Abstract
Techniques for managing node failures in container environments are disclosed. In one example, a method determines when a first node executing at least one containerized workload has failed. In response to determining the first node has failed, the method marks a configuration object for the first node with an indicator that the first node is not to be used to schedule execution of a subsequent containerized workload, isolates from the first node one or more storage volumes used by the first node, and deletes configuration objects for the one or more storage volumes and for the containerized workload. The method then causes creation of a replacement containerized workload for execution on a second node, removes one or more artifacts associated with the containerized workload from the first node, and removes the indicator from the configuration object for the first node.
