#first dockerfile FROM nginx:latest # RUN apt-get update # RUN apt-get install -y vim # RUN apt-get install -y nginx # 以上执行会创建 3 层镜像。可简化为以下格式: #RUN apt-get update && apt-get install -y vim && apt-get install -y nginx # 如上,以 && 符号连接命令,这样执行后,只会创建 1 层镜像。 #指定运行该镜像的容器使用的端口为 80 # docker run的时候 一定要加上 -P EXPOSE 8080 RUN useradd -m -u 1000 user # Switch to the "user" user USER user # Set home to the user's home directory ENV HOME=/home/user \ PATH=/home/user/.local/bin:$PATH # Set the working directory to the user's home directory WORKDIR $HOME #RUN mkdir /usr/share/nginx/html/app #RUN chown user /usr/share/nginx/html/app COPY --chown=user . /usr/share/nginx/html/ CMD ["nginx","-g","daemon off;"]
