It also means you dont need to state the file name when using the docker build command.

Docker No Kubernetes Software At Scale

When bringing up these trends its hard to ignore some of the big names, like Kubernetes and Docker, which have for lack of a better word, revolutionized the way we develop and deploy software at scale.

Its a set of platform-as-a-service products designed to solve the many challenges created by the growing DevOps trend.

Docker makes it easier to create, deploy, and run applications with the use of containers.

They create an abstraction at the app layer that packages your application and dependencies with everything it needs to run including: the operating system, application code, runtime, system tools, system libraries, etc.

These containers need to be deployed, managed, and connected and updated; if you were to do this manually, youd need an entire team dedicated to this.

The real benefits are obtained with tools that sit on top of containers like Kubernetes.

They are not competing tools, so there shouldnt be any confusion around, should I use one over the other or which one is better.

As mentioned earlier in this post, its not enough to merely run containers in production, they need to be regulated and Kubernetes offers some great features that make working with containers even easier.

Kubernetes offers things like auto-scaling, health checks, and load balancing which are crucial to managing the container lifecycle.

You can think of it as an isolated machine, or a virtual machine if you prefer.

It cannot see the other containers, physical storage, or get incoming connections unless you explicitly state that it can.

It contains everything it needs to run: OS, packages, runtimes, files, environment variables, standard input, and output.

Which means you could host both versions on the same server.

An image describes everything that is needed to create a container; its a template for containers.

You may create as many containers as needed from a single image.

In the example above, the app2 image is used to create two containers.

Each container lives its own life, and they both share a common root: their image from the registry.

This message shows that your installation appears to be working correctly.

If you have a desktop version of Windows that doesnt meet the requirements, you may use the older Docker Toolbox based on VirtualBox.

Double-check them if you cannot successfully run the hello-world test.

Inside our images, we can stuff our programs and their dependencies so that multiple containers can be created from those images and live happily ever after.

The Dockerfile file contains instructions on how the image should be built.

Naming it Dockerfile makes it easier for others to understand its purpose when they see that file in your project.
