I am using kubernetes cluster with 3 master and 3 agents which is created using Azure container service (ACS).
I have created the 50+ deployments using helm with one pod each and it is working fine. Out of three agents, only two agents are hosting half deployments on it. The third agent doesn't have any pod created on it except system/kubernetes created pods.
Any inputs will be helpful. Thanks in advance.
run the kubectl describe node <3rdagent name> command and check Taints is set for NoSchedule

if not you can label this node and schedule the pod on this with label see its runs on this node.
