Lightsail is a good home for a single small container: flat pricing, bandwidth included, and none of the VPC/security-group ceremony of EC2. The one rough edge is pulling a private image from Amazon ECR, because a standard Lightsail instance can't authenticate to ECR the way EC2 can. This post walks the whole path.

The pipeline we're building:

docker build ──push──> ECR (private repo) ──pull──> Lightsail instance ──run──> container
