Docker Reviews

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.

Pros

It uses containers instead of virtual machines, which makes it faster and smoother for running programs.

Cons

The security feature of using a SSH passkey might be confusing the first time you use Docker.

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.

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.

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.

Alternatives Considered

Reasons for Choosing Docker

Switched From

Pros

Using docker has been a relief for me having my application in a safe place to put them during the development stage has been good always.

Cons

This tool is using a lot of my CPU space

Pros

Running containers is way faster than running complete virtual machines, which makes Docker faster and smoother.

Cons

When first using Docker, it might be confusing with the terms of container, image and volume. After a while you actually understand them.

Pros

Effortless deployment, easy to adopt to any (of our) projects.

Cons

On windows made a mass on an Azure VM we use for development.

Pros

It's smooth for running different programs, provides an user-friendly interface, giving the best experience to everyone.

Cons

The installation process was kind of confusing, I didn't manage to understand the documentation.

Pros

The easy deployment of Docker and the fact that it doesn't take not much space makes Docker a great alternative for VMs and a great tools for production

Cons

When it comes to using docker, you must have a little bit of knowledge about OS and OS system configuration.

Pros

Application dependencies can be packaged alongside an application using Docker's containerization, guaranteeing consistency between environments.
Docker's container isolation enables applications to run independently, avoiding conflicts and ensuring scalability
Docker simplifies the deployment process by providing a standardized way to package, distribute, and deploy applications.

Cons

A learning curve is introduced by Docker, especially for people unfamiliar with containerization concepts. Gaining familiarity with Docker commands and best practices, can take some time.

Pros

Docker allows immense flexibility in running software before shutting it down leaving it ready for use at a later date. As a result it is highly configurable, needs fewer resources, is more secure and allows a range of tasks to be completed that would otherwise be impossible on a single server.

Cons

Complex to configure individual containers, depending upon the exact spec you want. You are running headless servers so need to ensure you cater for any situation that will likely crop up during execution.

Pros

The ability to use it on any enviroment, a little bit complicated to learn at first of course, but the benefits outstand the complications.

Cons

I guess it would help for beginners to have a little bit more easier information and documentation.

Pros

The ease of use and integration with our current toolset, while also having an extensive library of documentation

Cons

Nothing not to like, it works out the box.

Pros

I can state with certainty that it has helped me avoid a lot of time-consuming problems with software deployment. Our large project can be divided into smaller components, which we will then deploy in containers to enable independence. We can provide the appropriate environment needed to run our project using a Docker Image file. Applications can be set up and executed more quickly with the help of a large selection of pre-built containers.

Cons

Images can occasionally be quite huge, and Docker can use quite a lot of CPU and memory on a computer. On systems with little setup, it ages. For it to function effectively, a decent system is needed. The performance of Docker Desktop might be enhanced.

Pros

A very useful tool for creating containers and producing new things

Cons

In some cases, it gets complicated when dealing with the problems of new virtual machines created.

Pros

Docker is very portable. It can run on any system regardless of the underlying infrastructure. This makes applications easy to move within different environments.

Cons

Docker can be challenging for new users because it has really complex concepts and commands. A new user might not understand containerization or container orchestration.Image sizes are quite large and may slow down the machine's perfomace.

Pros

Docker containers consume fewer resources compared to traditional virtual machines and they also encapsulate applications and their dependencies into self-contained units.

Cons

It took me so long to actually understand what it did, and most documentation on the service was hard for a newcomer. Docker networking can be complex, especially when dealing with advanced network configurations or integrating containers with existing network infrastructure.

Pros

Creating software containers for cloud deployment.

Cons

As to be expected, it has a bit of a learning curve.

Pros

Docker is a game-changer when it comes to containerization. Its simplicity and ease of use make it the go-to choice for managing and deploying applications in containers. Which is the main key for my team.

Cons

i don't have anything negative to say about this tool.

Pros

Its nice for containerization of software application and really versatile in deployment.

Cons

Nothing really all around great product to use.

Pros

docker allows you to test applications without having to install them. it allows to make POC quickly and to choose the right application.

Cons

Sometimes is better to use unix container :-(

Pros

The main benefit of docker is that it ensure the applications runs the same way on any machine. Dockerized applications can be easily moved between different environments without any compatibility issues. Also we can run multiple containers on a single machine making the most efficient use of available resources. Docker containers can be quickly deployed and scaled. Very lightweight and portable.

Cons

There is a learning curve associated with Docker, particularly for developers who are new to containerization. Docker is designed to work with modern, cloud-native applications, and may not be the best choice for older, legacy systems.

Pros

User friendly with little knowledge. Straight forward and obvious

Cons

cost is always the con of anything. Otherwise very happy with the experience
