What is Docker?

  1. Docker Web Server Image
  2. Apache Web Server Flask Docker

In practice, MPMs extend the modular functionality of Apache by allowing you to decide how to configure the web server to bind to network ports on the machine, accept requests from clients, and use children processes (and threads, alternatively) to handle such requests.

  • In our example, we are going to use the Apache Web Server on Ubuntu to build our image. Let’s follow the steps given below, to build our web server Docker file. Step 1 − The first step is to build our Docker File. Let’s use vim and create a Docker File with the following information.
  • Apache web server is popular open source http web server tool which is widely used for deployment of webpages. It can be installed in any operating system. Advantage of using Docker 11) Application.
  • Tutorial Apache - Testing the Docker installation Open your browser and enter the IP address of your web server. In our example, the following URL was entered in the Browser.
How to Run a Web Server from a Docker Container? Yes, I Know IT ! Ep 16

Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.

What is a container?

A container is a runnable instance of an image. You can create, start, stop, move, or delete a container using the Docker API or CLI. You can connect a container to one or more networks, attach storage to it, or even create a new image based on its current state.
By default, a container is relatively well isolated from other containers and its host machine. You can control how isolated a container’s network, storage, or other underlying subsystems are from other containers or from the host machine.

Apace Webserver:- Apache HTTP Server is a free and open-source web server that delivers web content through the internet. It is commonly referred to as Apache and after development, it quickly became the most popular HTTP client on the web.

LET’S GET STARTED…………………………….

There are many ways to create a webserver in Docker but we follow then a simple one.

STEP 1:- CREATE A DIRECTORY WEBSERVER

STEP 2:- CREATE AN INDEX.HTML IN WEBSERVER DIRECTORY.

Paste the below code in index.html

STEP 3:- CREATE A FILE NAME DOCKERFILE IN WEBSERVER DIRECTORY WITH BELOW INSTRUCTIONS (THE NAME DOCKERFILE IS HARDCODED DON’T CHANGE IT)

Dockerfile Commands

  • Maintainer:- This command is used to give information about the author or manager who is managing this image MAINTAINER Bangmetric pvt. ltd.
  • From:- FROM instruction initializes a new build stage and sets the Base Image for subsequent instructions. As such, a valid Dockerfile must start with FROM instruction. The image can be any valid image – it is especially easy to start by pulling an image from the Public Repositories.
  • Run:- Before building an image if want some configuration that needs to be present in the image. Inside the image we need to install Apache web server image the command to install that image is “”RUN yum -y install httpd“.
  • Copy:- This command is used to copy a file from host os to docker container
    “”COPY index.html /var/www/html“.
  • EXPOSE:– This command is used to specify the port number in which the container is running its process. Anybody can come from outside and connect to this port. Apache webserver is launched at port 80 by default that is why we need to expose container at port 80. “EXPOSE 80
  • CMD:- To run a command as soon as container is launched. CMD command is different from RUN because RUN is used at the time of building an image and CMD used to run command when container is started.
  • /usr/sbin/httpd:- This command is used to start the web server
  • -D FOREGROUND:- This is not a docker command this is http server argument which is used to run webserver in background. If we do not use this argument the server will start and then it will stop.
  • CMD [“/usr/sbin/httpd”,” -D”,” FOREGROUND”]

STEP 4:- BUILD THE DOCKER IMAGE WITH DOCKER BUILD

Note:- -t option is to tag or name the image and . is used because you are in a directory where Dockerfile is present

STEP 5:- NOW CHECK THE IMAGE WITH DOCKER IMAGES

Docker Apache Web Server

STEP 6:- NOW RUN THE DOCKER IMAGE

-dit means run container in background -p define the port

STEP 7:- CHECK THE RESULT ON WEBBROWSER <IP:PORT>
