1、Docker 创建调度中心

docker run -e PARAMS="--spring.datasource.url=jdbc:mysql://xxx:3306/xxl_job?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai --spring.datasource.username=root --spring.datasource.password=xx" -p 8080:8080 -v /tmp:/data/applogs --name xxl-job-admin  -d xuxueli/xxl-job-admin:2.2.0  

2、登陆调度中心

地址：
http://xxxx:8080/xxl-job-admin/  

账号：admin / 123456

3、Docker 部署 sample （默认执行器）

（1）先找到代码，比如上面的是2.2.0，打包sample

（2）编写Dockerfile

FROM openjdk:8-jre-slim
MAINTAINER summer

ENV PARAMS=""

ENV TZ=PRC
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone && mkdir -p /data/applogs/xxl-job/jobhandler

ADD target/*.jar /app.jar

ENTRYPOINT ["sh","-c","java -jar /app.jar $PARAMS"]

（3）Build and Run

[Build]
docker build -t summer/xxljobsample:v1 .


[执行]
docker run -e PARAMS="--xxl.job.admin.addresses=http://xxl-job-admin-host:8080/xxl-job-admin --xxl.job.executor.port=9999" -p 8081:8081 -p 9999:9999 -v /tmp:/data/applogs --name xxl-job-executor-sample --link xxl-job-admin:xxl-job-admin-host -d summer/xxljobsample:v1

4、编写自己的执行器

（1）pom文件中加入

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>

        <!-- https://mvnrepository.com/artifact/com.xuxueli/xxl-job-core -->
        <dependency>
            <groupId>com.xuxueli</groupId>
            <artifactId>xxl-job-core</artifactId>
            <version>2.2.0</version>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>${spring-boot.version}</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>${java.version}</source>
                    <target>${java.version}</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>

（2）编写XxlJobConfig 配置类

@Configuration
@Log4j2
public class XxlJobConfig {

    @Value("${xxl.job.admin.addresses}")
    private String adminAddresses;

    @Value("${xxl.job.accessToken}")
    private String accessToken;

    @Value("${xxl.job.executor.appname}")
    private String appname;

    @Value("${xxl.job.executor.address}")
    private String address;

    @Value("${xxl.job.executor.ip}")
    private String ip;

    @Value("${xxl.job.executor.port}")
    private int port;

    @Value("${xxl.job.executor.logpath}")
    private String logPath;

    @Value("${xxl.job.executor.logretentiondays}")
    private int logRetentionDays;


    @Bean
    public XxlJobSpringExecutor xxlJobExecutor() {
        log.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppname(appname);
        xxlJobSpringExecutor.setAddress(address);
        xxlJobSpringExecutor.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }

}

（3）设置application.properties 

# no web
#spring.main.web-environment=false

# log config
logging.config=classpath:logback.xml


### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8080/xxl-job-admin

### xxl-job, access token
xxl.job.accessToken=

### xxl-job executor appname
xxl.job.executor.appname=xxx-xxljob
### xxl-job executor registry-address: default use address to registry , otherwise use ip:port if address is null
xxl.job.executor.address=
### xxl-job executor server-info
xxl.job.executor.ip=
xxl.job.executor.port=9999
### xxl-job executor log-path
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
### xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30

（4）配置logback

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="true" scanPeriod="1 seconds">

    <contextName>logback</contextName>
    <property name="log.path" value="/data/applogs/xxl-job/xxx-xxljob.log"/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${log.path}</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${log.path}.%d{yyyy-MM-dd}.zip</fileNamePattern>
        </rollingPolicy>
        <encoder>
            <pattern>%date %level [%thread] %logger{36} [%file : %line] %msg%n
            </pattern>
        </encoder>
    </appender>

    <root level="info">
        <appender-ref ref="console"/>
        <appender-ref ref="file"/>
    </root>

</configuration>

（5）编写Job类

@Component
public class PointJob {

    /**
     * 1、简单任务示例（Bean模式）
     */
    @XxlJob("pointOverdueResetJobHandler")
    public ReturnT<String> pointOverdueResetJobHandler(String param) throws Exception {
        XxlJobLogger.log("pointOverdueResetJobHandler is called");

        for (int i = 0; i < 100; i++) {
            XxlJobLogger.log("beat at:" + i);
            TimeUnit.SECONDS.sleep(1);
        }
        return ReturnT.SUCCESS;
    }
}

（6）部署后，观察控制台，已部署成功：
