Bạn có nhiều project A, B, C thì thì nó chỉ khách nhau về variable thì chúng ta là sao?

Ở bài trước bạn có thể sư dụng theo kiểu module để manage được problem trên.
Ngoài ra chúng ta có 1 cách nữa đó là sử dụng workspace.

Giờ bạn nhìn ảnh trên.
Bạn có thể thấy ami được config theo dạng map.
-> nếu là Project A thì ami sẽ là ami-0eda…..
-> nếu là Project B thì ami sẽ là ami-0c2….

Mục đích là nếu chúng ta đang ở project A thì variable output của ami sẽ là ami-0eda….
chúng ta dùng hem lookup(var.<variable_name>, terraform.workspace)

Chuyển workspace:
terraform workspace select <workspace_name>
