Playbook Ansible để triển khai CaptchaAI Worker

Cơ sở hạ tầng cung cấp Terraform; Ansible cấu hình nó. Sử dụng sổ tay Ansible để triển khai các trình xử lý CAPTCHA trên nhóm máy chủ của bạn, đẩy các thay đổi về cấu hình và chạy các bản cập nhật luân phiên mà không có thời gian ngừng hoạt động.

Câu hỏi thường gặp

Làm cách nào để lưu trữ khóa API một cách an toàn?

Sử dụng Ansible Vault: ansible-vault encrypt_string 'your-api-key' --name 'captchaai_api_key'. Tham chiếu biến được mã hóa trong kho hoặc nhóm nhóm của bạn.

Tôi có thể sử dụng Ansible với vùng chứa Docker không?

Vâng. Thay thế các tác vụ systemd bằng mô-đun community.docker.docker_container. Ansible quản lý vòng đời của container thay vì dịch vụ systemd.

Ansible so sánh với Terraform như thế nào?

Terraform cung cấp cơ sở hạ tầng (tạo máy chủ, mạng). Ansible cấu hình máy chủ (cài đặt phần mềm, triển khai mã). Sử dụng cả hai cùng nhau — Terraform tạo nhóm, Ansible định cấu hình nhóm đó.
