Abstract: Techniques are disclosed relating to upgrading nodes. A computer system may detect that an updated node image has been created that is an update to a previous node image used to deploy a plurality of nodes into an environment associated with the computer system. The computer system may determine an upgrade order in which to upgrade a set of the plurality of nodes. The upgrade order may be determined based on a rank associated with a given node of the set of nodes by a ranking service. The computer system may then upgrade the set of nodes according to the upgrade order. The upgrading of a first node of the set of nodes may include deploying a second node based on the updated node image and then evicting a set of application pods from the first node and redeploying the set of application pods onto the second node.

Abstract: Techniques are disclosed relating to upgrading nodes. A computer system may detect that there is an update to a node image used to deploy a set of nodes managed by the computer system. The computer system may select, for an upgrade process, a first node from the set of nodes that includes a first volume used to store data of applications executing on that first node. The computer system may upgrade the first node by deploying a second node running the updated node image, transition the first node to a read-only mode in which read transactions but not write transactions are routed to the applications, and copy particular data from the first volume of the first node to a second volume of the second node. The computer system may, after completion of the copy operation, evict the applications from the first node and redeploy them on the second node.
