如何在单个容器中运行两个 Docker 图像？

Question

我想用 PHP Image & Apache Image 创建一个单一的 Docker 容器，这里是我的 docker 文件。

Docker 文件名：单-container.dockerfile

# PHP image from docker hub
FROM php:7.2-cli


# Apache image from docker hub
FROM httpd:2.4

# public-html is path for my local codebase
COPY ./public-html/ /usr/local/apache2/htdocs/

在 docker CLI 中，当我运行这个命令时：docker build -f single-container.dockerfile . -t mysinglecontainer:latest

I'm getting below error.

请指教，有哪些改动需要修改？

Answer 1

把.移到最后

docker build -f httpd.Dockerfile -t mysinglecontainer:latest .

请务必在您的命令中使用正确的 Dockerfile 名称，名称是 single-container.dockerfile

所以命令是：

docker build -f single-container.dockerfile -t mysinglecontainer:latest .

CMD ["/bin/sh", "-c", "rm -f /usr/local/apache2/logs/httpd.pid && httpd -DBACKGROUND && php-fpm"]

will install PHP Alpine image

(1) FROM php:7.2-fpm-alpine

Configuration for Apache

(2) apk add --no-cache libzip mysql libxml2 libpng zlib freetype jpeg icu gmp git subversion libxslt openldap \

            terminus-font ghostscript-fonts

Last：在 Docker CLI 中，我运行命令 docker-compose up 现在在我的单一容器中，两者都 PHP & Apache 运行ning 成功。
