Terraform state

Question 1

What is a backend?

Answer 1

A “backend” in Terraform determines how state is loaded and how an operation such as apply is executed.

Question 2

Local backend

Answer 2

The local backend stores state on the local filesystem, locks that state using system APIs, and performs operations locally.

Question 3

Default path for local backend

Answer 3

terraform.tfstate

Question 4

state locking

Answer 4

If supported by your backend, Terraform will lock your state for all operations that could write state.

Question 5

remote backends

Answer 5

Remote backends allow Terraform to use a shared storage space for state data, so any member of your team can use Terraform to manage the same infrastructure.

Question 6

refresh

Answer 6

The terraform refresh command is used to reconcile the state Terraform knows about (via its state file) with the real-world infrastructure.
