|
|
Pull the state from its location, upgrade the local copy, and output it
|
|
to stdout.
|
|
|
|
This command "pulls" the current state and outputs it to stdout.
|
|
As part of this process, Terraform will upgrade the state format of the
|
|
local copy to the current version.
|
|
|
|
The primary use of this is for state stored remotely. This command
|
|
will still work with local state but is less useful for this.
