MYSQL docker file - docker

Question

I have a mysql docker file as follows:
FROM mysql:latest
ENV MYSQL_ROOT_PASSWORD password
ENV MYSQL_DATABASE database
ENV MYSQL_USER root
ENV MYSQL_PASSWORD mysql007
ENV COMPOSE_CONVERT_WINDOWS_PATHS 1
COPY init.sql /docker-entrypoint-initdb.d/
RUN chmod a+x /docker-entrypoint-initdb.d/init.sql && chown root:root /docker-entrypoint-initdb.d/init.sql
EXPOSE 3306
CMD ["mysqld"]
I build the file using the following command on docker terminal:
docker build --build-arg http_proxy=<value> --build-arg https_proxy=<value> -f mySQL_Dockerfile -t mysql .
Whenever I run the docker file it gives me the following log and exits:

ERROR 1396 (HY000) at line 1: Operation CREATE USER failed for 'root'#'%'
Any idea what the problem could be? It says the root user creation failed and exits!
Thanks.

Answer 1

Turns out the suggested answer works but on a different version of the mysql image. It doesn't seem to be working for mysql:latest. I changed to mysql:5.7 and the suggested solution worked just fine.

Answer 2

I encountered the same problem, the fix is easy, If you want to use root as your user, just set MYSQL_ROOT_PASSWORD, don't set MYSQL_PASSWORD, checkout this post.
