bip": "172.7.99.1/24",
  "exec-opts": ["native.cgroupdriver=systemd"],
  "live-restore": true
}
EOF

# 相关解释
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "graph": "/data/docker",                                             # docker工作目录
  "storage-driver": "overlay2",                                       # 存储驱动
  "insecure-registries": ["registry.access.redhat.com","quay.io"],  # 不安全的仓库
  "registry-mirrors": ["https://meme61ip.mirror.aliyuncs.com"],      # 加速镜像
  "bip": "172.7.99.1/24",                                           # docker的网络,尽量要与宿主机有个对照关系
  "exec-opts": ["native.cgroupdriver=systemd"],                     # cgroup的类型
  "live-restore": true                                              # 让docker容器不依懒docker引擎的死与活
}
EOF

2.启动Docker

[root@node1 ~]# systemctl enable docker.service
[root@node1 ~]# systemctl start docker.service

3.核查docker配置及启动情况

[root@node1 ~]# docker info
