push

#!/bin/bash

# Pushes built images to AWS' ECR (Elastic Container Registry).
#
# Requires aws-cli, jq, and docker.

#
# NOTE: While running this script, if
#
#    (1) aws-cli says that it doesn't recognize `--no-include-email`
# or (2) docker requires an email (via `-e`)
#
# then update both aws-cli and docker and try running this again.
