Issue with pipeline service mysql and ansible connection

(I'm sorry I couldnt work out how to pase code into the code block, and retain its formatting. Ive cleaned up where needed to make readable)

Basically, I can not get ansible to connect and create a user. Tried a few different options, but I always get back to some variation of:

unable to connect to database, check login_user and login_password are correct or /root/.my.cnf has the credentials.
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'


image: mysql:5.7
MYSQL_USER: 'test_user'
MYSQL_PASSWORD: 'test_user_password'

- parallel:
- step:
name: test
- mysql

- apt-get update && apt-get install -y mysql-client
- mysql -h -u test_user -ptest_user_password -e "SHOW DATABASES"
- ansible-playbook ci.yml -i hosts --connection=local


The SHOW DATABASES line works.

However, when the ansible playbook gets to my task:

- name: add dev user to database
  name: '{{backend_database.user}}'
  password: '{{backend_database.pass}}'
  login_password: 'test_user_password'
  login_user: 'test_user'
  host: '{{backend_database.address}}'
  priv: '*.*:ALL'
  state: present
become: true

 I always get the error above.

I've tried so many combinations of things and always fails here.
Includingm adding to the ansible task:

login_unix_socket: '/var/run/mysqld/mysqld.sock'
login_unix_socket: /var/lib/mysql/mysql.sock

Any pointers or advice on things to look into would be greatly appreciated. I'm very confused at what I'm missing here.

To be clear, this works locally on my vagrant box.

I've seen this similar error before when there is no mysql-server running, but I assume the working SHOW DATABASES proves there is a mysql server running?

Cheers for any help.

Ok, I missed one variable from the ansible docks that helped here:

login_host: default is localhost

- name: add dev user to database
name: '{{backend_database.user}}'
password: '{{backend_database.pass}}'
login_host: '{{backend_database.address}}'
host: '{{backend_database.address}}'
priv: '*.*:ALL'
state: present
become: true


Hopefully this helps others coming up against the socket error.
