Volcano install failed

[hzxuzhonghu]

Is this a BUG REPORT or FEATURE REQUEST?:

Uncomment only one, leave it on its own line:

/kind bug

What happened:

install volcano as readme, but i meet the following error.

$ helm install volcano/volcano --namespace kube-system --name volcano
Error: namespaces "kube-system" is forbidden: User "system:serviceaccount:kube-system:default" cannot get resource "namespaces" in API group "" in the namespace "kube-system

What you expected to happen:

1. install successfully

2. allow user to set volcano flags

3. provide a simple install yaml

How to reproduce it (as minimally and precisely as possible):

install volcano following https://github.com/volcano-sh/volcano/blob/master/README.md

Anything else we need to know?:

my kubernetes cluster is created by kind

Environment:

• Volcano Version:
• Kubernetes version (use kubectl version):
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:

I have opened #325 to track contributor experience improvement stuff.

We need a more simple way to install, one command kubectl apply -f xxx.yaml.

Helm is complicated, it requires users to install helm and tiller first.

what is the version of helm ? Tiller of helm v3 is gone, how about maintaining xxx.yaml and helm repo.

With the current master branch code I am getting this error for jobs.batch.volcano.sh

kubectl create -f batch_v1alpha1_job.yaml 
The CustomResourceDefinition "jobs.batch.volcano.sh" is invalid:

@asifdxtreme What's your k8s version?

[asifdxtreme]

@asifdxtreme What's your k8s version?

kubectl version --short
Client Version: v1.15.0
Server Version: v1.10.0

Works well on my environment:

 ⚡ root@husheng: kb version --short
Client Version: v1.15.0
Server Version: v1.15.0

Seems RBAC problem ?

@TommyLike , @hzxuzhonghu , when can we get this done?

@TommyLike , @hzxuzhonghu , when can we get this done?

@k82cn , For this issue itself. it's the RBAC issue which needs us to install tiller with enough rights to handle resource, it's something like:

kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller

That's why @hzxuzhonghu is asking us we need more document to notify that.
But for the issue which @asifdxtreme or the volcano user @Swati Agrawal, we need more detail to find out the root cause. It can be the kubernetes version mismatch, helm binary version requirement or something else. Therefore we may need the helm installing output. tiller log or even kubeapi server log to locate it I guess.

With the current master branch code I am getting this error for jobs.batch.volcano.sh

kubectl create -f batch_v1alpha1_job.yaml 
The CustomResourceDefinition "jobs.batch.volcano.sh" is invalid:

This a similar issue to this OpenAPI issue kubernetes/apiextensions-apiserver#26.

We used to use kind 0.2.0 to running our E2E tests, which means the oldest version of kubernetes that have been tested should be 1.13.4. https://github.com/kubernetes-sigs/kind/releases/tag/0.2.0

@hzxuzhonghu please try the latest installation guide in master branch.
