Today we’re going to learn how to build and run a project with Apache web server in Docker. Let’s start:

You can take a look at basic docker commands.

Create a Project

First of all, let’s create a simple project. I’m going to make a simple project. The project will contain only the index.html file. Your project may contain more files.

My docker project’s structure:

So, the main project’s files will be stored in the app folder.

Create Dockerfile

Outside of the app folder, we need to create a file called Dockerfile. A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. To know more about Dockerfile, please Dockerfile reference.

We’re going to write all commands in Dockerfile to create a Docker image for our project.

# pull latest CentoOS
FROM centos:latest
# the maintainer name
MAINTAINER Obydul
# install apache
RUN dnf -y install httpd
# copy our app's files to apache's public dorectory
COPY ./app/ /var/www/html/
# keep apache server running
CMD ["/usr/sbin/httpd", "-D", "FOREGROUND"]
# listen the port 80 for apache on CentOS
EXPOSE 80

Build and Run as Container

We’ve created our project and wrote a Dockerfile to create an image. Let’s build the project:

docker build -t apacheserver ./

Here, ./ defines the Dockerfile’s location.

Now let’s run the container at our machine’s port 90:

docker run -p 90:80 apacheserver

Visit http://localhost:90 and see the output. If you are testing on live server, you need to replace localhost with the server IP or hostname.

The tutorial is over. Thank you.
