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.
