Getting Started

Prerequisites

• 
  Docker: Required for image building and container operations


• 
  Kubernetes Cluster: Access to a cluster with configured kubectl


• 
  RBAC Permissions: Appropriate permissions for resource deployment and execution

Building the Docker Image

git clone https://github.com/narmidm/K8sToolbox.git

cd K8sToolbox

docker build -t k8stoolbox:latest -f docker/Dockerfile .

Deployment Options

Standalone Pod Deployment

For targeted debugging sessions:

kubectl apply -f https://raw.githubusercontent.com/narmidm/K8sToolbox/master/manifests/debug-pod.yaml

DaemonSet Deployment

For cluster-wide availability:

kubectl apply -f https://raw.githubusercontent.com/narmidm/K8sToolbox/master/manifests/debug-daemon.yaml
