Registry
ELI5 — The Vibe Check
A registry is a storage place for container images — like an app store but for Docker images. When you build an image, you push it to a registry. When Kubernetes needs to run your app, it pulls the image from the registry. Docker Hub is the public one, but most companies use private registries.
Real Talk
A container registry is a repository for storing and distributing container images. Public registries include Docker Hub and GitHub Container Registry. Private registries include AWS ECR, GCP Artifact Registry, and Azure Container Registry. Images are identified by registry URL, name, and tag.
