## Description

This is a tool that performs destination tasks when attaching multiple tags to a single kaniko image build.

## Configuration

kwd is basically a binary wrapper for kaniko.

When running kwd, it reads the environment variables specified below and passes the corresponding arguments to kaniko.
If execution arguments are given to kwd, these are passed transparently to the kaniko process.

| Environment variables     | Required | Default Value      | Description                                                                                                   |
