## Connect to PostgreSQL ## Connect to PostgreSQL
We can use the generated secret of the `postgres` robot user to connect to our `acid-minimal-cluster` master running in Minikube: With a `port-forward` on one of the database pods (e.g. the master) you can
connect to the PostgreSQL database. Use labels to filter for the master pod of
our test cluster.
```bash
# get name of master pod of acid-minimal-cluster
export PGMASTER=$(kubectl get pods -o jsonpath={.items..metadata.name} -l application=spilo,version=acid-minimal-cluster,spilo-role=master)
# set up port forward
kubectl port-forward $PGMASTER 6432:5432
```
Open another CLI and connect to the database. Use the generated secret of the
`postgres` robot user to connect to our `acid-minimal-cluster` master running
in Minikube:
```bash ```bash
$ export PGHOST=db_host
$ export PGPORT=db_port
$ export PGPASSWORD=$(kubectl get secret postgres.acid-minimal-cluster.credentials -o 'jsonpath={.data.password}' | base64 -d) $ export PGPASSWORD=$(kubectl get secret postgres.acid-minimal-cluster.credentials -o 'jsonpath={.data.password}' | base64 -d)
$ psql -U postgres $ psql -U postgres -p 6432
``` ```
