Hello, @TsungyingChen

You can mount a DigitalOcean space on your droplet and use it for storage of some of you data. In general, object storage solutions like Spaces are not meant to be accessed like a file system. They are API driven and most often used programmatically. You can check out this tutorial to learn more about object storage and if it’s right for your use case:

https://www.digitalocean.com/community/tutorials/object-storage-vs-block-storage-services#what-is-object-storage

I’ve recently posted a question in the community on how to manage DigitalOcean Spaces using s3cmd:

https://www.digitalocean.com/community/questions/how-to-manage-digitalocean-spaces-using-s3cmd

You can use s3cmd in order to mount the Space to your droplet and from there you can transfer files directly to your Spaces. s3cmd also have a feature to sync directories. In this way you can always make sure that you have all of your latest project files uploaded to your bucket:

You can also use other tools like s3fs in order to mount the space. Also you can mount the Space on multiple droplets, there is no issue in doing that.

You need to do few steps:

1 First is to install s3fs:

sudo apt-get update
sudo apt-get install s3fs

2 Once that is done you need to setup your DigitalOcean Space credentials:

echo <space_key>:<space_token> > ~/.passwd-s3fs
chmod 600 ~/.passwd-s3fs

3 You need to sort the user permissions:

By default, DigitalOcean Space is mounted for root user. Because of that, any files or folders that are created via the web control panel is not accessible by non-root users after it’s mounted, which is not ideal.
To make sure that we can access it via a non-root user, we need to update the config file:

sudo nano /etc/fuse.conf

Uncomment the part that says:

user_allow_other

Next, find out your user’s details by typing the following command:

id

You’ll see an output like this:

uid=1000(sammy) gid=1000(sammy) groups=1000(forge)…

In this case, the user is sammy, so you need to note down the uid and gid of the user for the next step.

4 Mount DigitalOcean Space

First, make a mounting folder:

mkdir <folder>

e.g replace the <folder> with the actual folder you would like to use, the command will be: mkdir space-storage

Then, let’s mount the Space to our new folder:

s3fs <space_name> <folder> -o url=https://sgp1.digitaloceanspaces.com -o use_cache=/tmp -o allow_other -o use_path_request_style -o uid=1000 -o gid=1000

Note: replace the space_name , folder and the uid , gid with your actual space name, created folder and the user IDs received from the id command in step 3

If you want to unmount the space you need execute this command:

fusermount -u <folder>

That’s all for using s3fs with DigitalOcean’s Spaces.

Hope this helps!

Alex

Flexible and scalable data storage is a baseline requirement for most applications and services being developed today. With today's complex deployments, containers, and ephemeral infrastructure, the days of simply saving files to disk on a single server are gone. Cloud providers have developed services to fill the storage needs of modern application deployments, and they mostly fit into two categories: object storage, and block storage.
  • space_test is my folder name

    Example
    echo key:secretkey > ~/.passwd-s3fs
    chmod 600 ~/.passwd-s3fs

    s3fs spacename spacetest -o url=https://sgp1.digitaloceanspaces.com -o usecache=/tmp -o allowother -o usepathrequest_style -o uid=0 -o gid=0

    error show
    s3fs: unable to access MOUNTPOINT space_test: Transport endpoint is not connected

    • Hi, @pranaysoni

      Could you please let me know which version of s3fs that you’re using? You can check the running version using:

      sudo s3fs --version

      Have you tried to unmount and mount the directory again?

      If you want to unmount the space you need execute this command:

      fusermount -u <folder>

      Command to mount

      /usr/bin/s3fs -o allow_other bucketname /s3

      Let me know how it goes.
      Regards,
      Alex

      • s3fs --version

        • The version seems fine. As mentioned have you tried to unmount and mount the directory again. You can check the commands that I’ve posted above.
