背景介绍
离线开发环境需要连接阿里云 OSS 服务， 通过调研我们决定使用 oss-emulator 模拟 OSS 服务。
项目介绍
oss-emulator 是阿里开源的轻量级 OSS 服务模拟器，提供与 OSS 服务相同的 API 接口
但该项目仅提供基于 linux 部署方案，不支持容器化，无法满足容器化部署场景

因此，我将 oss-emulator 项目打包成镜像发布到 docker hub，并提供容器化部署方案，便于后续使用。
容器化过程及验证
需求依赖：docker hub 账号
- fork项目
fork.png
- 配置 docker hub 账号口令
用于后续 github action 自动构建使用

票据内容如下：
github-secret.png
- 登录 docker hub 创建 oss-emulator 仓库
create-repo.png
到此为止，我们准备工作已经完成，接下来就是将项目打包成镜像
- 项目根新增 Dockerfile ,内容如下
FROM ruby:alpine
MAINTAINER weiliang-ms@github
WORKDIR /work
ADD . .
RUN gem install thor builder webrick
CMD ["ruby","/work/bin/emulator", "-r", "store", "-p", "8080"]
- 项目根新增 github action 流水线配置
配置路径：.github/workflows/build.yml
配置内容如下：
name: ci
on:
push:
branches:
- 'master'
jobs:
docker:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
-
name: Set up QEMU
uses: docker/setup-qemu-action@v1
-
name: Set up Docker Buildx
uses: docker/setup-buildx-action@v1
-
name: Login to DockerHub
uses: docker/login-action@v1
with:
username: ${{ secrets.DOCKERHUB_USERNAME }}
password: ${{ secrets.DOCKERHUB_TOKEN }}
-
name: Build and push
uses: docker/build-push-action@v2
with:
context: ./
file: Dockerfile
push: true
tags: xzxwl/oss-emulator
提交变更后，github action 流水线基于配置进行镜像构建，最终将生成的 xzxwl/oss-emulator 镜像推送至 docker hub
- 启动 oss-emulator 容器
$ mkdir -p /work/oss-data
$ docker run -idt --name oss-emulator -p 8080:8080 -v /work/oss-data:/work/store xzxwl/oss-emulator
- 下载 ossutil 测试管理 oss-emulator
下载授权
$ wget https://gosspublic.alicdn.com/ossutil/1.7.14/ossutil64
$ chmod 755 ossutil64
- 测试 OSS 可用性
测试创建 bucket 功能
$ ./ossutil64 -e http://127.0.0.1:8080 -i AccessKeyId -k AccessKeySecret mb oss://bucket-test

测试查询 bucket
$ ./ossutil64 -e http://127.0.0.1:8080 -i AccessKeyId -k AccessKeySecret ls oss://bucket-test
Object Number is: 0

测试上传文件
$ touch test.file
$ ./ossutil64 -e http://127.0.0.1:8080 -i AccessKeyId -k AccessKeySecret cp test.file oss://bucket-test/
Succeed: Total num: 1, size: 0. OK num: 1(upload 1 files).

该项目并非完全兼容 OSS 接口，仅支持以下接口内容，使用时注意
接口兼容性
-
oss-emulator 支持
put, get, list, copy, delete, multipart等数据操作API接口，支持部分Bucket操作接口。
Bucket相关接口
- 支持
ListBuckets(GetService),PutBucket(CreateBucket),GetBucket,DeleteBucket,
GetBucketLocation,GetBucketInfo,PutBucketACL,GetBucketACL
- 不支持
PutBucketLogging,PutBucketWebsite,PutBucketReferer,PutBucketLifecycle,
GetBucketLogging,GetBucketWebsite,GetBucketReferer,GetBucketLifecycle,
DeleteBucketLogging,DeleteBucketWebsite,DeleteBucketLifecycle
Object相关接口
- 支持
PutObject,CopyObject,AppendObject,GetObject,DeleteObject,DeleteMultipleObjects,
HeadObject,GetObjectMeta,PutObjectACL,GetObjectACL
- 不支持
PostObject,Callback,PutSymlink,GetSymlink,RestoreObject
Multipart相关接口
- 支持
InitiateMultipartUpload,UploadPart,CompleteMultipartUpload
- 不支持
UploadPartCopy,AbortMultipartUpload,ListMultipartUpload,ListParts
容器化部署方式
docker
创建数据持久化目录
$ mkdir -p /oss-store
启动服务
$ docker run -idt --name oss-emulator -p 8080:8080 --restart=always -v /work/oss-data:/work/store xzxwl/oss-emulator
kubernetes
创建 pvc
$ cat <<EOF | kubectl apply -f -
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: oss-emulator-volume
namespace: test
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 50Gi
EOF
创建 deployment
$ cat <<EOF | kubectl apply -f -
kind: Deployment
apiVersion: apps/v1
metadata:
name: oss-emulator
namespace: test
labels:
app: oss-emulator
spec:
replicas: 1
selector:
matchLabels:
app: oss-emulator
template:
metadata:
labels:
app: oss-emulator
spec:
volumes:
- name: host-time
hostPath:
path: /etc/localtime
type: ''
- name: volume-b5cw22
persistentVolumeClaim:
claimName: oss-emulator-volume
containers:
- name: container-14y7vu
image: xzxwl/oss-emulator
ports:
- name: http-8080
containerPort: 8080
protocol: TCP
resources:
limits:
cpu: 200m
memory: 400Mi
volumeMounts:
- name: host-time
readOnly: true
mountPath: /etc/localtime
- name: volume-b5cw22
mountPath: /work/store
imagePullPolicy: IfNotPresent
restartPolicy: Always
terminationGracePeriodSeconds: 30
dnsPolicy: ClusterFirst
serviceAccountName: default
serviceAccount: default
securityContext: {}
schedulerName: default-scheduler
EOF
创建 service
$ cat <<EOF | kubectl apply -f -
kind: Service
apiVersion: v1
metadata:
name: oss-emulator-svc
namespace: test
labels:
app: oss-emulator-svc
spec:
ports:
- name: http-8080
protocol: TCP
port: 80
targetPort: 8080
selector:
app: oss-emulator
EOF
此时即可在 kubernetes 内部通过以下地址使用 oss 服务
oss-emulator-svc.test:80
AK, SK 可以配置如下
AK: AccessKeyId
SK: AccessKeySecret
对于 xzxwl/oss-emulator 这个镜像，离线环境下可以上传至私有镜像库（例如harbor）进行管理使用
