1,docker安装配置

环境 centos7.2

yum install -y yum-utils

yum-config-manager 
--add-repo 
https://download.docker.com/linux/centos/docker-ce.repo

yum-config-manager --enable docker-ce-edge

yum clean all && yum makecache

yum install -y docker-ce.x86_64

  

配置加速器

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://50208f86.m.daocloud.io
systemctl daemon-reload && systemctl start docker


curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://8c593af7.m.daocloud.io
systemctl daemon-reload && systemctl start docker

  

导入导出镜像

docker save images > aa.tar.gz
docker load -qi nginxplus.tar

docker常用操作

4,docker常用命令
镜像操作:
搜索 docker search
获取 docker pull
查看 docker images
删除 docker rmi

镜像导入导出:

docker export id > cenos6.tar
cat centos.tar|docker import - centos6

  


运行镜像:

docker run centos echo "hello word"#在docker容器中运行hello world!
docker run centos yum install ntpdate#在容器中安装ntpdate的程序

  

提交刚修改的容器为镜像:

docker commit 2313132 centos:v1
docker commit -m "My Nginx" fa1529ebdb96 mynginx:v1


容器id

关闭启动删除容器:

docker stop id
docker start id #docker start 5c4a428e7335 
docker rm -f id
docker run --name lannydocker -it centos /bin/bash
docker run --rm --name lannydocker -it centos /bin/bash

  

映射端口:
docker run -d -p 80:80 -p 8022:22 centos:v2


镜像--运行--exit--后台运行--再次进入
方法1,
docker start id
docker attach b83fff0e6cdc
对于nginx可能会进入失败
使用nscenter进去,yum install util-linux –y


方法2,脚本方法重新进容器
docker start id
./in.sh mynginx

其它命令:

容器停止后就自动删除:     docker run --rm centos /bin/echo "One"
杀死所有正在运行的容器:  docker kill $(docker ps -a -q)
删除所有已经停止的容器:  docker rm $(docker ps -a -q)
删除所有未打标签的镜像     docker rmi $(docker images -q -f dangling=true)

进入容器脚本:in.sh

#!/bin/bash

# Use nsenter to access docker

docker_in(){
NAME_ID=$1
PID=$(docker inspect -f "{{ .State.Pid }}" $NAME_ID) 
nsenter -t $PID -m -u -i -n -p
}

docker_in $1
