Class Method Details

.apply(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform apply command which creates or updates infrastructure according to terraform configuration files in the provided directory.

By default, terraform will generate a new plan and present it for approval before taking any action. Alternatively, the command accepts a plan file created by a previous invocation, in which case terraform will take the actions described in that plan without any confirmation prompt.

Examples:

Basic Invocation

RubyTerraform.apply(
  directory: 'infra/networking',
  vars: {
    region: 'eu-central'
  })

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

    Additional options controlling the invocation of the command.

Options Hash (parameters):

  • :directory (String) —

    The path to a directory containing terraform configuration (deprecated in terraform 0.14, removed in terraform 0.15, use :chdir instead).

  • :plan (String) —

    The path to a pre-computed plan to be applied.

  • :chdir (String) —

    The path of a working directory to switch to before executing the given subcommand.

  • :auto_approve (Boolean) — default: false —

    If true, skips interactive approval of the generated plan before applying.

  • :backup (String) —

    The path to backup the existing state file before modifying; defaults to the :state_out path with ".backup" extension; set :no_backup to true to skip backups entirely.

  • :compact_warnings (Boolean) — default: false —

    When true, if terraform produces any warnings that are not accompanied by errors, they are shown in a more compact form that includes only the summary messages.

  • :input (Boolean) — default: true —

    When false, will not ask for input for variables not directly set.

  • :lock (Boolean) — default: true —

    When true, locks the state file when locking is supported; when false, does not lock the state file.

  • :lock_timeout (String) — default: "0s" —

    The duration to retry a state lock.

  • :no_backup (Boolean) — default: false —

    When true, no backup file will be written.

  • :state_out (String) —

    The path to write state to that is different than :state; this can be used to preserve the old state.

  • :target (String) —

    The address of a resource to target; if both :target and :targets are provided, all targets will be passed to terraform.

  • :targets (Array<String>) —

    An array of resource addresses to target; if both :target and :targets are provided, all targets will be passed to terraform.

.force_unlock(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform force-unlock command which manually unlocks the state for the defined configuration.

This will not modify your infrastructure. This command removes the lock on the state for the current workspace. The behavior of this lock is dependent on the backend being used. Local state files cannot be unlocked by another process.

Examples:

RubyTerraform.force_unlock(
  lock_id: '50e844a7-ebb0-fcfd-da85-5cce5bd1ec90')

Parameters:

  • :environment (Hash<String, String>) —

    A map of environment variables to expose at command invocation time.

.format(parameters = {}, invocation_options = {}) ⇒ Object Also known as: fmt Originally defined in module ClassMethods

Invokes the terraform fmt command which rewrites all terraform configuration files to a canonical format.

Both configuration files (.tf) and variables files (.tfvars) are updated. JSON files (.tf.json or .tfvars.json) are not modified.

If :directory is not specified in the parameters map then the current working directory will be used. If :directory is "-" then content will be read from the standard input. The given content must be in the terraform language native syntax; JSON is not supported.

Examples:

Basic Invocation

RubyTerraform.format(
  directory: 'infra/networking')

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

  • invocation_options (Hash<String, Object>) (defaults to: {}) —

    Additional options controlling the invocation of the command.

Options Hash (parameters):

  • :directory (String) —

    The path to a directory containing terraform configuration (deprecated in terraform 0.14, removed in terraform 0.15, use :chdir instead).

  • :chdir (String) —

  • :diff (Boolean) — default: false —

    If true, displays diffs of formatting changes.

  • :check (Boolean) — default: false —

    If true, checks if the input is formatted; if any input is not properly formatted, an Errors::ExecutionError will be thrown.

  • :no_color (Boolean) — default: false —

    Whether or not the output from the command should be in color.

  • :recursive (Boolean) — default: false —

    If true, also processes files in subdirectories; by default, only the provided :directory is processed.

Options Hash (invocation_options):

  • :environment (Hash<String, String>) —

    A map of environment variables to expose at command invocation time.

.get(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform get command which downloads and installs modules needed for the given configuration.

This recursively downloads all modules needed, such as modules imported by the root and so on. If a module is already downloaded, it will not be redownloaded or checked for updates unless :update is true.

Module installation also happens automatically by default as part of the #init command, so you should rarely need to run this command separately.

Examples:

Basic Invocation

RubyTerraform.get(
  directory: 'infra/networking')

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

  • invocation_options (Hash<String, Object>) (defaults to: {}) —

    Whether or not the output from the command should be in color.

Options Hash (invocation_options):

  • :environment (Hash<String, String>) —

    A map of environment variables to expose at command invocation time.

.graph(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform graph command which outputs the visual execution graph of terraform resources according to either the current configuration or an execution plan.

