# Pods in a specific namespace
kubectl get pods -n stiq
# All resources in a namespace
kubectl get all -n glamhub

Most applications follow a consistent multi-environment pattern:
Environment Namespace Suffix Domain Pattern Purpose
Production (none) app.domain.com Live traffic Development -dev dev-app.domain.com Active development Staging -staging staging-app.domain.com Pre-release validation
Example for STIQ:
stiq -> stiq.us, api.stiq.us, app.stiq.us, admin.stiq.usstiq-dev -> dev.stiq.us, dev-api.stiq.us, dev-app.stiq.us, dev-admin.stiq.usstiq-staging -> staging.stiq.us, staging-api.stiq.us, staging-app.stiq.us, staging-admin.stiq.us
