CI/DevOps: Looking for an Kubernetes expert (MongoDB, Websockets, NodeJS, Google Cloud, Igness)

Hi we created an Kubernetes with the following steps on Google cloud. - kubectl create namespace live - helm init - helm install --namespace=live --name livedb stable/mongodb-replicaset - helm install --namespace=live --name=lives3 --set accessKey=xxx,secretKey=xxxx,persistence.size=40Gi stable/minio Then we get our: - MongoDB Replica - Igness (Https) - Minio for the files Here we host: - Webserver (with an NodeJS application and docker image) - Websockets to connect (ws) After deploying, it is running. But we have some doubts if its the best setup because we experience some problems. Problems we experience: 1 - Its not using the same instance for generating the PDF, and downloading. So often it is showing an error. If we run it on 1 instance it is all working smooth. 2 - Sometimes, for some browsers, App is login out after a few minutes. (maybe because session?) 3 - Response is slow What we would like: - Have an consult to go trough the full YALM files, and steps we do, reproduce them on an blanc new cluster of us, and give suggestions how to improve it. - Update the scripts / steps we have to take, to take a proper regular backup for the cluster. What do you get from us: - The files we use for deploy: [login to view URL] and [login to view URL]
