The last time I had to do that I used the REX-Ray storage plugin. It officially comes with DigitalOcean Block Storage support.

I’ll try to walk you through the whole process here:

  • Prerequisites:


To install the REX-Ray Docker plugin run the following:

  • Change the YOUR_DIGITALOCEAN_TOKEN with your actual DigitalOcean Token

  • You can change the nyc1 part with the region that you would like your Block Storage to be deployed at

  • You can change the LINUX_VOLUME_FILEMODE according to your needs

To check if the plugin was installed successfully run:

docker plugin ls


ID                  NAME                 DESCRIPTION                               ENABLED
fcb931b51f5a        rexray/dobs:latest   REX-Ray for Digital Ocean Block Storage   true

Creating a volume

Once you have the REX-Ray plugin installed, you can go ahead and create a volume:

docker volume create --name=my-dobs --opt=size=10 --driver=rexray/dobs
  • You can change the my-dobs with the name that you would like to use for your volume

  • The --opt=size=10 indicates the size of the DigitalOcean block storage that you would like to be created

To check if the volume was created successfully run:

docker volume ls


DRIVER               VOLUME NAME
rexray/dobs:latest   my-dobs

This would also create a new volume under your DigitalOcean account. To see it you just go to your DO control panel at then from the menu on the right click on Manage and then click on Volumes. There you would be able to see the volume with the name that you’ve specified as a --name argument and the size you’ve selected.

Mounting the new volume to a container

Then to mount the new volume just run the following:

docker run -ti -v my-dobs:/my-folder busybox

This would attach you to the container straight away. You can also check if this worked by running the following:

df -h | grep my-folder

The out put should look something like this:

/dev/sda                  9.8G     36.0M      9.2G   0% /my-folder


For more information about the plugin you can visit their official GitHub repo here:

Hope that this helps! Regards, Bobby

The repo is not being maintained as much anymore so be careful.
