▶ todo 테이블

[vagrant@docker1 mysql]$ cat todo.sql
USE todo;
CREATE TABLE tasks (
        id int not null auto_increment,
        task varchar(255),
        primary  key(id)
);

 

● docker-entrypoint-initdb.d 에 들어가면 db 가 만들어진다

[vagrant@docker1 mysql]$ cat Dockerfile
FROM mysql:5.7
ENV MYSQL_ROOT_PASSWORD=mypass MYSQL_DATABASE=todo
ADD ./todo.sql /docker-entrypoint-initdb.d/
EXPOSE 3306

 

 

◎ docker-entrypoint.sh 라는 셀 스크립트가 있다

>> 셀 스크립트에서 docker-entrypoint-initdb 검색

[vagrant@docker1 mysql]$ docker exec -it mydb /bin/bash
bash-4.2# find / -name docker-entrypoint.sh
/usr/local/bin/docker-entrypoint.sh

 

# 참조되어 todo.sql 이 들어가면서 테이블이 생성되는건가...;;

bash-4.2# grep -A 10 "docker-entrypoint" /usr/local/bin/docker-entrypoint.sh
                        ls /docker-entrypoint-initdb.d/ > /dev/null

                        docker_init_database_dir "$@"

                        mysql_note "Starting temporary server"
                        docker_temp_server_start "$@"
                        mysql_note "Temporary server started."

                        docker_temp_server_stop
                        mysql_note "Temporary server stopped"

                        echo
                        mysql_note "MySQL init process done. Ready for start up."

▩ db 와 연동이 안되어있다

>> 글자가 들어가지 않는다

 

 

 

● index.php 파일을 바꿔준다

 

 

>> 제대로 작동한다
