To accomodate the case where you are using Magento plugins which are incompatible with assets being stored in the database, there is the option to run an NFS server for shared file storage.
Important: The NFS node is not highly available. If NFS is used it can become a single point of failure for your environment. For this reason we recommend using database storage for assets unless there is no other option.
Enabling and Disabling NFS
To enable NFS on an environment run
fleet env nfs <environment> ON
A new NFS instance will be created. This will take a few minutes before it is ready.
Note: Only releases loaded after NFS is enabled will be able to access NFS.
Later if you wish to disable NFS, you can run
fleet env nfs <environment> OFF
Once NFS is enabled for an environment, any releases newly loaded into the environment will have a shared NFS volume available at /nfs/shared.
In order to make use of NFS for storage of assets, you will need to direct Magento to use the shared volume. The easiest way to do this would be to create symbolic links in your codebase controlling which directories are on the shared volume.
Any required subdirectories within the NFS volume should be configured using boot scripts.
The NFS volume is snapshotted daily via the snapshot mechanism. You can additionally call the snapshot command to create snapshots manually if you would like snapshots taken more often or at a particular time.
To recover to a particular snapshot for an environment, you will need to first disable NFS for that environment, then enable it again, passing the snapshot to use to restore. This process should take 15 minutes or so, during which NFS storage would not be available.
