我使用 nginx ingress 作為負載平衡器部署了 bitnami/wordpress helm這裡。一切工作正常,但某些 pod 是透過自動縮放手動或自動建立時出現問題。其中一些(不是全部)始終具有“ContainerCreating”狀態,日誌如下所示:
Normal Scheduled 33m default-scheduler Successfully assigned default/wordpress-69c8f65d96-wnkfv to main-node-d29388
Warning FailedMount 4m28s (x6 over 29m) kubelet Unable to attach or mount volumes: unmounted volumes=[wordpress-data], unattached volumes=[default-token-s4gdj wordpress-data]: timed out waiting for the condition
Warning FailedMount 0s (x9 over 31m) kubelet Unable to attach or mount volumes: unmounted volumes=[wordpress-data], unattached volumes=[wordpress-data default-token-s4gdj]: timed out waiting for the condition
我部署了 bitnami/wordpress,然後使用以下設定進行升級:
helm install wordpress bitnami/wordpress --set service.type=ClusterIP --set ingress.enabled=true --set ingress.certManager=true --set ingress.annotations."kubernetes\.io/ingress\.class"=nginx --set ingress.annotations."cert-manager\.io/cluster-issuer"=letsencrypt-prod --set ingress.hostname=DOMAIN.com --set ingress.extraTls[0].hosts[0]=DOMAIN.com --set ingress.extraTls[0].secretName=wordpress.local-tls --set wordpressPassword=PASSWORD --set autoscaling.enabled=true --set autoscaling.minReplicas=1 autoscaling.maxReplicas=30
kubectl get pods 看起來像這樣
ingress-nginx-ingress-controller-84bff86888-f4tpb 1/1 Running 0 2d3h
ingress-nginx-ingress-controller-default-backend-c5b786dbbqw5xz 1/1 Running 0 2d3h

如何避免新 Pod 出現此問題並使它們啟動?

用戶@Juan 是對的。我採用了類似的方法,我使用 helm 創建了其他 POD 來創建存儲,並將其在 WordPress 部署中設置為持久性。這裡對其進行了描述:https://docs.bitnami.com/tutorials/deploy-applications-nfs-kubernetes/
