In this post I choose to work with GKE For change,
The Idea with this project which is Simple WordPress application connected to external database (MYSQL) you can change the database IP from the main.tf file.

Inspect Docker layer
In this post , I will share one of the ways showing how to know what is the size of the image plus the layer of the image
To do that follow the steps
- Create Linux variable one for the layer the other one for the size with the following
export showLayers='{{ range .RootFS.Layers }}{{ println . }}{{end}}'
export showSize='{{ .Size }}'
- Check The size like the below
docker inspect -f "$showSize" <Container-name:tag>
- Check the Layer like the below
docker inspect -f "$showLayers" <Container-name>Regards

Storing container data in AWS s3
In this Post I will discuss how to Use S3 Bucket in Docker containers, Let’s Start
Configuration and Installation
- Install the awscli, while checking if there are any versions currently installed, and not stopping any user processes
pip install --upgrade --user awscli- Configure the CLI:
aws configure- Enter the following:
- AWS Access Key ID: <ACCESS_KEY_ID>
- AWS Secret Access Key: <SECRET_ACCESS_KEY>
- Default region name: <Region>
- Default output format: json
- Copy the CLI configuration to the root user
sudo cp -r ~/.aws /root- Install the s3fs package
sudo yum install s3fs-fuse -yConfigure Bucket
- Create a mount point for the s3 bucket
sudo mkdir /mnt/application-website- Export the bucket name
export BUCKET=<S3_BUCKET_NAME>- Mount the S3 bucket
sudo s3fs $BUCKET /mnt/application-website -o allow_other -o default_acl=public-read -o use_cache=/tmp/s3fs- Verify that the bucket was mounted successfully
ll /mnt/application-website- Copy the website files to the s3 bucket
cp -r ~/application-website/web/* /mnt/application-website- Verify the files are in the folder
ll /mnt/application-website- Verify the files are in the s3 bucket
aws s3 ls s3://$BUCKETRun container using volume s3
- Run an httpd container using the S3 bucket
docker run -d --name web1 -p 80:80 --mount type=bind,source=/mnt/application-app,target=/usr/local/apache2/htdocs,readonly httpd:2.4- In a web browser, verify connectivity to the container
You can check the application <Server-Public-IP:80>

Docker – Saving and Loading Image
Quick post to show you how to save and load image using save/load command
Docker image save <IMAGE> > <FILE>.tar
Docker image save <IMAGE> -o <FILE>.tar
Docker image save <IMAGE> -output <FILE>.tarto Load these Image again
Docker image load < <FILE>.tar
Docker image load -I <FILE>.tar
Docker image load –input <FILE>.tarEnjoy Automation

AWS ECS Project
This is another DevOps Project, the idea of this project like the following:-
sample django web application on with the following specs:–
- app should be production ready taking into consideration things such as scalability, availability & security.
- The infrastructure to run this application is up to you but it should be automated via terraform or cloud formation. Infrastructure well architected framework will be used to evaluate the infrastructure as a whole.
- CI/CD Pipeline
- harden the application for a production ready environment.
The complete Project uploaded to my GitHub HERE.
Thank you
Enjoy the automation

Case study for software architect
Problem Description
We have two separate applications that we would like to integrate together. One is a WYSIWYG application for generating static websites. The other is an admin application for managing an online shopping site. We would like to be able to use the features of the Website Builder to design pages in the Webshop. In addition, we would also like to be able to manage product details (name, price, images, etc.) while updating Webshop pages in the Website Builder.
Website Builder Details
The Website Builder is a single page app written in React. It is mostly served by a monolithic backend with a few services for select features. The app follows a component-driven architecture using Redux for application state management. Each static page in a user’s website is composed of components. Each component is responsible for rendering the view within its container and for supplying the callbacks for displaying its settings panel. The settings panel is unique per component but may share various individual controls for certain
settings (eg: background color, fonts).
When the user is ready to publish their site, the publication service will generate static assets for each page. The Webshop is one component in the Website Builder. When a Webshop is included on a page, a JavaScript snippet is included in the generated HTML.
Webshop Details
The Webshop has 2 parts: the admin portion is a single page app written in KnockoutJS. It is in the process of being rewritten in React. The second portion is the public-facing shop front, also a Knockout application written in KnockoutJS. The admin application lists products, orders, and other management details. The Webshop backend is quite similar to the Website Builder – monolithic aside from a few minor services for certain features.

DevOps Project – Complete auto deployment and IAAC
The following project having these requriment:-
- I want to have a CI/CD pipeline for my application the pipeline must build and test the application code base.
- The pipeline must build and push a Docker container ready to use.
- The pipeline must deploy the application across different environments on the target infrastructure.
- Separate the backend and the frontend in different pipelines and containers.
Another Things to add to this project which is the follwong :-
- the infrastructure must be created on the cloud, for the purpose of the assignment any public cloud can be used.
- The deployment pipeline must use infrastructure as code using Terraform
- The delivered infrastructure must be monitored and audited.
- The delivered infrastructure must allow multiple personal accounts.
- The delivered infrastructure must be able to scale automatically.
- Modify the application to make use of real database running on the cloud, instead of the in-memory database.

ansible provisioning for instance (Cloud Version) Using Pipelines
Imagine you are having multiple instances and you want to change something, if you will do this manually it will take time from you why not to automte the process ?
I upladed one of the projects to automate the process, this will allow to automate the simplest things for example new employee joined and you need to add his SSH key to your instances (You can even choose which VM you want to him/her to acces) , just add the key in the roles and configure the pipeline on your rep and the code will run Automtically.
I uploaded the project on my github HERE.
