Administrator's Guide - Bucket Management

Lyve Cloud allows you to store objects (like files) in buckets (like folders). Before you add or store any object, you must create a bucket. When you create a bucket, you must specify the region where you want to create the bucket.

Role-based access to buckets

Bucket access levels are defined by the user roles. The following table describes console access to bucket features based on the user's role:

Creating buckets

To create a bucket:

  1. On the left-hand menu, select Buckets.
  2. On the Buckets page, select Create Bucket.

  1. Enter the bucket name:

Remember the following while creating a bucket name:

  1. The bucket name must be unique across all of Lyve Cloud.
  2. A bucket name containing a dot (.) is not allowed.
  3. After you create a bucket, you cannot change the bucket name.
  1. Select the region (metro) from the drop-down, where you want the bucket to reside. For more information, see Understanding Global Accounts.
  • US - Virginia (us-east-1)
  • US - California (us-west-1)
  • AP - Singapore - (AP-Southeast-1)
 Note—You must create your first bucket in a region, using the console.
  1. (Optional) Enable Object Immutability. For more information, see Using object immutability.

If Object Immutability is not enabled when a bucket is created, you cannot turn it on later. However, if you switch it on while creating a bucket, you can later switch it off and on again as needed.

If you enable Object Immutability, you can also set a duration to retain the objects. For more information, see Setting duration.

  1. After you create a bucket, it is listed on the Buckets page.
 Note—Sometimes there may be a delay in creating a bucket.

Editing bucket properties

The Buckets page displays the bucket list. It also displays the labels for each bucket, such as Immutable, Versioned, and Logged. For more information on the labels, see Using object immutability and Administrator's Guide - Audit Log Management.

To edit a bucket:

  1. On the left-hand menu, select Buckets.
  2. On the Buckets page, choose and select the name to edit.
  3. Perform any of the following actions in the bucket properties:
  • S3 endpoint URL allows copying the S3 endpoint URL to the clipboard. This URL is used to access the bucket. For more information on the S3 endpoint URL see S3 API endpoints.
  • Object Immutability: You may choose to switch off Object Immutability if it is enabled. For more information, see Using object immutability.
  • Set Duration: You can set duration only when Object Immutability is switched on. Select the pencil icon to edit the retention duration. For more information, see Setting duration.
  • S3 API Audit Logs: Select the toggle switch to enable or disable the audit logs for this bucket. For more information on audit logs, see Administrator's Guide - Audit Log Management. After you enable the audit logs for the selected bucket, the bucket is labeled as Logged, and once you disable the audit logs, the label is removed.
  • Delete Bucket: Select Delete to delete a bucket.

Before deleting a bucket, please make sure to:

  • Delete all data from the bucket.
  • Delete all permissions referencing this bucket. Deleting a bucket associated with bucket permissions is allowed only if you have applied permission to all buckets or all buckets with a prefix in the account.
  • Verify that the bucket is not set as the target bucket for Audit Logs.

Listing buckets

To view the bucket list:

  1. On the left-hand menu, select Buckets.
 Note—This view displays the labels for each bucket, such as Immutable, and Logged. For more information on the labels, see Using object immutability and Administrator's Guide - Audit Log Management.

By default, the Buckets page displays 10 buckets at a time. To increase or decrease the number of buckets per page, select the Rows per page arrow and select 10, 25, 50, or All.

  1. Select the left or right arrow to move between the pages.

The following table displays the description to the column names of the bucket list.

Column Name Description
Name Displays the name of the bucket.
Region Displays the region where the bucket is residing. You can select the region while creating a bucket. For more information, see Creating buckets.
Usage Displays the total amount of data stored in the bucket in KiB, MiB, or GiB.
Created On Displays when the bucket was created in YYYY-MM-DD format.
Immutable, Versioned, Logged Displays the bucket labels.
  • Immutable: The label indicates that the bucket is in compliance mode. To disable the compliance mode, see Editing bucket properties.
  • Versioned: The label indicates that the bucket is versioned. The bucket version is not suspended even after you disable the Object Immutability
  • Logged: The label indicates that audit logs are enabled for the bucket. To disable the audit logs for buckets, see Editing bucket properties.

For more information on these labels, see Using object immutability and Administrator's Guide - Audit Log Management.

Using object immutability

Object immutability prevents objects from being deleted or overwritten by any user or application for a specified retention duration. This is especially useful when you want to meet regulatory data requirements or other scenarios where it is imperative that data cannot be changed or deleted.  Object immutability must be used when you are certain that you do not want anyone, including the Administrator, to delete the objects during their retention duration. When you switch on object immutability, you must also set the duration and specify the defaretention period.

How does versioning work in object immutability?

