What tools, besides Helm, have you used for deployment automation?

In addition to Helm, the following tools are often used for deployment automation:

• Ansible — for configuration management and automating application deployment on servers.
• Terraform — for managing infrastructure as code, especially in cloud environments.
• Jenkins or other CI/CD systems (GitLab CI, GitHub Actions) — for automating build, testing, and deployment.
• Kustomize — for managing Kubernetes configurations without templates.
• Argo CD — for GitOps approach to deployment in Kubernetes.

For example, with Ansible, you can describe a playbook that automatically deploys an application on a server:

- hosts: webservers
  tasks:
    - name: Clone repository
      git:
        repo: 'https://github.com/example/app.git'
        dest: /var/www/app
    - name: Start service
      systemd:
        name: app
        state: restarted

The choice of tool depends on the infrastructure and project requirements.
