How can I run TWO Docker images in a SINGLE Container? - docker

Question

I want to create a Single Docker Container with PHP Image & Apache Image, here is my dockerfile.
Docker File Name: single-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/
In docker CLI when I run this command: docker build -f single-container.dockerfile . -t mysinglecontainer:latest
I'm getting below error.
Please advice, what are the changes needs to modify?

Answer 1

move the . to the end
docker build -f httpd.Dockerfile -t mysinglecontainer:latest .
be sure to use the correct Dockerfile name also in your command the name is single-container.dockerfile
so the command is:
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 \
apache2 apache2-ldap apache2-proxy libreoffice openjdk11-jre ghostscript msttcorefonts-installer \
terminus-font ghostscript-fonts
Last: In Docker CLI, I run the command docker-compose up and now in my Single Container, both PHP & Apache is running successfully.
