t
that is how it works. You need to then run a 
kubectl exec
to get into a pod.
f
Its shell form the node man
Usually it gives shell form pod
Not node
t
rancher gives a shell in the pod. Harvester is the node. From that shell you can shell into a pod if you want. You can also download the kubeconfig to connect to the “cluster”.
f
Bro i have other deployments in harvester
And it gives me the shell into the pod i select
t
are you using the hidden rancher gui view of harvester? your image was not clear
f
In theory u are not supposed to use harvester node shells
No
t
how is rancher and harvester setup?
f
I have a 3 node harvester cluster And an other 3 node rke2 where i have rancher
t
did you add harvester as a cluster or as harvester itself?
f
I added as a hypervisro
t
ok.. let me test. what versions of Rancher and harvester are you running?
f
I think 4.0 and 10.3 but give me 5 min to check
t
the latest is harv - 1.4.1 and rancher 2.10.2 https://dzver.rfed.io/
f
Rancher v2.10.1
Harvester v1.4.0
t
ok cool, my cluster is coming up now.
f
The whole idea was that we wanted to have a DDNS so we can provision other clusters in harvester using rancher and we had 4 servers so we decided to do so : server 1 : 4 vms rke2 and install rancher server 2: harvester node 1 server 3: harvester node 2 server 4: harverster node 3 and we are trying to deploy the DDNS and KeaDhcp in harvester cluster as k8s deploymet
if u have any other solutions to this we would appreciate it
t

https://youtu.be/9y37tuMBSUg▾

a quick vid I put together for ya.
better vid :

https://www.youtube.com/watch?v=GPXkoi6ueVA&amp;t=0s▾

f
Yes but if u pres create cluster when the nodes spin up they need ddns
To be able to talk to each other
Still lets not deviate from the main issue
t
what is the big picture?
what are you trying to do? like connect App A on harvester to appB on rancher?
f
From rancher spin up multiple rke2 clusters
And the clusters are vms in harvester
t
ok the one video shows how to do that.
Oh and that is where the shell issue comes into play?
f
No the shell is when we deploy ddns
Bind9
t
ah. big picture, I would use an external DNS to manage everything.
f
Ye but i cant use that
Thats why im in this loop
And still
The node shell issue conserns
At first looked as RCE(remot code execution)
But i wanted to clarify
t
let me rebuild to see if I can recreate the shell issue.
👍 1
f
Let me know if u need anything form me
t
$1mill! 😄
😁 1
f
I wish i had them
t
ok, have the env up. did you hit the 
~
key or click the 3 dots and select shell?
f
3dots
t
and just to confirm you named you cluster harvester?
f
Yes harvester-farm
Let me show u
t
want to jump on zoom?
f
yes
google meet better
t
DM a link
f
Hi @thousands-advantage-10804 I upgraded the servers to latest version also fixed some hdd drivers and i will test this weekend with the fresh installed harvester
Just to update on the topic
