SET UP THE REPOSITORY

  sudo yum install -y  yum-utils device-mapper-persistent-data lvm2  ?  sudo yum-config-manager --add-repo \   https://download.docker.com/linux/centos/docker-ce.repo  ?

Optional

  sudo yum-config-manager --enable docker-ce-edge  sudo yum-config-manager --enable docker-ce-test  #可以关闭  sudo yum-config-manager --disable docker-ce-edge

INSTALL DOCKER CE

1、common install

  sudo yum install -y docker-ce

2、to install specific version

  yum list docker-ce --showduplicates | sort -r  ?  #docker-ce.x86_64            18.09.0.ce-1.el7.centos           docker-ce-stablebash  ?  sudo yum install docker-ce-<VERSION STRING>

3、start and verify

  sudo systemctl start docker  sudo docker run hello-world

Install using the convenience script

  $ curl -fsSL https://get.docker.com -o get-docker.sh  $ sudo sh get-docker.sh  ?  <output truncated>  ?   sudo usermod -aG docker your-user

Uninstall Docker CE

  sudo yum remove docker-ce  sudo rm -rf /var/lib/docker

Test Docker version

  docker --version  sudo docker info

Test Docker installation

  sudo docker run hello-world  sudo docker image ls  sudo docker container ls --all

Recap and cheat sheet

  ## List Docker CLI commands  docker  docker container --help  ?  ## Display Docker version and info  docker --version  docker version  docker info  ?  ## Execute Docker image  docker run hello-world  ?  ## List Docker images  docker image ls  ?  ## List Docker containers (running, all, all in quiet mode)  docker container ls  docker container ls --all  docker container ls -aq

客户端配置

1、证书方式

  sudo mkdir -p /etc/docker/certs.d/192.192.49.87  sudo cp /var/docker-data/certs/domain.crt /etc/docker/certs.d/192.192.49.87/ca.crt  ?  #可能需要OS级信任  sudo cp /etc/dockercerts/domain.crt /etc/pki/ca-trust/source/anchors/192.192.49.87.crt  sudo update-ca-trust  ?

2、http方式

  #或者关闭安全  sudo cat << EOF > /etc/docker/daemon.json  {    "insecure-registries" : ["192.192.49.87"]  }  EOF  ?  sudo systemctl restart docker

docker-compose配置

安装

  sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose  ?  sudo chmod +x /usr/local/bin/docker-compose  ?  sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose  docker-compose --version
