查看DockerHub，拉取Nginx镜像，创建并运行容器
搜索Nginx镜像：在 www.hub.docker.com 网站进行查询
拉取镜像：
docker pull nginx查看本地镜像列表：
docker images将拉取到本地的镜像进行打包，保存为文件
[root@server02 ~]# docker save --help
//查询docker save的命令的用法
Usage: docker save [OPTIONS] IMAGE [IMAGE...]
Save one or more images to a tar archive (streamed to STDOUT by default)
Aliases:
docker image save, docker save
//由此可知 该命令有 -o 表示设置 镜像的存储文件nginx.tar
Options:
-o, --output string Write to a file, instead of STDOUT
[root@server02 ~]# ^C
[root@server02 ~]# docker save -o nginx.tar nginx

提取本地镜像文件
[root@server02 ~]# docker load --help
Usage: docker load [OPTIONS]
Load an image from a tar archive or STDIN
Aliases:
docker image load, docker load
Options:
-i, --input string Read from tar archive file, instead of STDIN
-q 表示是否显示提去细节
-q, --quiet Suppress the load output
[root@server02 ~]#
提去本地文件，只需要指定文件名即可

数据卷
案例：利用Nginx容器部署静态资源
- 进入容器内部：
[root@server02 ~]# docker exec -it nginx bash- 通过在DockerHub中查找可知Nginx的静态资源存放在 ‘/usr/share/nginx/html/index.html’文件中，由于容器没有提供非必要的依赖，所以没有修改文件的命令（vim）无法修改，由此引入数据卷。

Mounts部分为挂载信息，在创建容器时就自动创建挂载用来存储数据库中的数据。使用的是匿名卷，
可以发现，其中有几个关键属性：
-
Name：数据卷名称。由于定义容器未设置容器名，这里的就是匿名卷自动生成的名字，一串hash值。
-
Source：宿主机目录
-
Destination : 容器内的目录
上述配置是将容器内的/var/lib/mysql这个目录，与数据卷bb415299e39a1c7425861ee4add16668301e28c419cde8e35f5c436a69f228a4挂载。于是在宿主机中就有了/var/lib/docker/volumes/bb415299e39a1c7425861ee4add16668301e28c419cde8e35f5c436a69f228a4/_data这个目录。这就是匿名数据卷对应的目录，其使用方式与普通数据卷没有差别。
可以发现，数据卷的目录结构较深，如果我们去操作数据卷目录会不太方便。在很多情况下，我们会直接将容器目录与宿主机指定目录挂载。挂载语法与数据卷类似：
# 挂载本地目录
-v 本地目录:容器内目录
# 挂载本地文件

例如，要基于Ubuntu镜像来构建一个Java应用，其Dockerfile内容如下：
# 指定基础镜像
FROM ubuntu:16.04
# 配置环境变量，JDK的安装目录、容器内时区
ENV JAVA_DIR=/usr/local
ENV TZ=Asia/Shanghai
# 拷贝jdk和java项目的包
COPY ./jdk8.tar.gz $JAVA_DIR/
COPY ./docker-demo.jar /tmp/app.jar
# 设定时区
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
# 安装JDK
RUN cd $JAVA_DIR \
&& tar -xf ./jdk8.tar.gz \
&& mv ./jdk1.8.0_144 ./java8
# 配置环境变量
ENV JAVA_HOME=$JAVA_DIR/java8
ENV PATH=$PATH:$JAVA_HOME/bin
# 指定项目监听的端口
EXPOSE 8080
# 入口，java项目的启动命令
ENTRYPOINT ["java", "-jar", "/app.jar"]就有人提供了基础的系统加JDK环境，我们在此基础上制作java镜像，就可以省去JDK的配置了：
# 基础镜像
FROM openjdk:11.0-jre-buster
# 设定时区
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
# 拷贝jar包
COPY docker-demo.jar /app.jar
# 入口
ENTRYPOINT ["java", "-jar", "/app.jar"]由于要下载JDK到本地所以先上传JDK到本地镜像

好了，我们已经熟悉了Docker的基本用法，接下来可以尝试部署项目了。
在课前资料中已经提供了一个黑马商城项目给大家，如图：
项目说明：
-
hmall：商城的后端代码
-
hmall-portal：商城用户端的前端代码
-
hmall-admin：商城管理端的前端代码
部署的容器及端口说明：
| 项目 | 容器名 | 端口 | 备注 |
|---|---|---|---|
| hmall | hmall | 8080 | 黑马商城后端API入口 |
| hmall-portal | nginx | 18080 | 黑马商城用户端入口 |
| hmall-admin | 18081 | 黑马商城管理端入口 | |
| mysql | mysql | 3306 | 数据库 |
在正式部署前，我们先删除之前的nginx、dd两个容器：
docker rm -f nginx dd
mysql容器中已经准备好了商城的数据，所以就不再删除了。
3.1.部署Java项目
hmall项目是一个maven聚合项目，使用IDEA打开hmall项目，查看项目结构如图：
我们要部署的就是其中的hm-service，其中的配置文件采用了多环境的方式：
其中的application-dev.yaml是部署到开发环境的配置，application-local.yaml是本地运行时的配置。
查看application.yaml，你会发现其中的JDBC地址并未写死，而是读取变量：
这两个变量在application-dev.yaml和application-local.yaml中并不相同：
在dev开发环境（也就是Docker部署时）采用了mysql作为地址，刚好是我们的mysql容器名，只要两者在一个网络，就一定能互相访问。
我们将项目打包：
结果：
将hm-service目录下的Dockerfile和hm-service/target目录下的hm-service.jar一起上传到虚拟机的root目录：
部署项目：
# 1.构建项目镜像，不指定tag，则默认为latest docker build -t hmall . # 2.查看镜像 docker images # 结果 REPOSITORY TAG IMAGE ID CREATED SIZE hmall latest 0bb07b2c34b9 43 seconds ago 362MB docker-demo 1.0 49743484da68 24 hours ago 327MB nginx latest 605c77e624dd 16 months ago 141MB mysql latest 3218b38490ce 17 months ago 516MB # 3.创建并运行容器，并通过--network将其加入hmall网络，这样才能通过容器名访问mysql docker run -d --name hmall --network hmall -p 8080:8080 hmall
测试，通过浏览器访问：http://你的虚拟机地址:8080/search/list

[root@server02 ~]#
创建新Nginx容器并进行挂载和加入网络
修改配置文件（即后端容器的名字使前端可以访问后端）：
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/json;
sendfile on;
keepalive_timeout 65;
server {
listen 18080;
# 指定前端项目所在的位置
location / {
root /usr/share/nginx/html/hmall-portal;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location /api {
rewrite /api/(.*) /$1 break;
proxy_pass http://hm:8080;
}
}
server {
listen 18081;
# 指定前端项目所在的位置
location / {
root /usr/share/nginx/html/hmall-admin;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location /api {
rewrite /api/(.*) /$1 break;
proxy_pass http://hm:8080;
}
}
}然后创建nginx容器并完成两个挂载：
-
把
/root/nginx/nginx.conf挂载到/etc/nginx/nginx.conf -
把
/root/nginx/html挂载到/usr/share/nginx/html
由于需要让nginx同时代理hmall-portal和hmall-admin两套前端资源，因此我们需要暴露两个端口：
-
18080：对应hmall-portal
-
18081：对应hmall-admin
命令如下：
docker run -d \
--name nginx \
-p 18080:18080 \
-p 18081:18081 \
-v /root/nginx/html:/usr/share/nginx/html \
-v /root/nginx/nginx.conf:/etc/nginx/nginx.conf \
--network wmmczk\
