標題[問題] 容器建置失敗並且無法移除
時間Mon Sep 5 21:13:28 2022
大家好，linux新手請教。
前陣子上課學到了singularity使用容器方法
在taiwania1上打算建置一個裝有化學模擬軟體的映像檔(無root權限)
但在安裝編譯器時似乎出了一點問題，重新登入之後打算直接使用 rm -rf 把整個資料夾
刪
但卻出現權限不足的問題，如同下面所示，想請問有沒有辦法能安全的將這錯誤的汙點給
移
因為怕會不會是因為掛載到一些資料夾導致不能刪除，怕亂刪容器會導致帳號下的其他重

1F：→ roccqqck: 用sudo09/05 23:47
2F：→ Harston: 找了好久在國外論壇上也有相同狀況 09/06 00:29
3F：→ Harston: 最後解法是用chmod -R +rw修改整個資料夾權限 09/06 00:30
4F：→ Harston: 就可以用rm -rf將容器刪除了 09/06 00:31
5F：→ Harston: 奇怪的是明明一開是我帳號創建的資料夾，為什麼卻沒權限09/06 00:32
7F：→ Harston: 給以後遇到類似問題的人參考 09/06 00:35
8F：→ roccqqck: 容器內部是root阿 這是正常現象 09/06 08:00
9F：→ Harston: 但用singularity進入容器好像id不會變 09/06 12:32
10F：→ roccqqck: 我不確定你這工具的原理是什麼 09/06 13:19
11F：→ roccqqck: 一般image裡面uid是寫死的 跟你使用的user uid無關 09/06 13:20
原來如此，下次注意看看
12F：→ lycantrope: 照singularity網站說明，用exec --writable 應該可以 09/06 15:10
13F：→ lycantrope: 修改內容，執行rm -rf應該通用? 09/06 15:11
了解，謝謝你的提供
