本文以開源項(xiàng)目SpringBlade和Saber為例。
1、創(chuàng)建自定義網(wǎng)絡(luò)
目的是將用到的服務(wù)都放到同一個(gè)網(wǎng)絡(luò)段，以方便互相通信。
docker network create --subnet 172.19.0.0/16 mynetwork
2、Docker安裝MySQL、Redis、Nginx
（1）安裝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 $PWD/conf/redis.conf:/etc/redis/redis.conf:ro --privileged=true --name redis-6389 -d redis redis-server /etc/redis/redis.conf
（3）安裝Nginx
將Saber發(fā)布到Nginx中要用到
docker pull nginx
2、Docker打包SpringBlade
3、Docker打包并發(fā)布Saber
（1）編寫nginx.conf
cd Saber
touch nginx.conf，寫入以下內(nèi)容：
//nginx.conf開始
user root;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$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結(jié)束
（2）修改env.js文件
baseUrl要與下面的SpringBlade容器的地址和端口匹配：
（3）編寫Dockerfile
編寫dockerfile并將其放到與dist同一目錄：
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
（4）打包并發(fā)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 $PWD/conf:/mnt/ saber:1.0
4、Docker打包并發(fā)布SpringBlade
（1）pom.xml配置
/
<docker.repostory>10.10.0.127:10080</docker.repostory>
<docker.registry.name>blade</docker.registry.name>
<docker.image.tag>0.0.1</docker.image.tag>
<docker.maven.plugin.version>1.4.10</docker.maven.plugin.version>
<build>
<finalName>SpringBlade</finalName>
<resources>
<resource>
<directory>src/main/resources</directory>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>*/.xml</include>
</includes>
</resource>
</resources>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>{project.build.finalName}</finalName>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>{project.basedir}</contextDirectory>
<useMavenSettingsForAuth>true</useMavenSettingsForAuth>
<repository>{docker.registry.name}/
{docker.image.tag}</tag>
<buildArgs>
<JAR_FILE>target/{java.version}</source>
<target>${java.version}</target>
<encoding>UTF-8</encoding>
<compilerArgs>
<arg>-parameters</arg>
</compilerArgs>
</configuration>
</plugin>
</plugins>
</build>
（2）yml配置
redis及mysql都要與前面的創(chuàng)建容器時(shí)的配置相同：
（3）創(chuàng)建私有倉庫（利用Harbor）
在harbor管理界面創(chuàng)建項(xiàng)目blade，下面上傳鏡像的時(shí)候要加入項(xiàng)目路徑。
（4）打包
mvn clean install dockerfile:build -Dmaven.test.skip=true
（5）上傳到私有倉庫
兩種方式：
mvn dockerfile:push
或者docker push 10.10.0.127:10080/blade/springblade:0.0.1
然后在Harbor管理后臺就可以看到鏡像了。
要pull下來的話：
docker pull 10.10.0.127:10080/blade/springblade:0.0.1
（6）發(fā)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
至此，就可以通過localhost:1889來訪問Saber了。
另外，我通過uri來區(qū)分多租戶。例如localhost:1889是管理租戶，localhost:1889/test是名為test的租戶。這樣就避免了在登錄界面填寫租戶id。
