This is how I'm running a mongodb client in my kubernetes cluster:
kind: Pod
apiVersion: v1
metadata:
name: mongodb-client
namespace: backup
spec:
containers:
- name: mongodb-client
image: mongo:6.0.6
command: ["tail", "-f", "/dev/null"]
imagePullPolicy: IfNotPresent
Then I'm trying to log into the db:
mongosh --host "mongodb-0.mongodb-headless.databases.svc.cluster.local:27017,mongodb-1.mongodb-headless.databases.svc.cluster.local:27017,mongodb-2.mongodb-headless.databases.svc.cluster.local:27017" --authenticationDatabase admin -u user
I do get the output:
Connecting to: mongodb://<credentials>@mongodb-0.mongodb-headless.databases.svc.cluster.local:27017,mongodb-1.mongodb-headless.databases.svc.cluster.local:27017,mongodb-2.mongodb-headless.databases.svc.cluster.local:27017/?authSource=admin&appName=mongosh+1.10.0
Using MongoDB: 6.0.6
Using Mongosh: 1.10.0
For mongosh info see: https://docs.mongodb.com/mongodb-shell/
To help improve our products, anonymous usage data is collected and sent to MongoDB periodically (https://www.mongodb.com/legal/privacy-policy).
You can opt-out by running the disableTelemetry() command.

The server generated these startup warnings when booting
2023-07-11T08:35:10.635+00:00: vm.max_map_count is too low
------
Why do I get vm.max_map_count is too low and where do I have to configure the value?
