使用基础的docker指令来创建镜像，实现项目的发布

dockerfile去创建镜像

docker-compose编排容器

docker pull nginx

使用docker部署project-exam-system（项目）

1.背景，在一台主机之内，实现容器的编排，发布考试系统

2.环境准备

1.docker

1.vim /etc/docker/daemon.json

2.docker-compos

3.普通的部署

1.镜像

1.前端：nginx服务

1.拉取nginx：latest镜像

2.测试

3.上传前端项目dist

4.创建启动容器

docker run -itd -p80:80 -v /root/project_exam_system/web/dist/:/usr/share/nginx/html nginx:latest

2.后端的业务jdk17 springboot优点不用单独部署tomcat，已经在springboot中内置tomcat数据持久化业务

                        ①准备拉去基础centos镜像
                        [root@docker-01 project_exam_system]# docker pull centos

2.docker run -it centos:latest /bin/bash

3.ctrl p+q

4.jdk17版本的文件
5.项目资源 .war

6.将服务器上的java的资源文件上传到容器

1.docker cp jdk... 60:/

2.docker cp Pro... 60:/

3.docker cp app... 60:/

7.对已经传到容器的文件进行部署 docker attach 60

8.tar -zxvf jdk-17_linux-x64_bin.tar.gz -C /usr/local/jdk/ --strip-components=1

9.修改appllcation.properties 文件

1.spring.datesource.url=jdbc:msyql://你的主机的ip:3306/project exam system

2./usr/local/jdk/bin/java -jar Project_ExamSystem-V1.0.0.war

3.Ctrl p q退出

10.根据容器创建镜像 docker commit 60 java：v0

11.docker images 且docker stop 60

12.移除原有的容器 docker rm 60

13.根据新的镜像，创建容器 docker run -itd - p8080:8080 java:v0

14.docker ps 查看容器的进程 docker ps

15.docker attach 8c

16./usr/local/jdk/bin/java -jar Project_ExamSystem-V1.0.0.war

                3.数据持久化业务 mysql5.7.44

(1）拉取MySQL镜像

（2）创建容器并映射端口

                        （3）向容器中上传文件

                        （4）将mysql文件上传

（5）将sql文件上传到mysql容器中

                        （6）使用exec指令访问数据库管理界面

实操：

部署docker

首先部署docker的环境

然后拉取nginx镜像

部署nginx

[root@docker2 ~]# docker pull nginx
[root@docker2 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest 5ef79149e0ec 2 weeks ago 188MB
[root@docker2 ~]# docker run -itd -p80:80 nginx:latest
660f216daec4a1985b86e057396d0b7bec89e22a4fb72bcebe3836f7e2380004
[root@docker2 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
660f216daec4 nginx:latest "/docker-entrypoint.…" 20 seconds ago Up 19 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp peaceful_clarke
[root@docker2 ~]# curl localhost

在容器启动之后，nginx服务就自动发布了

查看nginx容器的资源文件

[root@docker2 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
660f216daec4 nginx:latest "/docker-entrypoint.…" 2 minutes ago Up 2 minutes 0.0.0.0:80->80/tcp, :::80->80/tcp peaceful_clarke
[root@docker2 ~]# docker exec -it 660 ls /usr/share/nginx/html
50x.html index.html
创建一个目录，不单独放置前端的资料，将后端的所有的资料也都放在这里

[root@docker2 ~]# mkdir project_exam_system
[root@docker2 ~]# cd project_exam_system/
[root@docker2 project_exam_system]# mkdir web
上传dist目录scp -r 主机文件地址 root@192.168.2.82:~/project_exam_system/web/

[root@docker2 project_exam_system]# ls web/
dist
[root@docker2 project_exam_system]# ls web/dist/
assets favicon.ico index.html
再创建容器，不止映射端口，还挂载目录

[root@docker2 project_exam_system]# docker stop 660
660
[root@docker2 project_exam_system]# docker rm 660
660
[root@docker2 project_exam_system]# docker run -itd -p80:80 -v /root/project_exam_system/web/dist/:/usr/share/nginx/html nginx:latest
0a98fa10f0d24ea0ef16354b81aa5d65148b774f5e57d4c1d45eca3d6c1c15ab

[root@docker2 project_exam_system]# docker exec -it 0a ls /usr/share/nginx/htmlassets favicon.ico index.html
[root@docker2 project_exam_system]# docker pull centos

部署java

scp -r "D:\企业\第八周\jdk-17_linux-x64_bin.tar.gz" root@192.168.2.82:~

把所需要的文件都上传

[root@docker2 project_exam_system]# ls ~
anaconda-ks.cfg jdk-17_linux-x64_bin.tar.gz
application.properties project_exam_system
docker.sh Project_ExamSystem-V1.0.0.war
[root@docker2 ~]# docker cp jdk-17_linux-x64_bin.tar.gz 60:/
Successfully copied 183MB to 60:/
[root@docker2 ~]# docker cp application.properties 60:/
Successfully copied 4.1kB to 60:/
[root@docker2 ~]# docker cp Project_ExamSystem-V1.0.0.war 60:/
Successfully copied 41MB to 60:/
[root@docker2 ~]# ls
anaconda-ks.cfg jdk-17_linux-x64_bin.tar.gz
application.properties project_exam_system
docker.sh Project_ExamSystem-V1.0.0.war

进入容器

[root@docker2 ~]# docker attach 60
[root@601ec11a7696 /]# mkdir /usr/local/jdk
[root@601ec11a7696 /]# tar -zxvf jdk-17_linux-x64_bin.tar.gz -C /usr/local/jdk/ --strip-components=1

修改配置文件

[root@601ec11a7696 /]# vi application.properties

spring.datesource.url=jdbc:msyql://你的主机的ip:3306/project exam system

启动服务

[root@601ec11a7696 /]# /usr/local/jdk/bin/java -jar Project_ExamSystem-V1.0.0.war

访问一下，说明服务正常启动了

[root@docker2 ~]# curl 172.17.0.3:8080
{"code":20002,"msg":"账号不存在或密码错误"}[root@docker2 ~]# 正常的，只是没有账号密码

创建一个新的镜像

[root@docker2 ~]# docker commit 601 java:v0

mysql容器制作：

106 mkdir mysql
107 ls project_exam_system
108 cp project_exam_system.sql project_exam_system/
109 mv project_exam_system.sql project_exam_system/mysql
110 ls project_exam_system/
111 cd project_exam_system/
112 head mysql/project_exam_system.sql
113 docker ps
114 cd
115 docker cp project_exam_system/mysql/project_exam_system.sql 40:/
116 docker exec -it 40 mysql -uroot -proot

将sql上传到mysql容器中

mysql -uroot -proot < project_exam_system.sql

[root@docker2 ~]# docker exec -it 40 mysql -uroot -proot

docker compose java服务的，手撕了一个镜像

优化java服务
