# Helper script for providing a docker compose healthcheck to containers that are healthy with
# a non-200 status code.
#
# Usage:
#   ./healthcheck.sh url expected_response_code
#
# Example in docker compose expecting http://localhost:9999 to respond with a 401:
# ```
#   healthcheck:
#     test: ./healthcheck.sh http://localhost:9999 401
# ```

url=$1

status_code=$(curl --write-out %{http_code} --silent --output /dev/null $url)
if [[ "$status_code" -eq $expected_status_code ]]; then
