Volumes

Objective

This guide explains how to use Volumes on Ruk-Com Cloud PaaS, with ordered procedures and practical verification points.

Before you begin

• Sign in with an account permitted to manage the relevant environment.
• Confirm the target environment, region and resources before saving changes.
• Create a backup or rollback plan before changing a production system.

The Volumes section is used to compile a list of currently installed containers. It is designed to maintain data independent of the container circuit and display it in view of the path to the appropriate mount points within the node:

Storing data within volumes allows various internal operations (e.g.Container installationFor reliability, individual volumes are archived in a separate.tar.gz file and moved toReal serverTemporary (such as duringredeploy) When the operation is complete, the custom volumes will be returned to the updated node, which will make your data more complete.

In the next section we will discuss how to add custom volumes for your container and types of data installations.data mountingRuk-Com Cloud PaaS is prepared at the Local Filesystem, separating data only at the Master Container layer or NFS Server (external server).

Operating Custom Volumes

By default the predefined volumes (such as those configured within appropriate templates and automatic settings during container creation) are displayed in frames.Docker layer settings > Volumes

Additionally, you can set and manage your customized volumes locally on other instances on external platforms or servers. To do this, follow the steps below:

1. Select the buttonAddabove, then four tabs will appear based on the types of volumes you can create:

• Local Filesystem - The specified directory will be used as local storage. Its purpose is to retain data and not depend on the current container cycle. (same as other nodes)

• Data Container- volumes allow connecting data from other layers within your account

• Master Container- Data stored within volumes is placed at the node that created the layer initially, called the "Master Node", and is automatically shared with all remaining instances within the layer.

• External Server- Connect data to external NFS servers (either your custom third-party storage or Ruk-Com CloudContainers on other platforms)

When you specify all parameters for the connection typemount pointthat has already been selected (You can click on the link to see additional settings details) then clickAddto finish the configuration.

2. Select the Edit button above to edit (or double-click a cell to edit immediately) and you can change some volumes settings:

At this pointLocal Pathcannot be changed But it is still possible to change the installation method. (by moving to another tab) or adjust access permissions (switch toRead Only)

Note:

• Before deleting, make sure the volume is empty of sensitive data. It will be permanently deleted.
• Predefined volumes (such as default) cannot be deleted, but they can still be edited.
• If you want to delete the volume but keep it connectedmount pointYou can uncheck Unmount path.

After that, don't forget to select Apply button to save all changes. in the Docker general settings page and if necessary, select Apply again in the topology wizard (if editing an existing environment).
