Helm: Is it possible to increase de number of replica?

Question and Answers Installation
#1

Hi,

We have appsmith install in my cluster and we are using a external database. I change de replica count in the helm chart, but the change is not reflect in the cluster. I also try by enabling autoscaling with min and max replicas.

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: scoladmin
  namespace: default
spec:
  interval: 1m
  chart:
    spec:
      chart: appsmith
      version: "1.5.3"
      sourceRef:
        kind: HelmRepository
        name: appsmith
        namespace: flux-system
  values:
    replicaCount: 2

Is there a reason to only have 1 instance of appsmith running in the cluster?

Thank you

Are you on CE or EE?

We use the community edition?

Hi, in community edition we get a statefulSet and in order to scale the number of instances of appsmith you can do the following

kubectl scale statefulsets/<statefulset-name> -n <namespace> --replicas=<replicas_required>

autoscaling is not currently available in communityEdition.

Can you share the commands used and the behavior you are seeing because we couldn’t reproduce the behavior .

Your command is working. The cluster is configured with flux, so normally I don’t use kubectl directly. I use a helmRelease file base on your chart.
