Test for semah answer postgres.yaml
kind: Service
apiVersion: v1
metadata:
name: postgres-svc
namespace: default
spec:
type: ExternalName
externalName: 10.0.2.2
kubectl get svc gives
postgres-svc ExternalName <none> 10.0.2.2 <none> 2m12sSpring boot app deployement logs give
IOException occurred while connecting to postgres-svc.external.svc:5432
java.net.UnknownHostException: postgres-svc.external.svcIf you are trying to connect to DB installed on your local machine and not in kubernetes it is normal to have this error because localhost inside pod this not means your local machine , so can you tell where your db is running ?
try this as you confirmed that you run in local :
apiVersion: v1
kind: Service
metadata:
name: mysql-db-svc
spec:
ports:
- port: 5432
and add endpoint to this service :
apiVersion: v1
kind: Endpoints
metadata:
name: mysql-db-svc
subsets:
- addresses:
- ip: 10.0.2.2
ports:
- port: 5432then access it using :
url=jdbc:postgresql://mysql-db-svc/databasename
