In the above command, we added the toleration for the taint “NoSchedule” having key “node-role.kubernetes. tolerations:Īdd tolerations at namespace level oc annotate namespace NAMESPACE '/defaultTolerations=' To allow pods to run on the tainted node, one must add tolerations in the pod. 1 I am looking to apply existing annotations on a Kubernetes resource to the underlying YAML configuration files. 1 I believe that I must create multiple Ingress resources to achieve the desired effect, but must ask, is it possible to have multiple rewrite annotations with nginx (community) controller for the same host I have the following, but it wont work, as I understand it, because there is no way to link the rewrite rule to the path explicitly.

Oc adm taint nodes NODE_NAME /storage:NoScheduleĪbove command prevents the scheduling of pods on the nodes using the key name “/storage” and the Operator “Exists” (as we have not defined any value here). Annotations containing kubernetes.io and k8s.io are ignored because these. For example, the effect “NoSchedule” prevents the scheduling of pods on a node which has this taint oc adm taint nodes NODE_NAME KEY=VALUE:NoSchedule These are annotations to add to every child resource, such as StatefulSet and Service. There are different types of default Taints available. You can optionally store configuration information or a bootstrap script in this bucket, and the containers in your Pod can read the file from the bucket and load it into your application. To control the scheduling of pods on a node, we can add taints to a node. You can run the following command to create an example policy file that allows read-only access to an Amazon S3 bucket. For example: Figure 9: A YAML file with a ytt.

In order to run the pods of a namespace on a specific node, we add can a node selector at namespace levelįor example, If a node has a label “/worker=” oc annotate namespace NAMESPACE 'openshift.io/node-selector=/worker=' A ytt annotation is a YAML comment of a specific format it attaches behavior to a node. Add label to a Node oc label node NODE_NAME /storage=Ībove command is used to mark a node as a storage node using the label “/storage=” Add node selector at namespace level
