# Linux is the core. Make a safe playground:
$ mkdir -p ~/codeku && cd ~/codeku
$ grep -i PRETTY_NAME /etc/os-release # show distro
$ echo 'alias k=kubectl' >> ~/.bashrc && source ~/.bashrc
# alias ready → use `k get pods` later

$ docker --version # Docker ready?
$ kubectl version --client --short # kubectl ready?
$ docker run --rm hello-world
$ k get nodes # if K8s configured

$ aws sts get-caller-identity   # AWS whoami
$ az account show               # Azure whoami
$ gcloud config list            # GCP context
$ curl -fsS http://localhost:9090/-/ready  # Prometheus ready?
# Grafana default → http://localhost:3000

$ terraform -version  # Terraform check
$ ansible --version   # Ansible check

# Quickstart scratch files:
$ echo 'provider "aws" {}' > main.tf
$ echo '- hosts: localhost\n  tasks:\n   - debug: msg="Hello from Ansible"' > play.yml
# IaC playground ready!
