I made one k3s-master
on ubuntu 20 and one k3s-agent
on another ubuntu 20. I have both system connected to same network.I have docker image on k3s-agent, I can able to run the container on k3s-agent.I created one cluster and k3s-agent and k3s-master both are connected to cluster. I checked with kubectl get nodes
command on master and I can see agent and master are listed.
I need help on following points. I want to run docker image on k3s-agent from k3s-master. Is there any way to run docker image on agent from master ?
I came to know that I can make pod and using pod I can do that. but pod is not working out.
There are two things we can do.
nodeName
,Just mention the nodeName: mynode1
in yaml file.
taints and toleration
We can set Taints and Toleration
inside pod`s yaml file. Example below.
set Taints to node like this
kubectl taint nodes mynode1 app=Device:NoSchedule
and we can toleration in yaml file as below.
apiVersion: v1
kind: Pod
metadata:
name: scriptpod
spec:
containers:
- name: scriptdo
image: scriptdo
imagePullPolicy: Always
nodeName: mynode1
restartPolicy: Always
tolerations:
- key: "app"
operator: "Equal"
value: "Device"
effect: "NoSchedule"
Document for taints and toleration
Note:- I set nodeName
and taints and toleration
both, cause nodeName
not worked in rare case.
