Near-zero downtime maintenance of containerized applications can be achieved via a modified rolling update strategy for a container orchestration platform. During deployment of a first set of containers based on a first deployment that specifies an image of a first software version and a grace period for preserving existing connections to the first set of containers, a second deployment object is received that specifies an image of a second software version and a minimum execution time for a second set of containers after which new connections to the second set of containers are allowed. After deployment of the second set of containers, new connections to the second set of containers are not enabled until the respective containers have executed for the minimum execution time. Existing connections to each container of the first set of containers are preserved until the earlier of their completion or expiration of the grace period.
