MySQL 8: caching_sha2_password not supported

[selim13]

Hey! Thanks for the report.
Yes, looks like MySQL 8 have changed their default auth method to caching_sha2_password. The problem is that Alpine linux (which this image is based on) contains only MariaDB version of mysql-client and they are not planning to support sha2 any time soon.

So to fix this, I either need to manually compile mysql-client from mysql 8 or switch to debian as a base for this image.

For now you can work around this issue by either creating a separate backup user with an old auth method or altering auth method for the root user.
See this stackoverflow thread for different solutions.

I will update the readme about current mysql 8 support status.

Ok, then I'll have to create my own docker image which support mysql 8. Thanks

I will leave this open, as I will eventually need to fix this.

Changed base image to debian:stretch-slim and now using official mysql-community-client-core package for mysqldump. This should solve problems with mysql 8 and hopefully won't introduce new ones.
