Examples

Run container with cron job (once a day at 1am), save backup to /path/to/target/folder, upload backups to AWS S3 folder:

docker run -d \
  -v /path/to/target/folder:/backup \
  -e 'MONGO_URI=mongodb://mongo:27017' \
  -e 'CRON_SCHEDULE=0 1 * * *' \
  -e 'TARGET_S3_FOLDER=s3://my_bucket/backup/' \
  -e 'AWS_ACCESS_KEY_ID=my_aws_key' \
  -e 'AWS_SECRET_ACCESS_KEY=my_aws_secret' \
  istepanov/mongodump:4.2

Same, but runs once, no cron job:

docker run -ti \
  -v /path/to/target/folder:/backup \
  -e 'MONGO_URI=mongodb://mongo:27017' \
  -e 'TARGET_S3_FOLDER=s3://my_bucket/backup/' \
  -e 'AWS_ACCESS_KEY_ID=my_aws_key' \
  -e 'AWS_SECRET_ACCESS_KEY=my_aws_secret' \
  istepanov/mongodump:4.2

Run container with cron job (once a day at 1am), upload backups to AWS S3 folder, do not create local backups:

docker run -d \
  -e 'MONGO_URI=mongodb://mongo:27017' \
  -e 'CRON_SCHEDULE=0 1 * * *' \
  -e 'TARGET_FOLDER=' \
  -e 'TARGET_S3_FOLDER=s3://my_bucket/backup/' \
  -e 'AWS_ACCESS_KEY_ID=my_aws_key' \
  -e 'AWS_SECRET_ACCESS_KEY=my_aws_secret' \
  istepanov/mongodump:4.2
