您很可能没有正确配置 PVC，并且容器正在尝试装载声明，但声明未绑定到 PV。
请确保 taiga-static-data 和 taiga-media-data pvc 绑定到它们各自的 pv。
问题是持久卷未绑定到 pod，因此 pod 无法启动。确保配置存储并创建持久卷。

根据您的来源 docker 规范，您可以将 persistentVolumeClaim 替换为 emptyDir。
volumes:
- name: taiga-gateway-claim0
emptyDir: {}
- name: taiga-static-data
emptyDir: {}
- name: taiga-media-data
emptyDir: {}
或者如果你想保留你的数据（继续使用persistentVolumeClaim），你应该先创建 PVC：
apiVersion: v1
kind: PersistentVolumeClaim
