Build docker container for Mysql 8.0 fail

I need create a docker container for several projects tha use Mysql 8.0 with PHP 7.3

I like create it, because I need modify mysql startup configuration

For this I create

Dockerfile

FROM mysql:8.0

COPY mysqld_charset.cnf /etc/mysql/conf.d/mysqld_charset.cnf

ENV MYSQL_ROOT_PASSWORD="123456"

mysqld_charset.cnf

[mysqld]
default-authentication-plugin = mysql_native_password
collation-server = utf8mb4_general_ci
character-set-server = utf8mb4

License and readme files.

Execute 

$ docker build --no-cache -t mysql8_legacy_password .

The issue is in the run command.

docker run --name mysql8_legacy_password -it mysql:8.0

You are trying to start a container from mysql:8.0 image in which no env has been setup.

The last argument of the docker run command should be the image name. Since you have tagged your image as mysql8_legacy_password, this should work:

docker run --name container_name -it mysql8_legacy_password

docker run
