How to replace users passwords with yaml variables?

Question

I am writing a MySQL script defining users and roles, but I don't want to upload the password to the repository. So I was guessing if I can replace those passwords with yaml variables.

USE test;

DROP USER IF EXISTS 'admin'@'127.0.0.1';
CREATE USER IF NOT EXISTS 'admin'@'127.0.0.1' IDENTIFIED BY 'password';

Changing the file to

USE test;

DROP USER IF EXISTS 'admin'@'{admin.host}';
CREATE USER IF NOT EXISTS 'admin'@'{admin.host}' IDENTIFIED BY '{admin.password}';

DROP USER IF EXISTS 'client'@'{client.host}';
CREATE USER IF NOT EXISTS 'client'@'{client.host}' IDENTIFIED BY '{client.password}';

admin:
  host: 127.0.0.1
  password: password
client:
  host: 0.0.0.0
  password: 123456

But I do not know how to implement this in MySQL. I was thinking in making a bash script to manually replace the variables, but not all of the team uses linux, so I would like to know if there is a MySQL way to do this.
