Building the Image locally

If building on an ARM mac, the image will build but will fail to deploy to Fargate with the following error: exec /usr/bin/dumb-init: exec format error

Instead, build the image via the below command, to build for the linux/amd64 platform.

DOCKER_DEFAULT_PLATFORM=linux/amd64 docker build --tag public.ecr.aws/uktrade/nginx-dbt-platform:<tag> .
