Start Kong Gateway Securely

To secure the Admin API or Kong Manager, a Super Admin account is required.

The Super Admin has the ability to invite other Admins and restrict their access based on Permissions of Roles within Workspaces.

The first Super Admin account is created during database migrations following the guide below. It may only be added once.

Prerequisites

After installing Kong Gateway, either modify the configuration file or set environment variables for the following properties:

• Enabling RBAC authorization and authentication, add the following settings to kong.conf: database=postgres and enforce_rbac=on.

• enforce_rbac will force all Admin API requests to require a Kong-Admin-Token. The Admin associated with the Kong-Admin-Token must have adequate Permissions in order for the request to succeed.

• If using Kong Manager, select the type of authentication that Admins should use to log in. For the purpose of this guide, admin_gui_auth may be set to basic-auth. See Securing Kong Manager for other types of authentication.

Configure RBAC with basic authentication:

Important: The settings below are intended for non-production use only, as they override the default admin_listen setting to listen for requests from any source. Do not use these settings in environments directly exposed to the internet.

If you need to expose the admin_listen port to the internet in a production environment, secure it with authentication.

database = postgres
enforce_rbac = on
admin_gui_auth = basic-auth
admin_gui_session_conf = {"secret":"secret","storage":"kong","cookie_secure":false}
admin_listen = 0.0.0.0:8001, 0.0.0.0:8444 ssl

Kong Manager uses the Sessions plugin in the background. This plugin (configured with admin_gui_session_conf) requires a secret and is configured securely by default.

• Under all circumstances, the secret must be manually set to a string.
• If using HTTP instead of HTTPS, cookie_secure must be manually set to false.
• If using different domains for the Admin API and Kong Manager, cookie_samesite must be set to off.

Learn more about these properties in Session Security in Kong Manager, and see example configurations.

Step 1

Set a password for the Super Admin. This environment variable must be present in the environment where database migrations will run.

Important: Setting your Kong password (KONG_PASSWORD) using a value containing four ticks (for example, KONG_PASSWORD="a''a'a'a'a") causes a PostgreSQL syntax error on bootstrap. To work around this issue, do not use special characters in your password.

export KONG_PASSWORD=<password-only-you-know>

This automatically creates a user, kong_admin, and a password that can be used to log in to Kong Manager. This password may also be used as a Kong-Admin-Token to make Admin API requests.

Note: only one Super Admin may be created using this method, and only on a fresh installation with an empty database. If one is not created during migrations, revert configuration in Prerequisites, and invite a new user as a Super Admin in Kong Manager.

Future migrations will not update the password or create additional Super Admins. To add additional Super Admins, invite a new user as a Super Admin in Kong Manager.

Step 2

Issue the following command to prepare your data store by running the Kong migrations:

kong migrations bootstrap [-c /path/to/kong.conf]

Step 3

Start Kong:

kong start [-c /path/to/kong.conf]

Note: the CLI accepts a configuration option (-c /path/to/kong.conf) allowing you to point to your own configuration.

Step 4

To test that Kong Gateway has successfully started with a Super Admin, visit Kong Manager’s URL. By default, it is on port :8002.

The username is kong_admin and the password is the one set in Step 1.
