docker容器配置的端口對應(yīng)關(guān)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(yīng)該是沒關(guān)系的，docker的關(guān)系映射相當(dāng)于是再virtual box里面配了一個端口匹配規(guī)則，不會占用這個端口的，相當(dāng)于外部端口轉(zhuǎn)發(fā)到內(nèi)部容器端口里。所以你這個錯誤應(yīng)該是docker內(nèi)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(jìn)程已經(jīng)啟動了, 這時你當(dāng)然不能再在80上啟動另一個

題主可以進(jìn)入nginx的docker container實(shí)例，查看一下nginx是否已經(jīng)啟動：

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

如果已經(jīng)啟動，則不需要在重復(fù)啟動了

你這已經(jīng)是在容器中了吧，你的nginx容器啟動后，80端口就已經(jīng)起來了，你在運(yùn)行nginx，肯定顯示被占用了。
