Openshift或者K8S上部署xxl-job

本案例以版本2.3.0为例 1. 源码编译成jar包

source code: github /xuxueli/xxl-job/blob/2.3.0/

这里我们会得到两个jar包：xxl-job-admin-2.3.0.jar和xxl-job-executor-sample-springboot-2.3.0.jar

2. 初始化mysql数据库

sql code: github /xuxueli/xxl-job/blob/2.3.0/doc/db/tables_xxl_job.sql

3. 构建镜像

xxl-job-admin参考： github /xuxueli/xxl-job/blob/2.3.0/xxl-job-admin/Dockerfile

FROM openjdk:8-jre-slim MAINTAINER xuxueli ENV PARAMS="" ENV TZ=PRC RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone ADD target/xxl-job-admin-*.jar /app.jar ENTRYPOINT ["sh","-c","java -jar $JAVA_OPTS /app.jar $PARAMS"]

xxl-job-executor-sample-springboot参考： github /xuxueli/xxl-job/blob/2.3.0/xxl-job-executor-samples/xxl-job-executor-sample-springboot/Dockerfile

FROM openjdk:8-jre-slim MAINTAINER xuxueli ENV PARAMS="" ENV TZ=PRC RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone ADD target/xxl-job-executor-sample-springboot-*.jar /app.jar ENTRYPOINT ["sh","-c","java -jar $JAVA_OPTS /app.jar $PARAMS"]

build镜像后上传至自己的harbor镜像仓库。

4. 开始部署

job-admin的yaml部署文件：

job-executor部署的yaml:
