It connects to my database when running the application on my pc, it also connects after creating and running as a Docker image, running on a Ubuntu VM on my PC. It does not connect to Mongodb Atlas when running as a Kubernetes deployment on Minikube. There must be a configuration step im missing, but i just dont know what.

问题 Using MongoDB Charts, how can I chart cumulative growth? Using the _id value of a document which contains the information of when it was created, I'd like to chart the number of documents in my database over time. E.g., if in July 10 documents were created, and in August another 10 were created, then the chart should display 10 for July and 20 for August. It's easy to bin document creation dates per months (see below example), but I'd like to turn this into a cumulative growth chart. MongoDB

问题 During my investigation on compatible DBs for IoT data storing I looked into MongoDB and pricing is a little bit confusing. Just wondering what is the difference between MongoDB Atlas and MongoDB Atlas for AWS as they both work on AWS? And what is the right way to run MongoDB Atlas on AWS? 回答1: As far as I can see, they both should mostly be similar : MongoDB Atlas : You can directly go to MongoDB-Atlas portal & create a MongoDB cluster(a cluster will usually be 3-shard/node replica set on
