Dockerコンテナにmysql 5.7をインストールしようとすると、次のエラーが発生します。私はドッカーとコンテナを初めて使用します。

Step 16/23 : RUN apt-get install mysql-server-5.7

 Package mysql-server-5.7 is not available, but is referred to by another package.
 This may mean that the package is missing, has been obsoleted, or
 is only available from another source
 However the following packages replace it:
   mariadb-server-10.3
 E: Package 'mysql-server-5.7' has no installation candidate
 Service 'web' failed to build: The command '/bin/sh -c apt-get install mysql-server-5.7' returned a non-zero code: 100
