Hi please help with node and pod affinity for below issue
i have 3 node cluster(1manager, 2 worker) where i want to create all the pods in one single node.
first used deploy.yaml to create deployment where all PODs created in kslave1 node as desired and then when trying with affinity.yaml to create another deployment its getting created in other node where as expectation is to get created in same node as previous deployment. please help to identify the issue.
deploy.yaml
