エラーメッセージでググったらこちらの記事がヒット。

この記事を参考に修正したところ、今度は違うエラーが。

$ docker logs 2f9127b2dd11

再度エラーメッセージでググって解決方法を探したところ、docker-compose.ymlをいじれば良さそう。

    mysql:
      build:
        context: ./mysql
        args:
          - MYSQL_VERSION=${MYSQL_VERSION}
      environment:
        - MYSQL_DATABASE=${MYSQL_DATABASE}
        - MYSQL_USER=${MYSQL_USER}
        - MYSQL_PASSWORD=${MYSQL_PASSWORD}
        - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
        - TZ=${WORKSPACE_TIMEZONE}
      volumes:
        - ${DATA_PATH_HOST}/mysql:/var/lib/mysql
        - ${MYSQL_ENTRYPOINT_INITDB}:/docker-entrypoint-initdb.d
      ports:
        - "${MYSQL_PORT}:3306"
      networks:
        - backend
      command: --innodb-use-native-aio=0 #コイツを追加！！！！！

一番最後のを追記したら無事動いた。
