How to delete a project's Docker Layer Cache
Previously, you would have to wait for 3 days of no builds to reset the DLC Cache or remove it from your config. This is now possible immediately via the CircleCI CLI.
Step 1
Confirm you are on version v0.1.24705 or later of the CircleCI CLI.
circleci version
Step 2
Please run the following command for the project for which you wish to delete the DLC for:
circleci project dlc purge <vcs-type> <org-name> <project-name> [flags]
You can also delete your DLC cache via the UI
Navigate to your project on app.circleci.com
Click Project Settings.
Navigate to Docker Layer Caching.
Click Delete Cache Contents.
