Lately I am working on automating my website creation so that if I want to change my hosting provider. The other thought is to host my site locally on my kubernetes cluster which I am planing to implement in my home. I created an Ansible playbook to automate my WordPress website installation as this a small project with out complexity. This is a kind of backup strategy for the site so I will have latest backup of linuxnix.com site. After almost 3 years later I started using Ansible for this project. I felt Chef and puppet is not that suitable for this.

I written couple of roles for

  1. WordPress software installation
  2. MySQL software installation
  3. Nginx software installation etc.

When I executed my playbook containing these roles I come across below weird error.

root@linuxnix:~# ansible-playbook -i wordpress-setup/hosts wordpress-setup/wordpress-setup.yml

Error:

ERROR! unexpected parameter type in action: <type 'bool'>

The error appears to be in '/root/wordpress-setup/roles/mysql/tasks/main.yml': line 2, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
- name: Install MySQL software
^ here

Initially I thought it was a linting issue(A kind of file format issue) within in my mysql tasks as it show error above. But after carefully observing I come to know the actual error was with unexpected parameter not with any linting issue from the first line in above error message.

My SQL role file contains:

---
- name: Install MySQL software
apt: name={{ item }} state=present
sudo: yes
with_items:
- mysql-server
- php-mysql
- php
- python-mysqldb
- php-curl
- php-gd
- php-intl
- php-mbstring
- php-soap
- php-xml
- php-xmlrpc
- php-zip
- php-fpm
- php-pear
- php-dev

- name: Start SQL and php-fpm services
service: name={{ item }} state=started
with_items:
- mysql
- php7.2-fpm

After digging for some time I cam across sudo keyword is no more supported from Anisble 2.9. So I have to change my above sudo command to become:. After doing this my Anisble cookbook ran successfully and I am able to create my website.

The new role with become keyword is as below.

---
- name: Install MySQL software
apt: name={{ item }} state=present
become: yes
with_items:
- mysql-server
- php-mysql
- php
- python-mysqldb
- php-curl
- php-gd
- php-intl
- php-mbstring
- php-soap
- php-xml
- php-xmlrpc
- php-zip
- php-fpm
- php-pear
- php-dev

- name: Start SQL and php-fpm services
service: name={{ item }} state=started
with_items:
- mysql
- php7.2-fpm

After updating this, I am able to automate whole website creation.
