I  am trying to deploy a MongoDB replication followning this tutorials . When I start the replicas, I get the following logs:

When I run kubectl describe I got this output:

2020-05-22 08:27:29.078 main.go:81       FATAL  Error connecting to mongodb: no reachable servers

I am using kubenetes 1.17

Thank you,
