 # MIGRATING TO THE CLOUD WITH CONTAINERIZATION

In this project,when i talk about containers, I imply docker. Although there are other containerization technology,docker is the standard tool for deploying application its dependencies and configuration in a sandbox also known as containers in an operating system.

For my previous projects, i have been using VMs to deploy web solution. For efficiency purpose, i will be using docker to deploy my application.Unlike a VM, Docker allocated not the whole guest OS for your application, but only isolated minimal part of it - this isolated container has all that your application needs and at the same time is lighter, faster, and can be shipped as a Docker image to multiple physical or virtual environments, as long as this environment can run Docker engine. This approach also solves the environment incompatibility issue. It is a well-known problem when a developer sends his application to you, you try to deploy it, deployment fails, and the developer replies, "- It works on my machine!". With Docker - if the application is shipped as a container, it has its own environment isolated from the rest of the world, and it will always work the same way on any server that has Docker engine.

 ## Installing docker engine

For the purpose of this project, i installed docker desktop that is conpartible with my local host.



## Deploying mySQL into a container in docker engine.

`docker run --name  -e MYSQL_ROOT_PASSWORD= -d mysql/mysql-server:latest`

I aaded the needed values into the command and the got the container up and running.



## Connecting to the MySQL Docker Container

I connected directly to the mySQL server as to creating another container to serve as mySQL client

`docker exec -it mubarokah mysql -uroot -p`



## Preparing database schema

- Cloning the following repository (git clone https://github.com/darey-devops/tooling.git)

- Exporting the location of the SQL file that contains data for setting up the MySQL database: `export tooling_db_schema=~/tooling_db_schema.sql`

- Using the SQL script to create the database and prepare the schema:  `docker exec -i mysql-server mysql -uroot -p$MYSQL_PW < $tooling_db_schema`

  

- I updated the db_conn.php with the connection details to the database.

    $servername = "mysqlserverhost";

    $username = "mubarokah";

    $password = "*****";

    $dbname = "toolingdb";

## Runing the Tooling Application

Containerizing the Tooling Appliaction

- I ran the following command in the directory that has dockerfile

  'docker build -t tooling:0.0.1'

  

  - Running the container

 

   'docker run --network tooling_app_network -p 8085:80 -it tooling:0.0.1'

  



## Migarating the php-Todo app into a containerized application

- Cloning this repsository 'https://github.com/Mubarokahh/php-todo.git'

- I created mysql container for the php-todo

  

  

- The dockerfile

  

- Creating a docker image with the build command

  

 `docker build -t php-todo:0.0.3 .`

  

- Running the container

- Running the artisan migrate command inside the php-todo container since it was ignored during the build process
