elastic-job-lite-console 部署到k8s集群

大爷来玩呀你懂得

[elastic-job-lite-console 部署到k8s]

1.准备构建镜像的文件

[root@jenkins elastic-job]# ls
Configurations.xml      Dockerfile     elastic-job-lite-console-2.1.5.tar.gz       run.sh

[root@jenkins elastic-job]# cat Dockerfile
FROM harbor.reg/library/centos7-jdk:8u221

#构建参数

#环境变量
ENV WORK_PATH /data/work/
ENV LANG=zh_CN.UTF-8 
LANGUAGE=zh_CN:zh 
LC_ALL=zh_CN.UTF-8

#设置时区
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && 
echo "Asia/Shanghai" > /etc/timezone && 
localedef -c -f UTF-8 -i zh_CN zh_CN.UTF-8
ADD elastic-job-lite-console-2.1.5.tar.gz $WORK_PATH
COPY run.sh /
WORKDIR $WORK_PATH
RUN chmod +x /run.sh
CMD ["sh","/run.sh"]

[root@jenkins elastic-job]# cat run.sh
sh +x elastic-job-lite-console-2.1.5/bin/start.sh -p 8899

##  2.构建镜像并上传 

> docker build -t harbor.reg/library/elastic-job-lite:2.1.5 .

> docker push harbor.reg/library/elastic-job-lite:2.1.5

##  3.创建k8s  yaml 文件
 deploy.yaml

cat deploy.yaml

maxUnavailable: 0 #滚动升级时允许的最大Unavailable的pod个数
