What do you dislike?

With Docker, all containers must use the same operating system and kernel.

What do you like best?

Docker has made containers easier and safer to deploy and use than previous approaches. Docker makes it possible to set up local development environments that are exactly like a live server,

What do you dislike?

The image build time could be slow. It could be mitigated by property designing the Dockerfile.

What do you like best?

(1) Easy of Use. My primary pain was to set up PHP and Nginx on my Macbook. With Docker, I just need to run a single command. (2) Vendor Support. Lots of cloud provider (e.g. Amazon Website Service) supports Docker natively. I am using container service provided by Amazon Website Service with Docker

What do you dislike?

Docker networking is pretty bad

Cleaning up stale images and left over stuff on machine needs to be automated

There was also a recent buggy release that didn't handle image cleanup correctly

What do you like best?

The performance is AMAZING compared to running apps inside virtual machines.

Constructing docker images is a breeze, dockerfiles make creating app containers straightforward.

Perfect for running micro-services, and great support on Kubernetes.

Recommendations to others considering the product

Definitely give it a shot, especially if you are running micro-services

What do you dislike?

Docker can be a bit cumbersome to use and has a steep learning curve. Almost everything is done through rather cryptic command line tools that are not entirely intuitive.

What do you like best?

Docker allows us to create an image of a code repo and deploy it through environments. The best feature of docker is the immutability of a docker image. Once it is created it can not be changed, so you know that your code will be the same in the test environment as the production environment.

Take the time to do some tutorials on how to create a Dockerfile and a docker-compose file correctly. Once you figure out how exactly those work docker can actually be pretty simple

What do you dislike?

Docker container are enormous, bloated, and slow. A "Hello, World" Node.js container will be upwards of 650MB and take an eternity to build. Also, Docker solves the very easy problem of running an application in isolation but doesn't have a solid story about running a fleet of applications. Also, dangling Docker images cause regular disk space shortages and its tricky to manage them.

What do you like best?

There's a lot of great tooling around docker because it's so standardized. Mesos and Marathon, in particular, work quite well with Docker, and Docker hub is great.

If you're already skilled with Docker or hired someone who is an expert with Docker then I'd say go for it. But learning Docker is a tedious and painful process, and managing it in production without several years' experience is a minefield. Consider whether you really need Docker or you can just build statically linked binaries.

What do you dislike?

the set-up can be a little tricky, but once you understand the basics you are good to go.

What do you like best?

It is very easy to organize and deploy. Gives you the ability to maintain the same environment for development and production, and has a big library of code to search for similar applications that will help you.

Recommendations to others considering the product

It is very useful and has a wide variety of apps ready to be deployed on your local machine on dockerhub. you can also maintain your own repos there privately to share with your coworkers that way all are using the same app repo.

What do you dislike?

That in some old computer can't to run, but is understandable

What do you like best?

I like the flexibility to app deployment and the lot of images available; I like as with Docker I can to have lots softwares running at the some time; Also, the better that Docker have a version CE

Recommendations to others considering the product

it a new way of manages your apps, it is great

What do you dislike?

Some amazing new feature with some bugs so needs to balance the feature and stability. Sometimes try to dig workaround but learn more from detail.

What do you like best?

Simplify tool setup and easy to use with minimize host system requirement and maximum the system usage.

What do you dislike?

Most common software is available, others aren't. For those that aren't you need to create the image and that can take some time. But of course, after you create the first one, you can save it and share it with others.

Also, networking between containers in different hosts is still tricky.

What do you like best?

With docker, your able to run containers in a very easy way. You can browse image containers (system templates) in the container hub (central repository) and look for official and community images. You can try all sorts of software and services in a sandboxed environment, without affecting your system. You can also create your own images based on a scratch one or one available in the hub. You can also create your private hub to store private images of your software.

Reproducing a similar environment (like development, staging and production) was never this easy.

Recommendations to others considering the product

By far, the best solution to ensure you have a consistent production environment, avoiding situations like "it worked in my computer".
