What steps to create a Docker image for Ubuntu 16:04, php 5.6 and apache (with Composer, xdebug, phpunit, npm and REDIS)?

I am a beginner in Docker and am trying to create an image with the following specifications:

The source OS has to be the original Ubuntu 16.04. I can not use images already available in the docker hub;

You must have installed apache - latest version;

You must have installed php and some libraries. It has to be php 5.5.38 (ideal) or 5.X last update or lastly 5.6.X latest update.

You must have REDIS installed.

REDIS, APACHE and php should be available as soon as the container is created, that is, initialized automatically.

The system root (/ var / www / html) should point to a / home / username / vhosts / mySite volume. The host is a MAC OS.

The system has to be accessed from the host browser through mysite-dev1 or mysite-dev2 or mysite-devN ...

The ultimate goal is to create an image that will be shared among all the company's developers.

This is the Dockerfile I'm using:

FROM ubuntu:16.04

#1
RUN apt-get update
#2
RUN apt-get install -y apache2
#3
RUN apt-get install -y php5
#4
RUN apt-get install -y redis-server
#5
RUN apt-get install -y php5-redis

COPY /home/username/vhosts/mySite /var/www/html

EXPOSE 80

Next I'm encountering some errors:

Operation # 3, php5 is not part of the ubuntu 16.04 package list. This post it turns out that it needs to be updated as follows:

#6
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install php5.6

Operation # 6, I get an error saying that sudo is not recognized as a command (even if I try to run in iterative mode on the -ti terminal). Doing a search I find that sudo is not enabled in the Ubuntu16.04 image.

If I try to run without sudo via terminal ( docker run -ti ... ), I get a message saying add-apt-repository not found .

Doinga another search for this error I find that add-apt-repository is also not available for Ubuntu images 14.04 in docker. And apparently tbm is not available for 16.04. The proposed solution is to run:

#7
apt-get install -y software-properties-common python-software-properties

Running this operation # 7 I get the following error: Doinganothersearch,Ifindthis post that suggests modifying apt.conf located in /etc/apt/apt.conf . And this is the contents of the apt directory from within the ubuntu 16.04 image .

Thatis,itdoesnothaveapt.conf.Doingasearchonsomeapt.conf posts needs to be created.

My conclusion is that I must be doing something very wrong because the goal is to just install php5.6 in Ubuntu16.04.

In conclusion, would anyone know how to say some tried-and-tested way to create an image with the features listed above without going through the previous steps?

UPDATE: It looks like other images have the same problem when they try to install version 5.6 of php .

Although Docker's ideology is to individualize processes by running each of them in different containers, I'll post my solution with REDIS here in a single container.

It is worth noting the comments of @Luiz Carlos. Using REDIS inside the same container running php, apache, etc. is not a good practice.

O Dockerfile : Prepared with php 5.6, Apache, PHPUnit, xdebug, REDIS, Composer, NPM.

# How could I ping my docker container from my host // https://stackoverflow.com/questions/39216830/how-could-i-ping-my-docker-container-from-my-host
# docker inspect 64ad351e115f give me "IPAddress": "172.17.0.2",
# How to get a Docker container's IP address from the host? docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 64ad351e115f 172.17.0.2

This is the entrypoint.sh that will inject the ip dynamically in php.ini by going to xdebug.remote_host:

#!/bin/bash
set -e

# Check if our environment variable has been passed.
if [ -z "${REMOTE_HOST}" ]
then
  echo "REMOTE_HOST has not been set."
  exit 1
else
  sed -i.bak "s/\$REMOTE_HOST/${REMOTE_HOST}/g" /usr/local/etc/php/php.ini
fi

exec "$@"
