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.

Docker is an open-source software that is used to deliver Linux and Windows images into virtual containers. According to this article, containers use shared operating systems, meaning that they are much more efficient than hypervisors in system resources terms. Instead of virtualizing hardware, containers rest on top of a single Linux instance. This means that 99.9 percent of useless VM junk is left behind, so we can have a small container containing necessary applications.

Specifically, container technology just abstracts the operating system kernel while the VMs hypervisor abstracts an entire device. Meaning that containers allow data center operators to cram much more workloads into less hardware. Furthermore, containers are portable, each instance is stored standalone in a port. It means that Docker allows you to run multiple copies of the same image in different local ports.

Another reason why Docker is so popular is its installation, downloading a whole application, for example, a database service, is usually frustrating since we have to follow strictly step by step, and if we mess up somewhere, the application will not function properly and we have to fix or reinstall the whole app. Docker is encapsulating the whole application into a container, to install a container to use locally, developers simply pull it from Docker Hub, which I will introduce below, with a command and run it.

Docker Hub is the largest library and community for container images, where users are able to find what image, container, command they need and share what they have to others. Just like GitHub, you will create an account and use it to fetch and push the source code or pull it from other people, but the repositories here are containers, image repositories. For instance, you need to set up the MySQL database for your application, instead of downloading and setting up the port for one database, you will look for it on Docker Hub and install it based on the repositories’ instructions and connect it to your computer port through a port. By the time this blog is posted, there are almost eight and a half million available images on Docker Hub for users to pull and work with.

In conclusion, Docker has revolutionized software development by making things possible. It gets more applications running on the same hardware; it is quick and simple to initiate an instance, therefore it makes managing and deploying applications much easier.

So I know I’m quite late to the topic, but way back in week 1 or 2 we went over the POGIL roles, responsibilities and basic structure. This for me has always been about learning to work in a team, regardless of the assigned jobs on the card – and I have to admit I’ve always had a hands off approach. I wouldn’t say I’m a bad team member, just an absent one. I wasn’t always engaged, and just wanted to meet some arbitrary requisite for a good enough grade. I’ve obviously adapted as projects and activities got harder, but this podcast episode seems to have broken me out of that passive mindset into something much more productive.

There is a bit of a disconnect here from myself to the podcasters, as they are experienced developers with years of managing experience, but nonetheless I think it helped me glance into a world that I knew absolutely nothing about. Kind of like a peek behind the curtain of what I should be expecting. My greatest takeaway is always defer to someone who has even a tad more expertise with a certain context. There’s simply too much to keep up with, and in order to do your job effectively, one must make a choice to lean into a specific type of architecture. Just be good at what you’re supposed to be good is my takeaway, I guess. Other peoples’ expertise will help whatever the team is working on, and your personal experience will almost always prove to be invaluable at some point in the project.

In addition, I think I’ve picked up a habit of deferring to other peoples’ techniques when solving a problem. I of course will point out if I think I see an error or bug, but it gives me a sense of wonder seeing how many different solutions people can come up with to a singular problem. There is so much ingenuity inherent to coders that it’s never a good idea to say “this is the way things should be done.” My father is an architect who advises some up and comers, and when I ask him, he is regularly annoyed with staff for not doing things “the right way.” I love the guy, don’t get me wrong, but after listening to the episode I have to say that this technique is too suffocating. Just like in architecture, writing code is an expression of will or intent through creation. To limit that in either capacity is unhealthy for the people who would pour their heart into the work.

I suppose that’s a bit philosophical, but nonetheless it’s a lesson I’m glad that I’ve been exposed to. Other nuggets in the episode are tips on efficiency and cohesion, but these two concepts are what really stuck with me.
