minback-mongo

Minio Backup container for MongoDB

Features

  • Dumps a single MongoDB database to an S3 bucket
  • Lightweight and short lived
  • Simple and readable implementation

Example

docker run --rm --env-file backup.env minback/mongo my_db -h mongoserver1

backup.env

MINIO_SERVER=https://play.minio.io/
