GKE
GKE could not schedule the pod because nodes did not have free requested pod ports
0/1 nodes are available: 1 node(s) didn't have free ports for the requested pod ports.
GKE could not place the pod on a node because the requested hostPort is already in use and the node does not have a free matching port.
Observed message
0/1 nodes are available: 1 node(s) didn't have free ports for the requested pod ports.
Why it happens
- Multiple pods on the same node are trying to use the same hostPort value.
- The workload relies on hostPort, which limits scheduling flexibility.
- The current node set does not have any free host ports matching the pod requirements.
How to fix it
- Review pod manifests and make sure hostPort values are unique where required.
- Prefer NodePort or other service patterns instead of hostPort where possible.
- Reschedule or redesign the workload so it does not require conflicting host port bindings.
