在Dockerfile中配置了ROOT密码为什么还是显示密码为空

Question

DockerFile

ENV MYSQL_ROOT_PASSWORD 123456
ENV MYSQL_USER user
ENV MYSQL_PASSWORD password
ENV MYSQL_ROOT_HOST %
ENV WORK_PATH=/usr/workdir

VOLUME C:\code\mysql\conf:/etc/mysql
VOLUME C:\code\mysql\logs:/logs
RUN mkdir -p $WORK_PATH
COPY schema.sql $WORK_PATH
COPY install.sh /docker-entrypoint-initdb.d

RUN chmod a+x /docker-entrypoint-initdb.d/install.sh

Warning

[Warning] root@localhost is created with an empty password ! Please consider switching off the --initialize-insecure option.

构建image语句

docker build -t mysql:tag /path

运行语句

docker run --name mysql_name -idt -p 3306:3306 mysql:tag

Answer 1

docker run -e MYSQL_ROOT_PASSWORD=123456类似这样才会生效
