Ansible playbook that will retrieve new Container IP and dynamically update the inventory and Configure web-server inside that Docker Container

ARTH — Task 14 

Task Description??

14.2 Further in ARTH — Task 10 have to create an Ansible playbook that will retrieve new Container IP and update the inventory. So that further Configuration of Webserver could be done inside that Container.

Lets Start

In this task I have used my own pre-created docker image which is enabled with ssh. So that Ansible can use ssh protocol to login to new docker container and configure webserver inside it.

Code of Dockerfile

In my case I am having Controller Node having IP on which the ansible is installed

Lets check the ansible version installed on my controller node:

ansible --version

Initially inventory file is empty

cat /root/ip.txt

Configure ansible.cfg

vim /etc/ansible/ansible.cfg

Ansible Playbook :

vim docker.yml

vim docker-web.yml

dockerip.j2 file

Task14.html file

Now let’s run the Playbook

ansible-playbook docker.yml

Container is successfully launched with name Webos.

Inventory file dynamically updated

Check Docker Service started and enabled:

Now we can run our docker-web.yml playbook to configure webserver inside container:

Done! 

Now checking webos container:

Now the webserver has been deployed on the docker container.

So Let’s check our webpage from the browser:
