Generally described, one or more aspects of the present application relate to prefetching container image layers for use in a cluster of compute instances. For example, the dependencies among the individual layers within the container images stored and/or executed on a cloud provider network may be analyzed. Then, the layers that are likely to be used by a user of the cloud provider network may be identified and prefetched into the caches of the compute instances provided by the cloud provider network, before execution of the container images including such layers is requested by the user. By doing so, the latency between the time a request to execute a set of container images is received and the time the execution of the set of container images is actually initiated can be reduced, thereby providing an improved and more efficient application execution experience to the user.

Predelivering container image layers for future execution of container images

Generally described, one or more aspects of the present application relate to prefetching container images for use in a cluster of virtual machines. For example, the cluster manifest may indicate an ordered list of image repositories and a set of container images that are likely to be executed on the cluster. Based on this indication, the set of container images can be prefetched onto the caches of the virtual machines in the cluster, such that when requests to execute those container images are eventually received, the container images can be accessed from the caches rather than from a remote repository.