The graph is outputted in DOT format. The typical program that can read this format is GraphViz, but many web services are also available to read this format.

The :type option can be used to control the type of graph shown. Terraform creates different graphs for different operations. See the options below for the list of types supported. The default type is "plan" if a configuration is given, and "apply" if a plan file is passed as an argument.

Examples:

Basic Invocation

RubyTerraform.graph

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

    In prior versions of terraform, specified the depth of modules to show in the output (deprecated).

Options Hash (invocation_options):

  • :environment (Hash<String, String>) —

    A map of environment variables to expose at command invocation time.

.import(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform import command which imports existing infrastructure into your terraform state.

This will find and import the specified resource into your terraform state, allowing existing infrastructure to come under terraform management without having to be initially created by terraform.

The :address specified is the address to import the resource to. Please see the documentation online for resource addresses. The :id is a resource-specific ID to identify that resource being imported. Please reference the documentation for the resource type you're importing to determine the ID syntax to use. It typically matches directly to the ID that the provider uses.

The current implementation of terraform import can only import resources into the state. It does not generate configuration. A future version of terraform will also generate configuration.

Because of this, prior to running terraform import it is necessary to write a resource configuration block for the resource manually, to which the imported object will be attached.

This command will not modify your infrastructure, but it will make network requests to inspect parts of your infrastructure relevant to the resource being imported.

Examples:

Basic Invocation

RubyTerraform.import(
  directory: 'infra/networking',
  address: 'a.resource.address',
  id: 'a-resource-id',
  vars: {
    region: 'eu-central'
  })

  • invocation_options (Hash<String, Object>) (defaults to: {}) —

    Additional options controlling the invocation of the command.

Options Hash (parameters):

  • :directory (String) —

    The path to a directory containing terraform configuration (deprecated in terraform 0.14, removed in terraform 0.15, use :chdir instead).

  • :address (String) —

    The address to import the resource to; required.

  • :id (String) —

    The resource-specific ID identifying the resource being imported; required.

  • :chdir (String) —

    The path of a working directory to switch to before executing the given subcommand.

  • :backup (String) —

    The path to backup the existing state file before modifying; defaults to the :state_out path with ".backup" extension; set :no_backup to true to skip backups entirely (legacy).

  • :allow_missing_config (Boolean) — default: false —

    Whether or not to allow import when no resource configuration block exists.

  • :input (Boolean) — default: true —

    When false, will not ask for input for variables not directly set.

  • :var_files (Array<String>) —

    An array of paths to terraform var files; if both :var_file and :var_files are provided, all var files will be passed to terraform.

  • :ignore_remote_version (Boolean) — default: false —

    If true, when using the enhanced remote backend with Terraform Cloud, continue even if remote and local Terraform versions differ; this may result in an unusable Terraform Cloud workspace, and should be used with extreme caution.

.init(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform init command which initializes 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.

Examples:

Basic Invocation

RubyTerraform.providers

.providers_lock(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform providers lock command which writes out dependency locks for the configured providers.

Normally the dependency lock file (.terraform.lock.hcl) is updated automatically by "terraform init", but the information available to the normal provider installer can be constrained when you're installing providers from filesystem or network mirrors, and so the generated lock file can end up incomplete.

The "providers lock" subcommand addresses that by updating the lock file based on the official packages available in the origin registry, ignoring the currently-configured installation strategy.

After this command succeeds, the lock file will contain suitable checksums to allow installation of the providers needed by the current configuration on all of the selected platforms.

By default this command updates the lock file for every provider declared in the configuration. You can override that behavior by providing one or more provider source addresses on the command line.

Examples:

Basic Invocation

RubyTerraform.providers_lock(
  fs_mirror: "/usr/local/terraform/providers",
  platforms: ["windows_amd64", "darwin_amd64", "linux_amd64"],
  provider: "tf.example.com/ourcompany/ourplatform")

.providers_mirror(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform providers mirror command which saves local copies of all required provider plugins.

Populates a local directory with copies of the provider plugins needed for the current configuration, so that the directory can be used either directly as a filesystem mirror or as the basis for a network mirror and thus obtain those providers without access to their origin registries in future.

The mirror directory will contain JSON index files that can be published along with the mirrored packages on a static HTTP file server to produce a network mirror. Those index files will be ignored if the directory is used instead as a local filesystem mirror.

Examples:

Basic Invocation

RubyTerraform.providers_mirror(
  directory: './plugins',

.state_move(parameters = {}, invocation_options = {}) ⇒ Object Also known as: state_mv Originally defined in module ClassMethods

Invokes the terraform state mv command which moves an item in the state.

