Do you have practical experience using Docker, Kubernetes, or Ansible in previous projects?

Yes, I have practical experience using all three tools:

• Docker — used for containerizing applications, creating isolated development environments, and deployment. For example, I wrote Dockerfiles for Python applications to package dependencies and run services in containers.

• Kubernetes — applied for orchestrating containers in a production environment. I configured manifests (Deployment, Service, ConfigMap), managed scaling and updates of applications.

• Ansible — used for automating server setup and application deployment. I wrote playbooks for installing dependencies, copying files, and starting services.

An example of a simple Ansible playbook for installing Python packages:

- hosts: webservers
  tasks:
    - name: Install pip
      apt:
        name: python3-pip
        state: present
    - name: Install dependencies from requirements.txt
      pip:
        requirements: /path/to/requirements.txt

These tools help automate and simplify development and operations processes.
