Exporting Data for Sharing
Jelastic PaaS provides extended support for files sharing over the NFS protocol between instances inside of the same account. The dedicated UI panels are available in the dashboard to simplify the required export from a server (described in this guide) and mount on client operations. Herewith, you only need to perform either of these actions, and the platform will automatically apply the correlated configuration on the appropriate second instance.
You can share any directory inside your container with any other node at your account.
Open the configuration manager for your storage (i.e. where files are physically located), switch to the Exports section, and click the Export button at the top pane.
The appropriate Export Directory tab will be opened.
Here, you’ll need to specify the following information:
- From NFS - choose the required node inside the current environment layer via the drop-down list
- Path - type an absolute path to the exported folder (or choose it from your favorites)
- To Container(s) - select target layer from the automatically fetched list of environments on your account
- Path - provide a path to the location through which the shared data should be available on the target node(s)
- Mount to all nodes - use this switcher to set the same mount for the whole layer (disable to mount to a single node)
- Read Only - turn the switcher on to restrict editing of the exported data at client node(s) (by default, the read & write permissions are provided)
Click Add to proceed.
The same form can be accessed directly from the node’s file manager, using the appropriate Export option in the folder’s context menu:
- In a moment, this exported folder will appear in the list.
That’s all! During the operation, the appropriate mount point on the target node(s) is configured automatically by the platform so that you can immediately start working with your shared data without any additional steps required.
Beside exporting directories, the Exports section allows managing existing records.
- All directories shared from this container to any node on the same platform are displayed here (the externally exported data won’t be shown).
You can quickly jump to any of the exported folders by hovering over the required record and selecting the Navigate to directory option from the Additionally list.
- In order to get the exact location and target node details for the exported directories, expand the appropriate record.
The following information can be found here:
- Name - shows stack name and ID of the node(s), where the exported folder is mounted (hover over for additional details on the appropriate environment or to unmount this record via the Additionally list)
- Client Path - provides a path to the folder, where shared data can be accessed at the remote node
- Permission - displays access permissions for the corresponding client (rw - read-write; ro - read-only)
- At the tools panel above the list, you can find several buttons, which are intended to help you with managing your exports on the current container.
- with the Export option, you are able to share any directory inside the container with any other node at your account
- the Unmount button stops data sharing with the selected client node
After confirmation, the corresponding record will be removed from the list, and the appropriate data will become unavailable at the chosen instance.
- the Configuration button redirects to the etc/exports file, where you can check and, if needed, manually edit the list of exports (shared folders, client addresses, additional parameters)
- you can Refresh the list with the same-named button to get the most recent shares state
- the Documentation button on the far right of the panel redirects to the current documentation page
