Docker环境构建

• Install required packages
• set up the stable repository
• Install the latest version of Docker CE and containerd

  groupadd -g 1000 admin
  useradd  -u 1000 -g admin admin
  #配置yum源
  wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
  yum makecache
  yum update -y
  yum install -y yum-utils device-mapper-persistent-data lvm2
  yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
  yum install docker-ce docker-ce-cli containerd.io

  配置镜像加速器及私有仓库(可选，此例为阿里云个人账户生成加速地址)

  #配置镜像加速器
  mkdir -p /etc/docker
  tee /etc/docker/daemon.json <<-'EOF'
  {
    "registry-mirrors": ["https://xkl7mn17.mirror.aliyuncs.com","http://f1361db2.m.daocloud.io"],
    "insecure-registries": ["registry.cn-hangzhou.aliyuncs.com"]
  }
  EOF
  

  demo.json配置文件默认没有，需手动创建，官方配置说明https://docs.docker.com/engine/reference/commandline/dockerd/#daemon-configuration-file
  其他镜像加速地址：
  Docker Hub：https://reg-mirror.qiniu.com
  GCR：https://gcr-mirror.qiniu.com
  Quay：https://quay-mirror.qiniu.com
  配置docker账户(可选，此例为阿里云个人账户)
  

  tee /etc/profile.d/docker.sh <<-'EOF'
  export Registry=registry.cn-hangzhou.aliyuncs.com
  docker login --username=--username=luobin.jdq@dtstack.com registry.cn-shanghai.aliyuncs.com --password=z8g2h617... 1>/dev/null 2>&1
  EOF
  source /etc/profile
  

  配置docker数据目录(可选) ``` mkdir -pv /data/docker mv /var/lib/docker /data/docker ln -sv /data/docker /var/lib/docker

systemctl daemon-reload systemctl start docker.service systemctl enable docker.service

chmod a+rw /var/run/docker.sock systemctl stop firewalld.service systemctl disable firewalld.service

### 离线安装docker：

groupadd -g 1000 admin useradd -u 1000 -g admin admin wget xxxx/docker-17.12.0-ce.tgz[自制镜像] tar xzvf docker-17.12.0-ce.tgz cp docker/* /usr/local/bin tee /etc/systemd/system/docker.service <<-‘EOF’ [Service] ExecStart=/usr/local/bin/dockerd EOF

配置docker数据目录

mkdir -pv /data/docker mv /var/lib/docker /data/docker ln -sv /data/docker /var/lib/docker systemctl daemon-reload systemctl start docker.service systemctl enable docker.service

chmod a+rw /var/run/docker.sock

systemctl stop firewalld.service systemctl disable firewalld.service ```
