How to build a public registry in AWS ECR (Elastic Container Registry)?

# Set up AWS CLI
aws configure

# Create a Public ECR Repository
aws ecr-public create-repository --repository-name redis --region <region>

# Authenticate Docker to ECR:
# public repo URI = public.ecr.aws/xxxx
aws ecr-public get-login-password --region <region> | docker login --username AWS --password-stdin <public repo URI>

# Pull image from DockerHub
# Need to specify platform to avoid error because docker will pull image version to match your current running OS
docker pull --platform=linux/amd64/v4 redis:latest

# Tag image
docker tag redis:latest public.ecr.aws/<account_id>/redis:latest

# Push image to ECR
docker push public.ecr.aws/<account_id>/redis:latest

# Verify image exists in ECR
aws ecr-public describe-images --repository-name redis --region <region>
