为什么普罗米修斯操作员不能启动
为什么普罗米修斯操作员不能启动
提问于 2019-03-14 23:09:36
我正在尝试在fresh new k8s集群中使用operator创建普罗米修斯。我使用以下文件，
- 我正在创建一个名称空间监视
- 应用此文件，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现在我想要应用这个文件(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"在我创建这些CRD之前
https://github.com/coreos/prometheus-operator/tree/master/example/prometheus-operator-crd
pods无法启动 (0/2)的问题，请参见下图。可能的问题是什么？敬请指教
更新
当我转到prom操作符的事件时，我看到下面的错误creating: pods "prometheus-operator-6944778645-" is forbidden: no PriorityClass with name operator-critical was found replicaset-controller，你知道吗？

您正在尝试引用operator-critical priority class。优先级类别决定了pods的优先级及其资源分配。
要解决此问题，您可以删除这两个文件中的显式优先级类(priorityClassName: "operator-critical")或创建operator-critical类：
apiVersion: scheduling.k8s.io/v1beta1
kind: PriorityClass
metadata:
name: operator-critical
value: 1000000
globalDefault: false

Prometheus和警报管理器pod需要持久卷来存储数据。确保这些pv存在并绑定到相应的pods。或者，您可以使这些pod变得短暂。它应该是可行的
