我正在尝试在全新的 k8s 集群中使用操作员创建普罗米修斯我使用以下文件,
- 我正在创建一个命名空间监控
- 应用这个文件,它工作正常
apiVersion: apps/v1beta2
kind: Deployment
metadata:
labels:
k8s-app: prometheus-operator
name: prometheus-operator
namespace: monitoring
spec:
replicas: 2
selector:
matchLabels:
k8s-app: prometheus-operator
template:
metadata:
labels:
k8s-app: prometheus-operator
spec:
priorityClassName: "operator-critical"
tolerations:
- key: "WorkGroup"
operator: "Equal"
value: "operator"
effect: "NoSchedule"
- key: "WorkGroup"
operator: "Equal"
value: "operator"
effect: "NoExecute"
containers:
- args:
- --kubelet-service=kube-system/kubelet
- --logtostderr=true
- --config-reloader-image=quay.io/coreos/configmap-reload:v0.0.1
- --prometheus-config-reloader=quay.io/coreos/prometheus-config-reloader:v0.29.0
image: quay.io/coreos/prometheus-operator:v0.29.0
name: prometheus-operator
ports:
- containerPort: 8080
name: http
securityContext:
allowPrivilegeEscalation: false
readOnlyRootFilesystem: true
nodeSelector:
serviceAccountName: prometheus-operator
现在我想应用这个文件(CRD)
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
name: prometheus
namespace: monitoring
labels:
prometheus: prometheus
spec:
replica: 1
priorityClassName: "operator-critical"
serviceAccountName: prometheus
nodeSelector:
worker.garden.sapcloud.io/group: operator
serviceMonitorNamespaceSelector: {}
serviceMonitorSelector:
matchLabels:
role: observeable
tolerations:
- key: "WorkGroup"
operator: "Equal"
value: "operator"
effect: "NoSchedule"
- key: "WorkGroup"
operator: "Equal"
value: "operator"
effect: "NoExecute"
在我创建那些 CRD 之前

Pod 无法启动的问题(0/2),见下图。可能是什么问题呢?请指教
更新
当我参加舞会运营商的活动时,我看到以下错误creating: pods "prometheus-operator-6944778645-" is forbidden: no PriorityClass with name operator-critical was found replicaset-controller
,知道吗?
