Usage: terraform refresh [options] [dir]
Update the state file of your infrastructure with metadata that matches
the physical resources they are tracking.
This will not modify your infrastructure, but it can modify your
state file to update metadata. This metadata might cause new changes
to occur when you generate a plan or call apply next.
Options:
-backup=path Path to backup the existing state file before
modifying. Defaults to the "-state-out" path with
".backup" extension. Set to "-" to disable backup.
-input=true Ask for input for variables if not directly set.
-lock=true Lock the state file when locking is supported.
-lock-timeout=0s Duration to retry a state lock.
-no-color If specified, output won't contain any color.
-state=path Path to read and save state (unless state-out
is specified). Defaults to "terraform.tfstate".
-state-out=path Path to write updated state file. By default, the
"-state" path will be used.
-target=resource Resource to target. Operation will be limited to this
resource and its dependencies. This flag can be used
multiple times.
-var 'foo=bar' Set a variable in the Terraform configuration. This
flag can be set multiple times.
-var-file=foo Set variables in the Terraform configuration from
a file. If "terraform.tfvars" is present, it will be
automatically loaded if this flag is not specified.
