docker最新安装、完全卸载、常用命令及制作并推送镜像

Docker:是一个开源的引擎，可以轻松的为任何应用创建一个轻量级的、可移植的、自给自足的容器。开发者在笔记本上编译测试通过的容器可以批量地在生产环境中部署，包括VMs（虚拟机）、bare metal、OpenStack 集群和其他的基础应用平台。

完全卸载：

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

最新安装：

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" # 显示官方
sudo docker search centos--stars=3 # 过滤热度
sudo docker images
sudo docker rmi image id/tag 

启动docker：systemctl start docker
停止docker：systemctl stop docker
重启docker：systemctl restart docker
查看docker状态：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之后容器也退出运行了
sudo docker exec -it [container id] /bin/sh #exit之后容器还在运行中
sudo yum -y install docker # 安装docker
sudo docker pull centos:7 # 拉取centos 7版本的镜像到本地
touch dockerfile # 编辑dockerfile
sudo docker build -t test1:v1.0 #构建镜像
sudo docker run -it --rm -p 8080:8080 --privileged=true -v /home/260254/docker/testcutimg-master:/cutimages:rw --name testci test1
