问题可能是本地卷

volumes:
  katana-static:
    driver: local-persist
    driver_opts:
      mountpoint: /data/local-persist/data/warrior/katana-static
  katana-wapps:
    driver: local-persist
    driver_opts:
      mountpoint: /data/local-persist/data/warrior/wapps
  katana-wui:
    driver: local-persist
    driver_opts:
      mountpoint: /data/local-persist/data/warrior/wui
  nginx-secrets:
    driver: local-persist
    driver_opts:
      mountpoint: /data/local-persist/data/warrior/nginx-secrets
  katana-secrets:
    driver: local-persist
    driver_opts:
      mountpoint: /data/local-persist/data/warrior/katana-secrets

本地卷在OpenShift中不工作。我建议您使用'kompose convert'命令将docker-compose转换为kubernetes YAMLs。

然后回顾和更新pvc和PV的。然后最后一个一个地部署资源
