network %q not found

Error message

network %q not found

What it means

When Neutron answers successfully but no network matches cluster.Spec.Networking.NetworkID, FindVPCInfo returns nil and kOps returns "network %q not found". This cleanly separates "the network ID is wrong" from "the API call failed" so the user knows to fix the network identifier.

Solutions

1. Confirm the ID: `openstack network list` in the target project and copy the exact UUID for --os-network.
2. Ensure OS_PROJECT_NAME/OS_PROJECT_ID and OS_REGION_NAME match the project/region owning the network.
3. If the network was deleted, create/choose another and update the flag.

Example fix

// before
--os-network 0f1e2d3c-wrong-id
// after
--os-network $(openstack network show mynetwork -f value -c id)

out, err := exec.Command("openstack", "network", "show", networkID, "-f", "value", "-c", "id").Output()
if err != nil || strings.TrimSpace(string(out)) != networkID {
    return fmt.Errorf("network %s not visible in current project/region", networkID)
}

if strings.Contains(err.Error(), "network \"") && strings.Contains(err.Error(), "not found") {
    // run `openstack network list`, pick the correct UUID, update --os-network and retry
}

When it happens

Trigger: `kops create cluster --cloud openstack --os-network net-typo ...` with a mistyped/foreign/deleted network UUID, or a network in a different project/region than the authenticated one.

Common situations: Copying a network ID from another project's dashboard; network deleted after being written into scripts; using a router or subnet UUID by mistake instead of the network UUID; wrong OS_PROJECT_NAME selecting an empty project.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
