Abstract
Shared container image layer removal is provided. It is determined whether layer metadata corresponding to a selected layer of a container image includes a referenced image identifier corresponding to a reference shared layer of an other container image stored in local storage based on an analysis of the layer metadata. In response to determining that the layer metadata corresponding to the selected layer does include the referenced image identifier corresponding to the reference shared layer of the other container image stored in the local storage based on the analysis of the layer metadata, it is determined that the selected layer of the container image is a duplicate shared layer having same content as the reference shared layer. The container image containing the selected layer that is the duplicate shared layer is removed from the local storage to decrease space utilization of the local storage and thereby increase performance.
