The disclosed computer-implemented method for performing live migrations of software containers may include (i) identifying a request to migrate a software container from a source computing system to a target computing system while a process executes within the software container, (ii) creating a checkpoint of the process in execution (iii) transferring the checkpoint to the target computing system, (iv) updating the checkpoint recurrently by recurrently creating an incremental checkpoint of the process and merging the incremental checkpoint into the checkpoint, (v) predicting, before updating the checkpoint with an iteration of the incremental checkpoint and based on a size of the iteration of the incremental checkpoint, that finalizing a migration of the software container to the target computing system would meet a predetermined time objective, and (vi) finalizing the migration of the software container to the target computing system. Various other methods, systems, and computer-readable media are also disclosed.

The disclosed computer-implemented method for rerouting data sent between application containers and storage containers may include (1) identifying an application container, a storage container that stores data for the application container, and a host that hosts both the application container and the storage container, (2) configuring the application container and the storage container to share a namespace on the host, (3) creating, within the shared namespace on the host, a resource that enables the application container and the storage container to share data, and (4) rerouting at least one item of data sent between the application container and the storage container to pass through the resource in the shared namespace rather than through a kernel of the host. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for rerouting data sent between application containers and storage containers

The disclosed computer-implemented method for provisioning containers in computer clusters may include (1) identifying a request to provision a container on a host system within a cluster, (2) determining that a missing storage layer image is not locally stored at the host system and initiating a transfer of the missing storage layer image to the host system, (3) creating the container and executing an application within the container on the host system before the missing storage layer image has been transferred to the host system, (4) remotely resolving a read request by reading from an instance of the missing storage layer image that is stored at a separate host system within the cluster, and (5) resolving a subsequent read request by reading from an instance of the missing storage layer image that is locally stored at the host system. Various other methods, systems, and computer-readable media are also disclosed.
