|
## ArgoCD
|
|
|
|
|
- disable all auto-sync and "prune" features to prevent that eg. namespaces from previous apps get removed
|
2020-12-01 15:46:04 +00:00
|
|
|
- either remove auto-sync from old values.yaml and run deploy one last time, trigger kubezero sync !
|
|
|
|
|
- or disable manual via Argo UI starting with Kubezero app itself
