Configuring HTTPD Server on Docker Container

STEP I : Install the docker software

Use this command :

yum install docker-ce --nobest

STEP II : Start the docker service

systemctl start docker

And now check the status of docker whether it is active or not by commnd

systemctl status docker

STEP III : Download centos image

Use this command to list the installed docker images

docker images 

In my case , I have only ubuntu image. So I can download the centos image by using the command

docker pull centos

[Note : Docker hub does not have Redhat image. So we can use the centos which is similar to the Redhat]

If we didn’t mention the version while downloading the image, then by default the latest version of os will get downloaded

After downloading, check with docker images command

STEP IV : Launch one container of Centos

docker run -it --name <container_name> <image_name:version>

STEP V : Install ifconfig command

Docker container do not have ifconfig command by default. We have to install it.

Use this command to install :

yum install whatprovides ifconfig

For ifconfig command we need to install net-tools software and we can install it by using yum or dnf. Command is -

yum install net-tools

Now use ifconfig command

Here my main network card is eth0 . So my ip of centos container is 172.17.0.2

STEP VI : Install httpd

For installing Apache webserver , use command :-

yum install httpd

After installation check by the rpm command whether it is installed or not

rpm -q httpd

STEP VII : Write html page

Write html pages inside /var/www/html directory

cd /var/www/html

Use vi command to write a html file

vi page.html

After writing the page , then go to the browser and write <ip>/<file_name.html>

eg. 172.17.0.2/page.html