This command will move an item matched by the address given to the destination address. This command can also move to a destination address in a completely different state file.

This can be used for simple resource renaming, moving items to and from a module, moving entire modules, and more. And because this command can also move data to a completely new state, it can also be used for refactoring one configuration into multiple separately managed Terraform configurations.

This command will output a backup copy of the state prior to saving any changes. The backup cannot be disabled. Due to the destructive nature of this command, backups are required.

If you're moving an item to a different state file, a backup will be created for each state file.

Examples:

Basic Invocation

RubyTerraform.state_move(
  source: 'packet_device.worker',
  destination: 'packet_device.helper')

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

.state_pull(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform state pull command which pulls the state from its location, upgrades the local copy, and outputs it to stdout.

This command "pulls" the current state and outputs it to stdout. As part of this process, Terraform will upgrade the state format of the local copy to the current version.

The primary use of this is for state stored remotely. This command will still work with local state but is less useful for this.

Examples:

Basic Invocation

RubyTerraform.state_pull

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

  • invocation_options (Hash<String, Object>) (defaults to: {}) —

Options Hash (invocation_options):

  • :environment (Hash<String, String>) —

    A map of environment variables to expose at command invocation time.

.state_push(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform state push command which updates remote state from a local state file.

This command "pushes" a local state and overwrites remote state with a local state file. The command will protect you against writing an older serial or a different state file lineage unless you pass true for the :force option.

This command works with local state (it will overwrite the local state), but is less useful for this use case.

If :path is "-", then this command will read the state to push from stdin. Data from stdin is not streamed to the backend: it is loaded completely (until pipe close), verified, and then pushed.

Examples:

Basic Invocation

RubyTerraform.state_push(
  path: 'some/statefile.tfstate')

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

  • invocation_options (Hash<String, Object>) (defaults to: {}) —

  • :force (Boolean) — default: false —

    When true, writes the state even if lineages don't match or the remote serial is higher.

  • :lock (Boolean) — default: true —

    When true, locks the state file when locking is supported; when false, does not lock the state file.

  • :lock_timeout (String) — default: "0s" —

    The duration to retry a state lock.

  • :ignore_remote_version (Boolean) —

Options Hash (invocation_options):

  • :environment (Hash<String, String>) —

    A map of environment variables to expose at command invocation time.

.state_remove(parameters = {}, invocation_options = {}) ⇒ Object Also known as: state_rm Originally defined in module ClassMethods

Invokes the terraform state rm command which removes one or more items from the Terraform state, causing Terraform to "forget" those items without first destroying them in the remote system.

This command removes one or more resource instances from the Terraform state based on the addresses given. You can view and list the available instances with #state_list.

If you give the address of an entire module then all of the instances in that module and any of its child modules will be removed from the state.

If you give the address of a resource that has "count" or "for_each" set, all of the instances of that resource will be removed from the state.

.taint(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform taint command which marks a resource instance as not fully functional.

Terraform uses the term "tainted" to describe a resource instance which may not be fully functional, either because its creation partially failed or because you've manually marked it as such using this command.

This will not modify your infrastructure directly, but subsequent Terraform plans will include actions to destroy the remote object and create a new object to replace it.

You can remove the "taint" state from a resource instance using the #untaint command.

The address is in the usual resource address syntax, such as:

  • aws_instance.foo
  • aws_instance.bar
  • module.foo.module.bar.aws_instance.baz

Use your shell's quoting or escaping syntax to ensure that the address will reach Terraform correctly, without any special interpretation.

Examples:

Basic Invocation

RubyTerraform.taint(
  address: 'aws_security_group.allow_all')

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

  • invocation_options (Hash<String, Object>) (defaults to: {}) —

    Additional options controlling the invocation of the command.

Options Hash (parameters):

  • :address (String) —

    The module address or absolute resource address of the resource instance to taint; required.

  • :chdir (String) —

    The path of a working directory to switch to before executing the given subcommand.

  • :allow_missing (Boolean) — default: false —

    If true, the command will succeed (i.e., will not throw an Errors::ExecutionError) even if the resource is missing.

  • :backup (String) —

    The path to backup the existing state file before modifying; defaults to the :state_out path with ".backup" extension; set :no_backup to true to skip backups entirely.

  • :lock (Boolean) — default: true —

    When true, locks the state file when locking is supported; when false, does not lock the state file.

  • :lock_timeout (String) — default: "0s" —

    The duration to retry a state lock.

  • :no_backup (Boolean) — default: false —

    When true, no backup file will be written.

  • :state (String) —

    The path to the state file from which to read state and in which to store state (unless :state_out is specified); defaults to "terraform.tfstate".

