docker容器配置的端口對應關系: 22/tcp, 0.0.0.0:80->80/tcp

問題解答

不是很確定，但是和docker的端口映射應該是沒關系的，docker的關系映射相當于是再virtual box里面配了一個端口匹配規則，不會占用這個端口的，相當于外部端口轉發到內部容器端口里。所以你這個錯誤應該是docker內部端口被占了。試一下lsof -i :80看看

用的什么鏡像? 如果官方的nginx的話, nginx進程已經啟動了, 這時你當然不能再在80上啟動另一個

題主可以進入nginx的docker container實例，查看一下nginx是否已經啟動：

ps -ef | grep nginx# ornetstat -ntpl | grep 80

如果已經啟動，則不需要在重復啟動了

你這已經是在容器中了吧，你的nginx容器啟動后，80端口就已經起來了，你在運行nginx，肯定顯示被占用了。
