Downloads the module given by SOURCE into the PATH. The PATH defaults
to the working directory. PATH must be empty of any Terraform files.
Any conflicting non-Terraform files will be overwritten.
Initialize a new or existing Terraform environment by creating
initial files, loading any remote state, downloading modules, etc.
The module downloaded is a copy. If you're downloading a module from
Git, it will not preserve the Git history, it will only copy the
latest files.
This is the first command that should be run for any new or existing
Terraform configuration per machine. This sets up all the local data
necessary to run Terraform that is typically not comitted to version
control.
This command is always safe to run multiple times. Though subsequent runs
may give errors, this command will never blow away your environment or state.
Even so, if you have important information, please back it up prior to
running this command just in case.
If no arguments are given, the configuration in this working directory
is initialized.
If one or two arguments are given, the first is a SOURCE of a module to
download to the second argument PATH. After downloading the module to PATH,
the configuration will be initialized as if this command were called pointing
only to that PATH. PATH must be empty of any Terraform files. Any
conflicting non-Terraform files will be overwritten. The module download
is a copy. If you're downloading a module from Git, it will not preserve
Git history.
Options:
-backend=atlas Specifies the type of remote backend. If not
specified, local storage will be used.
-backend=true Configure the backend for this environment.
-backend-config="k=v" Specifies configuration for the remote storage
backend. This can be specified multiple times.
-backend-config=path A path to load additional configuration for the backend.
This is merged with what is in the configuration file.
-no-color If specified, output won't contain any color.
-get=true Download any modules for this configuration.

Usage: terraform remote config [options]
Configures Terraform to use a remote state server. This allows state
to be pulled down when necessary and then pushed to the server when
updated. In this mode, the state file does not need to be stored durably
since the remote server provides the durability.
Options:
-backend=Atlas Specifies the type of remote backend. Must be one
of Atlas, Consul, Etcd, GCS, HTTP, MAS, S3, or Swift.
Defaults to Atlas.
-backend-config="k=v" Specifies configuration for the remote storage
backend. This can be specified multiple times.
-backup=path Path to backup the existing state file before
modifying. Defaults to the "-state" path with
".backup" extension. Set to "-" to disable backup.
-disable Disables remote state management and migrates the state
to the -state path.
-pull=true If disabling, this controls if the remote state is
pulled before disabling. If enabling, this controls
if the remote state is pulled after enabling. This
defaults to true.
-state=path Path to read state. Defaults to "terraform.tfstate"
unless remote state is enabled.
-no-color If specified, output won't contain any color.