Versioning allows saving multiple variants of an object in the same bucket. It allows you to preserve, retrieve, and restore every version of an object stored in the bucket. Versioning enables the recovery of objects from any unintended or accidental user actions and application failures.

After switching on object immutability for a bucket, versioning is automatically enabled, Lyve Cloud automatically creates and stores an object version each time when:

  • A new object is uploaded
  • An existing object is overwritten
  • An object is deleted
 Note—Versioning may increase your storage capacity utilization.

For example, if you accidentally delete an object, instead of removing it permanently from Lyve Cloud, this deleted object becomes the current object version. You can then restore the previously available version.

When you create a bucket and switch on object immutability, you can switch off object immutability afterwards. However, versioning cannot be suspended for that bucket.

For example, if you accidentally delete an object, instead of removing it permanently from Lyve Cloud, this deleted object becomes the current object version. You can then restore the previously available version.

When you create a bucket and switch on object immutability, you can switch off object immutability afterwards. However, versioning cannot be suspended for that bucket.

 Note—Switching on object immutability, the bucket is labelled as Immutable and Versioned. Switching off object immutability only removes the Immutable label.

Setting duration

The duration for immutability can be specified in days or years at the object level. When you set the duration, objects remain locked and cannot be overwritten or deleted. By default, the duration is set to 30 days.  Setting the duration applies to individual object versions, and different versions of a single object can have different durations set.

For example, if you set duration to 10 days and then create an object A, object A will have its retention duration set to 10 days. If you later change the duration to 20 days and upload an object A again, in that case:

  • The retention duration for the first version of object A remains to 10 days.
  • The later version of the same object is set to 20 days.

When you place an object in the bucket, Lyve Cloud calculates the retention duration for an object version by adding the specified duration to the object version's creation timestamp. The calculated date is stored in an object's metadata and protects the object version until the retention duration ends. When retention duration ends for an object, you can retain or manually delete an object.

By default, object immutability is switched off, and you can switch it on only while creating a bucket. Once object immutability is switched on, Lyve Cloud automatically enables versioning for the bucket.  For step-by-step instructions see below.

To set object immutability:

  • Enable object immutability when creating a new bucket, see Creating buckets.
  • Optionally, check the Delete objects after the retention duration ends check box.

Managing bucket access permissions

Permissions are used to control access to buckets and define which actions the service accounts are allowed for a bucket. Bucket permission and Policy permission are two options available for granting permission to your buckets.

  • Bucket permission: Bucket permission is used to set Read only, Write only, or All operations permission for selected buckets. Using Bucket permission, you can grant access permissions to your bucket and the objects in the bucket. Only the admin and storage admin can associate permissions for the buckets. The permissions attached to the bucket apply to all of the objects in the bucket. For more information, see Creating bucket access permissions.
  • Policy permission: Policy permission is used for creating policy permission by uploading a JSON file. You can also import a file which is compatible with the AWS IAM policy file. Using the Policy permission, you can allow or deny requests at a granular level based on the elements in the policy, resources, and aspects or conditions of the request. For more information, see Creating policy permissions.

Creating bucket access permissions

You can create bucket permissions without any buckets in the account only if you apply permission to all buckets in the account or all buckets with a prefix.

To create bucket permissions:

  1. On the left-hand menu, select Permissions.
  2. On the Permissions page, select Create bucket permission.
  3. In the Create bucket permission dialog, enter the following:
  • Name: Enter a name for the permission.
  • Which buckets does this permission apply to?: Select any one from the following:
  • One or more existing buckets: Choose one or more buckets from the Buckets list.
  • Buckets: The buckets field is displayed on when you select one or more existing buckets.
  • All buckets in this account with a prefix:

The bucket names must use the same few initial characters. For example, if four unique buckets for customer01 are created, such as customer01rawdata, customer01zipdata, customer01media and customer01, enter a prefix of the bucket names to assign and apply the permission. In this case, use the same beginning characters for each bucket for our prefix, customer01.

 Note

  • Only one prefix is allowed for a single permission.
  • The prefix field allows a maximum of 64 characters.
  • All buckets in the account: Apply permission to all current and future buckets in the account.
  • Actions: Select actions to assign privileges as:
  • All Operations: Allows all operations in all buckets meeting the conditions defined under Which buckets this permission applies to?.
  • Read only: This option allows you to perform a read only operation on one or more selected buckets and its objects.
  • Write only: This option allows you to write objects into the selected buckets without reading them back.

Once you select the desired options, the description of the permissions is displayed for that bucket permission.

  1. Select Create to save the permission for a bucket.

The permissions list page displays all permissions. To manage permissions, see Editing bucket permissions and Deleting bucket permissions.

Creating policy permissions

Lyve Cloud allows the migration of AWS IAM policy files to the Lyve Cloud policy permission, making it simple to start working with service accounts based on existing policies. A policy file uses a JSON file format that is compatible with an AWS IAM policy.

Working with policy files allows you to specify the Condition element. Query the exact request values to determine when a policy is in effect, or list specific actions such as Action: ["s3:GetObject","s3:PuObject"] and specify the Resource element for several buckets and objects. For more information, see Example policy permission file.

How to get an IAM policy file from AWS

You must manually copy policy permission details from AWS IAM policy to use in Lyve Cloud:

  1. Login to AWS Management Console using the credentials.
  2. Select Services on the top left to view the list of services.
  3. Select IAM in Security, Identity, & Compliance.
  4. Under Access Management, select Policies and use the search field to find the relevant policy to copy the policy details.
  5. Select the JSON tab, copy the policy details into a new file, and then save it as a JSON file.

Using policy permission files

The following table lists the mandatory, optional, and invalid elements in a policy permission file.

 Note

  • Invalid elements must be removed from the file before importing, as these elements are not used in the Lyve Cloud policy permission file.
  • Remove tags from elements available in AWS IAM policy, as tags cannot be used in the policy permission file.
Elements Mandatory/Optional/Invalid Description
Statement Mandatory Contains a single statement or an array of individual statements.
Resource Mandatory Specifies object(s) or bucket(s) that is related to the statement.
Effect Mandatory Allows or denies access to the resource.
Action Mandatory Describes specific action(s) that will be allowed or denied.
Version Mandatory It defines the version of the policy language and specifies the language syntax rules that are to be used to process a policy file.
Condition Optional Allows you to specify conditions when a policy is in effect.

The Condition element includes expressions that match the condition keys and values in the policy file against keys and values in the request.

Specifying invalid condition keys returns an error. For more information, see Known Issues.

Sid Optional A statement ID.

The statement ID must be unique when assigned to statements in the statement array. This value is used as sub ID for policy document's ID.
Id Optional A policy identifier, such as UUID (GUID).
Principal Invalid Specifies the service account that is allowed or denied to access a resource.
NotPrincipal Invalid The service accounts that are not specified, are allowed or denied access to the resource.
NotAction Invalid Specifies that it matches everything except the specified list of actions.

If this element is part of the permission file, you need to replace it with the Action element.
NotResource Invalid Specifies that it matches every resource except the available specified list.

If this element is part of the permission file, you need to replace it with the resource element.

 

Example policy permission file

In the following example, the policy permission has three statements:

  • Statement1: Allows object listing with a prefix David in the bucket mybucket. It is done using a Condition element.
  • Statement2: Allows read and write operations for objects with the prefix David in bucket mybucket.
  • Statement3: Denies delete object operation for two resources:

    • All the objects in mybucket/David/*
    • All the objects in mycorporatebucket/share/marketing/*
{   "Version": "2012-10-17",   
"Statement": [     
{        
"Sid": "statement1",       
"Action": ["s3:ListBucket"],       
"Effect": "Allow",       
"Resource": ["arn:aws:s3:::mybucket"],       
"Condition": {"StringLike": {"s3:prefix": ["David/*"]}}     
},     
{       
"Sid": "statement2",       
"Action": [         "s3:GetObject",         "s3:PutObject"       ],       
"Effect": "Allow",       "Resource": ["arn:aws:s3:::mybucket/David/*"]     
},    
{       
"Sid": "statement3",       
"Action": ["s3:DeleteObject"],       
"Effect": "Deny",       
"Resource": ["arn:aws:s3:::mybucket/David/*",       
"arn:aws:s3:::mycorporatebucket/share/marketing/*"]     
}   
] 
}

Use the following policy to limit the bucket access to specific IP's:

{  "Version": "2012-10-17",  
   "Statement": [    
    {
         "Sid": "Sid-1",
         "Action": ["s3:*"], 
         "Effect": "Deny", 
         "Resource": ["arn:aws:s3:::mybucket"], 
         "Condition": {"NotIpAddress": {"aws:SourceIp": ["134.204.220.36/32"]}}    
    },
    { 
     "Sid": "Sid-2", 
     "Action": [ 
      "s3:*"   
    ],    
      "Effect": "Allow", 
      "Resource": ["arn:aws:s3:::mybucket", "arn:aws:s3:::mybucket/*"]  
    } 
   ]
}

To create policy permission:

  1. On the left-hand menu, select Permissions.
  2. On the Permissions page, select Create Policy Permission.
  3. In the Create Policy Permission dialog:
  • Enter a name.
  • Edit the description if desired.
  • Drag and drop a policy permission file, or browse to upload a file.
  • Once the new policy permission file is available, download or replace the existing file.
