背景介紹
離線開發(fā)環(huán)境需要連接阿里云 OSS 服務(wù)司致， 通過調(diào)研我們決定使用 oss-emulator 模擬 OSS 服務(wù)械媒。
項(xiàng)目介紹
oss-emulator 是阿里開源的輕量級 OSS 服務(wù)模擬器仁连，提供與 OSS 服務(wù)相同的 API 接口
但該項(xiàng)目僅提供基于 linux 部署方案，不支持容器化达舒，無法滿足容器化部署場景

因此灿渴，我將 oss-emulator 項(xiàng)目打包成鏡像發(fā)布到 docker hub，并提供容器化部署方案艺沼，便于后續(xù)使用册舞。
容器化過程及驗(yàn)證
需求依賴：docker hub 賬號
- fork項(xiàng)目

- 配置 docker hub 賬號口令
用于后續(xù) github action 自動(dòng)構(gòu)建使用

票據(jù)內(nèi)容如下：
github-secret.png
- 登錄 docker hub 創(chuàng)建 oss-emulator 倉庫
create-repo.png
到此為止，我們準(zhǔn)備工作已經(jīng)完成障般，接下來就是將項(xiàng)目打包成鏡像
- 項(xiàng)目根新增 Dockerfile ,內(nèi)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"]
- 項(xiàng)目根新增 github action 流水線配置
配置路徑：.github/workflows/build.yml
配置內(nèi)容如下：
name: ci
on:
push:
branches:
- 'master'
jobs:
docker:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
-
name: Set up QEMU

-
name: Build and push
uses: docker/build-push-action@v2
with:
context: ./
file: Dockerfile
push: true
tags: xzxwl/oss-emulator
提交變更后调鲸，github action 流水線基于配置進(jìn)行鏡像構(gòu)建，最終將生成的 xzxwl/oss-emulator 鏡像推送至 docker hub
- 啟動(dòng) 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
- 下載 ossutil 測試管理 oss-emulator
下載授權(quán)
$ wget https://gosspublic.alicdn.com/ossutil/1.7.14/ossutil64
$ chmod 755 ossutil64
- 測試 OSS 可用性
測試創(chuàng)建 bucket 功能
$ ./ossutil64 -e http://127.0.0.1:8080 -i AccessKeyId -k AccessKeySecret mb oss://bucket-test
0.005875(s) elapsed
測試查詢 bucket
$ ./ossutil64 -e http://127.0.0.1:8080 -i AccessKeyId -k AccessKeySecret ls oss://bucket-test
Object Number is: 0
0.006463(s) elapsed
測試上傳文件
$ 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).

該項(xiàng)目并非完全兼容 OSS 接口挽荡，僅支持以下接口內(nèi)容藐石，使用時(shí)注意
接口兼容性
-
oss-emulator 支持
put, get, list, copy, delete, multipart等數(shù)據(jù)操作API接口，支持部分Bucket操作接口定拟。
Bucket相關(guān)接口
- 支持
ListBuckets(GetService),PutBucket(CreateBucket),GetBucket,DeleteBucket,
GetBucketLocation,GetBucketInfo,PutBucketACL,GetBucketACL
- 不支持
PutBucketLogging,PutBucketWebsite,PutBucketReferer,PutBucketLifecycle,

容器化部署方式
docker
創(chuàng)建數(shù)據(jù)持久化目錄
$ mkdir -p /oss-store
啟動(dòng)服務(wù)
$ docker run -idt --name oss-emulator -p 8080:8080 --restart=always -v /work/oss-data:/work/store xzxwl/oss-emulator
kubernetes
創(chuàng)建 pvc
$ cat <<EOF | kubectl apply -f -
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: oss-emulator-volume
namespace: test
spec:
accessModes:

創(chuàng)建 deployment
$ cat <<EOF | kubectl apply -f -

此時(shí)即可在 kubernetes 內(nèi)部通過以下地址使用 oss 服務(wù)
oss-emulator-svc.test:80
AK, SK 可以配置如下
AK: AccessKeyId
SK: AccessKeySecret
對于 xzxwl/oss-emulator 這個(gè)鏡像于微，離線環(huán)境下可以上傳至私有鏡像庫（例如harbor）進(jìn)行管理使用
