Dockerの評判・口コミ 全65件

What do you dislike?

It has a steep learning curve, it took me a while to get acquainted with.

What do you like best?

Docker helps me to easily deploy my app to our company's remote server. Also, it by using the same images, Docker guarantees that everybody who's using the same app, has the same code and configurations.

Make sure to read the documentation before using it.

What do you dislike?

Docker for Mac is extremely slow when mounting volumes from the host system into the container.

What do you like best?

Lightweight

Easy to learn

Easy to distribute the images

Name spacing

Infrastructure as code

Dev-Prod Parity

Recommendations to others considering the product

Don't go after the fad. Introducing Docker in your workflow needs a lot of beforehand thinking. Discuss and prove the usability of Docker in your organization and only then get ahead. Above all, do get a strong hold of the basics of Docker

What do you dislike?

The docker image building speed can be faster

What do you like best?

The cleanness of the isolated environment

Recommendations to others considering the product

Better use it with docker-compose

What do you dislike?

The initial set up is complicated if you've never used it before. Not to say impossible, but there are several different ways to install docker and finding the "best" way can be tricky.

What do you like best?

The ability to replicate environments and distribute software that is guaranteed to be idempotent is very nice

Recommendations to others considering the product

It's very powerful and once everything is set up properly, it's a set-and-forget type of deployment

What do you dislike?

need clarity on how to cleanup extra volumes, old images, overall cleanup.

What do you like best?

Reduces dependencies, able to share docker configs with co-workers, written on Go.

Recommendations to others considering the product

Learn how to maintain and clean up images and volumes on your server.

What do you dislike?

There is a steep learning curve to understand how everything in Docker works together. You will have to read a lot of documentation to get going and there are not a lot of machine learning tutorials for Docker. Also, Docker does not clean up after itself. Make sure that you get rid of any dead containers to save on memory and storage space.

What do you like best?

I was able to develop a machine learning application on my local machine and then deploy it on a remote server without changing any of the source code. If the app worked on my machine, it would work anywhere with a simple pull from the Docker service.

What do you dislike?

Command line can be obscure, desktop client can be feature-poor.

What do you like best?

The ability to get a virtual environment up and running in mere seconds, rather than installing a whole OS inside of a virtual machine.

Recommendations to others considering the product

Prepare to learn an entirely new category of deployment and systems management, but it is very worth the effort.

What do you dislike?

A few small issues but takes a lot of time to work around. The Docker images are somewhat stateless and creating persistent storage is extra effort.

What is dislike most is to answer the question: "What is the Future of Docker?" when I get asked by our internal sponsors. It doesn't seem as bright as it was 3 years ago.

What do you like best?

Docker has saved us thousands of hours in patching and downtime. Spinning up a virtual instance in our SaaS environment was always a challenge, Docker made it possible. From Dev -> QAS -> Sandbox -> Stage -> Prod it has saved us time, money and possible embarrassment.

Recommendations to others considering the product

If you are still in the planning phase and haven't implemented Docker yet, please know the future before you start deep dive discussions.

Rest assured, as of today (or couple of years ago), it was obviously going to save us time, money and effort. We've been able to achieve near 0 downtime patches, upgrades etc and with lot less manual errors. The way to manage patching in different data-centers has been overly simplified. The developer edition is free and Enterprise edition is really worth couple of thousand $$. Since it is mostly community driven, don't always rely on getting free fixes, feel free to fix it as well :)

What do you dislike?

Docker container is not standalone, means you can't run it instead of an OS.

What do you like best?

Docker is extremely configurable and performs better than a virtual machine. Virtual machine has their own memory management, thus possess extreme overhead on the host system. While the Docker container runs as an application, could be started in few seconds and the applications in the container perform same as the virtual machine

Recommendations to others considering the product

Just use it. It's easy to setup. In my case, I have a shell script prepared by another developer which I run to deploy the application. So no hassle for me.
