Postgres
Canvas requires a few fields in order to connect to your Postgres instance:
- 1.Host
- 2.Port
- 3.Database
- 4.Username and Password
We'll go through each.
The public address of your Postgres instance. If you block public access to your database you will need to whitelist the following IP addresses in your database's security group:
- 44.224.89.3
- 35.80.194.138
- 44.241.79.133
Also available in the AWS console. This is
5432 by default.The database that you would like to work with in Canvas.
In order to display your data Canvas requires a user with usage grants on any schemas you want to access and select grants on any tables and views you want to access. Following the principle of least privilege, we recommend creating a user for Canvas with the minimum set of permission necessary. The following script will create a user and grant it permissions for the schema
public:CREATE USER 'canvas_user' PASSWORD 'your-strong-password';
// Grant access to schema "public". Repeat this for any other schemas you want to access
GRANT USAGE ON SCHEMA "public" TO canvas_user;
GRANT SELECT ON ALL TABLES IN SCHEMA "public" TO canvas_user;
// This grants access to all future tables
ALTER DEFAULT PRIVILEGES IN SCHEMA "public" GRANT SELECT ON TABLES TO canvas_user;
