docker最新安裝、完全卸載、常用命令及製作並推送鏡像

Docker:是一個開源的引擎，可以輕鬆的爲任何應用創建一個輕量級的、可移植的、自給自足的容器。開發者在筆記本上編譯測試通過的容器可以批量地在生產環境中部署，包括VMs（虛擬機）、bare metal、OpenStack 集羣和其他的基礎應用平臺。

完全卸載：

sudo yum list installed|grep docker
sudo yum remove containerd.io.x86_64 docker-ce.x86_64 docker-ce-cli.x86_64 
sudo rm /etc/yum.repos.d/docker*.repo
sudo rm -rf /etc/systemd/system/docker.service.d
sudo rm -rf /var/lib/docker
sudo rm -rf /var/run/docker
sudo rm -rf /run/docker
sudo rm -rf /etc/docker

最新安裝：

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo yum makecache fast
sudo yum -y install docker-ce
sudo systemctl start docker
sudo systemctl enable docker
vim /etc/docker/daemon.json

}

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
systemctl daemon-reload
systemctl restart docker
sudo docker pull centos:7

常用命令：

sudo docker search centos  --filter "is-official=true" # 顯示官方
sudo docker search centos--stars=3 # 過濾熱度
sudo docker images
sudo docker rmi image id/tag 

啓動docker：systemctl start docker
停止docker：systemctl stop docker
重啓docker：systemctl restart docker
查看docker狀態：systemctl status docker


sudo docker run --name mydocker -it centos:7 /bin/bash
sudo docker stop

sudo docker ps
sudo docker ps -a
sudo docker rm container id
sudo docker rm -f container id
sudo docker attach [container id] #exit之後容器也退出運行了
sudo docker exec -it [container id] /bin/sh #exit之後容器還在運行中
sudo yum -y install docker # 安裝docker
sudo docker pull centos:7 # 拉取centos 7版本的鏡像到本地
touch dockerfile # 編輯dockerfile
sudo docker build -t test1:v1.0 #構建鏡像
sudo docker run -it --rm -p 8080:8080 --privileged=true -v /home/260254/docker/testcutimg-master:/cutimages:rw --name testci test1
