Docker & Compose安装以及入门

Docker 安装

脚本安装

• 自定义脚本

  wget https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm
  yes | yum localinstall docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm
  systemctl start docker
  # add aliyun accelarater
  touch /etc/docker/daemon.json
  cat>>/etc/docker/daemon.json<<EOF 
  {
      "insecure-registries" : ["0.0.0.0/0"],
      "registry-mirrors": ["https://4wmjwi37.mirror.aliyuncs.com"],
      "log-driver": "json-file",
      "log-opts": {
          "max-size": "10m",
          "max-file": "3"
      }
  }
  EOF
  systemctl daemon-reload
  systemctl restart docker
  docker info
  

• docker社区

  curl -sSL https://get.docker.com | sh
  docker -v
  

• 阿里云脚本

  curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
  docker -v
  

• daocloud脚本

  curl -sSL https://get.daocloud.io/docker | sh
  docker -v
  

配置加速器

• 阿里云

  sudo mkdir -p /etc/docker
  sudo tee /etc/docker/daemon.json <<-'EOF'
  {
    "registry-mirrors": ["https://dist7hw1.mirror.aliyuncs.com"]
  }
  EOF
  sudo systemctl daemon-reload
  sudo systemctl restart docker
  docker info
  

• DaoCloud

  curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://ced808ab.m.daocloud.io
  
  sudo systemctl restart docker
  
  docker info
  
  

卸载 Docker

• 卸载脚本

  #sudo apt-get remove docker docker-engine docker.io
  yum remove docker 
  				  docker-client 
  				  docker-client-latest 
  				  docker-common 
  				  docker-latest 
  				  docker-latest-logrotate 
  				  docker-logrotate 
  				  docker-selinux 
  				  docker-engine-selinux 
  				  docker-engine
  
  rpm -qa | grep docker | xargs yum remove
  
  rm -rf /etc/systemd/system/docker.service.d
  
  rm -rf /var/lib/docker
  
  rm -rf /var/run/docker
  
  

Docker Compose安装

二进制包安装（推荐）

• 官网
  https://github.com/docker/compose/releases

• 安装脚本

  sudo curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
  sudo chmod +x /usr/local/bin/docker-compose
  sudo docker-compose -v
  

• 卸载脚本

  sudo rm -rf /usr/local/bin/docker-compose
  

PIP 安装

#pip -V
#安装 python-pip
yum -y install epel-release
yum -y install python-pip
pip install --upgrade pip
pip -V
sudo pip install -U docker-compose
docker-compose -version
