Пример сборки докер образа MySQL 8 с базой данных, с дамп файла.
Содержимое:
- Dockerfile
- mysqld.cnf
- dump.sql
Dockerfile:
FROM mysql:8
RUN apt update && \
apt install -y psmisc
ENV MYSQL_ROOT_PASSWORD MyRootPassword
ENV MYSQL_DATABASE artem_db
ENV MYSQL_USER database_user
ENV MYSQL_PASSWORD MyUserPassword
COPY dump.sql /docker-entrypoint-initdb.d/db.sql
COPY my.cnf /etc/mysql/my.cnf
RUN /entrypoint.sh mysqld &; sleep 30 && killall mysqld
RUN rm /docker-entrypoint-initdb.d/db.sql
Обратите внимание, что теперь переменные «MYSQL_USER» и «MYSQL_PASSWORD» задаются в Dockerfile
В файле «my.cnf» необходимо заменить только дефолтный путь хранения файлов MySQL
mysqld.cnf

Путь в этой строке:
datadir = /var/lib/mysql
На другой путь:
datadir = /var/lib/mysql_artem_service
И собираем образ:
docker build -t artem_db .
