About Docker
Docker is an on-premise and cloud-based application development platform that helps businesses build, test and share containerized applications and microservices. Using the Docker Engine, professionals can run and distribute developed applications across various infrastructures and operating systems such as CentOS, Fedora, Oracle Linux, RHEL, Ubuntu, Windows Server and more.
Administrators can integrate the platform with multiple development environments and utilize Docker APIs to facilitate collaboration among operational teams. It allows organizations to design applications using customizable templates, create and share container images in a private registry and streamline the installation and management of application configurations. Additionally, it provides developers with tools to build Kubernetes-ready applications on a centralized platform.
Docker enables businesses to develop applications in compliance with open container initiative (OCI) specifications. Pricing is available on monthly subscriptions and support is extended via documentation and an inquiry form.

Streamlining development and deployment
Pros
It encapsulates applications and their dependencies onto light weight containers. Keep consistency in all environments, from the local environment to the development environment.
Cons
Configuring and optimizing containers is not easy. It requires expertise. And if not done properly, security concerns can arise.

An essential companion in my development environment.
I replicate locally the setups of all my remote server via docker compose. With docker you can have multiple versions of the same service without risk of collision or incompatibilities.I use it on wsl on windows and it works like a charm.
Pros
I work in web development industry, with docker you can replicate on your machine any setup, (web server, database, smtp) , so that you can build your application in an environment that is almost identically to production one.
Cons
I find that the learning curve is steep, so you have to struggle in the beginning to master the tool. Sometimes containers are resources' hungry, so adequate monitoring is needed.

Docker has gone the way of the dodo
Started out great, then turned to not-so-great, then eventually GET ME OFF THIS THING.It took them coming out with an Open container initiative to be able to market their product, which is bloated cruftware. There are better options out there. Maybe not as user-friendly, but definitely not as buggy.
Pros
It was awesome the day we replaced it with something else. I suppose it's a good dashboard app for showing off running containers on your workstation.
Cons
It's too resource intensive, and makes everything else crash when I'm running the containers. I hate how they force you to upgrade to the latest version if you're a freebie, and that usually breaks all my keys on boxes, which means I've got to reset to factory defaults just to use what I already had working. Docker is literally a productivity killer because they think they know more about virtualization than you do and so they push updates and force you to download them and occupy all your hard-drive with bloated containers.

Docker: Light weight Container Setup and Configuration
Pros
I have used Docker to run multiple Java and Python virtual environment in sandboxed isolated containers on Ubuntu Linux. The main motivation was to support the testing of different Application server versions using Apache Tomcat and Oracle JDBC drivers. Docker containers saved us a lot of time that we used to spend on creating and configuring virtual machine and more importantly enhanced greatly the performance and throughput of the testing services. We were able to execute multiple Oracle instances using the Docker containers and creating isolated client/server applications using the Socket API on top of it.
Cons
I expect to see more support for containerized applications on multiple machines and more scalability, resiliency, and fault tolerance as in Kubernetes.
