Week-6

Hello, I want to write this blog after finishing my exam like an hour ago; I am looking over some class activities and see any questions to review, but something that sometimes confused me. I read the word “docker-compose” in some class-work exercises; I got interested and looked it up again. I found two links that helped me understand what Docker Compose does and how you use Docker Compose?.

Docker Compose: Run multiple containers as a single service or extend many different Docker containers midway. Even an essential tool for any application that needs various micro-services, as it allows each service to be in a separately managed container easily.

What Does Docker Compose Do?

Docker containers are running applications in an isolated environment. Its application deployments are arranged in Docker for the benefit. However, it’s often complex as running a single container. Usually, Many containers come together to act as one service made up of many changing parts.

Running all deployment time is disordered, so Docker provides Docker Compose; it runs multiple containers to clean it up. It helps all arrangements in one YAML file and starts all the containers with one 

command.

Rather than having all services in one big container, Docker Compose allows to split them up into individually manageable containers. This is better for building and deployment, and it can manage all of them in separate codebases and doesn’t need to start each container manually.

Using Docker Compose is a three-step process:

  • Build the part images using their Dockerfiles, or pull them from a registry.
  • Set all of the component services in a docker-compose.yml file.
  • Run all of them together using the docker-compose CLI.

Docker Compose still builds and publishes Docker containers using a Dockerfile. But, instead of running them directly, it can use Docker Compose to manage the configuration of a multi-container deployment.

How Do You Use Docker Compose?

The form for a docker-compose file is done in docker-compose.yml. It doesn’t need to place this at the root of a project like a Dockerfile. It can go anywhere as it doesn’t depend on any other code. However, it builds the images locally and will need to go into a project folder with the produced code.

A Compose configuration file that runs a WordPress instance using the WordPress container off the Docker Hub. However, this depends on a MySQL database, which Composes also creates.

  • First, a version number since the arrangement can change depending on which version.
  • Next, A list of Services. 
  • Lastly, the volumes are stored.

UML CLASS DIAGRAM

The UML Class Diagram is a graphical notation used to construct and visualize object-oriented systems. The UML (Unified Modeling Language) can help model systems in various ways. One of the more popular types in UML is the class diagram, which is popular among software engineers to document software architecture, class diagrams are a type of structure diagram because they describe what must be present in the system being modeled. The most positive point about UML or class diagrams, it is that it has been designed to be simple and easy to use.

When using the UML, the class shape itself while writing the code and it consists of a rectangle with three rows. The top is for the name of the class, the middle row contains the attributes of the class, and the bottom one expresses the methods or operations that the class may use. Classes and subclasses are grouped together to show the static relationship between each object.

Perspectives of Class Diagram

The choice of perspective depends on how far along you are in the development process. A diagram can be interpreted from various perspectives:

  1. Conceptual: which represents the concepts in the domain
  2. Specification: whose focus is on the interfaces of Abstract Data Type (ADTs) in the software.
  3. Implementation: which describes how classes will implement their interfaces.

Relationships between classes

Classes are interrelated to each other in specific ways. In particular, relationships in class diagrams include different types of logical connections. The following are the types of logical connections that are possible in UML:

  1. Association
  2. Directed Association
  3. Reflexive Association
  4. Multiplicity
  5. Aggregation
  6. Composition
  7. Inheritance
  8. Realization

I chose this topic because I am interested in Software Development and UML Class Diagram is an important tool for software engineer. Class diagrams are the heart of UML. They are based on the principles of object orientation and can be implemented in various phases of a project. During the analysis they appear as the domain model where they attempt to create a representation of reality.

Working on activities in class and homework on UML Class Diagram made me understand more easier how to write programming projects. It’s simple, easy to read and today I can write a code based on a UML diagram or design a UML diagram while writing a code based on what project I want to do. Class diagram gives a sense of orientation and provides detailed insight into the structure of the systems. Class diagrams are a vital part of any software development project and they form the foundation of all software products.
