Installing K3s v1.24.3+k3s1 on a RHEL 7.9 system fails:
- As the first master node, all pods remain in
- As an additional master node the traefik pod remains in
The following event probably indicates what the problem is:
Warning FailedCreatePodSandBox pod/metrics-server-668d979685-4dzkm Failed to create pod sandbox: rpc error: code = Unknown desc = failed to create containerd task: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: open /proc/sys/net/ipv4/ip_unprivileged_port_start: no such file or directory: unknown
According to the information I could find about this error, the
ip_unprivileged_port_start entry in
/proc/sys/net/ipv4/ only exists in Linux kernel 4.4 and newer, so it seems that the latest Red Hat 7 release (7.9) is not supported anymore. Or am I missing something?
If this is true, Debian 9 (stretch) is also not supported anymore as it is also missing this entry.
