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.

`
const errProviderVersionsUnsuitable = `
[reset][bold][red]No provider %[1]q plugins meet the constraint %[2]q.[reset][red]
The version constraint is derived from the "version" argument within the
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
either adjusting or removing the "version" argument in the provider blocks
throughout the configuration.
`
const errProviderIncompatible = `
[reset][bold][red]No available provider %[1]q plugins are compatible with this Terraform version.[reset][red]
From time to time, new Terraform major releases can change the requirements for
plugins such that older plugins become incompatible.
Terraform checked all of the plugin versions matching the given constraint:
%[2]s
Unfortunately, none of the suitable versions are compatible with this version
of Terraform. If you have recently upgraded Terraform, it may be necessary to
move to a newer major release of this provider. Alternatively, if you are
attempting to upgrade the provider to a new major version you may need to
also upgrade Terraform to support the new version.
Consult the documentation for this provider for more information on
compatibility between provider versions and Terraform versions.
`
const errProviderInstallError = `
[reset][bold][red]Error installing provider %[1]q: %[2]s.[reset][red]
Terraform analyses the configuration and state and automatically downloads
plugins for the providers used. However, when attempting to download this
plugin an unexpected error occurred.
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.
If automatic installation is not possible or desirable in your environment,
you may alternatively manually install plugins by downloading a suitable
distribution package and placing the plugin's executable file in the
following directory:
%[3]s
`
const errMissingProvidersNoInstall = `
[reset][bold][red]Missing required providers.[reset][red]
The following provider constraints are not met by the currently-installed
provider plugins:
%[1]s
Terraform can automatically download and install plugins to meet the given
constraints, but this step was skipped due to the use of -get-plugins=false
and/or -plugin-dir on the command line.
If automatic installation is not possible or desirable in your environment,
you may manually install plugins by downloading a suitable distribution package
and placing the plugin's executable file in one of the directories given in
by -plugin-dir on the command line, or in the following directory if custom
plugin directories are not set:
%[2]s
`
const errChecksumVerification = `
[reset][bold][red]Error verifying checksum for provider %[1]q[reset][red]
The checksum for provider distribution from the Terraform Registry
did not match the source. This may mean that the distributed files
were changed after this version was released to the Registry.
`
const errSignatureVerification = `
[reset][bold][red]Error:[reset][bold] Untrusted signing key for provider %[1]q[reset]
This provider package is not signed with the HashiCorp signing key, and is
therefore incompatible with Terraform v%[2]s.
A later version of Terraform may have introduced other signing keys that would
accept this provider. Alternatively, an earlier version of this provider may
be compatible with Terraform v%[2]s.
