CREATE NETWORK POLICY

Creates a new network policy in TiDB Cloud Lake.

Syntax

CREATE [ OR REPLACE ] NETWORK POLICY [ IF NOT EXISTS ] <policy_name>
    ALLOWED_IP_LIST = ( 'allowed_ip1', 'allowed_ip2', ... )
    [ BLOCKED_IP_LIST = ( 'blocked_ip1', 'blocked_ip2', ...) ]
    [ COMMENT = 'comment' ]

Examples

This example demonstrates creating a network policy with specified allowed and blocked IP addresses, and then associating this policy with a user to control network access. The network policy allows all IP addresses ranging from 192.168.1.0 to 192.168.1.255, except for the specific IP address 192.168.1.99.

-- Create a network policy
CREATE NETWORK POLICY sample_policy
    ALLOWED_IP_LIST=('192.168.1.0/24')
    BLOCKED_IP_LIST=('192.168.1.99')
    COMMENT='Sample';

SHOW NETWORK POLICIES;

Name         |Allowed Ip List          |Blocked Ip List|Comment    |
-------------+-------------------------+---------------+-----------+
sample_policy|192.168.1.0/24           |192.168.1.99   |Sample     |

-- Create a user
CREATE USER sample_user IDENTIFIED BY 'datalake';

-- Associate the network policy with the user
ALTER USER sample_user WITH SET NETWORK POLICY='sample_policy';
