Requirements

Database User

This source only uses standard authentication. You will need to create a PostgreSQL user to login to the database with.

Example

kind: sources
name: my-pg-source
type: postgres
host: 127.0.0.1
port: 5432
database: my_db
user: ${USER_NAME}
password: ${PASSWORD}

{{< notice tip >}} Use environment variable replacement with the format ${ENV_NAME} instead of hardcoding your secrets into the configuration file. {{< /notice >}}
