3. Install PostgreSQL

NLX uses PostgreSQL to store various data, including the configuration of the various components and transaction logging. In this section, we install PostgreSQL using the Bitnami Helm chart.

Install PostgreSQL by running:

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update

helm install \
  postgresql bitnami/postgresql \
  --namespace nlx \
  --version 11.9.8 \
  --set auth.database=nlx_management

Then check if PostgreSQL is running properly by running:

kubectl get pods -n nlx

The output should look like this (make sure the status is Running).

NAME                      READY   STATUS    RESTARTS   AGE
postgresql-postgresql-0   1/1     Running   0          ?s

Make sure you get the password for PostgreSQL and write it down somewhere, we'll need this password later in this guide. Get the password with the following command:

kubectl get secret --namespace nlx postgresql -o jsonpath="{.data.postgres-password}" | base64 -d

Save this password somewhere without the closing % sign
