<![CDATA[Storage limits per-app]]>Is this something that is possible? The use case here is providing testing environments to clients for apps that allow user generated content. This can be useful to make sure a single app does not fill a drive.

We have added a guide documentation for Per-App storage limit.
If there are questions about this guide, or you have feedback on how to improve it further, please let me know.

  • Setup a block storage of appropriate size
  • Then, add it as Cloudron Volume
  • Move app's data directory into the Volume

That way, the app cannot use more data than the volume itself. This does not cover databasize size which is stored outside the volume.

wanna make changes? restore from remote backup.

For a more dynamic setup integrate OpenEBS/MayaData so you can keep attaching additional extent layers or do virtual migrations to different sized container attached storage mounts.

On a standard VPS, this means that we have to create a (big enough) file on EXT4 file system and then format it as XFS. This setup has the usual issues of loopback devices - what size this initial file should be, how to resize it live to increase/decrease storage etc. Not sure how well this performs either.

If you choose to attach container volumes they can be XFS layers with all the nice tools XFS comes with, which EXT4 lacks.

Similarly for attaching external volumes of additional space apart from the default FS the OS is installed on.

I guess this involves creating a user per app.

XFS has pquota - https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/managing_file_systems/assembly_limiting-storage-space-usage-on-xfs-with-quotas_managing-file-systems . EXT4 has prjquota - https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/managing_file_systems/assembly_limiting-storage-space-usage-on-ext4-with-quotas_managing-file-systems

Also, found that there is a --storage-size when using XFS in Docker - https://docs.docker.com/engine/reference/commandline/run/#set-storage-driver-options-per-container

This is very useful especially if we're giving access to our clients who may overuse the storage in some of the apps on Cloudron.

OpenEBS

Yes, but there is a more advanced version at MayaData.

@staff and I have spoken with them before.

I wonder if it works for volumes also. It says it depends on the "volume plugin". Have to investigate. On Cloudron, the data directory is just a normal volume and doesn't use any plugin and it's unclear if that standard thing supports storage-opt.

MayaData.com

I think they use OpenEBS, and as all the distributed storage solutions are complicated to set up, we use Ceph and need a dedicated port on the cluster server for the sync job, not as a requirement but as a need for reasonable performance to be able to use there features.

it can be done with LVM, btrfs or ZFS.
And their relative Docker driver, can be an option with an installation on ubuntu + one of those FS.

This will also help Apps be more distributed and clustered, among other benefits.

As in how does mount a storage directory into a docker container that has a specific size? I can only think of some (sparse) file based loopback filesystem. I don't like that approach and would prefer some other alternative. I haven't looked into recent developments in linux quota system.

You can also check the usage of this disk volume in System info.

Not sure how the implementation would be though

I could see it in the same resources section. Default could be dynamic (unrestricted) and a user could set it to a discrete value.
