mysql:5.6 docker image is executing `/docker-entrypoint-initdb.d` on every `nerdctl compose down; nerdctl compose up` how to limit it to first build?

Question

As mentioned above the database is being initialized on every nerdctl compose down; nerdctl compose up? We are trying to spin a test database with some seed data for local testing.

The following is the Dockerfile definition

FROM mysql:5.6

ENV MYSQL_DATABASE some_name
ENV MYSQL_ALLOW_EMPTY_PASSWORD 1
COPY mysql-bootstrap/*.sql* /docker-entrypoint-initdb.d/

EXPOSE 3306

The following is the docker-compose.yml file definition.

version: "3.9"
services:
  database:
    platform: linux/x86_64
    build: database
    ports:
      - "3306:3306"

I've not mounted any volume as I wanted to use docker's internal volume management as mentioned in Where to Store Data section of https://hub.docker.com/_/mysql

I'm using nerdctl provided by rancherdesktop on macos
