In this tuto, I'll show you how to create Docker Images with a Dockerfile. Dockerfile allow you to quickly configure and create an image.

Before you create a dockerfile, you should become familiar with the dockerfile command. There are some dockerfile commands you must know:

FROM: allows you to define from which base your image has been created.
MAINTAINER: Optional, it contains the name of the maintainer of the image.
RUN: allows you to execute a command during the build process of the docker image.
ADD: allows you to copy a file from the host machine to the new docker image.
EXPOSE: allows to expose a container port to the outside.
CMD: determines the command that will be executed when the container starts.
ENTRYPOINT: Define the default command that will be executed when the container is running.
WORKDIR: allows you to define the working folder for all other commands (for example RUN, CMD, ENTRYPOINT and ADD)
ENV: allows you to define environment variables which can then be modified using the command parameter run --env <key>=<value>.
VOLUME: Enable access/linked directory between the container and the host machine.

Example:

Create Dockerfile file like this:

FROM debian:buster-slim

# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added
#RUN groupadd -r www-data && useradd -r --create-home -g www-data www-data

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

# install httpd runtime dependencies

CMD ["httpd-foreground"]

Build New Docker Image and Create New Container Based on it:

use this command line to build new docker image: 

docker build -t codimth_apache .

Now run the new container with the command below:

docker run -d -p 80:80 codimth_apache

For testing open the web browser and type the host machine IP address like this:

http://127.0.0.1:80
