juicefs csi 集成试用

主要是一个试用，对于k8s 使用了minikube

minikube 安装

这个直接可以参考官方文档 (注意可能需要合理上网)

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-darwin-amd64

sudo install minikube-darwin-amd64 /usr/local/bin/minikube

minikube start

部署juicefs csi driver

官方提供了部署文档参考

• 部署csi driver

kubectl apply -f https://raw.githubusercontent.com/juicedata/juicefs-csi-driver/master/deploy/k8s.yaml

• 动态配置
  secret

 

kubectl -n default create secret generic juicefs-secret \

    --from-literal=name=mydemoapp \

    --from-literal=metaurl=redis://@<redis>:6379 \

    --from-literal=storage=minio \

    --from-literal=bucket=http://<endpoint>/juicefsapp \

    --from-literal=access-key=<key>\

    --from-literal=secret-key=<secret>

• 创建存储类以及pv&pvc&pod

apiVersion: storage.k8s.io/v1

kind: StorageClass

metadata:

  name: juicefs-sc

  namespace: default

provisioner: csi.juicefs.com

parameters:

  csi.storage.k8s.io/provisioner-secret-name: juicefs-secret

  csi.storage.k8s.io/provisioner-secret-namespace: default

  csi.storage.k8s.io/node-publish-secret-name: juicefs-secret

  csi.storage.k8s.io/node-publish-secret-namespace: default

---

apiVersion: v1

kind: PersistentVolumeClaim

metadata:

  name: juicefs-pvc

  namespace: default

spec:

  accessModes:

  - ReadWriteMany

  resources:

    requests:

      storage: 10Pi

  storageClassName: juicefs-sc

---

apiVersion: v1

kind: Pod

metadata:

  name: juicefs-app

  namespace: default

spec:

  containers:

  - args:

    - -c

    - while true; do echo $(date -u) >> /data/out.txt; sleep 5; done

    command:

    - /bin/sh

    image: centos

    name: app

    volumeMounts:

    - mountPath: /data

      name: juicefs-pv

  volumes:

  - name: juicefs-pv

    persistentVolumeClaim:

      claimName: juicefs-pvc

• 效果

minikube dashboard

说明

官方提供了一些最佳实践很值得学习下，同时源码也是值得学习的