  • :state_out (String) —

    The path to write state to that is different than :state; this can be used to preserve the old state.

  • :ignore_remote_version (Boolean) — default: false —

    Whether or not to continue even if remote and local Terraform versions are incompatible; this may result in an unusable workspace, and should be used with extreme caution.

Options Hash (invocation_options):

  • :environment (Hash<String, String>) —

    A map of environment variables to expose at command invocation time.

.test(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Terraform discovers test files in the configured test directory (by default tests) and in the root module, then runs each run block in turn, reporting on the outcome of the assertions.

Examples:

Basic Invocation

RubyTerraform.test(
  filters: ['tests/network.tftest.hcl'],
  verbose: true)

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

  • invocation_options (Hash<String, Object>) (defaults to: {}) —

    Additional options controlling the invocation of the command.

Options Hash (parameters):

  • :chdir (String) —

    The path of a working directory to switch to before executing the given subcommand.

  • :cloud_run (String) —

    If set, executes the tests remotely using the given Terraform Cloud/Enterprise module source address rather than running them locally.

  • :filter (String) —

    Restrict which test files are executed; if both :filter and :filters are provided, all filters will be passed to terraform.

  • :filters (Array<String>) —

    An array of test file paths to restrict which test files are executed; if both :filter and :filters are provided, all filters will be passed to terraform.

  • :json (Boolean) — default: false —

    Whether or not to produce output in a machine-readable JSON format.

  • :no_color (Boolean) — default: false —

    Whether or not the output from the command should be in color.

    A map of environment variables to expose at command invocation time.

.untaint(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform untaint command which removes the 'tainted' state from a resource instance.

Terraform uses the term "tainted" to describe a resource instance which may not be fully functional, either because its creation partially failed or because you've manually marked it as such using the #taint command.

This command removes that state from a resource instance, causing Terraform to see it as fully-functional and not in need of replacement.

This will not modify your infrastructure directly. It only avoids Terraform planning to replace a tainted instance in a future operation.

Examples:

Basic Invocation

RubyTerraform.untaint(
  name: 'aws_security_group.allow_all')

Parameters:

  • parameters (defaults to: {}) —

    The parameters used to invoke the command

  • invocation_options (Hash<String, Object>) (defaults to: {}) —

    Additional options controlling the invocation of the command.

Options Hash (parameters):

  • :name (String) —

    The name of the resource instance to untaint; required.

  • :chdir (String) —

    The path of a working directory to switch to before executing the given subcommand.

  • :allow_missing (Boolean) — default: false —

    If true, the command will succeed (i.e., will not throw an Errors::ExecutionError) even if the resource is missing.

  • :backup (String) —

    The path to backup the existing state file before modifying; defaults to the :state_out path with ".backup" extension; set :no_backup to true to skip backups entirely.

  • :lock (Boolean) — default: true —

    When true, locks the state file when locking is supported; when false, does not lock the state file.

  • :lock_timeout (String) —

    The duration to retry a state lock; defaults to "0s".

  • :no_backup (Boolean) — default: false —

    When true, no backup file will be written.

  • :no_color (Boolean) — default: false —

    Whether or not the output from the command should be in color.

  • :state (String) —

    The path to the state file from which to read state and in which to store state (unless :state_out is specified); defaults to "terraform.tfstate".

  • :state_out (String) —

    The path to write state to that is different than :state; this can be used to preserve the old state.

  • :ignore_remote_version (Boolean) — default: false —

    Whether or not to continue even if remote and local Terraform versions are incompatible; this may result in an unusable workspace, and should be used with extreme caution.

Options Hash (invocation_options):

  • :environment (Hash<String, String>) —

    A map of environment variables to expose at command invocation time.

.validate(parameters = {}, invocation_options = {}) ⇒ Object Originally defined in module ClassMethods

Invokes the terraform validate command which checks whether a configuration is valid.

Validates the configuration files in a directory, referring only to the configuration and not accessing any remote services such as remote state, provider APIs, etc.

Validate runs checks that verify whether a configuration is syntactically valid and internally consistent, regardless of any provided variables or existing state. It is thus primarily useful for general verification of reusable modules, including correctness of attribute names and value types.

It is safe to run this command automatically, for example as a post-save check in a text editor or as a test step for a re-usable module in a CI system.

Validation requires an initialized working directory with any referenced plugins and modules installed. To initialize a working directory for validation without accessing any configured remote backend, use the #init command passing :backend as false.

To verify configuration in the context of a particular run (a particular target workspace, input variable values, etc), use the #plan command instead, which includes an implied validation check.

Basic Invocation

RubyTerraform.validate(
  directory: 'infra/networking')
