Before you use Lake Formation to manage HealthOmics data stores, perform the following Lake Formation configuration procedures.
Topics
Creating or verify Lake Formation administrators
Before you can create a data lake in Lake Formation, you define one or more administrators.
Administrators are users and roles with permissions to create resource links. You set up data lake administrators per account per region.
Create an admin user in the Lake Formation console
-
Open the AWS Lake Formation console: Lake Formation console
-
If the console displays the Welcome to Lake Formation panel, choose Get started.
Lake Formation adds you to the Data lake administrators table.
-
Otherwise, from the left menu, choose Administative roles and tasks.
-
Add any additional administrators as required.
Creating resource links using the Lake Formation console
To make a shared resource that users can query, the default access controls must be disabled. To learn more about disabling default access controls, see Changing the default security settings for your data lake in the Lake Formation documentation. You can create resource links individually or as a group, so that you can access data in Amazon Athena or other AWS services (such as Amazon EMR).
Creating resource links in the AWS Lake Formation console and sharing them with HealthOmics Analytics users
-
Open the AWS Lake Formation console: Lake Formation console
-
In the primary navigation bar, choose Databases.
-
In the Databases table, choose the desired database.
-
From the Actions menu, choose Create resource link.
-
Enter a Resource link name. If you plan to access the database from Athena, enter a name using only lowercase letters (up to 256 characters).
-
Choose Create.
-
The new resource link is now listed under Databases.
Grant access to the shared resource using the Lake Formation console
A Lake Formation database administrator can grant access to the shared resource using the following procedure.
-
Open the AWS Lake Formation console: https://console.aws.amazon.com/lakeformation/
-
In the primary navigation bar, choose Databases.
-
On the Databases page, select the resource link you previously created.
-
From the Actions menu, choose Grant on target.
-
On the Grant data permissions page under Principals, choose IAM users or roles.
-
From the IAM users or roles drop-down menu, find the user to which you want to grant access.
-
Next, under LF-Tags or catalog resources card, select the Named data catalog resources option.
-
From the Tables-optional drop-down menu, select All Tables or the table that you previously created.
-
In the Table permissions card, under Table permissions choose Describe and Select.
-
Next, choose Grant.
To view the Lake Formation permissions, choose Data lake permissions from the primary navigation pane. The table shows the available databases and resource links.
Configuring permissions for AWS RAM resource shares
In the AWS Lake Formation console, view the permissions by choosing Data lake
permissions in the primary navigation bar. On the Data
permissions page, you can view a table that shows the Resource
types, Databases, and ARN that's
related to a shared resource under RAM Resource Share. If you need to
accept an AWS Resource Access Manager (AWS RAM) resource share, AWS Lake Formation notifies you in the console.
HealthOmics can implicitly accept the AWS RAM resource shares during store creation. To accept
the AWS RAM resource share, the IAM user or role that calls the
CreateVariantStore or CreateAnnotationStore API operations must
allow the following actions:
-
ram:GetResourceShareInvitations- This action allows HealthOmics to find the invitations. -
ram:AcceptResourceShareInvitation- This action allows HealthOmics to accept the invitation by using an FAS token.
Without these permissions, you see an authorization error during store creation.
Here is a sample policy that includes these actions. Add this policy to the IAM user or role that accepts the AWS RAM resource share.
{
"Statement": [
{
"Effect": "Allow",
"Action": [
"omics:*",
"ram:AcceptResourceShareInvitation",
"ram:GetResourceShareInvitations"
],
"Resource": "*"
}
]
}
