Ansible module to set values in a mysql table, or insert records. Useful for web-applications that store configurations in database. E.g. icingaweb2 requires the initial user to be inserted into the database. The install-wizard could do it, but with ansible you want to automate installation ;)
Listed at Ansible Galaxy Page as zauberpony.mysql-query.
Install via ansible-galaxy, ansible-galaxy install zauberpony.mysql-query
, or manually put the file mysql_query into your roles_path.
python bindings for mysql (just like the core mysql_* modules):
- MySQLdb (Python 2.x only)
- PyMySQL (Python 2.7 and python 3.x)

- hosts: all
roles:
- zauberpony.mysql-query
tasks:
- name: insert a row
mysql_query:
name: ansible-playbook-example
table: simple_table
login_host: ::1
login_user: root
login_password: password
identifiers:
id: 14
email: 'john@example.com'
values:
role: "admin"
department: 'IT'
defaults:
password: "secret"
last_login: 1469264933
Given a table simple_table
with columns (id, email, role, department, password, last_login), this example would:
- Look for a row where id = 14 and email = 'john@example.com'
- if the row does not exist: insert a row with id=14, email='john@example.com', role="admin", department="IT", password="secret", last_login=1469264933
- if the row does exist: check if the values (role, department) match the given values, if not: update
Thus:
- identifieres are being used to check for existence and to find a row
- defaults are being used as default values if the row is not present (i.e.: only used for insert)
- values are the state of the row that ansible ensures

Make sure you have a running mysql server (e.g.: use the docker-compose.yml-file) and update the connection-parameters if necessary.
Run via ansible-playbook -i demo.yml
(or even simpler ./demo.yml
) and undo (to start all over) with ansible-playbook -i reset.yml
.
After running ./demo.yml
, you can run ./checkmode-demo.yml -C
to test ansible's check mode.
Just run ./demo.yml
and ./checkmode-demo.yml
a few times with -C
and without -C
to get a feel for it.
