rbac配置如下:
代码语言:javascript复制apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
namespace: default
name: pod-reader
rules:
- apiGroups: [""] # "" indicates the core API group
resources: ["pods"]
verbs: ["get", "watch", "list"]
---
apiVersion: rbac.authorization.k8s.io/v1
# This role binding allows "viewer" to read pods in the "default" namespace.
# You need to already have a Role named "pod-reader" in that namespace.
kind: RoleBinding
metadata:
name: read-pods
namespace: default
subjects:
# You can specify more than one "subject"
- kind: User
name: viewer # "name" is case sensitive
apiGroup: rbac.authorization.k8s.io
roleRef:
# "roleRef" specifies the binding to a Role / ClusterRole
kind: Role #this must be Role or ClusterRole
name: pod-reader # this must match the name of the Role or ClusterRole you wish to bind to
apiGroup: rbac.authorization.k8s.io
这里给viewer用户查看default namespace pod的权限,如下:
代码语言:javascript复制$ oc apply -f pod-reader-role.yaml
$ oc get users
NAME UID FULL NAME IDENTITIES
admin 83ea55bf-b33c-4df5-8d90-b74f5df752d8 my_htpasswd_provider:admin
viewer 0d0a3d16-b9ce-425a-87f3-1874468a9ad8 my_htpasswd_provider:viewer
$ oc login -u viewer -p admin
Login successful.
You don't have any projects. You can try to create a new project, by running
oc new-project <projectname>
$ oc get po -n default
No resources found in default namespace.
$ oc get po -n openshift-config
Error from server (Forbidden): pods is forbidden: User "viewer" cannot list resource "pods" in API group "" in the namespace "openshift-config"
可以看到,当使用viewer用户登录ocp后,只能查看default namespace中的pod,如果查询其他namespace的pod会被禁止。
