Run terraform-zap to skip over ignored (likely protected) Terraform resources, while destroying all other resources similarly to terraform destroy.

terraform must still be installed and residing within PATH, since terraform-zap is just a binary wrapper over terraform.


Currently if any of the .tf files contain prevent_destroy = true for any of the resources, terraform destroy will fail, with no flag provisioned to force terraform to skip such resources.

This script wrapper helps to alleviate the issue by parsing .tfzignore file in the current working directory, where the .tf files are residing in, to skip over specified resource names, in a similar fashion to .gitignore.

Example .tfzignore file (TOML format)

exact = [

If there are resources that exactly match the names above, these resources are automatically skipped, solving the problem of having to type complicated commands in order to skip the above resources to possibly resolve the prevent_destroy = true issue, with just a terraform-zap command.


Direct download for Linux x86_64

The easiest way is to run the install script using shell as shown below.

curl -sSf https://raw.githubusercontent.com/guangie88/terraform-zap/master/install-linux.sh | sudo sh

You will need to run as root, or run via sudo, since the script will place terraform-zap binary file into /usr/local/bin/.

You may also choose to visit releases and download the latest version of statically built binary in the zip asset.

Via cargo install (works for Linux, Windows and Mac)

You will first need to install cargo from https://rustup.rs/. The installation process should be very straightforward for any major architecture and operating system.

After which, run cargo install terraform-zap for the installation. This will automatically fetch terraform-zap CLI application from crates.io, compile and install into your Cargo installation binary directory.

If terraform-zap was already installed, run cargo install -f terraform-zap instead.

How to run

With .tfzignore file in place, simply run terraform-zap. You should see mainly terraform destroy logs in place, but the ignored resources should now no longer appear during the confirmation.

If previously there were resources with prevent_destroy = true set, if these resources are correctly ignored, the confirmation prompt should appear properly.

If you need to pass arguments to terraform destroy instead, use positional arguments, for e.g.

terraform-zap -vvv -- -no-color -var "foo=bar"

-vvv is passed into terraform-zap, while -no-color, -var and "foo=bar" are passed into terraform destroy.

For more CLI argument details, type terraform-zap -h.

terraform zap instead of terraform-zap (for bash set-up)

It is possible to allow terraform zap [...] to run terraform-zap [...], by using a function that is exported on startup. This makes the external program look like part of a terraform subcommand.

Note that this is purely cosmetic and optional.

Add the following bash function to the any of your startup script (e.g. ~/.bashrc), to allow the above

terraform() {
    if [[ $1 == "zap" ]]; then
        command terraform-zap "${@:2}"
        command terraform "${@:1}"

Either restart the current terminal, or run source ~/.bashrc (if following the example), and try terraform zap to check if the above function is working as intended. Running in non-Terraform directory should result in No state file was found! error message being shown, signifying that the function is correctly set up.


Pull requests are welcome to facilitate improvements to the repository.


Thanks to @chrissng for providing the original terraform destroy command that only targets non-protected resources. The original command line is as follow:

TARGETS=$(for I in $(terraform state list | grep -v postgresql); \
    do echo " -target $I"; done); \
    echo terraform destroy $TARGETS
