Core application changes

Post-upgrade actions

After upgrading to v4.13.0, you may need to perform a few additional steps depending on the features and apps that are used on your App Platform deployment.

• If you are using the Auto Image Updater feature for any workloads, there are some changes to file locations within your local Gitea repositories. See Change repository when using Auto Image Updater for a workload .
• If you are using any of the apps that have been removed in this release and want to remove and clean up their resources, see Clean up resources for apps that have been removed .

Change repository when using Auto Image Updater for a workload

Users that are leveraging a workload’s Auto Image Updater feature may need to transfer a file between Gitea repositories. For each workload, move and rename the original file below from the otomi/charts Gitea repository to a new file in the otomi/values Gitea repository.

• Old file (in otomi/charts): <chartName>/.argocd-source-<teamId>-<workloadName>.yaml
• New file (in otomi/values ): env/teams/<teamId>/workloadValues/<workloadName>.managed.yaml

Clean up resources for apps that have been removed

A few deprecated apps have been removed in this release and are no longer supported. App Platform doesn’t automatically clean up all resources for these apps as some users may continue using them until they are able to transition to other apps. If you do wish to remove these apps and their associated resources, use the commands below.

Falco

• kubectl delete application falco-falco -n argocd
• kubectl delete application falco-falco-exporter -n argocd
• kubectl delete namespace falco

HTTPbin

• kubectl delete namespace httpbin

Jaeger

• kubectl delete application jaeger-operator-jaeger-operator -n argocd
• kubectl delete namespace jaeger
• kubectl delete namespace jaeger-operator
• kubectl get crd | grep -i jaeger (finds all jaeger crds)
• kubectl delete crd jaegers.jaegertracing.io

Kiali

• kubectl delete application kiali-operator-kiali-operator -n argocd
• kubectl delete application kiali-kiali-operator-artifacts -n argocd
• kubectl delete namespace kiali
• kubectl delete namespace kiali-operator
• kubectl get crd | grep -i kiali (finds all Kiali crds)
• kubectl delete crd kialis.kiali.io

Kured\

🚧

Be careful when removing resources for kured as some live in the kube-system namespace. To prevent unintended deletions, delete resources in that namespace by label.

• kubectl delete application kube-system-kured -n argocd
• kubectl delete all -n kube-system -l app.kubernetes.io/name=kured

Velero

• kubectl delete namespace velero
