Argo CD Cleanup Script for Trend Micro Container Security

Overview

Argo CD cleanup script helps clean up Trend Micro Container Security resources in your Kubernetes cluster.

./argocd-cleanup.sh

Run this script in these scenarios:

  1. Stuck Argo CD Applications: When you've attempted to uninstall Trend Micro Container Security through Argo CD but the application is stuck in a "Deleting" state
  2. General Cleanup: Even if the application is not in a deleting state (i.e., after successful uninstallation), you want to ensure complete cleanup of all related resources

Resources Cleaned Up

The script handles deletion of Trend Micro Container Security resources including:

  • Argo CD application finalizers that may be preventing complete deletion
  • Trend Micro image pull secrets distributed across all namespaces
  • Trend Micro custom resource definitions (CRDs), specifically "workloadimages.cloudone.trendmicro.com"
  • Service accounts, cluster role bindings, and cluster roles of Trend Micro post-delete hooks
  • Cleanup Jobs in the Trend Micro system namespace

Prerequisites

  • kubectl command-line tool installed and configured to connect to your cluster
  • Appropriate permissions to delete cluster-wide resources

Script Usage

  1. Review and modify the variables at the top of the script if needed (default values mentioned below)
RELEASE_SERVICE=${RELEASE_SERVICE:-"Helm"}
CONTAINER_SECURITY_NAME=${CONTAINER_SECURITY_NAME:-"container-security"}
SOURCE_NAMESPACE=${SOURCE_NAMESPACE:-"trendmicro-system"}
ARGOCD_NAMESPACE="argocd"
  1. Make the script executable: chmod +x argocd-cleanup.sh
  2. Run the script: ./argocd-cleanup.sh
  3. Follow the prompts to confirm cleanup actions
