warning about missing tc package #9242

Open rptaylor opened 2 years ago

rptaylor commented 2 years ago

Environment: Almalinux 8

Kubespray version (commit) (git rev-parse --short HEAD): 2.18.2

Kubespray invokes kubeadm like this, it generates a warning:

# /usr/local/bin/kubeadm join --config /etc/kubernetes/kubeadm-controlplane.yaml --ignore-preflight-errors=all --skip-phases=
[preflight] Running pre-flight checks
    [WARNING FileExisting-tc]: tc not found in system path

On EL8-based systems this should be fixed via sudo dnf install iproute-tc

It looks like #4212 was closed without fixing the issue in Kubespray.

Hum 2.18 is not supported anymore, does this still happens:

  1. On master ?
  2. On supported releases branches (2.24, 2.23, 2.22) ?
rptaylor commented 7 months ago

The newest version I am using at the moment is kubespray 2.20 (k8s 1.24) and it still happens:

$ sudo /usr/local/bin/kubeadm join --config /etc/kubernetes/kubeadm-controlplane.yaml --ignore-preflight-errors=all --skip-phases=

/triage needs-information (-> until we know if this still happens on supported versions)
