From e25b0bd62cf2741e783b1fd4e88bbad248a1be70 Mon Sep 17 00:00:00 2001 From: Anderson Nogueira Date: Wed, 27 Aug 2025 12:32:09 +0200 Subject: [PATCH 01/23] Add comprehensive OpenShift cluster destroyer script - Safely destroys OpenShift clusters on AWS with all associated resources - Supports multiple destruction methods: openshift-install and manual AWS cleanup - Handles orphaned clusters without state files - Includes dry-run mode for preview without deletion - Comprehensive resource counting and detailed listing - Route53 DNS and S3 state cleanup - Safety features: confirmation prompts, detailed logging - Auto-detects infrastructure ID from cluster name - Properly counts nested VPC resources (subnets, security groups, etc.) --- scripts/destroy-openshift-cluster.sh | 1042 ++++++++++++++++++++++++++ 1 file changed, 1042 insertions(+) create mode 100755 scripts/destroy-openshift-cluster.sh diff --git a/scripts/destroy-openshift-cluster.sh b/scripts/destroy-openshift-cluster.sh new file mode 100755 index 0000000000..5c6149d9d5 --- /dev/null +++ b/scripts/destroy-openshift-cluster.sh @@ -0,0 +1,1042 @@ +#!/bin/bash +# +# OpenShift Cluster Destroyer Script +# +# This script can destroy OpenShift clusters in various states: +# - Properly installed clusters with metadata.json +# - Orphaned clusters without state files +# - Partially created clusters that failed during installation +# +# Usage: ./destroy-openshift-cluster.sh [OPTIONS] +# +# Required parameters (one of): +# --cluster-name NAME Base cluster name (will auto-detect infra-id) +# --infra-id ID Infrastructure ID (e.g., cluster-name-xxxxx) +# --metadata-file PATH Path to metadata.json file +# +# Optional parameters: +# --region REGION AWS region (default: us-east-2) +# --profile PROFILE AWS profile (default: percona-dev-admin) +# --base-domain DOMAIN Base domain for Route53 (default: cd.percona.com) +# --dry-run Show what would be deleted without actually deleting +# --force Skip confirmation prompts +# --verbose Enable verbose output +# --s3-bucket BUCKET S3 bucket for state files (auto-detected if not provided) +# --help Show this help message + +set -euo pipefail + +# Default values +AWS_REGION="${AWS_REGION:-us-east-2}" +AWS_PROFILE="${AWS_PROFILE:-percona-dev-admin}" +BASE_DOMAIN="${BASE_DOMAIN:-cd.percona.com}" +DRY_RUN=false +FORCE=false +VERBOSE=false +CLUSTER_NAME="" +INFRA_ID="" +METADATA_FILE="" +S3_BUCKET="" +LOG_FILE="/tmp/openshift-destroy-$(date +%Y%m%d-%H%M%S).log" + +# Color codes for output +RED='\033[0;31m' +GREEN='\033[0;32m' +YELLOW='\033[1;33m' +BLUE='\033[0;34m' +BOLD='\033[1m' +NC='\033[0m' # No Color + +# Logging functions +log() { + echo -e "${1}" | tee -a "$LOG_FILE" +} + +log_info() { + log "${BLUE}[INFO]${NC} ${1}" +} + +log_success() { + log "${GREEN}[SUCCESS]${NC} ${1}" +} + +log_warning() { + log "${YELLOW}[WARNING]${NC} ${1}" +} + +log_error() { + log "${RED}[ERROR]${NC} ${1}" +} + +log_debug() { + if [[ "$VERBOSE" == "true" ]];
