摘要： A shim layer can be incorporated into a container image for intercepting calls between an upper layer and a lower layer of the container image according to some aspects described herein. For example, a system can build an image file that includes a stacked arrangement of layers configured for deploying a software program within a container. The stacked arrangement of layers can include a lower layer including one or more objects. The stacked arrangement of layers can include an upper layer positioned above the lower layer, where the upper layer includes the software program. And the stacked arrangement of layers can include a shim layer positioned between the lower layer and the upper layer. The shim layer can include a shim, which is configured to intercept calls involving the one or more objects from the software program and responsively allow or reject the calls based on control data.

摘要： A computing device determines that an executing first operator process is to be upgraded to a second operator process in an upgrade process, wherein the first operator process maintains on a cluster of compute nodes a desired identified state of an application. The computing device prior to initiating the second operator process, determines that the upgrade process will cause an initiation of a new container of the application to replace an existing container of the application. The computing device determines that an upgrade mode associated with the first operator process is a rolling upgrade mode, wherein the existing container and the new container will execute concurrently for a period of time. The computing device makes a determination whether computing resources needed to execute the existing container and the new container concurrently are available. The computing device takes an upgrade request action based on the determination.

摘要： A method of generating container image snapshots includes scanning one or more worker nodes of a container cluster to generate an image set describing container images loaded onto the one or more worker nodes. The method also includes analyzing, by a processing device, the image set to generate an image manifest comprising at least some of the container images in the image set. The method also includes generating a snapshot from the image manifest, wherein the snapshot describes a set of container images to be used to build a new worker node. The method also includes storing the snapshot in a local memory of the container cluster. The method also includes, responsive to an instruction to provision the new worker node, loading the set of container images from the local memory to the new worker node and building a container for each of the container images in the set.
