      To deploy GooseFS using TKE, the open source Fluid component is required, which is available in the TKE application market. You can deploy as follows:
      1. Use Fluid helm chart to deploy controllers.
      2. Use kubectl to create the dataset and GooseFS runtime.

      Preparations

      1. Have a Tencent Cloud TKE cluster.
      2. Have installed kubectl of v1.18 or a later version.

      Installation

      1. Find Fluid from the TKE Application Market.
      2. Install Fluid controllers.
      3. Check the controllers. You can click Cluster in the left sidebar and find the desired cluster. If there are two controllers, Fluid has been installed successfully.

      Operation Example

      1. Authorize cluster access

      [root@master01 run]# export KUBECONFIG=xxx/cls-xxx-config (Download the cluster credential to a directory from the TKE console.)
      Note:
      You need to grant the cluster’s API Server access to the public network.

      2. Create a UFS dataset (using COS as an example)

      Create secret.yaml for encryption. The template is as follows:
      apiVersion: v1
      kind: Secret
      metadata:
        name: mysecret
      stringData:
        fs.cosn.userinfo.secretKey: xxx
        fs.cosn.userinfo.secretId:xxx
      Create secret:
      [root@master01 ~]# kubectl apply  -f secret.yaml
      secret/mysecret created
      dataset.yaml template:
      apiVersion: data.fluid.io/v1alpha1
      kind: Dataset
      metadata:
        name: slice1
      spec:
        mounts:
        - mountPoint: cosn://{your bucket}
          name: slice1
          options:
            fs.cosn.bucket.region: ap-beijing
            fs.cosn.impl: org.apache.hadoop.fs.CosFileSystem
            fs.AbstractFileSystem.cosn.impl: org.apache.hadoop.fs.CosN
            fs.cosn.userinfo.appid: "${your appid}"
          encryptOptions:
            - name: fs.cosn.userinfo.secretKey
              valueFrom:
                secretKeyRef:
                  name: mysecret
                  key: fs.cosn.userinfo.secretKey
            - name: fs.cosn.userinfo.secretId
              valueFrom:
                secretKeyRef:
                  name: mysecret
                  key: fs.cosn.userinfo.secretId
      Create a dataset:
      [root@master01 run]# kubectl apply -f dataset.yaml 
      dataset.data.fluid.io/slice1 created
      Query the dataset status (NotBond):
      [root@master01 run]# kubectl get dataset
      NAME     UFS TOTAL SIZE   CACHED   CACHE CAPACITY   CACHED PERCENTAGE   PHASE      AGE
      slice1 
                                                                       NotBound   11s

      3. Create runtime

      untime.yaml template:
      apiVersion: data.fluid.io/v1alpha1
      kind: GooseFSRuntime
      metadata:
        name: slice1
      spec:
        replicas: 1
        data:
          replicas: 1
        goosefsVersion:
          imagePullPolicy: Always
          image: ${img_uri}
          imageTag: ${tag}
        tieredstore:
          levels:
            - mediumtype: MEM
              path: /dev/shm
              quota: 1Gi
              high: "0.95"
              low: "0.7"
        properties:
          # goosefs user
          goosefs.user.file.writetype.default: MUST_CACHE
        master:
          replicas: 1
          journal:
            volumeType: hostpath
          jvmOptions:
            - "-Xmx40G"
            - "-XX:+UnlockExperimentalVMOptions"
            - "-XX:ActiveProcessorCount=8"
        worker:
          jvmOptions:
            - "-Xmx12G"
            - "-XX:+UnlockExperimentalVMOptions"
            - "-XX:MaxDirectMemorySize=32g"
            - "-XX:ActiveProcessorCount=8"
          resources:
            limits:
              cpu: 8
        fuse:
          imagePullPolicy: Always
          image: ${fuse_uri}
          imageTag: ${tag_num}
          env:
            MAX_IDLE_THREADS: "32"
          jvmOptions:

            - "-XX:MaxDirectMemorySize=32g"
            - "-XX:+UnlockExperimentalVMOptions"
            - "-XX:ActiveProcessorCount=24"
          resources:
            limits:
              cpu: 16
          args:
            - fuse
            - --fuse-opts=kernel_cache,ro,max_read=131072,attr_timeout=7200,entry_timeout=7200,nonempty
      Create runtime:
      [root@master01 run]# kubectl apply -f runtime.yaml 
      goosefsruntime.data.fluid.io/slice1 created
      Check the GooseFS component status:
      [root@master01 run]# kubectl get pods
      NAME                  READY   STATUS    RESTARTS   AGE
      slice1-fuse-xsvwj     1/1     Running   0          37s
      slice1-master-0       2/2     Running   0          118s
      slice1-worker-fzpdw   2/2     Running   0          37s

      4. Load data

      dataload.yaml data loading component:
      apiVersion: data.fluid.io/v1alpha1
      kind: DataLoad
      metadata:
        name: slice1-dataload
      spec:
        dataset:
          name: slice1
          namespace: default
      The dataset status is “Bond”, and 0% is cached.
      [root@master01 run]# kubectl get dataset
      NAME     UFS TOTAL SIZE   CACHED   CACHE CAPACITY   CACHED PERCENTAGE   PHASE   AGE
      slice1   97.67MiB         0.00B    4.00GiB          0.0%                Bound   31m
      Start loading data:
      [root@master01 run]# kubectl apply -f dataload.yaml 
      dataload.data.fluid.io/slice1-dataload created
      View data loading progress:
      [root@master01 run]# kubectl get dataset --watch
      NAME     UFS TOTAL SIZE   CACHED     CACHE CAPACITY   CACHED PERCENTAGE   PHASE   AGE
      slice1   97.67MiB         52.86MiB   4.00GiB          54.1%               Bound   39m

      100% of the data is cached:
      [root@master01 run]# kubectl get dataset --watch
      NAME     UFS TOTAL SIZE   CACHED     CACHE CAPACITY   CACHED PERCENTAGE   PHASE   AGE
      slice1   97.67MiB         97.67MiB   4.00GiB          100.0%              Bound   44m

      5. View data

      [root@master01 run]# kubectl get pods
      NAME                               READY   STATUS      RESTARTS   AGE

      Go to the GooseFS master container:
      [root@master01 run]# kubectl exec -it slice1-master-0 -- /bin/bash
      Defaulting container name to goosefs-master.
      List GooseFS directories:
