To get the root password run:
export MONGODB_ROOT_PASSWORD=$(kubectl get secret --namespace default mongodb-1577466908 -o jsonpath="{.data.mongodb-root-password}" | base64 --decode)
To connect to your database run the following command:

To connect to your database from outside the cluster execute the following commands:
kubectl port-forward --namespace default svc/mongodb-1577466908 27017:27017 &
