An AWK script that supresses terraform helm_release metadata attributes

README.md

Motivation

The terraform helm provider is rather noisy printing unnecessary metadata in the plan output making it hard to review changes. This awk script redacts unnecessary field from the output to make it easier to review.

Usage

terraform plan -out plan.tfplan | awk -f supress_helm_release.awk
terraform show -no-color plan.tfplan | awk -f supress_helm_release.awk

supress_helm_release.awk

BEGIN { in_block = 0; redact = 0 }
/^(\[0m)?  (\[3[123]m)?[~+-](\[0m\[0m)? resource "helm_release" "[a-zA-Z0-9_-]+" {$/ { in_block = 1; print; next }
in_block && /^    }$/ { in_block = 0; redact = 0; print; next }
in_block && /^      (\[3[123]m)?[~+-](\[0m\[0m)? (metadata|values) +=/ { redact = 1; next }
in_block && redact && /^      (\[3[123]m)?[~+-](\[0m\[0m)? [a-zA-Z0-9_-]+/ { redact = 0; print; next }
redact { next }
{ print }
