測試drone部署鏡像又遇到N個坑。第一個就是拉取鏡像被墻归敬。好吧，這個可以通過國內(nèi)鏡像解決。另一個就是一直在報的錯誤
Failed to create btrfs snapshot: inappropriate ioctl for device
硬件設(shè)置還是synology 716 + II

群暉docker信息
從信息中可以看到 Storage Driver為btrfs
在Use the BTRFS storage driver文中有這樣的提示：
Note: The btrfs storage driver is only supported on Docker CE on Ubuntu or Debian, and Docker EE / CS Engine on SLES.
折騰了一天多的時間和橙，看到這里郁悶了，好吧暫時放棄在群暉下測試drone造垛，換服務(wù)器測試.....
==,先梳理下思路魔招，看看還有什么沒測試到的地方
- docker運行在btrfs存儲上
- docker啟動drone的server和agent容器
- drone根據(jù)配置文件啟動一個測試容器（與drone是同一層級的容器）
- 測試容器內(nèi)啟動一個docker并根據(jù)dockerfile生成鏡像文件（Docker in Docker）
逐步測試：
- 在最外層測試創(chuàng)建鏡像 (測試通過）

- 測試是否與群暉登錄權(quán)限有關(guān) （無效）
手動測試全部正常，考慮是否是與權(quán)限有關(guān)。因不知道drone是否在啟動docker in docker是追加了權(quán)限乡翅，所以嘗試啟動群暉的root權(quán)限運行drone并設(shè)置docker的--privileged參數(shù) 鳞疲。參考：群暉root密碼設(shè)置
4.想到一個問題，在手動測試docker in docker時的info信息如下：
admin@sunsl-dev:~$ sudo docker run -it --rm --link some-docker:docker docker info
……
Server Version: 17.07.0-ce-rc2 #版本號
Storage Driver: vfs #這里才是重點
……
Kernel Version: 3.10.102
Operating System: Alpine Linux v3.6 (containerized)
OSType: linux
Architecture: x86_64
CPUs: 4
Total Memory: 7.719GiB
……
詳細測試記錄：docker run docker 手動測試記錄
看到區(qū)別了嗎蠕蚜？群暉存存格式是btrfs,而docker內(nèi)用的是vfs格式Ｉ星ⅰ！靶累！跪了Ｏ俸痢！挣柬！
然后....TMD繼續(xù)找資料潮酒，如何設(shè)置配置文件啊。
storage_driver
supports aufs, overlay or vfs drivers
.drone.yml
……省略其它pipeline部分
publish:
image: plugins/docker
registry: 192.168.123.202:55000

tags : latest
debug: true
insecure: true #私有倉庫未設(shè)置HTTPS需要啟用這個選項
storage_driver: vfs #出錯原因就是它
