Reset ArgoCD Application Finalizers

reset-argocd-application-finalizers.sh

# In switching Git repositories, I found you must delete the ArgoCD ApplicationSets and
# Applications in order to allow ArgoCD to recreate. However, deleting the resources can
# hang due to finalizers. Run the below script to reset the ArgoCD Application finalizers:

# get argocd applications by name, one per row
APPS=$(kubectl get -n ${NAMESPACE:-argocd} applications.argoproj.io -o=jsonpath='{range .items[*]}{.metadata.name}{"\t"}{"\n"}{end}')

# loop through and reset each application's finalizers
while read -r APP; do
  kubectl patch -n ${NAMESPACE:-argocd} applications.argoproj.io/$APP -p '{"metadata":{"finalizers":[]}}' --type=merge
done <<< $APPS

# verify sync/health status
kubectl get applications.argoproj.io -n argocd
