The Kubernetes API can be extended using Custom Resources, which represent objects that are not part of the standard Kubernetes installation. These custom resources are declared using Custom Resource Definitions (CRDs), which is a kind of resource that can be dynamically registered and unregistered without shutting down or restarting a cluster ...
This level of control enables the cluster to support upgrades and patches of the control plane nodes with minimal effort. The compute nodes can be running Red Hat CoreOS, RHEL or even Windows. OpenShift introduced the concept of routes - points of traffic ingress into the Kubernetes cluster. The Kubernetes ingress concept was modeled after this ...
Ready: The virtual platform has been established. Running: The zone booted successfully and is now running. Shutting down: The zone is in the process of shutting down – this is a temporary state, leading to "Down". Down: The zone has completed the shut down process and is down – this is a temporary state, leading to "Installed".
[28] [29] If a Proxmox node becomes unavailable or fails, the virtual machines can be automatically moved to another node and restarted. [30] The database and FUSE -based Proxmox Cluster file system (pmxcfs [ 31 ] ) makes it possible to perform the configuration of each cluster node via the Corosync communication stack with SQLite engine.
The docker node CLI utility allows users to run various commands to manage nodes in a swarm, for example, listing the nodes in a swarm, updating nodes, and removing nodes from the swarm. [39] Docker manages swarms using the Raft consensus algorithm. According to Raft, for an update to be performed, the majority of Swarm nodes need to agree on ...
When a node in a cluster fails, strategies such as "fencing" may be employed to keep the rest of the system operational. [25] [26] Fencing is the process of isolating a node or protecting shared resources when a node appears to be malfunctioning. There are two classes of fencing methods; one disables a node itself, and the other disallows ...
NASA's Nebula platform. In July 2010, Rackspace Hosting and NASA announced an open-source cloud-software initiative known as OpenStack. [7] [8] The mission statement was "to produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of public and private clouds regardless of size, by being simple to implement and massively scalable".
Increasing the power on mobile nodes may not work if, for example, the reason one node is hidden is that there is a concrete or steel wall preventing communication with other nodes. It is doubtful that one would be able to remove such an obstacle, but removal of the obstacle is another method of remedy for the hidden node problem.
