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.

suggested below.

This may result from mistyping the provider name, or the given provider may

provider %[1]q block in configuration. Child modules may also apply
|
|
provider version constraints. To view the provider versions requested by each
|
|
module in the current configuration, run "terraform providers".

To proceed, the version constraints for this provider must be relaxed by

Consult the documentation for this provider for more information on

Terraform analyses the configuration and state and automatically downloads

plugins for the providers used. However, when attempting to download this

plugin an unexpected error occured.

This may be caused if for some reason Terraform is unable to reach the

plugin repository. The repository may be unreachable if access is blocked

by a firewall.

Terraform can automatically download and install plugins to meet the given

you may manually install plugins by downloading a suitable distribution package
