What is your experience with Ansible?

More than three years of active use of Ansible for automation of deployment, configuration management, and application and infrastructure orchestration.

Main areas of application:

• Configuration management: Maintaining a consistent state of servers and services.
• Application deployment: Automating the build, delivery, and installation process of applications.
• Orchestration: Managing the sequence of task execution across multiple servers.
• Automation of administrative tasks: Backup, update, monitoring.

Worked with various Ansible modules, including:

• apt, yum, dnf: Package management.
• service: Service management.
• copy, template: File management.
• command, shell: Command execution.
• uri: API interaction.
• Modules for working with Docker, Kubernetes, cloud providers (AWS, GCP).

Use Ansible Vault for secret management.

Experience in writing and debugging playbooks of various complexities, including roles, include/import, handlers, vars, facts, loops, conditionals.

Applied Ansible for:

• Setting up and configuring web servers (Nginx, Apache).
• Deployment of microservices and monoliths.
• Managing databases (PostgreSQL, MySQL).
• Configuring monitoring and logging.

Example of a simple Ansible role:

# roles/my_webapp/tasks/main.yml
- name: Install dependencies
  apt:
    name: "{{ item }}"
    state: present
  loop:
    - python3
    - python3-pip

- name: Copy application files
  copy:
    src: files/app/
    dest: /opt/my_webapp/

- name: Install python packages
  pip:
    requirements: /opt/my_webapp/requirements.txt

- name: Configure systemd service
  template:
    src: templates/my_webapp.service.j2
    dest: /etc/systemd/system/my_webapp.service
  notify: restart my_webapp_service

# roles/my_webapp/handlers/main.yml
- name: restart my_webapp_service
  systemd:
    name: my_webapp
    state: restarted
