Usage: terraform init [options] [DIR]
|
|
|
|
Initialize a new or existing Terraform working directory by creating
|
|
initial files, loading any remote state, downloading modules, etc.
|
|
|
|
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 committed to version
|
|
control.
|
|
|
|
This command is always safe to run multiple times. Though subsequent runs
|
|
may give errors, this command will never delete your configuration 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.
|
|
|
|
Options:
|
|
|
|
-backend=true Configure the backend for this configuration.
|
|
|
|
-backend-config=path This can be either a path to an HCL file with key/value
|
|
assignments (same format as terraform.tfvars) or a
|
|
'key=value' format. This is merged with what is in the
|
|
configuration file. This can be specified multiple
|
|
times. The backend type must be in the configuration
|
|
itself.
|
|
|
|
-force-copy Suppress prompts about copying state data. This is
|
|
equivalent to providing a "yes" to all confirmation
|
|
prompts.
|
|
|
|
-from-module=SOURCE Copy the contents of the given module into the target
|
|
directory before initialization.
|
|
|
|
-get=true Download any modules for this configuration.
|
|
|
|
-get-plugins=true Download any missing plugins for this configuration.
|
|
|
|
-input=true Ask for input if necessary. If false, will error if
|
|
input was required.
|
|
|
|
-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.
|
|
|
|
-plugin-dir Directory containing plugin binaries. This overrides all
|
|
default search paths for plugins, and prevents the
|
|
automatic installation of plugins. This flag can be used
|
|
multiple times.
|
|
|
|
-reconfigure Reconfigure the backend, ignoring any saved
|
|
configuration.
|
|
|
|
-upgrade=false If installing modules (-get) or plugins (-get-plugins),
|
|
ignore previously-downloaded objects and install the
|
|
latest version allowed within configured constraints.
|
|
|
|
-verify-plugins=true Verify the authenticity and integrity of automatically
|
|
downloaded plugins.
