cli: allow disabling "next steps" message in terraform plan In #15884 we adjusted the plan output to give an explicit command to run to apply a plan, whereas before this command was just alluded to in the prose. Since releasing that, we've got good feedback that it's confusing to include such instructions when Terraform is running in a workflow automation tool, because such tools usually abstract away exactly what commands are run and require users to take different actions to proceed through the workflow. To accommodate such environments while retaining helpful messages for normal CLI usage, here we introduce a new environment variable TF_IN_AUTOMATION which, when set to a non-empty value, is a hint to Terraform that it isn't being run in an interactive command shell and it should thus tone down the "next steps" messaging. The documentation for this setting is included as part of the "...in automation" guide since it's not generally useful in other cases. We also intentionally disclaim comprehensive support for this since we want to avoid creating an extreme number of "if running in automation..." codepaths that would increase the testing matrix and hurt maintainability. The focus is specifically on the output of the three commands we give in the automation guide, which at present means the following two situations: * "terraform init" does not include the final paragraphs that suggest running "terraform plan" and tell you in what situations you might need to re-run "terraform init". * "terraform plan" does not include the final paragraphs that either warn about not specifying "-out=..." or instruct to run "terraform apply" with the generated plan file.

terraform: ugly huge change to weave in new HCL2-oriented types Due to how deeply the configuration types go into Terraform Core, there isn't a great way to switch out to HCL2 gradually. As a consequence, this huge commit gets us from the old state to a _compilable_ new state, but does not yet attempt to fix any tests and has a number of known missing parts and bugs. We will continue to iterate on this in forthcoming commits, heading back towards passing tests and making Terraform fully-functional again. The three main goals here are: - Use the configuration models from the "configs" package instead of the older models in the "config" package, which is now deprecated and preserved only to help us write our migration tool. - Do expression inspection and evaluation using the functionality of the new "lang" package, instead of the Interpolator type and related functionality in the main "terraform" package. - Represent addresses of various objects using types in the addrs package, rather than hand-constructed strings. This is not critical to support the above, but was a big help during the implementation of these other points since it made it much more explicit what kind of address is expected in each context. Since our new packages are built to accommodate some future planned features that are not yet implemented (e.g. the "for_each" argument on resources, "count"/"for_each" on modules), and since there's still a fair amount of functionality still using old-style APIs, there is a moderate amount of shimming here to connect new assumptions with old, hopefully in a way that makes it easier to find and eliminate these shims later. I apologize in advance to the person who inevitably just found this huge commit while spelunking through the commit history.

Initialize a new or existing Terraform working directory by creating
2017-01-19 05:50:45 +01:00
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
2017-04-26 16:10:04 +02:00
necessary to run Terraform that is typically not committed to version
2017-01-19 05:50:45 +01:00
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.
2014-09-27 01:03:39 +02:00
2017-01-19 05:50:45 +01:00
If no arguments are given, the configuration in this working directory
is initialized.
2014-09-27 01:03:39 +02:00
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.
2017-01-19 05:50:45 +01:00
-get=true Download any modules for this configuration.
-get-plugins=true Download any missing plugins for this configuration.
2017-01-19 05:50:45 +01:00
-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.
2017-01-19 05:50:45 +01:00
-no-color If specified, output won't contain any color.
2015-06-22 14:14:01 +02:00
-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.

cli: allow disabling "next steps" message in terraform plan In #15884 we adjusted the plan output to give an explicit command to run to apply a plan, whereas before this command was just alluded to in the prose. Since releasing that, we've got good feedback that it's confusing to include such instructions when Terraform is running in a workflow automation tool, because such tools usually abstract away exactly what commands are run and require users to take different actions to proceed through the workflow. To accommodate such environments while retaining helpful messages for normal CLI usage, here we introduce a new environment variable TF_IN_AUTOMATION which, when set to a non-empty value, is a hint to Terraform that it isn't being run in an interactive command shell and it should thus tone down the "next steps" messaging. The documentation for this setting is included as part of the "...in automation" guide since it's not generally useful in other cases. We also intentionally disclaim comprehensive support for this since we want to avoid creating an extreme number of "if running in automation..." codepaths that would increase the testing matrix and hurt maintainability. The focus is specifically on the output of the three commands we give in the automation guide, which at present means the following two situations: * "terraform init" does not include the final paragraphs that suggest running "terraform plan" and tell you in what situations you might need to re-run "terraform init". * "terraform plan" does not include the final paragraphs that either warn about not specifying "-out=..." or instruct to run "terraform apply" with the generated plan file.

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other

const outputInitProvidersUnconstrained = `
The following providers do not have any version constraints in configuration,
so the latest version was installed.
To prevent automatic upgrades to new major versions that may contain breaking
changes, it is recommended to add version = "..." constraints to the
corresponding provider blocks in configuration, with the constraint strings
suggested below.
`
const errProviderNotFound = `
[reset][bold][red]Provider %[1]q not available for installation.[reset][red]
A provider named %[1]q could not be found in the official repository.
This may result from mistyping the provider name, or the given provider may
be a third-party provider that cannot be installed automatically.
In the latter case, the plugin must be installed manually by locating and
downloading a suitable distribution package and placing the plugin's executable
file in the following directory:
%[2]s
Terraform detects necessary plugins by inspecting the configuration and state.
To view the provider versions requested by each module, run
"terraform providers".
`
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 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.
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:
