Docker mount S3 container

There is different aproaches depending on what you want to acomplish, but here is how I did it using s3fs-fuse

I created a docker image based on ubuntu and also- included some useful dependencies(based on my requirements)- Install aws cli- Install s3fs-fuse- Mount s3 in a directory

and the start script specified should be :

start-script.sh

#!/bin/bashs3fs $S3_BUCKET_NAME $S3_MOUNT_DIRECTORY

Then build your image and if you create a file into the directory that you specified it should also be reflected on the s3 console and viceversa.

I have a more detailed explanation here with a working example: https://github.com/skypeter1/docker-s3-bucket

There doesn't seem to out-of-box support of Amazon S3 in the popular container storage solutions like Flocker and EMC REX-Ray. However if you're open to storing your data on Amazon EBS volumes, then EMC REX-Ray allows you to create, mount and take snapshots of your volumes.

Of course, the approach you suggested works perfectly as well. You can install the AWS CLI on the host running your containers and write a simple cron job that copies the data in the host directory mapped to your container volume to your S3 bucket.
