Hi,
It seems that I cannot add any hosts using Custom option. This is the setup:
I have a host called andonmaster and it’s running the rancher. Then I have one host named dockerregistry which I want to add to rancher. But this simple job seems to be too hard for me or for our env…
We have our own cloud where we must use domain names. Is that somehow the factor? IMO the iptables are ok in both hosts…
