Accessing Postgres

The Postgres database runs as the Postgres microservice on a Hasura cluster. The Postgres microservice can only be accessed from within the Hasura cluster and is not exposed to the outside world. (The Data microservice provides APIs over the Postgres database which are exposed to the outside).

To connect to postgres from another microservice within the cluster, see: Connecting to Hasura Postgres database from microservices.

Although, you can manually access the Postgres database directly via a secure tunnel using the following options:

Note

All the data is stored in a database called hasuradb in Postgres.

Port Forward

SSH

To get direct CLI access to the database, you can port forward from the postgres microservice to your local system.

Run the following hasura CLI command from your project directory:

# Open a tunnel to postgres
hasura microservice port-forward postgres -n hasura --local-port 6432

The above command will allow direct access to postgres at localhost:6432.

Now, you can run psql (or any other postgres client) from your localhost to access the hasuradb database:

psql -U admin -h localhost -p 6432 -d hasuradb

To get direct CLI access to the database, you can exec (equivalent to SSH) into the postgres microservice container.

Run the following hasura CLI command from your project directory:

$ hasura ms exec postgres -n hasura -ti -- /bin/bash
root@postgres-3391217220-6jbq7:/$ # You can now run psql, pg_dump and other commands
