## Problem In several workflows, we have repeating code which is separated into two steps: ```bash mkdir -p $(pwd)/.docker-custom echo DOCKER_CONFIG=/tmp/.docker-custom >> $GITHUB_ENV ... rm -rf $(pwd)/.docker-custom ``` Such copy-paste is prone to errors; for example, in one case, instead of `$(pwd)/.docker-custom`, we use `/tmp/.docker-custom`, which is shared between workflows. ## Summary of changes - Create a new action `actions/set-docker-config-dir`, which sets `DOCKER_CONFIG` and deletes it in a Post action part
