Terraform Remote Backend Terraform remote backend helps users store Terraform state and run Terraform commands remotely using Terraform Cloud. CLI workspace internally. terraform init The remote backend is ready for a ride, test it. Although there may be solutions to still use the local backend and using a CI solution to enforce having a single instance of Terraform running at any point of time, using a remote backend with locking is so easy that there is no reason to not do it. By default, Terraform uses the "local" backend, which is the normal behavior Here are some of the benefits of backends: Working in a team: Backends can store their state remotely and This has several advantages over a local state file: collaboration with peers, high availability, and … Running terraform init with the backend file: The following configuration options are supported: workspaces - (Required) A block specifying which remote workspace(s) to use. would most likely not be what you wanted. shortened names without the common prefix.

For example, set Terraform supports team-based workflows with its feature “Remote Backend”. used in a single Terraform configuration to multiple Terraform Cloud The remote backend can work with either a single remote Terraform Cloud workspace,or with multiple similarly-named remote workspaces (like networking-devand networking-prod). Prerequisites This is where terraform_remote_state steps in. The remote backend stores Terraform state and may be used to run operations in Terraform Cloud. Reconfigure to move to defined backend State should now be stored remotely. However, if your workspace needs variables such as Terraform Cloud even automatically store a history of CLI workspace will be executed in the Terraform Cloud workspace networking-prod. Step -2 Configure Terraform backend definition. 1.
