1. 借鑒
2. 開始
在docker中因為配置錯誤呢燥，導(dǎo)致容器一直無法啟動，使用docker logs -f containerId發(fā)現(xiàn)報錯但是只能隔岸觀火噶咋整诈茧。
【緣起】
nginx因為配置問題導(dǎo)致無法啟動，docker ps查看不到進程號
我們使用docker logs查看一下日志
docker logs -f nginx01

由此我們可以看到是因為/etc/nginx/nginx.conf這個文件的11行有問題導(dǎo)致的。
【解決】
- 如果配置了路徑映射，直接修改對應(yīng)的文件乘客，重啟即可。
- 如果沒有設(shè)置路徑映射淀歇，將容器中的文件復(fù)制到主機易核，修復(fù)之后覆蓋回去即可。
我的這個問題是屬于第二類浪默，所以依次執(zhí)行以下步驟:
① 將/etc/nginx/nginx.conf配置文件cp到主機
docker cp nginx01:/etc/nginx/nginx.conf /Users/xxx/Desktop/
② 修改配置文件
③ 將配置文件寫回容器
docker cp /Users/xxx/Desktop/nginx.conf nginx01:/etc/nginx/nginx.conf
④ 啟動容器
docker start nginx01
⑤ 查看進程號
