What is Apache HTTP Server ?

What is Docker ?
Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.
Let’s get Started
To check weather the target node is ping able or not.
command :- ansible all -m ping
- Configure Docker
First we need to get the software / package of docker then install the docker
2. Starting and Enabling the Services of Docker
3. Downloading Apache HTTP Image from Docker Hub
4. Creating directory for storage as it’s clearly mention the by default location is /usr/local/apache2/htdocs/ as in my case its not there.
If u run webserver with this location u’ll get output something like this “ IT WORKS”
5. Now to run Docker Container using Ansible we need install library as its mention in the ansible documentation.
package name -: docker-py ( ansible ansible is built over python so it supports python libraries)
6. Now Launch the container and expose it’s port (8080)
NOW LET’S RUN PLAYBOOK
Now Let see the Output
