使用 TKE 部署 GooseFS 需要借助 开源组件 Fluid 部署,TKE 应用市场已上架。部署包括两步: 2. 通过 kubectl 创建 Dataset 和 GooseFS runtime。
准备事项
1. 拥有腾讯云 TKE 集群。
2. 已安装 kubectl,版本 v1.18及以上。
安装步骤
2. 安装 Fluid Controller。
3. 检查 controller 组件。在左侧【集群】中找到对应集群,如果看到了两个 controller,则说明 fluid 组件安装成功。
操作演示
1. 集群访问授权
注意
集群 API Server 需要开启外网访问权限。
2. 创建 UFS 数据集 Dataset(COS 为例)
先创建 secret.yaml 用于加密, 模版如下:
apiVersion: v1
kind: Secret
metadata:
name: mysecret
stringData:
fs.cosn.userinfo.secretKey: xxx
fs.cosn.userinfo.secretId:xxx
创建secret:
[root@master01 ~]
secret/mysecret created
dataset.yaml 模版如下:
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
创建 dataset
[root@master01 run]
dataset.data.fluid.io/slice1 created
查询 Dataset 状态,处于 NotBond 状态:
[root@master01 run]
NAME UFS TOTAL SIZE CACHED CACHE CAPACITY CACHED PERCENTAGE PHASE AGE
slice1
NotBound 11s
3. 创建 runtime
runtime.yaml 模板如下:
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.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:
- "-Xmx16G"
- "-Xms16G"
- "-XX:+UseG1GC"
- "-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
创建 runtime:
[root@master01 run]
goosefsruntime.data.fluid.io/slice1 created
检查 goosefs 组件状态:
[root@master01 run]
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. 预热数据
dataload.yaml 预热组件如下:
apiVersion: data.fluid.io/v1alpha1
kind: DataLoad
metadata:
name: slice1-dataload
spec:
dataset:
name: slice1
namespace: default
此时 Dataset 处于 Bond 状态,Cached 比例是0%。
[root@master01 run]
NAME UFS TOTAL SIZE CACHED CACHE CAPACITY CACHED PERCENTAGE PHASE AGE
slice1 97.67MiB 0.00B 4.00GiB 0.0% Bound 31m
执行数据预热:
[root@master01 run]
dataload.data.fluid.io/slice1-dataload created
查看数据预热进度:
[root@master01 run]
NAME UFS TOTAL SIZE CACHED CACHE CAPACITY CACHED PERCENTAGE PHASE AGE
slice1 97.67MiB 52.86MiB 4.00GiB 54.1% Bound 39m
slice1 97.67MiB 53.36MiB 4.00GiB 54.6% Bound 39m
slice1 97.67MiB 53.36MiB 4.00GiB 54.6% Bound 39m
slice1 97.67MiB 53.87MiB 4.00GiB 55.2% Bound 39m
slice1 97.67MiB 53.87MiB 4.00GiB 55.2% Bound 39m
数据预热完成100%:
[root@master01 run]
NAME UFS TOTAL SIZE CACHED CACHE CAPACITY CACHED PERCENTAGE PHASE AGE
slice1 97.67MiB 97.67MiB 4.00GiB 100.0% Bound 44m
5. 检查数据
[root@master01 run]
NAME READY STATUS RESTARTS AGE
slice1-dataload-loader-job-km6mg 0/1 Completed 0 12m
slice1-fuse-xsvwj 1/1 Running 0 17m
slice1-master-0 2/2 Running 0 19m
slice1-worker-fzpdw 2/2 Running 0 17m
进入 goosefs master 容器:
[root@master01 run]
Defaulting container name to goosefs-master.
列出 goosefs 目录:
[root@VM-2-40-tlinux goosefs-1.0.0-SNAPSHOT-noUI-noHelm]
