In this blog i will show how to Create an Ansible Playbook that will retrieve the IP of newly launched Docker Container and update it in the Inventory file and also launch a Webserver on top of it using Ansible Playbook.
For this I have created my own customized centos image for enabling ssh inside a docker container and uploaded in docker hub click here to check it.
I have created the image using Docker file
create a file named [Dockerfile] and enter the code below .
🔶 Step 1: Create a key pair
🔶 Step 2: Create a security group
🔶 Step 3: Launch an instance using the above created key pair and security group.
🔶 Step 4: Create an EBS volume of 3Gib.
🔶 Step 5: The final step is to attach the above created EBS volume to the instance you created in the previous steps.
So lets start
Firstly lets create a IAM user on AWS so that we can login through our local system Command prompt
Static Partition saves your time in loading data compared to dynamic partition. You “statically” add a partition in the table and move the file into the partition of the table. We can alter the partition in the static partition.

OpenShift is a family of containerization software products developed by Red Hat. Its flagship product is the OpenShift Container Platform — an on-premises platform as a service built around Docker containers orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux
Jenkins is a self-contained, open-source automation server which can be used to automate all sorts of tasks related to building, testing, and delivering or deploying software.
Continuous integration pipeline is a set of sequential or parallel jobs, these jobs are designed to perform a set of tasks which are configured using the GUI interface.
The core technology driving that initiative was Jenkins, an open source tool to build continuous integration and continuous delivery (CI/CD) pipelines. … And the open source version of Jenkins was the obvious choice due to its flexibility, openness, powerful plugin-capabilities, and ease of use.
Kubernetes is an open-source container-orchestration system for automating computer application deployment, scaling, and management. It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation.
