** Please be patient while the chart is being deployed **

MongoDB can be accessed via port 27017 on the following DNS name from within your cluster:

    mongodb-1577466908.default.svc.cluster.local

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 &
    mongo --host 127.0.0.1 --authenticationDatabase admin -p $MONGODB_ROOT_PASSWORD
