# Apache Docker Setup
###### tags: `web develope`

## Before Works
Make sure there is 3 directory:

* **www**: store code of html, javascript and css
* **logs**: store apache logs files
* **conf**: store apache conf files

Plus **httpd-foreground** and **Dockerfile**

FROM debian:jessie

ENV HTTPD_PREFIX /usr/local/apache2
ENV PATH $PATH:$HTTPD_PREFIX/bin
RUN mkdir -p "$HTTPD_PREFIX" \
    && chown www-data:www-data "$HTTPD_PREFIX"
WORKDIR $HTTPD_PREFIX

# install httpd runtime dependencies
# https://httpd.apache.org/docs/2.4/install.html#requirements
RUN apt-get update \
    && apt-get install -y --no-install-recommends \
    
--------<snip>--------

COPY httpd-foreground /usr/local/bin/

EXPOSE 80
CMD ["httpd-foreground"]

the shell script **httpd-foreground** is used for start/exec httpd sevice.

#!/bin/bash
set -e

# Apache gets grumpy about PID files pre-existing
rm -f /usr/local/apache2/logs/httpd.pid

exec httpd -DFOREGROUND

Make sure you have privilege to execute httpd-foreground

~/apache$ chmod +x httpd-foreground
