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.

Hello,

I am doing some class activities and looking over some questions ahead to save time for a thing or two. I came across the word “Behavioral Patterns” in class Act. 4 (Model 8); I got curious and looked it up. I found two articles that helped me understand the purposes, Problems with solutions, Real-World Analogy, Structure, Pseudo-code, Applicability, How to Implement, Pros and Cons, Relations with Other Patterns.

The Behavioral Patterns are concerned with providing solutions. It is about object interaction – how they communicate, how some are dependent on others, how to separate them to be both dependent and independent, and give both flexibility and testing capabilities—also, the assignment of responsibilities between objects.

The Behavioral Patterns cover many small parts to form the full extend of patterns. Like Interpreter, Template Method/Pattern, Chain of Responsibility, Command, Iterator, Mediator, Memento, Observer, State, Strategy, and Visitor.

Interpreter

The Interpreter pattern: Evaluate any language grammar or expressions. An excellent example; this pattern would be Google Translate, which deciphers the input, and shows us the output in another language. Another example would be the Java compiler. The compiler interprets Java code and translates it into byte-code that the JVM uses to perform operations on the device it runs on. Also, it represents a great way to write simple programs that understand human-like syntax. 

Chain of Responsibility – pass requests along a chain of handlers. Upon receiving a request, each handler processes the requestor gives it to the next handler in the chain. 

Command – Turns a request into a stand-alone object that contains all information about the proposal. This transformation lets pass requests as a method arguments, delay or queue a request’s execution, and support undo-able operations. 

Iterator – traverse elements of a collection without exposing its underlying representation (list, stack, tree, etc.)

Mediator – it reduces chaotic dependencies between objects. The pattern restricts direct communications between the entities and forces them to collaborate only via a mediator object.

Memento – it saves and restores the previous state of an object without revealing the details of its implementation.

Observer – define a subscription mechanism to notify multiple objects about any events to the observed entity.

State – lets an object alter its behavior when its internal state changes. It appears as if the thing changed its class.

Strategy – define a family of algorithms, put them into a separate class, and make their objects interchangeable.

Template Method – the outline of an algorithm in the super-class but lets sub-classes revoke exact steps of the algorithm without modifying its structure.

Visitor – It separates algorithms from the objects on which they operate.
