Task 1 - Ansible

STEPS TO DO THIS TASK :

?? Configure Docker

?? Start and enable Docker services

?? Pull the httpd server image from the Docker Hub

?? Run the httpd container and expose it to the public

?? Copy the html code in /var/www/html directory and start the webserver.

let's see how it works, for this we will need two nodes controller node and managed node, on the controller node we will run our ansible and on the managed node we will configure the docker by using ansible.

we cannot install Ansible using yum command to install ansible we need to use pip3 command and the command is pip3 install ansible and to check the ansible or the version of ansible we have a command ansible --version.

now we will tell our controller node about our managed node, for that we have to make an entry in the file /etc/myhosts.txt. in that file, we will give the IP, username, and password of our managed node. we can also add multiple IPs in the file if we have multiple managed nodes.

and to list all the managed nodes we have a command which will help our controller node to know how many managed nodes he has.

we have to do entry in the configuration file of ansible and tell the ansible about all our inventories . To run this playbook we need to give ssh permission. This can be done via host_key_checking=FASLE.

to check the connectivity between the controller node & managed node or to check whether they are pingable or not we have a ping command.

now we will create our playbook. Ansible supports YAML language to in playbook.

Now we will run our playbook

as you can see our playbook is successfully running, now we will go to our managed node and check whether the repository of docker has been created or not and we will also check the status of the docker.

now as our repo has been created and service is also active, we will further check whether our container has been launched or not.

As you can see that we have launched our container myos successfully. You can also check the ip of that container.

Now you can connect this IP and see the web page.

Thank You!
