我正在嘗試使用 nginx 創建一個簡單的靜態 Web，并希望通過 Dockerfile 創建所有內容，問題是每當我嘗試創建 index.html 檔案時，它都會出現錯誤，我什至嘗試測驗它及其使用“index.htm”但不使用正確的格式。
FROM centos:7
#update and install nginx section
RUN yum update -y
RUN yum install -y epel-release
RUN yum install -y nginx
#create path and add index.html
WORKDIR /usr/share/nginx/html
#this one working with no issue
RUN touch index.htm
#this one will get failed
RUN touch index.html
EXPOSE 80/tcp
CMD ["nginx", "-g", "daemon off;"]
這是錯誤輸出：

該檔案已經存在并且歸 root 所有：
RUN ls -al index.html
---> Running in 27f9d0ae6240
lrwxrwxrwx 1 root root 25 Dec 23 12:08 index.html
-> ../../doc/HTML/index.html
洗掉它并重新創建它：
FROM centos:7
#update and install nginx section
RUN yum update -y
RUN yum install -y epel-release
RUN yum install -y nginx
RUN yum install -y vim
#create path and add index.html
WORKDIR /usr/share/nginx/html
RUN rm index.html
RUN touch index.html
EXPOSE 80/tcp
CMD ["nginx", "-g", "daemon off;"]
請注意，通常您應該將多個RUN命令組合在一起。
uj5u.com熱心網友回復：
您可以使用echo以下方法創建新檔案：
RUN echo " " > index.htm
uj5u.com熱心網友回復：
你應該創建一個檔案，你可以使用
復制 index.html index.html
命令到 Dockerfile 以在構建時將檔案復制到映像中
或使用
echo " " > index.html 命令創建檔案
uj5u.com熱心網友回復：
在您的 Dockerfile 中，您可以RUN {command}在命令列中使用like。
RUN mkdir -p /home/foo/
RUN echo "Hello World" > /home/foo/index.html
