Now let’s start deploying our application stack with the PostgreSQL database.
Let’s install PostgreSQL using the Bitnami’s Helm chart.
# adds the bitnami helm repo
helm repo add bitnami https://charts.bitnami.com/bitnami
# updates helm index
helm repo update
# installs the postgresql
helm install postgresql bitnami/postgresql \
--set global.postgresql.auth.username=youruser \
--set global.postgresql.auth.password=yourpassword \
--set global.postgresql.auth.database=dbname
# lists the helm charts installed
helm list
The Helm chat will generate a Kubernetes Service with the database address and a Kubernetes Secret with the database password. Let’s find them!
# gets the postgresql service
kubectl get svc postgresql
# describes the postgresql secret
kubectl describe secret postgresql
Based on the commands output, you can use the following addresses to access the database:
# if the app is on the default Kubernetes namespace
postgresql:5432
# to access the database from any namespace
postgresql.default.svc.cluster.local:5432
