ArgoCd don't sync

Check

The sync is performed by the argocd-application-controller.

Check that the pod is running.

Possible Solutions

By default, during the sync, the ArgoCD controller may see some memory peak

Increase Memory

Therefore, we set a default limit around 400Mi. The more you add manifests, the more memory it will need.

In your cluster values file, increase the memory value

Example:

argocd:
  enabled: true
  hostname: 'argocd-xxx.sslip.io'
  components:
    argocd_application_controller:
      resources:
        # increase this value
        memory: '450Mi'

Decrease History

• On replica set

# nonk8s
apiVersion: apps/v1
kind: Deployment
metadata:
  name: xxxx
spec:
  # Keep only 3 old ReplicaSets (default is 10)
  revisionHistoryLimit: 3

• On cron job (not much impact)

# nonk8s
apiVersion: batch/v1
kind: CronJob
spec:
  # how many completed (successful) Jobs to keep (default: 3) - 0, none
  successfulJobsHistoryLimit: 0
  # how many failed Jobs to keep (default: 1)
  failedJobsHistoryLimit: 1
