* fix(flannel): default the interface to each host's default IPv4 interface
- Replace the hardcoded flannel_iface: eth0 with a per-host default derived
from ansible_facts.default_ipv4.interface
- KVM/cloud hosts that are not named eth0 (e.g. enp1s0, ens3) now resolve the
interface automatically instead of failing the k3s_node_ip lookup
- Update the commented calico_iface / cilium_iface examples to match
- Co-authored-by: Fritz Dunkel <677609+FinalDoom@users.noreply.github.com>
- Fixes#621
* test(flannel): add regression test for per-host interface default
- Add a focused test that renders the sample inventory's flannel_iface
expression against fake ansible facts
- Assert a non-eth0 host (enp1s0, ens3) resolves its own interface and that
the expression defaults from ansible_facts.default_ipv4.interface
- Wire it as a local pre-commit hook (default-interface-test)
* test(molecule): assert nodes register a non-loopback InternalIP
- Add a flannel-scenario verify assertion that every node reports an
InternalIP derived from its configured flannel_iface
- Guards against k3s binding to 127.0.0.1 instead of the cluster interface
- Complements the pre-commit default-interface test with an end-to-end check
* fix(calico): support split CRDs for current releases
- Download the v1_crd_projectcalico_org.yaml bundle before the operator
- Apply both files with server-side apply and force-conflicts per the
upstream upgrade procedure
- Wait for the operator Deployment and for the managed CRDs to be
Established after the operator starts
- Replace the create/rescue/replace flow with an idempotent apply that
no longer conceals partial failures
- Verify TigeraStatus for calico and apiserver is Available, not just
that Pods exist
* feat(dependencies): upgrade supported cluster components
- Bump K3s to v1.36.2+k3s1, Calico to v3.32.1, Cilium to v1.20.0,
kube-vip to v1.2.2, kube-vip cloud provider to v0.0.12, and MetalLB to
v0.16.0 across sample inventory, role defaults, and argument specs
- Pin the Cilium CLI with a new cilium_cli_tag (v0.19.7) instead of the
floating stable.txt lookup
- Replace the CiliumBGPPeeringPolicy v2alpha1 BGP template with the
v2 CiliumBGPClusterConfig, CiliumBGPPeerConfig, CiliumBGPAdvertisement,
and CiliumLoadBalancerIPPool resource set
- Move Cilium load balancer Helm keys from bpf.loadBalancer to the valid
top-level loadBalancer path
- Add preflight schema validation and remove the deprecated policy after
the v2 objects are accepted
- Wait for cilium status after installation
- Pin kube-vip RBAC in a repository template instead of fetching a
mutable URL, and include EndpointSlice permissions
- Fix the kube-vip bgppeers format to address:ASN comma-separated peers
- Fail clearly when the MetalLB speaker tag replacement does not apply
- Drop the obsolete MetalLB webhook service name version branch
* test(molecule): verify upgraded cluster components
- Assert every node reports the expected K3s kubelet version
- Verify the active CNI (Flannel / Calico / Cilium) is Ready and runs
the expected image tag, including Calico TigeraStatus Available
- Verify the active load balancer (MetalLB / kube-vip) runs the expected
image tags and that MetalLB is absent when kube-vip is active
- Assert no Flannel DaemonSet remains when Calico or Cilium is enabled
- Assert the example LoadBalancer address falls inside the configured
pool range
- Add a manifest-only Cilium BGP regression test that renders the v2
template with zero, one, and multiple neighbors and rejects any v2alpha1
or CiliumBGPPeeringPolicy output
* fix(dependencies): correct dependency version pins
- Set the sample kube-vip image to v1.2.2 and repair the damaged comment
- Pin the kube-vip cloud provider default to v0.0.12 in the task URL
- Set the MetalLB controller argument-spec default to v0.16.0
- Restore the MetalLB available timeout default to 240s
* docs(dependencies): document current cluster versions
- Update kube-vip, kube-vip cloud provider, and MetalLB defaults
- Add cilium_tag and cilium_cli_tag rows
- Explain that MetalLB v0.16.0 is the application image target even though
a newer chart-only tag (metallb-chart-0.16.1) exists
- Add an existing-cluster upgrade warning covering the K3s etcd 3.5.26
bridge and one-minor-at-a-time rule, consecutive Cilium minor upgrades,
Calico v3 resource UID handling, and MetalLB app vs chart tags
* fix(dependencies): address PR review findings
- Read the MetalLB speaker tag check from the managed host with slurp
instead of a controller-side file lookup, and match the full image
reference
- Restore the tigera-operator namespace on the Calico operator Deployment
wait while keeping the managed CRD waits cluster-scoped
- Make Molecule verify inputs durable and scenario-specific via a
per-scenario verify-vars.yml, driven by explicit verify_cni/verify_lb
values instead of non-persisted converge facts
- Rename the kube-vip multi-peer BGP env var from bgppeers to bgp_peers
and vip_cidr to vip_subnet so v1.2.2 actually reads them
- Map the legacy Cilium routed mode to tunnel and stop passing the alias
directly to the chart
- Use return-code based failed_when on apply and preflight commands so
non-error failures are no longer treated as success
- Clarify the sequential K3s upgrade path and backups in the README
- Add kube-vip and MetalLB regression tests and a Cilium mode mapping unit
* fix(dependencies): resolve re-review findings
- correct the Calico TigeraStatus resource kind\n- document tunnel as the supported Cilium routing mode\n- validate load balancer addresses across range and CIDR pools
* fix(molecule): verify embedded flannel instead of a flannel DaemonSet
- K3s 1.36 runs flannel embedded in the k3s agent rather than as a
kube-flannel-ds DaemonSet, so the flannel verifier queried a workload
that no longer exists and failed the verify step
- For the flannel scenarios, assert every node is Ready and that neither
the Calico nor the Cilium namespace exists
- Drop the now-invalid kube-flannel-ds DaemonSet assertion
* fix(molecule): wait for the LoadBalancer address before asserting reachability
- The nginx LoadBalancer service had no ingress address when the
reachability assertion ran, so status.loadBalancer.ingress[0].ip was
undefined and the ipwrap filter failed during verify
- Poll the service until MetalLB or kube-vip assigns an external IP
- Record the assigned address once and reuse it for the reachability probe
and the pool membership checks
* fix(ci): harden calico apiserver wait and extend molecule job timeout
- Bump calico system resources wait retries 30->60 and delay 7->10 so the
slow-to-reconcile calico-apiserver deployment has enough time under nested-virt
- Raise the molecule step timeout-minutes from 90 to 150 to accommodate
contended 5-node scenarios (cilium, kube-vip) that were hitting the 90-min cap
* fix(calico): treat optional API server as best-effort on converge
- The Calico API server (calico-apiserver) is an optional add-on for managing
Calico policy through the projectcalico.org/v3 Kubernetes API; it is not
required for Calico CNI data plane operation
- With Calico v3.32.1 on K3s 1.36 the tigera-operator never provisions the
calico-apiserver namespace, causing the converge wait to fail deterministically
- Keep the strict wait for core Calico components (typha, kube-controllers,
calico-node, csi-node-driver) and make the API server wait tolerate failure
- Restrict the TigeraStatus Available check to the calico status, matching the
upstream v3.32.1 K3s quickstart which validates without the API server
