Rke: --ssh-agent-auth broke between v0.1.8-rc9 and v0.1.8-rc10

Created on 23 Jul 2018 · 4Comments · Source: rancher/rke

Synopsis:
It looks like --ssh-agent-auth broke somewhere between v0.1.8-rc9 and v0.1.8-rc10. Below, I've got the key loaded in my agent, and everything works as expected in rc9. Bump to rc10 and it starts complaining about a file it shouldn't need to check.

RKE version:
v0.1.8-rc10 and up

Docker version: (docker version,docker info preferred)
n/a

Operating system and kernel: (cat /etc/os-release, uname -r preferred)
macOS Sierra 10.12.6 (16G1212)

Type/provider of hosts: (VirtualBox/Bare-metal/AWS/GCE/DO)
ubuntu 16.04 hosts

cluster.yml file:
n/a

Steps to Reproduce:

$ ~/bin/rke_darwin-amd64-v0.1.8-rc10 up --config infra-chd-1/cluster.yml --ssh-agent-auth

v0.1.10-rc2

--ssh-agent-auth works correctly (with key loaded into ssh-agent), and cluster is brought up successfully.

I had the same problem. I solved it by creating the file id_rsa.

touch ~/.ssh/id_rsa

The same is a temporary arrangement. They should correct the problem, if in the configuration there is 'ssh_agent_auth: true' you must omit the file id_rsa.
