bash：行：docker：找不到命令

Question

我在 docker 容器中使用 jenkins 並且想啟動另一個實例，每當我嘗試使用 docker 命令時

docker run -t -i ap/dashboard /bin/bash 

我收到此錯誤：

bash: line 61: docker: command not found

如何導航到另一個容器或解決此錯誤？

通過閱讀/root/.ash_history ，我可以清楚地看到虛擬機創建者能夠使用 docker 命令

以下是有關該系統的一些詳細信息：

我毫無希望地嘗試了許多 docker 命令

是因為我已經在容器里了嗎？？

嘗試使用docker run -t -i ap/dashboard /bin/ash 。

也許你的容器不使用bash所以你應該嘗試使用/bin/sh這是默認安裝的 shell 處理器的符號鏈接。
