Deploy will error if you change the serviceName to something other than the defaul.

It won't create the correct ECR Repository Name

You need to update 75_ecr.yml.j2 file and replace:

RepositoryName: "airflow-{{ ENVIRONMENT }}"

to something like:

RepositoryName: "{{ serviceName }}-{{ ENVIRONMENT }}-docker-ecr"
