Value not written to custom.cnf when 0

[ghost]

Hi,

When the custom.cnf file is generated, if a key-value mapping has a numerical value greater than 0 then {{ key }}={{ value }} is written to file, else only {{ key }} is written.

mariadb_custom_cnf:
mysqld:
server_id: '{{ groups[mariadb_servers].index(inventory_hostname) | int + 1 }}'
log_bin: 'mysqld-bin'
replicate-same-server-id: 0
replicate-do-db: 'testdb'

Generated custom.cnf file
[mysqld]
server_id=1
log_bin=mysqld-bin
replicate-same-server-id (expected : replicate-same-server-id=0, as per the MariaDB documentation)
replicate-do-db=testdb

Would it be possible to look into this "issue" for a future release?

Thank you in advance.

Kinds regards,

It's best to consider all values, even numerical ones, as strings:

mariadb_custom_cnf:
  mysqld:
    server_id: '{{ groups[mariadb_servers].index(inventory_hostname) | int + 1 }}'
    log_bin: 'mysqld-bin'
    replicate-same-server-id: "0"  # Enter numbers as strings
    replicate-do-db: 'testdb'

I'll update the documentation to warn users for this.
