安装
#卸载Docker
# 卸载依赖
yum remove docker-ce docker-ce-cli containerd.io
# 删除资源
rm -rf /var/lib/docker # docker 的默认工作路径
# 1.卸载旧的版本
$ sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
#2.# 安装基本的安装包
$ sudo yum install -y yum-utils
#3.设置镜像仓库
$ sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo # 默认是国外的
# 换成下面的
$ sudo yum-config-manager \
--add-repo \
https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # 阿里云镜
# 更像软件包索引
yum makecache fast
# 4.安装docker引擎
yum install docker-ce docker-ce-cli containerd.io # docker-ce 社区版 ee 企业
#5. 启动Docker
systemctl start docker # 代表启动成功
#查看是否安装成功
#6.hello,world 本地没有，从仓库拉取
docker run hello-world
#7.查看下载的镜像
docker images

#before：这个是根据时间来进行过滤，其中before的value表示某个镜像构建时间之前的镜像列表
#since：跟before正好相反，表示的是在某个镜像构建之后构建的镜像
#reference：这个是添加正则进行匹配

#进入容器
[root@iZ2ze9fp041k3gtah0ztnmZ ~]# docker exec -it nginx01 /bin/bash
root@d220177f71af:/# cd /etc/nginx
#查看文件
root@d220177f71af:/etc/nginx# ls
conf.d fastcgi_params mime.types modules nginx.conf scgi_params uwsgi_params
每次需要修改nginx配置文件都要进入容器内部修改，非常麻烦
部署tomcat
#下载tomcat
docker pull tomcat:9.0
#运行
[root@iZ2ze9fp041k3gtah0ztnmZ ~]# docker run -d -p 3355:8080 --name tomcat01 tomcat
