cronicle 后端存储是可配置的 ，通过使用不同的存储配置，我们可以解决多实例部署以及数据共享的问题
cronicle 的后端存储模型，设计的特别方便，包含了基于文件的，基于s3 的，同时我们也可以开发自己的
存储引擎
环境准备
- docker-compose 文件
version: "3"
services:
s3:
image: minio/minio
command: server /data
ports:
- "9000:9000"
environment:
- "MINIO_ACCESS_KEY=dalongapp"
- "MINIO_SECRET_KEY=dalongapp"
volumes:
- "./data:/data"
cronicle:
build: ./
hostname: master
image: dalongrong/cronicle
volumes:
- "./config.json:/opt/cronicle/conf/config.json"
ports:
- "3012:3012"
cronicle2:
build: ./
hostname: cronicle2
image: dalongrong/cronicle
volumes:
- "./config.json:/opt/cronicle/conf/config.json"
ports:
- "3013:3012"
cronicle3:
build: ./
hostname: cronicle3
image: dalongrong/cronicle
volumes:
- "./config.json:/opt/cronicle/conf/config.json"
ports:
- "3014:3012"
- cronicle dockerfile
添加了aws sdk
FROM node:12.10.0-stretch-slim
LABEL AUTHOR="rongfengliang"
LABEL EMAIL="[email protected]"
RUN npm config set registry https://registry.npm.taobao.org
RUN curl -s https://raw.githubusercontent.com/jhuckaby/Cronicle/master/bin/install.js | node
RUN cd /opt/cronicle && npm install aws-sdk
EXPOSE 3012
ENTRYPOINT ["tail", "-f", "/dev/null"]
- 存储配置
config.json ，以下截取部分关于存储的配置
"Storage": {"engine": "S3",
"AWS": {"accessKeyId": "dalongapp",
"secretAccessKey": "dalongapp",
"region": "us-east-1",
"correctClockSkew": true,
"endpoint": "s3:9000",
"sslEnabled": false,
"s3ForcePathStyle": true,
"maxRetries": 5,
"httpOptions": {"connectTimeout": 5000,
"timeout": 5000
}
},
"S3": {"keyPrefix": "cronicle",
"fileExtensions": true,
"params": {"Bucket": "cronicle"
}
}
}
启动&&运行
- 启动
docker-compose up -d
- 创建s3桶
通过UI - 启动master
docker-compose exec cronicle /opt/cronicle/bin/control.sh setup
docker-compose exec cronicle /opt/cronicle/bin/control.sh start
- s3 内容
- 启动slave
docker-compose exec cronicle2 /opt/cronicle/bin/control.sh start
docker-compose exec cronicle3 /opt/cronicle/bin/control.sh start
- 添加slave 节点
- 配置一个简单的调度任务
- 执行调度效果
说明
以上是一个简单的基于minio s3 实现的配置共享，实际上基于s3 我们可以配置cronicle 的多master
