Volume

Volume enables you to have persistent storage in your services. It is a resource that belongs to a Project;

To view all volumes of a project:

• Open a project by choosing it in Projects page,
• Use Volumes link accessible inside the sidebar located at left.

You can manually create volumes and mount them into your services or create volumes while creating a custom service. When you create a web application service, Yelken automatically creates necessary volumes for your services. Unfortunately, it is not possible to manually mount a volume into a web application service.

To create a new volume, navigate to Volumes page and use the Create Volume button. Then you need to provide a few information:

1. Name: specify a name for your volume. You can change it later under the Volume Settings page.
2. Volume Size: specify size of the volume in terms of GigaBytes (GB). You can specify a size between 1 GB and 20 GB.

Cloning Volume

By cloning a volume, you can take snapshot of its content and create a new volume with the snapshot. You can then use this new volume in your services.

1. Name: specify a name for your volume.
2. Volume Size: specify size of the volume in terms of GigaBytes (GB). The new volume size must be greater than or equal to the source volume size.
