Answer 1

If you are trying to connect to a MySQL server from a text-based MySQL client from another computer (be it Docker or not)

Most answers here involve connecting from a desktop client, or ask you to switch to an older authentication method. If you're connecting it with the MySQL client (text-based), I made it work with a Debian Buster in a Docker container.

Say you have the apt system and wget set up, do the following:

1. sudo apt-get update
2. sudo apt-get install lsb-release -y
3. Download a Debian package which update apt sources for you from the MySQL web site.
4. sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb and select the options you want. In my case I only need MySQL Tools & Connectors to be enabled.
5. sudo apt-get update
6. sudo apt-get install mysql-client -y
7. Done. You can now run the new MySQL client and connect with the new authentication method.
