Requirements

The tftarget invokes the Terraform command, so Terraform must be installed on the local environment.

Getting Started

We have prepared a sandbox environment where Terraform can be run in a Docker environment, so please clone the repository and try it out.

$ git clone https://github.com/future-architect/tftarget.git

First, build localstack

$ make localstack

Then, change directory, following command.

$ cd sandbox

Now that localstack has started, you should be able to run Terraform.
Please run the following command to confirm that Terraform is functioning properly.

$ terraform init
$ terraform plan

Once you have reached this point, the preparation is complete.

Install

Go

$ go install github.com/future-architect/tftarget@latest

Homebrew

$ brew install future-architect/tap/tftarget

Download

Download the latest compiled binaries and put it anywhere in your executable path.

Simple Usage

Plan

$ tftarget plan

simple-usage-1

Executing a tftarget plan is equivalent to executing a terraform plan. The difference from a normal terraform plan is that instead of s detailed plan results, the output is a checkbox with only the resource name and action name displayed.

By selecting this checkbox and executing, the terraform plan can be executed for the selected resource with the target option.

simple-usage-2

Finally, selected result is output as a summary.

simple-usage-3

Apply

tftarget apply is the same flow until the tftarget plan and resource are selected. The difference is that after selecting a resource, you will be prompted to enter yes, which will execute terraform apply.

simple-usage-4

As with the tftarget plan, the selected resource is output as a summary.

simple-usage-5

Destroy

The use of tftarget destroy is exactly the same as that of tftarget apply, so we omit the explanation here.

Advanced Option

plan, apply, and destroy each have Flags options as shown below.

Flags:
  -f, --filter string   filter by action. You can select create, destroy, update, or replace
  -i, --items int       check box item size (default 25)
  -p, --parallel int    limit the number of concurrent operations (default 10)
  -s, --summary         summary of selected items (default true)

--filter, -f

The filter option allows you to filter actions on the first resource selection screen. For example, if you want to display only newly created resources as an option, do the following

tftarget apply -f create

This option is not available for combined use. For example, the following commands are treated as invalid

tftarget apply -f create destroy

--items, -i

This option allows you to change the number of checkbox choices. The default setting is 25. If you wish to increase the number of checkboxes to 50, do the following.

tftarget apply -i 50

--parallel, -p

--parallel is equivalent to the -parallelism=n option in terraform. The default is set to 10.

tftarget apply -p 30

--summary, -s

--summary option is set to true by default. If it is set to false, the following output will be hidden.

simple-usage-5

tftarget apply -s false
