用于 Kubernetes 卷的 DigitalOcean 块存储

Question

我在 DigitalOcean 上有一个 K8S 集群运行ning。我在那里有一个 Postgresql 数据库运行ning，我想使用 DigitalOcean BlockStorage 创建一个卷，以供 Postgresql pod 用作卷。有没有关于如何做到这一点的例子？

如果无法使用 DigitalOcean 块存储，那么大多数公司如何运行他们的数据库持久存储？

Answer 1

暂无官方支持。您可以尝试 this github issue:

中某人的示例

Update: I finished writing a volume plugin for digitalocean. Attach/detach is working on my cluster. Looking for anyone willing to test this on their k8s digitalocean cluster. My branch is https://github.com/wardviaene/kubernetes/tree/do-volume

You can use the following spec in your pod yml:
spec:
  containers:
  - name: k8s-demo
    image: yourimage
    volumeMounts:
    - mountPath: /myvol
      name: myvolume
    ports:
    - containerPort: 3000
  volumes:
  - name: myvolume
    digitaloceanVolume:
      volumeID: mykubvolume
      fsType: ext4 Where mykubvolume is the volume created in DigitalOcean in the same region.
You will need to add create a config file:

[Global] apikey = do-api-key region = your-region and add these parameters to your kubernetes processes: --cloud-provider=digitalocean --cloud-config=/etc/cloud.config

I'm still waiting for an issue in the godo driver to be resolved, before I can submit a PR (digitalocean/godo#102)

Answer 2

我在这里 link 找到了关于 flexvolumes This mentions how you can customize to load vendor volumes. There is also a script on how to do this at script

Answer 3

DigitalOcean 块存储的容器存储接口 (CSI) 驱动程序。 https://github.com/digitalocean/csi-digitalocean 已使用 statefulset MySql 进行测试，工作正常
