# Command: refresh
|
|
|
|
The `terraform refresh` command is used to reconcile the state Terraform
|
|
knows about (via its state file) with the real-world infrastructure.
|
|
This can be used to detect any drift from the last-known state, and to
|
|
update the state file.
|
|
|
|
This does not modify infrastructure, but does modify the state file.
|
|
If the state is changed, this may cause changes to occur during the next
|
|
plan or apply.
|
|
|
|
## Usage
|
|
|
|
Usage: `terraform refresh [options] [dir]`
|
|
|
|
By default, `refresh` requires no flags and looks in the current directory
|
|
for the configuration and state file to refresh.
|
|
|
|
The command-line flags are all optional. The list of available flags are:
|
|
|
|
* `-backup=path` - Path to the backup file. Defaults to `-state-out` with
|
|
the ".backup" extension. Disabled by setting to "-".
|
|
|
|
* `-no-color` - Disables output with coloring
|
|
|
|
* `-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 write the state file to. Defaults to "terraform.tfstate".
|
|
Ignored when [remote state](/docs/state/remote.html) is used.
|
|
|
|
* `-state-out=path` - Path to write updated state file. By default, the
|
|
`-state` path will be used. Ignored when
|
|
[remote state](/docs/state/remote.html) is used.
|
|
|
|
* `-target=resource` - A [Resource
|
|
Address](/docs/internals/resource-addressing.html) 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. Variable values are interpreted as
|
|
[HCL](/docs/configuration/syntax.html#HCL), so list and map values can be
|
|
specified via this flag.
|
|
|
|
* `-var-file=foo` - Set variables in the Terraform configuration from
|
|
a [variable file](/docs/configuration/variables.html#variable-files). If
|
|
"terraform.tfvars" is present, it will be automatically loaded first. Any
|
|
files specified by `-var-file` override any values in a "terraform.tfvars".
|
|
This flag can be used multiple times.
