I want to convert below line to run as a bash script so that i can call it using jenkins job.
kubectl create -f tiller-sa-crb.yamlThe tiller-sa-crb.yaml is below. How can i convert my above command in bash script. such that my jenkins job calls ./tiller-sa-crb.sh and it does all below. Basically, my end goal is to have a pure shell script and invoke that on jenkins job.
apiVersion: v1
kind: ServiceAccount
metadata:
name: tiller
namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
name: tiller
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: tiller
namespace: kube-systemYou can also make use of stdin to kubectl create command, like this:
#!/usr/bin/env bash
cat <<EOF | kubectl create -f -
apiVersion: v1

EOFFigured out how to use kubectl with parameters on command line to create service account and also to create rolebinding using the service account.
#!/bin/bash
#create SA account in one line in namespace kube-system
kubectl create serviceaccount tiller -n kube-system
#create cluster role binding in one line using above serviceaccount and in kube-system namespace
kubectl create clusterrolebinding crb-cluster-admin-test2 --
clusterrole=cluster-admin --serviceaccount=kube-system:tiller
