Team, am learning and have no clue. could anyone explain please. my scenario is: Using KOPS tool, I deployed a cluster with 1Master, 2slaves, and 1LB. Now, i am trying to deploy ARGO workflow but don't know the process. will it install on Node or Master of the k8s cluster i built? how does it work?
Please assist. Basically, if anyone can describe the functional flow or steps of deploying ARGO work flow on kubernetes, it would be nice. first of all i need to understand where is it deployed on Master or Worker Node?
Usually, kops creates Kubernetes cluster with taints on a master node that prevent regular pods scheduling on it.
Although, there was an issues with some cluster network implementation, and sometimes you are getting a cluster without taints on the master.
You can change taints on the master node by running the following commands:
add taints (no pods on master):
kubectl taint node kube-master node-role.kubernetes.io/master:NoScheduleremove taints (allow to schedule pods on master):
kubectl taint nodes --all node-role.kubernetes.io/master-If you want to know whether the taints are applied to the master node of not, run the following command:
kubectl get node node-master --export -o yamlFind a spec: section. In case the taints are present, you should see something like this:
...
spec:
externalID: node-master
podCIDR: 192.168.0.0/24
taints:
- effect: NoSchedule
key: node-role.kubernetes.io/master
