项目环境搭建【Docker+k8s】四 || 部署Docker环境

目录

• 1、安装docker
• 2、docker配置，bip网段与宿主机配置一致
• 3、启动docker

1、安装docker

• 方法一

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
#失败重新安装，先删除rm -f /etc/yum.repos.d/local.rep，docker-ce.repo，在重新安装

• 方法二

yum install -y yum-utils device-mapper-persistent-data lvm2 
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 
yum update -y && yum install -y docker-ce

2、docker配置，bip网段与宿主机配置一致

mkdir -p  /data/docker
mkdir /etc/docker
vi /etc/docker/daemon.json
{
  "data-root": "/data/docker",
  "storage-driver": "overlay2",
  "insecure-registries": ["registry.access.redhat.com","quay.io","harbor.yn.com"],
  "registry-mirrors": ["https://qc20rc43.mirror.aliyuncs.com"],
  "bip": "172.7.100.1/24",
  "exec-opts": ["native.cgroupdriver=systemd"],
  "live-restore": true,
  "log-driver": "json-file", 
  "log-opts": { "max-size": "100m" }
}

3、启动docker

systemctl daemon-reload
systemctl start docker
systemctl enable docker
