我正在尝试在 pod 中启动 prometheus,并在 k8s 中使用持久卷。

当我启动 pod 时,我看到:

  level=info ts=2021-09-12T13:58:13.120Z caller=main.go:390 msg="No time or size retention was set so using the default time retention" duration=15d

panic: Unable to create mmap-ed active query log

我发现了同样的问题,但它在 docker 中 Error opening query log file

我的 pod 配置:

apiVersion: apps/v1
kind: Deployment
metadata:
name: prometheus-deployment
namespace: default
labels:
app: prometheus-server
spec:
replicas: 1
selector:
matchLabels:
app: prometheus-server
template:
spec:
containers:
- name: prometheus
image: prom/prometheus:latest
imagePullPolicy: "IfNotPresent"
args:
- "--config.file=/etc/prometheus/prometheus.yml"
- "--storage.tsdb.path=/prometheus/"
ports:
- containerPort: 9090
volumeMounts:
- name: prometheus-config-volume
mountPath: /etc/prometheus/
- name: prometheus-storage-volume
mountPath: /prometheus/
volumes:
- name: prometheus-storage-volume
persistentVolumeClaim:
claimName: prometheus-pv-claim
- name: prometheus-config-volume
configMap:
defaultMode: 420
name: prometheus-server-conf

最佳答案

我遇到了同样的问题。您需要在规范中提供安全上下文。

securityContext:
fsGroup: 65534
runAsGroup: 65534
runAsNonRoot: true
runAsUser: 65534
