Ubuntu 16.04下Docker部署SpringBoot、

本文以开源项目SpringBlade和Saber为例。

1、创建自定义网络
目的是将用到的服务都放到同一个网络段，以方便互相通信。
docker network create --subnet 172.19.0.0/16 mynetwork

2、Docker安装MySQL、Redis、Nginx
（1）安装MySQL
docker pull mysql:5.7.30
cd ~
mkdir docker/mysql/{conf,logs,data} -p
cd docker/mysql
docker run --name mysql_blade --network=mynetwork --ip=172.19.0.6 -p 3307:3306 -v PWD/logs:/var/log/mysql -v PWD/data:/data:rw -v $PWD/conf/redis.conf:/etc/redis/redis.conf:ro --privileged=true --name redis-6389 -d redis redis-server /etc/redis/redis.conf
（3）安装Nginx
将Saber发布到Nginx中要用到
docker pull nginx
2、Docker打包SpringBlade

3、Docker打包并发布Saber
（1）编写nginx.conf
cd Saber
touch nginx.conf，写入以下内容：
//nginx.conf开始
user root;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
worker_connections 1024;
}

http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /var/log/nginx/access.log  main;

sendfile        on;
#tcp_nopush     on;

keepalive_timeout  65;

#gzip  on;

#include /etc/nginx/conf.d/*.conf;

upstream gateway {
             server 172.19.0.7:9001;
         }


server {
  listen       1889;
  server_name  web;
  root         /usr/share/nginx/html;

  location / {
       try_files $uri $uri/ /index.html;

  }

  location ^~/api {
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_buffering off;
       rewrite ^/api/(.*)$ /$1 break;
       proxy_pass http://gateway;
  }
}

}
//nginx.conf结束
（2）编写Dockerfile
编写dockerfile并将其放到与dist同一目录：
FROM nginx
VOLUME /tmp
ENV LANG en_US.UTF-8
ADD ./dist/ /usr/share/nginx/html/
COPY./nginx.conf /etc/nginx/
EXPOSE 1889
EXPOSE 443
（3）打包并发布
cd ~
mkdir docker/saber/conf -p
cd docker/saber
cp ~/Saber/nginx.conf conf
yarn run build
docker build -t saber:1.0 .（注意最后的.）
docker run -itd --name saber --network=mynetwork --ip=172.19.0.8 -p 1889:1889 -v $PWD/conf:/mnt/ saber:1.0

4、Docker打包并发布SpringBlade
（1）pom.xml配置
/
<docker.repostory>10.10.0.127:10080</docker.repostory>
<docker.registry.name>blade</docker.registry.name>
<docker.image.tag>0.0.1</docker.image.tag>
<docker.maven.plugin.version>1.4.10</docker.maven.plugin.version>

<build>
<finalName>SpringBlade</finalName>
<resources>
<resource>
<directory>src/main/resources</directory>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>*/.xml</include>
</includes>
</resource>
</resources>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>{project.build.finalName}</finalName>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>{project.basedir}</contextDirectory>

<useMavenSettingsForAuth>true</useMavenSettingsForAuth>
<repository>{docker.registry.name}/{docker.image.tag}</tag>
<buildArgs>
<JAR_FILE>target/{java.version}</source>
<target>${java.version}</target>
<encoding>UTF-8</encoding>
<compilerArgs>
<arg>-parameters</arg>
</compilerArgs>
</configuration>
</plugin>
</plugins>
</build>

（2）yml配置
redis及mysql都要与前面的创建容器时的配置相同：

（2）创建私有仓库（利用Harbor）
在harbor管理界面创建项目blade，下面上传镜像的时候要加入项目路径。
（3）打包
mvn clean install dockerfile:build -Dmaven.test.skip=true
（4）上传到私有仓库
两种方式：
mvn dockerfile:push
或者docker push 10.10.0.127:10080/blade/springblade:0.0.1
然后在Harbor管理后台就可以看到镜像了。
要pull下来的话：
docker pull 10.10.0.127:10080/blade/springblade:0.0.1
（5）发布
cd ~
mkdir docker/blade/app -p
cd docker/blade
docker run -itd --name blade --network=mynetwork --ip=172.19.0.7 -p 9001:9001 -v $PWD/app:/mnt/ 10.10.0.127:10080/blade/springblade:0.0.1
