Warning: Once you delete an artifact, it can not be restored.
By default, GitHub stores build logs and artifacts for 90 days, and this retention period can be customized. For more information, see "Usage limits, billing, and administration."
在 GitHub.com 上，导航到仓库的主页面。
Under your repository name, click Actions.
Under Artifacts, click next to the artifact you want to remove.
Retention periods for artifacts and logs can be configured at the repository, organization, and enterprise level. For more information, see "Usage limits, billing, and administration."
You can also define a custom retention period for individual artifacts using the
actions/upload-artifact action in a workflow. For more information, see "Storing workflow data as artifacts."
You can use the API to confirm the date that an artifact is scheduled to be deleted. For more information, see the
expires_at value returned by "List artifacts for a repository."
