0，安装docker rm -rf /etc/yum.repos.d/*.repo wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo sed -i '/aliyuncs/d' /etc/yum.repos.d/CentOS-Base.repo sed -i '/aliyuncs/d' /etc/yum.repos.d/epel.repo cat /etc/redhat-release sed -i 's/$releasever/7.6.1810/g' /etc/yum.repos.d/CentOS-Base.repo yum install docker # yum安装docker systemctl start docker # 启动docker服务 systemctl enable docker # 添加开机启动
查询Docker状态：docker info
1，查看所有docker镜像 docker images
2，拉取docker镜像 docker pull centos
3，查询docker镜像 docekr search centos
4，查看"正在运行的"docker容器 docker ps
5，创建镜像容器，启动并进入 docker run -t -i centos:latest /bin/bash
6，提交现成镜像 docker commit -m "Added json gem" -a "Docker Newbee" f1efdad2a1aa luyanjie/test:v1
7，创建Dockerfile建造镜像（docker.io/luyanjie/test） cat >> Dockerfile << EOF FROM ubuntu:latest MAINTAINER Docker Newbee luyanjie@docker.com RUN apt-get update -y EOF docker build -t="luyanjie/test:v2" .
8，精简docker容器：
cat > Dockerfile << EOF
FROM ubuntu:latest
ENV VER 3.0.0
ENV TARBALL http://download.redis.io/releases/redis-$VER.tar.gz
RUN echo "==> Install curl and helper tools..." && \
apt-get update &&
apt-get install -y curl make gcc &&
echo "==> Download, compile, and install..." &&
curl -L $TARBALL | tar zxv &&
cd redis-$VER &&
make &&
make install &&
echo "==> Clean up..." &&
apt-get remove -y --auto-remove curl make gcc &&
apt-get clean &&
rm -rf /var/lib/apt/lists/* /redis-$VER
CMD ["redis-server"]
EOF
docker build -t="luyanjie/test:v3" .
9，限制docker容器资源：
10，上传Docker镜像： docker login # 登陆Docker Hub docekr logout # 登出 docker tag luyanjie/test docker.io/luyanjie/testmmyytetr22 # 打上自己的标签 docker push docker.io/luyanjie/testmmyytetr # 提交到自己的docker hub
11，升级Docker rpm -qa | grep docker yum remove -y docker-client-1.13.1-63.git94f4240.el7.centos.x86_64 yum remove -y docker-common-1.13.1-63.git94f4240.el7.centos.x86_64 yum remove -y docker-1.13.1-63.git94f4240.el7.centos.x86_64 curl -fsSL https://get.docker.com/ | sh systemctl restart docker systemctl enable docker docker -v
12，镜像（原本）导出 docker save -o 镜像名.tar 镜像名ID 13，镜像（原本）导入 docker load -i 镜像名.tar 14，镜像（有备份变更）导出 docker export -o 容器名.tar 容器名ID 15，镜像（有备份变更）导入 docker import 容器名.tar 镜像名称:tag名称
16，简化alpine常用镜像： docker pull smebberson/alpine-nginx docker pull sickp/alpine-redis
17，初次进入容器： 一般Linux：docker run -it 镜像名 /bin/bash 登陆alpine：docker run -it 镜像名 sh
18，重新进入容器： 登陆alpine：docker exec -it CONTAINER_ID sh 一般Linux：docker exec -it CONTAINER_ID /bin/bash
19，指定容器名称： docker run --name bob_the_container -i -t ubuntu /bin/bash
20，指定容器开放端口： docker pull nginx docker run -p 8888:80 --name=nginx -i -t 540a289bab6c
21，目录映射： docker run -p 8888:80 --name=nginx -i -t -v /home/test/nginx/html:/usr/share/nginx/html 540a289bab6c
22，运行中的容器添加端口映射：
docker inspect nginx | grep IPAddress # 获取容器IP地址
iptables -t nat -A DOCKER -p tcp --dport 8002 -j DNAT --to-destination 172.17.0.4:80
23，删除存在端口规则 iptables -t nat -vnL DOCKER --line-number iptables -t nat -D DOCKER 3
docker inspect nginx | grep IPAddress # 获取容器IP地址
