Docker

For QA

Vantagens:

O jeito fácil e rápido de subir um ambiente totalmente virtualizado é o diferencial do Docker, além disso a biblioteca de imagens tem praticamente todos os serviços, softwares que podem ser facilmente usados.

Desvantagens:

Talvez o preço seja um pouco salgado para aqueles que precisam de um store maior e ao mesmo tempo com mais performance.

Avaliação

Vantagens:

Praticidade para desenvolver e utilizar ferramentas em um ambiente sem interferir no ambiente local

Desvantagens:

Cache no build da imagem não possui fácil gerenciamento

World changing containers and standard de-facto

Comentários: Docker was first (I believe) on themarket of containerized software. There was a lot of talks that it is nothing more than an interface to unix cgroups and that docker has no future, this is just hyped piece of software.
Time proved them wrong. Docker became a standard solution, participated in Open Container Initiative and while fully comply with all the OCI requirements, docker is used much widely.
Container solves library/dll hell - that means that you may have two application that require incompatible libs running on the same computer without any problems. Applications are separated, they can't affect each other, their resource consumption may be tuned using docker tools.
You may build proof of concept wiring containers into a single docker-compose and have the whole stack running here.
Multi stage build allows to build software which does not have access to any secrets used during build step.
You may use tons of software without installing it, just by running them in the docker.

Vantagens:

Great documentation. Easy to use. Exists on any OS and platform you may need it (doesn't work with latest ARM Mac yet, but I believe this is a matter of time). Allows to you to use any software / platform / solution you want without actually installing it on your computer. Docker-compose may ran the whole stack right on your laptop and multistage builds takes care of safe software building. Free docker registry on top of that. Tremendous amount of how-to.

Desvantagens:

Some functionality behaves differently depending on platform. For example - mounted volumes. Some of issues related to file permissions stays there for at least few years. Internal volumes can not be extracted and moved to another computer easily, which somehow defeats it's purpose. Doesn't play well with WSL/WSL2 and especially if you pair it with build in kubernetes.

The lean virtual machine tool we've been waiting for

Comentários: Feels like a bit of a learning curve coming from using VirtualBox, vagrant, etc., but when you get that first cluster of virtual environments running interacting apps you know how worth it it was

Vantagens:

Docker works on every platform and makes it simple to match production and development systems. It's similar to older virtual machine and VM management tooling, but much more lean and 100% open source.

Desvantagens:

Getting started can be intimidating. While it's worth the time invested, development teams accustomed to working directly on their own hardware or with traditional virtual machine tools will have a bit of a learning curve.

Docker has gone the way of the dodo

Comentários: 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.

Vantagens:

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.

Desvantagens:

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.
