DOCKER FOR MAC | HOW TO INSTALL & WORK BEST GUIDE 2022

This blog post will provide a guided tour of what Docker For Mac is, how it works, and why it’s so great! Docker for Mac is a software solution that makes it easy to deploy applications inside containers. With Docker for mac, you can create and run containers with all of the necessary dependencies required to run an application in production without having to worry about configuring your operating system or installing any packages.

What A Docker Small Intro

Docker is an open-source project that automates the deployment of applications inside software containers. Software containers are similar to virtual machines (VMs), but they’re much lighter and add additional layers of abstraction above VMs by utilizing what’s called a “libcontainer”. Libcontainers can be created in seconds and do not require several prepared layers for booting, which makes them a strong alternative to VMs.

Docker for mac was originally invented by a company called dotCloud, and several open-source projects started building on top of it in order to solve problems with Docker’s core implementation. This led to the creation of the Open Container Project (OCP), which aimed to create a standard specification for creating, distributing, and running containers. Today, Docker is a company that maintains a commercial product based on this same open-source technology.

How to install Docker on Mac

Build your own machine here: http://www.docker.com/products/overview

You can get the docker for mac here: Click Here

To buy it you need to create an account here: Click Here

After installation:

When you open it for the first time, you will see a welcome screen and some prompts. You need to accept the license agreement. And then the application asks if you want to be signed in automatically or not. If so, give your username and password here. Or else leave it blank to start the configuration.

After that, you will see this screen:

You can see your Docker for mac IDs and passwords and also check for updates and maintenance releases. Down the bottom is a ‘terminal’. It has three entry points: bash, sudo, and compose. If you need to do some advanced stuff then using the terminal is good because it’s like the terminal on your Ubuntu machine.

How does it work?

Docker manages the creation of containers by utilizing the App Container (appc) specification. When you create an application container, Docker downloads the image from a remote registry, creates a copy of it on your machine, and executes the application. Docker ensures that each running application will have its own isolated environment with all of its dependencies.

Let’s try this out! First, let’s start by making sure that you have docker installed on your machine. You can verify that it’s installed correctly by running docker –version. You should see Docker version 17.03.1-ce in the output, which means you have it correctly installed!

## Creating your first container Let’s start by creating our first container. First, we’ll need to create an application image on the remote registry so that other containers can pull this image to their host. To do so, we first need to pull one of the example images on Docker’s registry. Run docker pull hello-world.

Done! You now have an application container image that you can run by executing docker run hello-world. This will download and execute the hello-world application inside a container. The hello-world application simply prints out “Hello World” and exits after running for a few seconds.

To verify that your container is working correctly, you can run docker logs <container id> to see the output of the program as it ran inside the container. To get this container’s id, we’ll need to first run docker ps.

You should see the container id printed out to the output. Now, you can run docker logs <container id> in order to verify that your container works correctly!

why it’s so great

Docker containers are extremely lightweight. They don’t require much disk space or RAM because each container has its own filesystem by default, which means that your system will only keep the filesystem changes that were made to your applications instead of maintaining an entire copy of them at all times. Even though running a single container doesn’t take up too many resources, the most important feature of Docker for mac is its ability to run multiple applications simultaneously without affecting each other.

In comparison with VMs, containers have a much smaller overhead because they share the kernel of the host system. This means that your machine doesn’t need as many resources in order to run more containers at once — In fact, this is one of the selling points of Docker. The ability to run several different containers on one machine with only a few resources is what makes it great for running CI (Continuous Integration) tests on your local machine, which may require several builds at once (e.g., if you’re building an app that requires some node modules to be installed).
