Mounts an s3 bucket inside a docker container

This is a simple docker dontainer based on ubuntu that mounts an s3 bucket in a directory in the filesystem of the image, using s3-fuse https://github.com/s3fs-fuse/s3fs-fuse/

Clone the repo in your localhost

git clone https://github.com/skypeter1/docker-s3-bucket

Then, go to the Dockerfile and modify the next values with yours

First go to line 22 and set the directory that you want to use, mine is var/www

WORKDIR /var/www

and also the name of the directory that you will use as your mountpoint on line 23, (I used s3 as name for my example)

RUN mkdir s3

Include your aws credentials on line 26 and 28, for more info about how to create AWS secret access key id you can check https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys

ARG AWS_ACCESS_KEY=YOURAWSACCESSKEY
ARG AWS_SECRET_ACCESS_KEY=YOURAWSSECRETACCESSKEY

The idea is to mount an s3 storage inside a directory that we will create or select if it's already avaliable on our current ubuntu filesystem. Enter the name of the directory that you have choose as the mountpoint for your s3 bucket

ARG S3_MOUNT_DIRECTORY=/var/www/s3

I have included a start-script.sh file that will kickstart the mounting from within the container Bear in mind that this will only work if you run docker on privileged mode

Once you've modified the Dockerfile let's build the image Go to the root of the directory and

docker build--no-cache .

You will also want to add a tag to your image id once you've built it like:

docker tag ff47cca76424 mydockerhubrepo/s3:latest

Then run the container in privileged mode like this

docker run -d --privileged -i ff47cca76424 bash

If you want to check the connection just ssh into to the container using the container id (you can check this running docker ps)

docker exec -it b6c43f7d1d72 bash

and check the mounted filesystem

df -h

You should be able to see a s3fs type of filesystem and mounted on your selected location, in the case of this example /var/www/s3

Go to your directory and create a simple index.html

cd /var/www/s3
echo Hello world > index.html

Now go to the s3 console on AWS and you should be able to see your recently created file
