库伯内特斯吊舱卡在集装箱内

kompose google-cloud-platform kubernetes docker

我正在尝试部署这个 docker-compose GCP kubernetes上的应用程序。

我用过 Kompose 生成我的kubernetes部署文件。所有的吊舱都光着两个。然而,除了这一点,它们没有显示任何错误。

无法附加或装载卷:已卸载卷=[taiga静态数据taiga媒体数据],未连接卷=[kube-api-access-9c74v taiga-gateway-claim0 taiga静态数据 taiga media data(泰加媒体数据)]:等待条件时超时

这是一个安装卷的问题,我确信,从之前的一个错误来看 taiga-back 和 taiga-db 共享一卷。

根据您的原始docker规格,您可以替换 persistentVolumeClaim 具有 emptyDir .

volumes:
- name: taiga-gateway-claim0
  emptyDir: {}
- name: taiga-static-data
  emptyDir: {}
- name: taiga-media-data
  emptyDir: {}

或者,如果您想保留数据(继续使用 持续体积瞄准 ),您应该首先创建PVC:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: taiga-gateway-claim0
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: taiga-static-data
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: taiga-media-data
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi
---
apiVersion: apps/v1
kind: Deployment
metadata:
  ...

上述规范将使用服务器上的默认StorageClass为pod动态提供3个持久卷 GKE 簇

Blender Fox 2 年前

您很可能没有正确配置PVC,容器正在尝试装载声明,但声明未绑定到PV。

Manmohan Mittal 2 年前

请确保taiga静态数据和;泰加媒体数据PVC绑定到各自的pvs。

P Ekambaram 2 年前

问题是持久卷未绑定到pod,因此pod无法启动。确保已配置存储并创建了持久卷。
