- The Buildah package provides a command line tool that can be used to
- Create a working container, either from scratch or using an image as a starting point
- Create an image, either from a working container or via the instructions in a Dockerfile
- Images can be built in either the OCI image format or the traditional upstream Docker image format
- Mount a working container's root file system for manipulation
- Unmount a working container's root file system
- Use the updated contents of a container's root file system as a file system layer to create a new image
- Delete a working container or an image
- Rename a local container
