A handy file cache service

$ wget http://localhost:getFile?url=$YOUR_REMOTE_URL

• Cache for hot content from remote cloud object storage(or public image)
• Extremely simple start and stop command, no heavy configuration
• Cache item persistence ability: previous items will be reloaded after server restart

Detailed design document

• Download Program Image: https://riverpass.oss-cn-shanghai.aliyuncs.com/images/oss.tar.
• Download Database Config:https://riverpass.oss-cn-shanghai.aliyuncs.com/images/data.tar
• Load Images

docker load -i oss.tar

• Load database config in server folder

tar -xvf data.tar

• How to use
  • Enter server folder, run ./oss_docker_start.sh 100, '100' means cache size 100MB. Cache data default flushes to server/localfs_oss/ folder.
  • Use wget <url> command, replacing host path by localhost and cache port. eg.: wget http://localhost:10009/getFile?url=https://raw.githubusercontent.com/open-mmlab/mmdeploy/master/resources/mmdeploy-logo.png
  • Run ./oss_docker_stop.sh to stop the cache. Data will be left on disk.
  • Run ./oss_docker_restart.sh to restart the cache, data and their metadata will be loaded.
• How to build
  • Enter server/holder folder, run ./oss_start.sh to build the go program and start server for debug.
