Supported Registries for docker-to-iac module

docker-to-iac supports multiple Docker image registries. Below you'll find details about supported registries and examples of how they are handled.

Docker Hub Registry

Docker Hub is the default and most common registry for Docker images.

Official Images

Docker Hub official images are maintained by Docker and don't include a username/organization prefix.

Docker Compose Example:

services: 
  db: 
    image: redis:latest

Translated Image URL:

docker.io/library/redis:latest

User/Organization Images

Docker Hub images that belong to specific users or organizations include the username/organization as prefix.

Docker Compose Example:

services: 
  app: 
    image: nginx/nginx-prometheus-exporter:0.10.0

Translated Image URL:

docker.io/nginx/nginx-prometheus-exporter:0.10.0

GitHub Container Registry (GHCR)

GitHub Container Registry is GitHub's container registry service that allows you to host and manage Docker container images.

Docker Compose Example:

services:
  monitor: 
    image: ghcr.io/dgtlmoon/changedetection.io

Translated Image URL:

ghcr.io/dgtlmoon/changedetection.io

Registry URL Formats

Here's how different registry types are handled:

Notes

• If no tag is specified, latest is used as the default tag
• The module preserves the original registry URL format for custom registries
• SHA256 digests are supported for all registry types
