Kind: RHEL 7.6: cluster creation fails for Kubernetes < 1.14

[Hendrik-H]

What happened:
I'm trying to create clusters using kind 0.5.1 and different node images, using the list from https://github.com/kubernetes-sigs/kind/releases/tag/v0.5.0, as there is none for 0.5.1. This works fine for kindest/node:v1.15.3@sha256:27e388752544890482a86b90d8ac50fcfa63a2e8656a96ec5337b902ec8e5157 and kindest/node:v1.14.6@sha256:464a43f5cf6ad442f100b0ca881a3acae37af069d5f96849c1d06ced2870888d but fails for the other images.

The output of the command line is:

> kind create cluster --name kind-11 --image kindest/node:v1.11.10@sha256:bb22258625199ba5e47fb17a8a8a7601e536cd03456b42c1ee32672302b1f909 --retain

 ✓ Preparing nodes 📦 
 ✓ Creating kubeadm config 📜 
 ✗ Starting control-plane 🕹️ 
Error: failed to create cluster: failed to init node with kubeadm: exit status 1

What you expected to happen:
That the clusters get created cleanly.

How to reproduce it (as minimally and precisely as possible):

kind create cluster --name kind-11 --image kindest/node:v1.11.10@sha256:bb22258625199ba5e47fb17a8a8a7601e536cd03456b42c1ee32672302b1f909 --retain
kind create cluster --name kind-12 --image kindest/node:v1.12.10@sha256:e43003c6714cc5a9ba7cf1137df3a3b52ada5c3f2c77f8c94a4d73c82b64f6f3 --retain
kind create cluster --name kind-13 --image kindest/node:v1.13.10@sha256:2f5f882a6d0527a2284d29042f3a6a07402e1699d792d0d5a9b9a48ef155fa2a --retain

Anything else we need to know?:
The logs for a failed cluster creation:
kind-13.zip

Environment:

• kind version: (use kind version): v0.5.1
• Kubernetes version: (use kubectl version): v1.15.3
• Docker version: (use docker info): 17.05.0-ce
• OS (e.g. from /etc/os-release): RHEL 7.6

/assign

FWIW on a linux box (~debian testing):

$ kind create cluster --name kind-11 --image kindest/node:v1.11.10@sha256:bb22258625199ba5e47fb17a8a8a7601e536cd03456b42c1ee32672302b1f909 --retain
Creating cluster "kind-11" ...
 ✓ Ensuring node image (kindest/node:v1.11.10) 🖼
 ✓ Preparing nodes 📦 
 ✓ Creating kubeadm config 📜 
 ✓ Starting control-plane 🕹️ 
 ✓ Installing CNI 🔌 
 ✓ Installing StorageClass 💾 
Cluster creation complete. You can now use the cluster with:

export KUBECONFIG="$(kind get kubeconfig-path --name="kind-11")"
kubectl cluster-info

this looks like https://github.com/kubernetes/kubernetes/issues/43856 (from the logs you uploaded), I'm not sure what changed in 1.14+ yet though.

[Hendrik-H]

same result on RHEL 7.7

@Hendrik-H have you tried using a newer version of docker?
from the logs seems you are using Server Version: 17.05.0-ce

[Hendrik-H]

no, I can only test with the version that I get with RHEL

[BenTheElder]

Kubernetes 1.13 is out of support upstream now, and I'm pretty sure this docker version isn't supported upstream either. I don't have RHEL, but hopefully the next RHEL release will ship something newer or we'll figure out podman..

Given that upstream supported Kubernetes versions work, I don't think we're likely to pursue this versus other work.
