tfplan

Run terraform plan with -target specified for autodiscovered resources/modules from given files or location or even based on git diff command result.

Install

Clone this repository into your preferred location, cd into it and invoke ln -s $PWD/tfplan /usr/local/bin/tfplan

Optional requirements

ln -s $PWD/tfapply /usr/local/bin/tfapply can be linked as well, so you can follow naming convention for apply command as well.

If landscape (install from here) is in PATH, terraform plan will be parsed with it.

Usage

$ tfplan [-f|--file filename] [-l|--limit "rule"] [--dry-run] [positional arguments]

• -f|--file filename|directory to discover resources from
• -l|--limit wildcard style rule to limit resources with (must be wrapped with " "]
• -h|--help display help
• -d|--git-diff read resources/modules from git diff (staged and not staged changes, without untracked), automatically disables reading from files even if defined
• --dry-run print steps without invoking them
• --version check current version and the newest one available, offers automatic update if newer is available
• positional arguemnts any flag from terraform, that needs to be invoked with tfplan

Examples

• $ tfplan -f . -l "google_compute_firewall.*" - will discover all files from . path (current directory) and will limits resources to google_compute_firewall only

• $ tfplan --file 10_firewall.tf -l "my_firewall_*" - will get resources from 10_firewall.tf file and limit them to those containing "my_firewall_" in the name

• $ tfplan --file 10_firewall.tf -destroy - will destroy every resource from 10_firewall.tf file

• $ tfplan --git-diff - will read resources and modules into targets from git diff

• $ tfplan --git-diff -l "google_compute_firewall.*" - will read resources from git diff and limit them to google_compute_firewall kind only

--git-diff

This flag takes git diff staged and to be staged files, excluding untracked by git, into consideration and ignores reading from files defined with other parameters.
