** Description changed:
[Impact]
When creating a new "cluster"that overrides the fixed network defined in
the cluster template, but not the subnet.
It would be expected that the cluster create request fails with a 400
error since the client is submitting an invalid request.
[Environment]
Focal Ussuri
[Test Case]
1. Create a new cluster template WITHOUT a fixed network/subnet set.
openstack coe cluster template create k8s-cluster-template \
- --image fedora-coreos-32 \
- --keypair testkey \
- --external-network ext_net \
- --flavor m1.small \
- --network-driver flannel \
- --coe kubernetes \
- --fixed-network admin_net \
- --fixed-subnet admin_subnet
+ --image fedora-coreos-32 \
+ --keypair testkey \
+ --external-network ext_net \
+ --flavor m1.small \
+ --network-driver flannel \
+ --coe kubernetes \
+ --fixed-network admin_net \
+ --fixed-subnet admin_subnet
2. Create a new cluster using the template previously created and select
an existing network
openstack coe cluster create \
- --cluster-template k8s-cluster-template \
- --timeout 120 \
- --fixed-network private \
- k8scluster
+ --cluster-template k8s-cluster-template \
+ --timeout 120 \
+ --fixed-network private \
+ k8scluster
Expected result
The cluster gets created
Actual result:
The cluster creation fails with the following error:
$ openstack coe cluster show k8scluster -f json -c faults | jq -r '.faults'
