阿里云镜像加速
-
登录阿里云找到容器服务
https://cr.console.aliyun.com/?spm=a2c4g.11186623.2.7.5daa7627kOSW0h
-
2.找到镜像加速地址
3.配置使用
sudo mkdir -p /etc/docker
#创建一个目录
sudo tee /etc/docker/daemon.json <<-\'EOF\'
{
"registry-mirrors": ["https://gbdey2h8.mirror.aliyuncs.com"]
}
EOF
#编写配置文件
sudo systemctl daemon-reload
sudo systemctl restart docker
回顾Hello World流程
底层原理
Docker是怎么工作的?
Docker是一个Client - Server结构的系统,Docker的守护进程运行在我们的主机上,通过Socket从客户端访问!
DockerServer接收到Docker-Client的指令,就会执行这个命令!
Docker为什么比VM快
1.Docker有着比虚拟机更少的抽象层。
2.Docker利用的是宿主机的内核,vm需要的是Guest OS
所以说,新建一个容器的时候,docker不需要像虚拟机一样重新加载一个操作系统内核,避免引导。虚拟机时加载Guest OS,分钟级别的,而docker是利用宿主机的操作系统,省略了复杂的过程,秒级的。
之后学习完所有的命令,再回过头来看这段理论,就会很清晰!
Docker的常用命令
帮助命令
docker version #显示docker的版本信息
docker info #显示docker的系统信息,包括镜像和容器的数量
docker 命令 --help #帮助命令

dockers rml 删除镜像
[root@hsStudy ~]# docker rmi -f 镜像id #删除指定的镜像
[root@hsStudy ~]# docker rmi -f 镜像id 容器id 容器id #删除多个指定的镜像
[root@hsStudy ~]# docker rmi -f $(docker images -aq) # 删除全部镜像
容器命令
说明:我们有了镜像才可以创建容器,linux,下载一个CentOS镜像来测试学习
docker pull centos
新建容器并启动
docker run [可选参数] image
#参数说明
--name="Name" 容器名字 tomcat01 tomcat02 用来区分容器
-d 以后台方式运行,ja nohub
-it 使用交互模式运行,进入容器查看内容
-p 指定容器的端口 -p 8080:8080
-p ip主机端:容器端口
-p 主机端:容器端口 主机端口映射到容器端口 (常用)
-p 容器端口
容器端口
-P 随机指定端口
#测试,启动并进入容器
[root@hsStudy ~]# docker run -it centos /bin/bash
[root@9f8cb921299a /]#
[root@9f8cb921299a /]# ls #查看容器内的centos,基础命令很多都是不完善的
bin etc lib lost+found mnt proc run srv tmp var

[root@9f8cb921299a /]# exit
exit
[root@hsStudy /]# ls

boot etc lib lost+found mnt proc run srv tmp var
列出所有运行中的容器
# docker ps 命令
#列出当前正在运行的容器
-a #列出当前正在运行的容器+带出历史运行过的容器
-n=? #显示最近创建的容器
-q #只显示容器的编号
[root@hsStudy ~]# docker ps

删除容器
docker rm 容器id #删除指定的容器,不能删除正在运行的容器,如果要强制删除,rm -f
docker rm -f $(docker ps -aq) #删除所有的容器
docker ps -a -q|xargs docker rm #删除若有容器(使用linux管道命令)
启动和停止容器的操作
docker start 容器id #启动容器
docker restart 容器id #重起容器
docker stop 容器id #停止当前正在运行的容器
docker kill 容器id #强制停止当前容器
常用其他命令
后台启动容器
# 命令 docker run -d 镜像名
[root@hsStudy ~]# docker run -d centos
# docker ps , 发现centos停止了
# 常见的坑,docker 容器使用后台运行,就必须要有一个前台进程,docker发现没有应用,就会自动停止
#nagix,容器启动后,发现自己没有提供服务,就会立即停止,没有程序了
查看日志命令
docker logs -f -t --tail 容器 没有日志
# 自己编写一段shell脚本
[root@hsStudy /]# docker run -d centos /bin/sh -c "while true;do echo hansuo;sleep;done"
[root@hsStudy /]# docker ps
CONTAINER ID IMAGE
4466628037e0 centos
#显示日志
-tf #显示日志
--tail number # 要显示的日志条数
docker logs -f -t --tail 10 4466628037e0
查看容器中的进程信息
# 命令 docker top 容器id
[root@hsStudy /]# docker top 4466628037e0

端口暴露的概念
思考问题:我们每次改动nginx配置文件,都需要进去容器内部,十分麻烦,我要是可以再容器外部提供一个映射路径,达到在容器修改文件名,容器就可以自动修改了? -v 数据卷技术
可以使用浏览器看服务是否开启。
你的虚拟机IP地址加上3344即可访问
作业:docker 来装以个tomcat
#官方的使用
docker run -it --rm tomcat:9.0
#我们之前的启动都是后台,停止了容器之后,容器还可以查到。docker run -it --rm 一般用来测试,用完及删
# 下载再启动
docker pull tomcat
#启动运行
docker run -d -p 3355:8080 --name tomcat01 tomcat
#测试访问没有问题
#进入容器
[root@hsStudy ~]# docker exec -it tomcat01 /bin/bash
#发现问题 1.linux命令少了.2.没有webapps。阿里云镜像的原因,默认是最小的镜像,所有的不必要的都剔除掉了
#保证最小可运行环境
#进入容器,将文件拷贝下,即可出现tomcat成功启动的封面了

思考问题:我们以后要部署项目,如果每次都要进入容器是不是十分麻烦?我要是可以再容器外部提供一个映射路径,webapps我们再外部放置项目,就自动同步到内部就好了!
